Terminology Usage

Attention! The term

Use of reserved areas can cause compatibility problems, loss of data, or permanent damage to the hardware. When the contents of a register are changed, the state of the reserved bits must be preserved. When possible, read the register first and change only the bits that must be changed.

In this manual, some signals are represented in a small, all-capital-letter format (-ACK). A minus sign in front of the signal indicates that the signal is active low. No sign in front of the signal indicates that the signal is active high.

The use of the term “M” and “G“ are used, they typically indicate powers of 2, not powers of 10. For example, 1 KB equals 1024 bytes (210), 1 MB equals 1 048576 bytes (220), and 1 GB equals 1073741824 bytes (230).

When expressing storage capacity, MB equals 1000 KB (1024000). The value is determined by counting the number of sectors and assuming that every two sectors equals 1 KB.

Note: Depending on the operating system and other system requirements, the storage capacity available

to the user might vary.

SCSI Adapter

Some computers come with an Adaptec SCSI-II Ultra Wide adapter installed in one of the expansion slots. This adapter provides an interface between the PCI bus and SCSI devices. SCSI technology is useful with multitasking operating environments because instructions can be sent concurrently to every drive in the system, and the drives can then execute these instructions simultaneously.

An extra cable is provided with SCSI models. The cable included with the PC 300GL Type 6275 has four connectors: one connector for attaching the cable to the SCSI adapter and three connectors for attaching optional SCSI devices. The cable included with the PC 300GL Type 6285 has five connectors: one connector for attaching the cable to the SCSI adapter and four connectors for attaching optional SCSI devices.

For information on the adapter and connecting SCSI devices, refer to the SCSI documentation that comes with the computer.

Cabling Requirements for Wake on LAN Adapters

Wake on LAN adapters have two headers: a 3-pin, right-angle header for providing AUX5 (Auxiliary 5 volts), and a 2-pin straight header for connecting the wakeup signal to the system board (or riser card). The PC 300GL and 300PL have a 3-pin header on the riser card that provides the AUX5 and wakeup signal connections. The Wake on LAN adapter option will provide a Y-cable that has the 3-pin riser card connector on one end and splits into the 3-pin and 2-pin connectors required to interface the card. When a Wake on LAN adapter is installed in the system and attached to the AUX5 power, the system board Ethernet function must be disabled via switch 6 on the system board (refer to “System Board Switches” on page 14 for switch information).

Chapter 3. Physical Specifications 23

Chapter 4. Power Supply

The power supply requirements are supplied by 145-watt PC 300 Types 6275/6862 (desktop models) or 200-watt PC 300 Types 6285/6892 (tower models) power supply. The power supply provides 3.3-volt power for the Pentium microprocessor and core chip set and 5-volt power for ISA and PCI adapters. Also included is an auxiliary 5-volt (AUX 5) supply to provide power to power management circuitry and the system board Ethernet function, or a Wake on LAN adapter. The power supply converts the ac input voltage into four dc output voltages and provides power for the following:

System board Adapters Internal drives

Note: Some adapters and hard disk drives draw more current than the recommended limits. These

adapters and drives can be installed in the system; however, the power supply will shut down if the total power used exceeds the maximum power that is available.

Output Protection

The power supply protects against output overcurrent, overvoltage, and short circuits. See the power supply specifications on the previous pages for details.

A short circuit that is placed on any dc output (between outputs or between an output and dc return) latches all dc outputs into a shutdown state, with no damage to the power supply. If this shutdown state occurs, the power supply returns to normal operation only after the fault has been removed and the power switch has been turned off for at least one second.

+5.0% to −5.0%

If an overvoltage fault occurs (in the power supply), the power supply latches all dc outputs into a shutdown state before any output exceeds 130% of the nominal value of the power supply.

Connector Description

The power supply for the PC 300 Types 6275/6862 have four, 4-pin connectors, and the PC 300 Types 6285/6892 and have six, 4-pin connectors for internal devices. The total power used by the connectors must not exceed the amount shown in “Component Outputs” on page 26. For connector pin assignments, see Appendix A, “Connector Pin Assignments” on page 52.

Advanced Power Management (APM)

The PC 300PL and PC 300GL computers come with built-in energy-saving capabilities. Advanced Power Management (APM) is a feature that reduces the power consumption of systems when they are not being used. When enabled, APM initiates reduced-power modes for the monitor, microprocessor, and hard disk drive after a specified period of inactivity.

The BIOS supports APM 1.1. This enables the system to enter a power-managed state, which reduces the power drawn from the ac wall outlet. Advanced Power Management is enabled through the Configuration/Setup Utility Program and is controlled by the individual operating system.

For more information on APM, see

Chapter 6. IBM System Management Tools

IBM System Management Tools are a collection of hardware and software features designed to make it easier to manage your system over a computer network. When used in conjunction with the appropriate network management software, these tools provide systems administrators the ability to remotely manage and monitor your computer.

IBM System Management tools consist of the following components:

Desktop Management Interface (DMI) Service Provider 2.0 Desktop Management (DM) BIOS 2.0 Instrumentation IBM PC System Monitor Instrumentation

IBM AssetCare

IBM Alert on LAN IBM SMART Reaction Client Intel LANDesk Client Manager 3.1.

When you install IBM System Management Tools, all of the essential components are installed. However, you can choose whether to install the two optional tools, Intel LANDesk Client Manager and IBM SMART Reaction Client.

IBM Alert on LAN requires additional hardware support. This support is provided with some computer models only.

For OS/2 Warp V4.0, only DMI Service Provider, DM BIOS Instrumentation, and IBM AssetCare are supported.

