System Board

1.1 Features

The M9LD is a dual-processor system board built on an ATX baseboard that supports the Intel Pentium II CPU processor running at 266/66 MHz, 300/66 MHz, 333/66 MHz, 350/100 MHz, 400/100 MHz, and future Intel Pentium II processors. It contains an exclusive connector for the CPU board that carries two slots for the Pentium II CPU modules.

The host bus interface supports a Pentium II processor with 66 or 100 MHz bus frequency. It also supports synchronous DRAM (SDRAM) DIMMs.

The M9LD supports PCI IDE, universal serial bus (USB) host/hub, and enhanced power management. It also supports Ultra DMA/33 synchronous DMA-compatible devices.

A 50-pin Fast SCSI (Small Computer System Interface) and a 68-pin Wide SCSI comes with the M9LD to connect SCSI devices. Wide SCSI supports 16-bit transfers while fast SCSI uses a 8-bit bus that doubles the clock rate to support data rates of 20 Mb/s.

The M9LD system board also supports the USB (Universal Serial Bus) connector, and other standard features such as two UART NS16C550 serial ports, one parallel port with Enhanced Parallel Port (EPP)/Extended Capabilities Port (ECP) features, a diskette drive interface, and two embedded hard disk interfaces. The board also includes a built-in 10/100 Mb/s Intel 82557 LAN chip.

System Board 1-1

The system board supports two optional features, ASM Pro and the remote diagnostic management (RDM), that allow better server management. ASM Pro detects problems in CPU thermal condition, CPU working voltage detection (±12V/±5V/3.3V/1.5V), and PCI bus utilization calculation. It also detects if the CPU fan or the chassis fan malfunctions. RDM allows execution of the RDM diagnostic program from a remote RDM station to fix detected problems or to reboot the system.

This system is fully compatible with MS-DOS V6.X, DOS/V, IBM OS/2 Warp, Novell Netware, Novel SFT III, SCO UNIX, and Windows NT.

1.7 Installing Expansion Cards

1.7.1 Installing a PCI Card

To install PCI cards:

1. Locate the PCI slot(s) on the mainboard.

2. Remove the bracket on the housing opposite to the empty PCI slot.

3. Insert a PCI card into the slot. Make sure that the card is properly seated.

4. Secure the card to the housing with a screw.

When you turn on the system, BIOS automatically detects and assigns resources to the PCI devices.

Figure 1-4 Installing a PCI Card

System Board 1-13

1.7.2 Installing an ISA Card

Both PnP and non-PnP ISA cards require specific IRQs. When installing ISA cards, make sure that the IRQs required by these cards are not previously assigned to PCI devices to avoid resource conflicts.

Follow these steps when installing ISA cards:

1. Remove all PnP cards installed in the system, if any.

2. Install non-PnP ISA cards.

3. Turn on the system.

4. Use Windows 95 or ICU to manually assign the appropriate IRQs to the cards. This ensures that BIOS will not use the resources assigned to the non-PnP ISA cards.

BIOS detects and configures only PnP cards.

5. Turn off the system.

6. Locate the expansion slots and install the PnP ISA and PCI cards.

7. Turn on the system. This time PnP BIOS automatically configures the PnP ISA and PCI cards with the available resources.

1.8 ASM Pro

ASM Pro is a server management tool based on the Simple Network Management Protocol (SNMP). It detects server problems related to the CPU thermal condition, 5V/3.3V/1.5V detection, or PCI bus utilization calculation.

This feature is designed primarily for server supervisors and management information system (MIS) personnel to help them detect errors or potential trouble spots in their network servers through a single management station.

ASM Pro consists of two major parts:

• ASM-Station - a Windows-based monitoring station that

communicates with the ASM-Agents.

• ASM-Agent(s) - the individual servers managed by the

ASM-Station.

Refer to the ASM Pro user’s manual for more information.

1-16 User’s Guide

1.9 Remote Diagnostic Management

Remote Diagnostic Management (RDM) is a network management tool that utilizes modems and telephone lines to control a host of servers from a remote station. It monitors and analyzes the server condition, updates the BIOS settings if necessary, or reboots the server in the event of failure and quickly returns it to normal operation. This capability to execute the RDM program from a remote site bridges the distance barrier in fixing server problems and reduces wasted time due to system failure.

1.9.1 Installing an RDM Module

The system board comes with connectors CN6 and CN7 to accommodate the RDM module.

Follow these steps to install the RDM module and connect the cable:

1. See Figure 1-2 for the location of the RDM connectors.

2. Gently insert the RDM module into CN6 and CN7. The module fits only in one direction. Do not force it into to the connectors.

1.10 Error Messages

Do not continue using the computer if you receive an error message of any type. Note the message and take corrective action. This section explains the different types of error messages and corresponding corrective measures.

There are two general types of error messages:

• Software

• System

1.10.1 Software Error Messages

Software error messages are returned by your operating system or application. These messages typically occur after you boot the operating system or when you run your applications. If you receive this type of message, consult your application or operating system manual for help.

1.10.2 System Error Messages

A system error message indicates a problem with the computer itself. A message of this type normally appears during the power-on selftest, before the operating system prompt appears.

1.10.3 Correcting Error Conditions

As a general rule, if an error message says "Press F1 to continue," it is caused by a configuration problem, which can be easily corrected. An equipment malfunction is more likely to cause a fatal error, i.e., an error that causes complete system failure.

Here are some corrective measures for error conditions:

1. Run Setup. You must know the correct configuration values for your system before you enter Setup, which is why you should write them down when the system is correctly configured. An incorrect configuration is a major cause of power-on error messages, especially for a new system.

2. Remove the system unit cover. Check that the jumpers on the system board and any expansion boards are set correctly.

3. If you cannot access a new disk, it may be because your disk is not properly formatted. Format the disk first using the FDISK and FORMAT commands.