Components of IBM System Management Tools

A description of each of the components of IBM System Mangagement Tools follows:

DMI Service Provider

The Desktop Management Interface (DMI) Service Provider 2.0 is a mechanism for gathering information about the hardware and software in your computer. It is used to help administrators manage and control hardware and software products on desktop computers and network servers. The DMI Service Provider can be used to remotely track information such as serial numbers, memory attributes, product-specific characteristics of installed peripherals, and operating system information from each DMI-compliant component and manage that information in the Management Information Format (MIF) database. The service provider passes this information to management applications as requested. This information can be accessed using a DMI browser. DMI browsers are provided by all major operating systems and all major LAN management packages, including TME 10 NetFinity, Intel LANDesk, and Microsoft SMS. It controls communications between itself and manageable products by means of instrumentation. Support documentation is built into the browser's Help system.

DM BIOS Instrumentation

This application retrieves information such as memory configuration, BIOS version and date, and microprocessor and cache information from the system BIOS.

30 Copyright IBM Corp. June 1998

Chapter 6. IBM System Management Tools

IBM PC System Monitor (LM80)

This application monitors system-board temperatures, system voltages, and fan speed, and detects removal of the computer cover. Data is reported to the DMI service provider. System management software, such as IBM NetFinity Services or Intel LANDesk Client Manager, can then be used to send an alert to the user or to the system administrator if a problem occurs. The IBM PC System Monitor must be installed in addition to NetFinity in order to enable environmental monitoring in NetFinity (PC System Monitor and NetFinity can be installed in either order).

System Management Chip

The PC300PL contains a National System Management chip (LM80) that provides low cost instrumentation capabilities for a PC in order to lower the total cost of ownership over the life cycle of the PC. The System management chip monitors the system at all times looking for potential failures before the system fails. Notification can be provided across the LAN.

System Management controller monitors the following:

System temperature sensing and fan control Voltages (+5,+12,-12,+3.3,+1.5,2.5, and -5) Intrusion detect for security (detects when chassis lid has been removed, even if power is off). Uses

mechanical switch in the speaker/fan assembly.

Serial Bus interfaces (SMBus version)

These hardware functions allow the LCM, LCCM, and LDCM Network software to remotely monitor the client PCs over the network for these critical parameters. When machines are found with out-of-range parameters, appropriate repair, backup, and shutdown actions may be taken.

The LM80 physically resides on the SMbus interface. The device address for the LM80 is 0x50 hex . The SMBus protocol is used to read/write data to/from ALL registers onboard the LM80. There is a

protocol established for reading and writing these registers to maintain consistency in the eventuality that the thread is broken (context switch) while servicing it. Each of these registers and their functionality is spelled out in the Software Interface section of this document.

LM80 contains virtually all the signal conditioning and front end analog circuitry necessary to interface to the power supply voltages, fan and chassis intrusion alarm onboard as well as having a fully self contained temperature sensor. An SMbus (Integrated Circuit, 2 wire serial) slave bus interface is also provided for future compatibility with other SMbus devices.

At initial power on configuration, the LM80 will be programmed with predetermined threshold values for temperature, voltage, and fan control. During system operation IBM PC System Monitor code polls the LM80 and generates an alert when the measured value is outside of the programmed min and max range.

System Management Bus (SMBus) Controller

PIIX4E contains a SMBus Host interface to allow the CPU to communicate with SMBus slaves. The PIIX4E also provides an SMBus slave interface to allow external masters to monitor power management events. The SMBus controller is logically a subset of the PIIX4E power management controller.

Chapter 6. IBM System Management Tools 31

Chapter 6. IBM System Management Tools

Power Management Controller

PIIX4E contains support for advanced power management features, including clock control, and various low-power state control logic. In combination with the onboard battery backed RTC logic, the PIIX4E provides full hardware and software based power control. It contains full support for the Advanced Configuration and Power Interface (ACPI) specification. APM is also supported for "legacy OS's." These features are controlled via software.

PIIX4E supports the following power management functions:

Global and Local Device Management Suspend and Resume logic Supports Thermal Alarm Support for External Microcontroller (LM80) Wake up events supported:

– Wakeup from a LAN request. Used with the integrated planar Ethernet or Wake on Lan (WOL)

LAN adapters (Token Ring or Ethernet).

– Connectors for WOL LAN adapters located on Niagara BX Riser. – Wakeup from UART Ring Indicate ( Serial Port 1 only) – Wakeup on RTC date and time – Wakeup on switch input – Wakeup from external ring (used with internal modems). Connector located on Niagara BX riser. – Wakeup from a PCI PME# (PCI Power Management) event.

IBM AssetCare

This application is used to retrieve serial numbers and system configuration information. Serial numbers can be dynamically retrieved from IDE and SCSI hard drives, memory DIMMs, and DDC2B compliant monitors. Serial numbers for other system components, including CPU, CD-ROMs, system unit, riser cards, floppy drives, power supplies, and the motherboard, are readable from the Enhanced Asset Information Area, which resides in an EEPROM and can be accessed either through a radio-frequency link or through the system's SMBus.

The system BIOS determines the type of access to the Enhanced Asset Information Area EEPROM that is allowed. The EEPROM is partitioned into 8 blocks of 128 bytes each. Blocks 0-5 are reserved for AssetID data,which includes system and subsystem serialization data, system configuration data, and other system data that may be user specified.

The six blocks are grouped into three areas of two blocks each. The first two blocks (blocks 0 and 1) are referred to as the Serialization Information Area. These blocks are reserved for system and subsystem serial information. The data within the area consists of a 16 byte header followed by serial numbers. The User Information Area (blocks 2 and 3) is reserved for user information. This area consists of a 16 byte header and a 232 byte area and an 8 byte reserved area. The Configuration Information Area (blocks 4 and 5) includes an area header followed by the configuration data. The data stored in this area is maintained by the system BIOS at each boot time.

Data can be written and read through either the RF interface to the system or the SMBus. Writing and reading via the RF interface requires a portable hand held reader or door reader. Software residing in the hand held reader and portal gate controller are required to support the RF interface. Access to the EAI area data from the system side is provided by the DMI browser provided with the software.

When data is written to the EIA through the SMBus it is done either dynamically or statically and depends on the data. Dynamic update of some of the data is done either by the system BIOS or by the AssetCare software each time it is loaded by obtaining the information directly from the device or operating system. Other types of information must by entered and updated by a system administrator or other authorized person. All data entered into the EAI area must be associated with one of the device types defined in Figure 22. Although every device entered must use one of the device types defined, the inclusion of a specific entity in the EAI area is optional. However, to get maximum utility from the EAI hardware, the data should be as complete and accurate as possible.

System configuration information includes processor type and speed, hard drive size, and memory configuration as well as information about on-board devices. Both the serial number and system configuration information can be retrieved by system management applications as well as through radio-frequency (RF) hand held readers and RF access-control gates. The radio-frequency (RF) interface to the Enhanced Asset Information Area enables the customer to perform asset deployment, asset tracking / inventory, and asset access control. This function is referred to as Asset ID.

AssetID

The essential component of Asset ID is a radio-frequency interface within each PC that allows access to the EAI EEPROM data. The Asset ID antenna enables communication between the PC and industry-standard radio-frequency handheld scanners. The Asset ID EEPROM contains information about the system, including its configuration and the serial numbers of key components. The Asset ID EEPROM also includes a number of blank fields you can record with your choice of end-user information. Asset ID enables you to read and write information to an EEPROM inside an IBM PC by using a handheld scanner, even while the PC is still in the carton.

Asset ID allows you to take accurate physical inventories of systems and their components without searching for a label or opening the chassis. Passing the handheld scanner near the box allows it to read system information such as model numbers, serial numbers, processor speed, hard disk drive size and memory, as well as any end-user information you choose to record.

When used in conjunction with a compatible radio-frequency security system, Asset ID can be used to assist security personnel in preventing unauthorized removal of PCs. Using this radio-frequency identification system, Asset ID detects the movement of the PC. If movement is not authorized, the system disables the PC.

Handheld scanners and other scanning devices must be purchased separately from Asset ID Partners, third-party companies who have worked closely with IBM to ensure the compatibility of this technology with industry standards. A listing of Asset ID partners is available at www.ibm.com/pc/us/desktop/assetid.

IBM Alert On LAN

Alert On LAN instrumentation allows the Ethernet to be configured to send chassis intrusion, LANboot tamper, presence heartbeat, and environmental alerts even while the machine is in a soft off state. The instrumentation allows the alerts to be enabled and configured remotely and enables operating system lockup detection and other alerts to be received through system management packages, such as LANDesk Workgroup Manager and IBM NetFinity Manager.

A PC equipped with Alert on LAN acts as its own security guard. When someone unplugs the system from its power supply or network, an alert is instantly generated to a network administrator, to building

36 Technical Information Manual

Chapter 6. IBM System Management Tools

security, or to whomever you designate. When paired with an IBM Netfinity server or Intel LANDesk server products, Alert on LAN can send a message to your pager.

Alert on LAN sends either status or alert packets to your management server. Even after the system is powered off, Alert on LAN-enabled PCs draw a trickle charge that allows generation and transmission of packets via the integrated 10/100 Ethernet controller.

Alert on LAN leverages existing industry-standard technologies, such as the Desktop Management Interface (DMI) and Wake on LAN to provide security for your client PCs, even when they have been powered off.

Protect your assets

Alert on LAN protects your computer assets at the time they are most vulnerable: after they have been powered off. An Alert on LAN-enabled PC is always on guard.

Alert on LAN sends a status packet at regular intervals regardless of the power state of the client system. If the system is disconnected from its power source or network, the management server will detect the loss of packets and trigger a warning alert.

Alert on LAN monitors the chassis intrusion feature of DMI-compliant management chips. Even if the PC has been powered off, Alert on LAN will issue an alert notification whenever a system chassis is opened.

Alert on LAN can notify you if the processor has been removed from a client system.

Reduce response times

Alert on LAN can monitor each system in your network as it powers up, and notify you of configuration changes, hard drive failures, or other POST errors.

Alert on LAN can also notify you when a client operating system fails to load or crashes during routine operations. You can respond without waiting for the user to file a complaint, helping to ensure that their productivity is maintained.

Alert on LAN monitors the system variables measured by a DMI-compliant manageability chip-temperature, fan speed, voltage and chassis intrusion. Whenever any of these variables fall outside of the recommended parameters, Alert on LAN can generate an alert.

Customized responses

You can determine how Alert on LAN reacts to each scenario described above. When you know that systems are being serviced or retired, you can simply remotely disable the client from the management server so no alerts are generated when it is unplugged or its chassis is opened.

You can program Alert on LAN to notify network administrators or building security that a system is being tampered with or removed. You can have your management server dial a pager and deliver a numeric or alphanumeric message that enables you to respond to a problem when you are in a different location.

You can determine how sensitive Alert on LAN is to day-to-day problems.

IBM SMART Reaction Client

This application is designed to protect data on computers that have Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) hard disk drives. S.M.A.R.T. monitors the status of a hard disk drive and generates predictive failure analysis (PFA) alerts if a potential failure exists within the drive. IBM SMART Reaction Client intercepts these alerts and converts them to useful responses (such as displaying screen messages at the client workstation or alerting additional parties that a specific workstation has a potential hard disk failure).

Chapter 6. IBM System Management Tools 37

Chapter 6. IBM System Management Tools

IBM SMART Reaction Client has a full-function backup and restoration program, as well as a mirroring program, which can be used to dynamically "mirror" the contents of up to 64 folders to another hard disk. As source files are saved, the mirror files are automatically updated to contain the same data.