4. Check that all connectors and boards are securely plugged in.

If you go through the corrective steps above and still receive an error message, the cause may be an equipment malfunction.

If you are sure that your configuration values are correct and your battery is in good condition, the problem may lie in a damaged or defective chip.

In either case, contact an authorized service center for assistance.

PCI IRQ Setting

This parameter allows for Auto or Manual configuration of PCI devices. If you use plug-and-play (PnP) devices, set this parameter to Auto. The system then automatically assigns IRQ to the PnP devices. If your PCI device is not a PnP, you can manually assign the interrupt for each device. Refer to your PCI card manual for more information.

When the PCI IRQ Setting is set to Auto, all the IRQ setting fields become gray and nonconfigurable.

3-30 User’s Guide

PCI SLOTS

These parameters allow you to specify the appropriate interrupt for each of the PCI devices. You can assign IRQ3, IRQ4, IRQ5, IRQ7, IRQ9, IRQ10, IRQ11, IRQ12, IRQ14, or IRQ15 to the slots.

Make sure that the interrupt you assign in any of the PCI slots are not used by other devices to avoid conflicts.

Press or to move between fields. Press or to select options.

ONBOARD LAN

This item allows you to manually assign the interrupt for the onboard LAN when the PCI IRQ Setting parameter is set to Manual . This parameter is grayed and not user-configurable when the PCI IRQ Setting is set to Auto.

ONBOARD SCSI2

This item allows you to manually assign the interrupt for the second onboard SCSI device when the PCI IRQ Setting parameter is set to

Manual . This parameter is grayed and not user-configurable when

the PCI IRQ Setting is set to Auto and when the second Onboard SCSI parameter under the Onboard Devices Configuration screen is set to Disabled .

BIOS Utility 3-31

PCI DEVICE LATENCY TIMER

This parameter allows you to set the length of time for a PCI device to use the PCI bus.

A PCI master can burst indefinitely as long as the target can source/sink the data, and no other agent requests for the bus. If another PCI device requests for the use of the PCI bus, a PCI bus arbitration takes place, and the tenure of the device currently using the PCI bus cannot go over the PCI latency time set in BIOS. This setting depends on your application. For example, if you install a high bandwidth block I/O card, e.g., FDDI, the longer the latency time the better. This setting only affects the primary PCI components (PCI slots 1, 2, 3, and onboard LAN). The secondary PCI components (PCI slots 4, 5, and onboard SCSI1 and onboard SCSI2) are always set to 20 PCI clocks.

PCI IRQ Sharing

Setting this parameter to Yes allows you to assign the same IRQ to two different devices. To disable the feature, select No.

If there are no IRQs available to assign for the remaining device function, we recommend that you enable this parameter.

VGA Palette Snoop

This parameter permits you to use the palette snooping feature if you installed more than one VGA card in the system.

3-32 User’s Guide

The VGA palette snoop function allows the control palette register (CPR) to manage and update the VGA RAM DAC (Digital Analog Converter, a color data storage) of each VGA card installed in the system. The snooping process lets the CPR send a signal to all the VGA cards so that they can update their individual RAM DACs. The signal goes through the cards continuously until all RAM DAC data has been updated and allows the display of multiple images on the screen.

Some VGA cards have required settings for this feature. Check your VGA card manual before setting this parameter.

Plug and Play OS

When this parameter is set to Yes, BIOS initializes only PnP boot devices such as SCSI cards. When set to No, BIOS initializes all PnP boot and non-boot devices such as sound cards.

Set this parameter to Yes only if your operating system is Windows 95.

Reset Resource Assignments

Set this parameter to Yes to avoid IRQ conflicts when installing non-PnP or PnP ISA cards. This clears all resource assignments and allows BIOS to reassign resources to all installed PnP devices the next time the system boots. After clearing the resource data, the parameter resets to No.

Internal Cache (CPU Cache)

This parameter enables or disables the first-level or internal memory. The default setting is Enabled.

System BIOS Cacheable

Set this parameter to Enabled if you want the system BIOS to run directly from the cache memory, thus allowing your system to function faster. Set this to Disabled to run the system BIOS from RAM. The default is Enabled.

3-34 User’s Guide

Video BIOS Cacheable

Set this parameter to Enabled if you want the video BIOS to run directly from the cache memory, thus allowing your system to function faster. Set this to Disabled to run the video BIOS from RAM. The default is Enabled.

Memory at 15MB-16MB Reserved for

To prevent memory address conflicts between the system and expansion boards, reserve this memory range for the use of either the system or an expansion board.

Memory Parity Mode

This parameter allows you to enable or disable the ECC and parity check features. Select Parity to enable the parity check feature. Select ECC to enable the ECC feature. The ECC feature enables BIOS to detect and correct data errors. Disable this parameter if you want to disregard the function.

Single Processor MP Table

Enabling this parameter allows BIOS to create a multiprocessor (MP) table.

The Windows NT system will install the multiprocessor kernel if it finds the MP table, otherwise, it will install the single processor kernel if the system can not find the MP table during installation. Enabling this option allows the system to build the multiprocessor kernel whether the system has one or two processor.

The benefit of this option is that users do not need to reinstall Windows NT to activate the MP kernel when installing a second CPU. The drawback is that it will affect the performance of the system with a single CPU running the MP kernel.

3.7.4 Non-PnP ISA Device Configuration

This parameter reserves the use of resource addresses for non-PnP ISA devices.

Whenever a parameter is set to "Yes", that address is reserved for an ISA card only. The system will not allocate this address to any PCI or PnP cards.

When set to “No”, the system will allocate these resource addresses to PCI or PnP cards.

When installing a non-PnP ISA device, you have to determine which resource address to use.