IBM SMART Reaction Client also has a built-in scheduler for scheduling backup, restore, and mirror operations. The IBM SMART Reaction Manager program must be installed and running on at least one network computer before IBM SMART Reaction Client can be installed on any client workstation. IBM SMART Reaction Manager, as well as complete documentation on the IBM SMART Reaction program (Client and Manager), is available at http://www.pc.ibm.com/us/desktop/sr on the World Wide Web.

In the SMART Reaction environment, the Client system is constantly monitoring the Hard Disk for potential problems. This is done by using the SMART technologies included in the Hard Disk to periodically monitor the disk using a technique known as Predictive Failure Analysis. If the Hard Disk begins to have a high number of retries when reading or writing data, a SMART Alert is passed to the DMI Instrumentation Code running on the Client System. This Alert is then passed to SMART Reaction Client application, which will automatically react to the potential failure based on Administrator defined policies.

SMART Reaction

IBM SMART Reaction automatically backs up data from S.M.A.R.T. hard disk drives that predict an imminent failure. In addition to data backup, SMART Reaction can trigger a rich set of customizable responses, including e-mail or pager notification to your technical support staff.

SMART Reaction also allows you to protect your most critical client data directories by having them constantly "mirrored" on a server- when data in these directories changes, an identical copy is automatically stored on the server.

SMART Reaction can help save time and money by allowing remote and unattended system backups and data restoration.

SMART Reaction can be used as a stand-alone application, but it also integrates seamlessly into many of the most popular backup applications, providing enhanced functionality at no additional expense.

Preparing for data disasters: Despite hard disk drive manufacturers' efforts to produce hard disk drives that won't fail, occasionally they do. And when they do, it can be a catastrophe for your business.

That's why leading hard disk drive manufacturers created an industry standard for hard disk drives called Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) S.M.A.R.T. drives are designed to monitor specific parameters of their own performance, such as the rate of read-write errors, and issue an alert when these parameters indicate a potential problem. (Approximately 60% of hard disk failures are predictable.) The alert can be sent to the user and/or a network administrator, who can then back up the data on the drive and request a timely repair.

IBM SMART Reaction software goes an important step further by responding to a S.M.A.R.T. drive alert automatically, even if the system and network are unattended. Upon receiving a S.M.A.R.T. alert, SMART Reaction software can immediately start backing up the disk's data to a server or other data device of your choice. SMART Reaction can also be programmed to initiate a response that will help ensure timely repair of the faulty drive, from e-mailing a network administrator to paging a technician.

Chapter 6. IBM System Management Tools

IBM SMART Reaction

IBM SMART Reaction adds an important new tool to IBM's comprehensive suite of asset protection solutions, which provide customers with system security and data protection capabilities that help protect technology and information assets. These enhanced capabilities help to offer the "Total Benefit of Ownership" (TBO).

IBM SMART Reaction is a client/server application that allows a network administrator to perform:

Regularly scheduled system backups (attended or unattended). Continuous or periodic backups (mirroring) of critical data files. Emergency system backups when a S.M.A.R.T. Predictive Failure alert is issued.

SMART Reaction builds upon and complements the full range of systems management features found in IBM commercial PCs, including Wake on LAN, LANClient Control Manager (LCCM), DMI BIOS, Instrumentation Code and S.M.A.R.T. hard disk drives.

The SMART Reaction application consists of two components:

1. The SMART Reaction Manager, which resides on a Windows NT 4.0 system (either a server or a workstation), and

2. The SMART Reaction Client, which resides on the client system and supports either Windows 95 or Windows NT 4.0 Workstation.

In the SMART Reaction environment, S.M.A.R.T. technologies included in each client hard disk drive monitor the disk periodically using a technique known as Predictive Failure Analysis (PFA). If the hard disk drive begins to experience a high number of retries when reading or writing data, a S.M.A.R.T. Alert is passed to the DMI Instrumentation Code running on the client system. This alert is then passed to the SMART Reaction Client application, which will automatically respond to the potential failure based on administrator-defined policies.

How SMART Reaction responds to a potential problem

Once SMART Reaction on the client system receives a S.M.A.R.T. alert, it can respond in several ways as defined by the network administrator:

1. Notification The first response is to notify the user and/or selected support personnel and administrators that there

is a potential problem with the client system hard disk drive. The user can be notified with a pop-up message that can be customized to include information such as detailed instructions, telephone numbers, etc. SMART Reaction can also send an e-mail notification of the problem to appropriate persons at local or remote addresses. Finally, SMART Reaction can also be programmed to issue a pager notification if the server has telephony support.

2. Data backup with legacy tools To help protect your critical data, the SMART Reaction Manager can automatically begin a backup

process using your network's legacy backup software. SMART Reaction is compatible with many of the industry-leading backup programs from manufacturers such as Seagate, Cheyenne, ADSM, etc.) This capability helps ensure that IBM PCs that support SMART Reaction technology can be integrated seamlessly into your existing network. SMART Reaction will simply pass the backup command to your backup software for processing via your normal procedures.

3. Backup with SMART Reaction SMART Reaction also includes its own set of robust backup capabilities that enable it to protect your

data without relying on other backup software. A DMI alert passed to the SMART Reaction Manager

Chapter 6. IBM System Management Tools 39

Chapter 6. IBM System Management Tools

includes information such as drive size, partitioning, file format and current capacity. This enables SMART Reaction Manager to allocate the necessary space on the administrator-defined backup file server. Once the space is allocated, SMART Reaction Client transfers all of the data on the client hard disk to the server.

4. Continuous data mirroring Aside from the initial S.M.A.R.T. alert notification, SMART Reaction can be configured such that the

user does not need to take any action to continue working and remain productive. That's because SMART Reaction will automatically copy any new data they save to the selected file server. In essence, there will be a "mirror-image" of their hard drive maintained on the server until such time as their local drive is repaired. Network administrators can program the frequency of the data mirroring to provide this functionality without compromising system performance needlessly.

SMART Reaction Restore process

Now that the user's data is protected, SMART Reaction's innovative functionality continues to provide assistance to the technician or administrator responsible for repairing the client system.

First, someone must physically install a new hard disk drive into the client's system. Then, critical software and the backed-up data must be re-installed on the system. Without SMART Reaction, the network administrator would have to sit at the client's system and install the operating system, drivers and applications and then copy the backed-up data from a remote server. With SMART Reaction, this software and data restoration can be performed remotely and unattended.

To get the user back on-line, the network administrator can simply invoke the SMART Reaction server application and schedule a convenient time to Restore the failed client. Working in tandem with IBM Wake On LAN technology and LANClient Control Manager (LCCM) software, the Restore operation can take place at any time, even after the system has been powered off. SMART Reaction can automatically restore the user's system to its original state, including the data present at the time of the S.M.A.R.T. Alert as well as any data generated while waiting for the replacement hard disk drive.

Critical data mirroring

SMART Reaction can also help you protect your most critical data all of the time, not just when a hard disk drive issues a Predictive Failure alert. The software's data-mirroring capabilities can be used full-time to create continually refreshed copies of selected data on a file server.

This redundant storage helps ensure that any critical data is available in two places-on the client and on a server. Such data is protected even if the client system is stolen or experiences an unpredictable failure.

Obviously, due to server space and network traffic constraints, you may not want to constantly mirror data from every client — you can select only the data that is most important to your business. But SMART Reaction is capable of mirroring up to 64 client directories, including their subdirectories, at a time. And you can program how often data is mirrored to achieve an optimum balance of data protection and system performance.

Intel LANDesk Client Manager

The LANDesk Client Manager is a DMI compliant management application that supplies a user-friendly DMI management interface and component instrumentation. This application provides self-help tools, including a PC health meter, local alerting of potential problems, and hardware inventories. It automatically polls hardware to detect failure conditions and proactively alerts the user of potential problems. When the computer is connected to a network with LANDesk Workgroup Manager, hardware information and alerts can be retrieved across the network.

Advanced Configuration and Power Interfaces (ACPI)

Advanced Configuration and Power Interfaces (ACPI) will provide a standard means to integrate power management features throughout a system, including hardware, operating systems, and application software. With such integration and power management, the system can automatically turn off and on peripherals such as CD-ROMs, network cards, hard disk drives and printers as well as consumer devices connected to the PC, including VCRs, TVs, phones, and stereos. ACPI technology will also enable peripherals to activate and deactivate the PC. Other ACPI specification points of emphasis include the following:

ACPI specifies a register-level interface to core power management functions and a descriptive

interface for additional hardware features.

ACPI provides a generic system event mechanism for Plug and Play, in addition to an operating

system-independent interface for configuration control.

ACPI leverages Plug and Play BIOS data structures while providing a processor architecture

independent implementation-compatible with both Windows 95 and Windows NT.

ACPI represents the foundation of the Microsoft OnNow initiative. OnNow represents a system-wide approach to system and device power control. OnNow is a term for a PC that is always on but appears off and responds to user or other requests.

Wake on LAN

Enhances remote management by enabling file updating and asset tracking on powered-off computers.

Permits remote system setup, updates and asset tracking to occur after hours and on weekends so daily LAN traffic is kept to a minimum and users are not interrupted.

Helps increase productivity of LAN administrators and computer users.

Available on all current IBM IntelliStation and Client System PC and ThinkPad models.

Wake on LAN is a technology that enables you to remotely manage the clients in your network even if they have been turned off. With the need to provide consistent and timely updates, such a feature brings new levels of control, simplicity and savings to LAN-based networks.

IBM Client System PCs, IntelliStations, and ThinkPads offer many features designed to help reduce your total cost of doing business. Working with Intel through the AMA, IBM has devised a number of ways to integrate system management software with intelligent hardware. Wake on LAN, LANClient Control Manager (LCCM), IBM Netfinity Manager and Intel LANDesk Client Manager are system management tools that work together to attack your computing costs by allowing you to automate time-consuming, tedious PC management tasks and schedule these tasks for a time that is the least disruptive to users. Wake on LAN turns on the networked computers, and then your choice of these network management tools handles remote management operations and asset tracking. As long as the computers in the network are Wake on LAN-enabled and electricity is available, Wake on LAN can turn on any or all of the

Chapter 6. IBM System Management Tools 41

PCs in your network so that LCCM, IBM Netfinity Manager or LANDesk can perform the management tasks you've defined.

Wake on LAN components

Wake on LAN requires the following components:

A Wake on LAN-enabled Token-Ring or Ethernet LAN adapter card

These adapters are either preinstalled, integrated on the system board, or can be installed on current IBM IntelliStations, Client System PCs ThinkPad docking stations. Support for both Token-Ring and Ethernet gives you a choice of network types, while allowing you to change from one type to the other by simply changing adapter cards.

A client with Wake on LAN capability built in

In IBM IntelliStations and Client System PCs that have a Wake on LAN-enabled LAN adapter card integrated or installed, the LAN adapter interfaces are as follows.

– Network interface to decode the wake-up frame. This is how the LAN adapter determines whether

the wake-up frame is addressed to the client.

– Auxiliary power interface for auxiliary adapter power source. A wire runs from the client's power

supply to the adapter card. This wire supplies 5 volts of power, which the adapter card needs to turn on the client. Power is available while the client is plugged into an electrical outlet that is receiving power.

– Wake-up signal interface. The adapter uses this interface to notify the client that it has received a

wake-up frame.

– System bus interface. This interface is for reading and writing control information that is specific to

the wake-up function.

Chapter 6. IBM System Management Tools

Software to trigger the wake-up frame

Remote network management software is required to send a special wake-up frame to the Wake on LAN-enabled LAN adapter.

How Wake on LAN works

The following sequence of events occurs when Wake on LAN turns on a client:

1. Remote network management software, such as LANClient Control Manager or IBM Netfinity Manager, sends a wake-up frame to the client. The wake-up frame is based on industry-standard Magic Packet specifications. See "Definition of the Wake-up Frame" for a description of the wake-up frame's contents.

2. The Wake on LAN-enabled adapter in the client receives the wake-up frame and analyzes it to determine whether the frame contains the client's media access control (MAC) address.

3. If the frame contains the client's MAC address and if CMOS is enabled, the client turns on, just as if you turned it on using the On/Off switch.

4. The remote network management software performs the tasks that it has been programmed to perform.

Definition of the Wake-up Frame

The wake-up frame contains a unique data field not normally expected in typical traffic on a LAN. When a Wake on LAN-enabled adapter on a turned-off client decodes this data field, a wake-up signal is generated. This wake-up signal causes the client to power on.

The key to the wake-up frame is the MAC address of the target client, which is repeated 16 times. This

42 Technical Information Manual

Chapter 6. IBM System Management Tools

pattern of 16 addresses in the data field is not expected to occur in any normal LAN frame other than the specific wake-up frame.

The destination address can be either a specific address or a broadcast address. If the destination address is a specific address, the wake-up frame is sent only to the client at that address. However, since the client is powered off and no longer transmitting, some protocols remove this client's MAC address from routing tables and internal caches at other nodes. In this case, wake-up frames addressed directly to the target client are discarded because nodes and routers do not know where to send them.

The solution to this problem is to use a broadcast address. A directed broadcast has a valid network address and a broadcast host address. Network routers and nodes forward directed broadcasts to the appropriate network, where it is seen as a MAC-level broadcast and detected by the powered off client.

Give your IntelliStations and Client System PCs a wake-up call

IBM is committed to providing you highly manageable computers so your company can reclaim excessive resources applied to IT management. Central to this commitment is the AMA-working together to integrate system management software with intelligent hardware, IBM and Intel have made Wake on LAN an industry standard that's changing the way companies manage their PCs. The alliance is already yielding dividends for customers, with the incorporation of IBM Wake on LAN functionality into Intel's 10/100 and 10BaseT Ethernet adapters and LANDesk software. The remote setup and management capabilities of IBM IntelliStations, Client System PCs and ThinkPads mean you can greatly reduce the need for technicians to visit individual systems to perform management tasks, keeping your IS group and the users they support more productive.

IBM LANClient Control Manager version 2.0 (LCCM)

IBM LANClient Control Manager (LCCM) version 2.0 is a server-based application that simplifies the

setup, configuration, rollout and ongoing lower-level management of networked IBM PCs.

LCCM incorporates a "push" rather than a "pull" approach, so that network administrators can gain control of a client over a network to perform tasks that would normally require their physical presence at the system. It can significantly reduce the costs of deploying and maintaining IBM clients by reducing the number of visits to each machine.

LCCM is a preboot application, which allows administrators to remotely update a system's BIOS, change CMOS settings, execute commands such as FDISK or FORMAT, or install a new operating system.

LCCM v2.0 adds support for clients using the industry-standard DHCP/PXE protocol, which allows identification of specific systems over one or more routers. LCCM continues to support the Remote Program Load (RPL) protocol as an alternative management preboot agent.

LCCM v2.0 can retrieve client information recorded using an Asset ID-compatible device.1 You can use Asset ID to indicate the necessary software image for end users, before the system is even unpacked. Later, after the system is plugged in, LCCM can deliver the correct software automatically.

LCCM is licensed for use at no additional charge for IBM client systems, including current models of the PC 300 and IntelliStation families and the ThinkPad 770. It is available for downloading from the Web at www.ibm.com/pc/us/desktop/lccm.

LCCM v2.0 is a server-based software tool that enables remote and unattended configuration, deployment, redeployment and ongoing lower-level management of IBM PCs. Since LCCM gains control of a PC before it boots its local operating system, many of the lower-level tasks that previously required a visit to each client can now be performed over the network. Using LCCM, a network administrator can:

Remotely identify a client and gather important vital product data such as serial number, machine type model, system memory, hard disk drive capacity and BIOS level.

Capture information about end users and their software requirements that has been entered through the use of a

Chapter 6. IBM System Management Tools 43

Chapter 6. IBM System Management Tools

handheld Asset ID unit.

Prompt users (if present) for specific information about their name, department, location, etc. and

capture this information into the client hardware information.

Export captured client information to other tools for inclusion in higher level, workgroup and

enterprise-wide systems management offerings.

Remotely install via image copy or unattended installation an operating environment such as Windows

95 or Windows NT(r).

Schedule client configurations or updates to occur once or periodically. Manage hundreds of clients from a single server and configure up to 32 simultaneously (assuming

available bandwidth).

Modify a system's CMOS settings (e.g., change boot sequences, enable/disable onboard components,

restore passwords, etc.)

Update or flash a system's BIOS (e.g., use a newer or older level of BIOS for enterprise-wide

consistency or change the BIOS to match the local language).

Assign or change the administrator password on one or more client workstations to protect the BIOS

settings against unauthorized end-user changes.

Power-on client systems by sending a Magic Packet to specific Wake on LAN-enabled systems or

docking stations.

Schedule events to take place unattended on a specific date and at a specified time as a onetime event, or on a recurring basis (e.g., to execute complete or partial system backups and virus scans, or simply to power-on a client at specific intervals).

When combined with the other robust management features of IBM PCs, such as Wake on LAN, LCCM helps make system deployment and configuration as simple as plug-in-and-go. Once the systems are plugged into a power supply and network, the rest of the client setup can be performed remotely from a network console. Using LCCM, you can schedule a convenient time to power the systems up, flash their BIOS to ensure consistency across your organization, download the appropriate software image for each user, and then power the systems down.

LCCM is also useful throughout a system's life cycle for performing preboot management functions, such as formatting a hard disk drive over a network. This software complements popular postboot client management software tools such as Tivoli TME 10, Microsoft's System Management Server, Intel LANDesk Client Manager, and Computer Associates' TNG Unicenter.

LCCM is made possible, in part, by the IBM/Intel Advanced Manageability Alliance (AMA). The AMA builds on industry-standard technology to create new, more effective solutions for customers, such as Wake on LAN. LCCM v2.0 is industry-standard-based, incorporating support for DHCP and the Preboot eXecution Environment (PXE) defined in the 1997 NetPC Guideline and preliminary Lean Client specifications, as well as the Remote Program Load (RPL) boot protocol used by the industry since 1986.

LCCM works with IBM systems shipped as early as February 1996 that are equipped with a supported IBM Token-Ring or Ethernet Wake on LAN network interface adapter. These include models from the current PC 300 and IntelliStation families, as well as the PC 730, 750, 330, 350 and 365 series.2 The benefits of LCCM have also recently been extended into mobile computing with support for the IBM ThinkPad 770 equipped with the optional SelectaDock III.

System deployment

LCCM can significantly reduce the time and resources required to deploy or redeploy IBM PCs, especially when installation of a custom software image is needed.

First, LCCM needs to gain control of the client. This can occur automatically the first time the user powers the system on, or the network administrator can power the system remotely using Wake on LAN. LCCM can generate the Magic Packet(s) needed to power

44 Technical Information Manual

Chapter 6. IBM System Management Tools

one or more PCs over the network. The Magic Packet identifies each specific PC through the unique MAC address assigned to every network interface device.

LCCM can broadcast a Magic Packet on local area networks made up of hubs, bridges, and switches. LCCM can also wake a client on the other side of a router if the administrator includes the subnet address of the router. LCCM wraps the subnet address with the Magic Packet so that it can travel across router(s) to the local domain where the client resides before the packet is broadcast on the LAN.

As the IBM PC powers on for the first time on the network, it will query the network before booting from its local hard disk drive. LCCM's Scan (discovery) feature will recognize that a new system has been added to the network and respond with a signal that allows the network to gain control of the client and prevents the local operating system from loading.

LCCM will then query the client for vital product data through its Systems Management BIOS and Wired for Management/DMI features. LCCM creates a client profile as part of an Individual Client Details record and database with this information (e.g., machine type and serial number, disk, memory size, graphics/video chipset, MAC address, BIOS level and more.)

If the PC is equipped with Asset ID, as are select models of IBM client system PCs and IntelliStations, LCCM can also recover any information that has been recorded about the user. Asset ID allows an administrator using a radio-frequency handheld unit to record information to a system EEPROM without even opening the system's packing carton.

Otherwise, LCCM assigns a default name to the client during the scan, and can optionally prompt the end user to enter personal information such as his location, department and phone number, etc. If a user is not present, this request will automatically time-out. The data collected is entered automatically into the Individual Client Details record.

Flashing the CMOS or BIOS

The LCCM administrator can use the information gathered from the client to review its CMOS settings and BIOS level. In some cases, these may need to be changed to ensure consistency across the enterprise or to conform to corporate policies.

Since LCCM gains control of the system before the local operating system was booted, LCCM allows administrators to remotely perform low-level maintenance tasks, like flashing the BIOS, that need to occur during the preboot state. The only alternatives are to involve the end user or send a technician to each client. LCCM is complementary to postboot management tools, which need a local operating system running, such as DMI browsers or software change management programs.

Installing software

Next, the network administrator uses the information that LCCM has gathered about the client to determine the end user's software requirements, including operating system and applications. (When Asset ID is used, this step can be simplified by recording the end user's software profile to the system EEPROM.)

The software can come from one of two sources: a compressed software "image" that includes a copy of all of the software needed by the local client, or from installation files located on a file server. In either case, the software can be downloaded to the client without intervention by the user or the administrator.

6. LCCM acknowledges PC and tells system to reboot locally-DONE

Perhaps the most convenient feature of LCCM is a scheduling feature that allows an administrator to perform the above tasks at the most convenient time, when they will have the least impact on user productivity and network traffic. When used with Wake on LAN, LCCM can perform its routine even if the client was initially in a powered-off state.

Chapter 6. IBM System Management Tools

Low-level management

LCCM operates by establishing LAN communications between the IBM client and the managing server before loading its operating system from a local hard disk drive. In this way, low-level maintenance tasks like formatting a hard drive, changing the BIOS, or reinstalling an operating system, can be performed without end-user involvement, even if the client operating system is unable to boot. Using LCCM, routines like FORMAT and FDISK can now be performed over a network, eliminating the need for an administrator or technician to visit the client.

LCCM's scheduling feature helps to ensure that low-level management tasks do not interfere with user productivity, because they can be performed at a time when both users and network support staff are home asleep.

LCCM v2.0 enhancements over LCCM v1.

LCCM v1.X used remote program load (RPL), a non-routable protocol, while LCCM v2.0 uses DHCP and Preboot eXecution Environment (PXE) extension, which is a routable protocol. The protocol was changed for v2.0 because many customers have routers on the same floor as well as throughout their organization, so RPL restricted the usefulness of LCCM.

The RPL process also required LCCM to have a list of supported network adapters and a range of their MAC addresses in a network.lst file and their associated device drivers, which were downloaded to the client to be managed along with the Universal Configuration Agent (UCA). LCCM v2.0 does not have this restriction because it supplies the Universal Network Device Interface (UNDI) services needed by the network interface card generating the DHCP/PXE frame.

Because of the change from RPL to DHCP, LCCM v2.0 needs to be installed on a Windows NT Server configured with DHCP services. This means v2.0 is a replacement for v1.X and not a simple upgrade. Client Profile information from v1.X must be saved and then restored to v2.0.

Before LCCM, users or network support personnel needed to be physically present at each client to perform tasks such as installing a custom software configuration or reformatting a hard drive. By incorporating a "push" instead of a "pull" approach, a network administrator can perform these time-consuming tasks remotely. When combined with other advanced manageability features such as Wake on LAN and Asset ID, LCCM makes setting up IBM PCs much easier.

Chapter 7. System Compatibility

This chapter discusses some of the hardware, software, and BIOS compatibility issues for the computer. Refer to &comp. for a list of compatible hardware and software options.

Hardware Compatibility

This section discusses hardware, software, and BIOS compatibility issues that must be considered when designing application programs.

Many of the interfaces are the same as those used by the IBM Personal Computer AT. In most cases, the command and status organization of these interfaces is maintained.

The functional interfaces are compatible with the following interfaces:

Intel 8259 interrupt controllers (edge-triggered mode) National Semiconductor NS16450 and NS16550A serial communication controllers Motorola MC146818 Time of Day Clock command and status (CMOS reorganized) Intel 8254 timer, driven from a 1.193 MHz clock (channels 0, 1, and 2) Intel 8237 DMA controller, except for the Command and Request registers and the Rotate and Mask

functions; the Mode register is partially supported

Intel 8272 or 82077 diskette drive controllers Intel 8042 keyboard controller at addresses hex 0060 and hex 0064 All video standards using VGA, EGA, CGA, MDA, and Hercules modes Parallel printer ports (Parallel 1, Parallel 2, and Parallel 3) in compatibility mode

Use the above information to develop application programs. Whenever possible, use the BIOS as an interface to hardware to provide maximum compatibility and portability of applications among systems.

Chapter 7. System Compatibility

Hardware Interrupts

Hardware interrupts are level sensitive for PCI interrupts and edge sensitive for ISA interrupts. The interrupt controller clears its in-service register bit when the interrupt routine sends an End-of-Interrupt (EOI) command to the controller. The EOI command is sent regardless of whether the incoming interrupt request to the controller is active or inactive.

The interrupt-in-progress latch is readable at an I/O-address bit position. This latch is read during the interrupt service routine and might be reset by the read operation or it might require an explicit reset.

Note: For performance and latency considerations, designers might want to limit the number of devices

sharing an interrupt level.

With level-sensitive interrupts, the interrupt controller requires that the interrupt request be inactive at the time the EOI command is sent; otherwise, a new interrupt request will be detected. To avoid this, a level-sensitive interrupt handler must clear the interrupt condition (usually by a read or write operation to an I/O port on the device causing the interrupt). After processing the interrupt, the interrupt handler:

1. Clears the interrupt

2. Waits one I/O delay

3. Sends the EOI

4. Waits one I/O delay

5. Enables the interrupt through the Set Interrupt Enable Flag command

Hardware interrupt IRQ9 is defined as the replacement interrupt level for the cascade level IRQ2. Program interrupt sharing is implemented on IRQ2, interrupt hex 0A. The following processing occurs to maintain compatibility with the IRQ2 used by IBM Personal Computer products:

1. A device drives the interrupt request active on IRQ2 of the channel.

2. This interrupt request is mapped in hardware to IRQ9 input on the second interrupt controller.

3. When the interrupt occurs, the system microprocessor passes control to the IRQ9 (interrupt hex 71) interrupt handler.

4. This interrupt handler performs an EOI command to the second interrupt controller and passes control to the IRQ2 (interrupt hex 0A) interrupt handler.

5. This IRQ2 interrupt handler, when handling the interrupt, causes the device to reset the interrupt request before performing an EOI command to the master interrupt controller that finishes servicing the IRQ2 request.

Notes:

RWF — —

1. Do not use either a 250/500 KB or 300/500 KB diskette drive for 5.25-inch diskettes that are designed for the 1.2MB mode.

2. Low-density 5.25-inch diskettes that are written to or formatted by a high-capacity 1.2 MB diskette drive can be reliably read only by another 1.2 MB diskette drive.

Copy Protection

The following methods of copy protection might not work in systems using the 3.5-inch 1.44 MB diskette drive.

Bypassing BIOS routines

– Data transfer rate: BIOS selects the proper data transfer rate for the media being used. – Diskette parameter table: Copy protection, which creates its own diskette parameter table, might

not work in these drives.

Diskette drive controls

– Rotational speed: The time between two events in a diskette drive is a function of the controller. – Access time: Diskette BIOS routines must set the track-to-track access time for the different types

of media that are used in the drives.

– ‘Diskette change’ signal: Copy protection might not be able to reset this signal.

Write-current control: Copy protection that uses write-current control does not work, because the

controller selects the proper write current for the media that is being used.

Chapter 7. System Compatibility

Hard Disk Drives and Controller

Reading from and writing to the hard disk is initiated in the same way as in IBM Personal Computer products; however, new functions are supported.

Software Compatibility

To maintain software compatibility, the interrupt polling mechanism that is used by IBM Personal Computer products is retained. Software that interfaces with the reset port for the IBM Personal Computer positive-edge interrupt sharing (hex address 02Fx or 06Fx, where x is the interrupt level) does not create interference.

Software Interrupts

With the advent of software interrupt sharing, software interrupt routines must daisy chain interrupts. Each routine must check the function value, and if it is not in the range of function calls for that routine, it must transfer control to the next routine in the chain. Because software interrupts are initially pointed to address 0:0 before daisy chaining, check for this case. If the next routine is pointed to address 0:0 and the function call is out of range, the appropriate action is to set the carry flag and do a RET 2 to indicate an error condition.

Machine-Sensitive Programs

Programs can select machine-specific features, but they must first identify the machine and model type. IBM has defined methods for uniquely determining the specific machine type. The machine model byte can be found through Interrupt 15H, Return System Configuration Parameters function (AH)=C0H).
