1.3 Interface Descriptions

This section provides a more detailed explanation about the PCI Interface, the SCSI Interface, Ultra160 SCSI Technology, and LVDlink Technology.

1.3.1 The PCI Interface

PCI, a high-speed standard local bus, interfaces I/O components to the processor and memory subsystems in equipment ranging from PCs to servers. The PCI functionality for the LSIU160 is contained within the LSI53C1010. The LSI53C1010 connects directly to the PCI bus and generates signal timing and bus protocol in compliance with the PCI Speciﬁcation Revision 2.2.

44.25 pc

The PCI interface operates as a 64-bit DMA bus master capable of 64-bit addressing. The connection is made through edge connector J1, shown in Figure 2.1 on page 2-5. The signal deﬁnitions and pin numbers conform to the PCI Local Bus Speciﬁcation Revision 2.2 standard. The LSIU160 conforms to the PCI universal signaling environment for a 5 V or 3.3 V PCI bus.

1.3.2 The SCSI Interface

The SCSI functionality for the LSIU160 is contained within the LSI53C1010. This chip is a PCI to Ultra160 SCSI Controller with LVDlink Universal Transceivers. It connects directly to the SCSI bus and generates signal timing and bus protocol in compliance with SCSI standards.

The SCSI interface on the LSIU160 operates as an 8-bit or 16-bit interface. It supports 8-bit or 16-bit, synchronous and asynchronous, LVD or SE, Fast, Ultra, Ultra2, and Ultra160 SCSI protocols in various combinations. The interface is made through connectors J3 and J4 (see

Figure 2.1). Internal connector J4 is a 68-pin HD right angle latching

connector. External connector J3 is a shielded 68-pin HD right angle connector exposed in the back panel bracket. LVD/SE dual mode, active termination is provided on the LSIU160. Termination is automatically disabled when both SCSI connectors are used. The LSIU160 supplies SCSI bus TERMPWR through a blocking diode and a self-resetting 1.5 A short circuit protection device. A 40 MHz oscillator is installed on the

48.583 p

Interface Descriptions 1-5

52.5 pc

3.75 pc 10.25 pc 11.25 pc 38.25 pc

34.5 pc

LSIU160. This oscillator provides the clock frequency necessary to support Ultra160 SCSI transfers of up to 160 Mbytes/s.

1.3.3 SCSI Bus Activity LED Connector

A SCSI Bus Activity LED connector indicates the status of the SCSI bus when a LED is attached. This LED lights when the SCSI bus is transferring information.

1.4 Beneﬁts of Ultra160 SCSI

Ultra160 SCSI delivers data up to two times faster than Ultra2 SCSI. Ultra160 SCSI is an extension of the SPI-3 draft standard that allows faster synchronous SCSI data transfer rates than Ultra2 SCSI. When enabled, Ultra160 SCSI performs 80 megatransfers per second resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI. The LSI53C1010 performs 16-bit, Ultra160 SCSI synchronous data transfers as fast as 160 Mbytes/s. This advantage is most noticeable in heavily loaded systems or large block size applications

44.25 pc

such as video on-demand and image processing.

4.333 pc

The Ultra160 data transfer speed is accomplished using DT clocking. DT clocking refers to transferring data on both polarity edges of the request or acknowledge signals. Data is clocked on both rising and falling edges of the request and acknowledge signals. Double-edge clocking doubles data transfer speeds without increasing the clock rate.

1.4.1 Cyclic Redundancy Check (CRC)

Ultra160 SCSI includes CRC which offers higher levels of data reliability by ensuring complete integrity of transferred data. CRC is a 32-bit scheme, referred to as CRC-32. CRC is guaranteed to detect all single bit errors, any two bits in error, or any combination of errors within a single 32-bit range.

1.4.2 Asynchronous Information Protection (AIP)

AIP is also supported by the LSI53C1010, protecting all non-data phases, including command, status, and messages. CRC, along with AIP, provides end-to-end protection of the SCSI I/O.

1.5 Beneﬁts of LVDlink Technology

To support greater device connectivity and a longer SCSI cable, the LSIU160 features LVDlink technology, the LSI Logic implementation of Universal LVD SCSI. LVDlink transceivers provide the inherent reliability of differential SCSI, and a long-term migration path to faster SCSI transfer rates.

The LVDlink transceivers reduce the power needed to drive the SCSI bus, so that the I/O drivers can be integrated directly into the chip. LVDlink technology lowers the amplitude of noise reﬂections and allows higher transmission frequencies.

The LVDlink transceivers operate in LVD and SE modes. They also allow the chip to detect a High Voltage Differential (HVD) signal when the chip is mistakenly connected to external HVD transceivers. When connected, the LSI53C1010 automatically detects the signal type, based on the voltage detected. It automatically switches to the SE or LVD mode, as appropriate.

44.25 pc

Important: All bus devices must be LVD or SE. If a HVD device is

detected, the board puts the SCSI bus in the high impedance state and shuts down.

1.6 Beneﬁts of TolerANT®Technology

The LSI53C1010 features TolerANT technology, which includes active negation on the SCSI drivers and input signal ﬁltering on the SCSI receivers. Active negation causes the SCSI Request, Acknowledge, Data, and Parity signals to be actively driven HIGH rather than passively pulled up by terminators.

TolerANT receiver technology improves data integrity in unreliable cabling environments where other devices would be subject to data corruption. TolerANT receivers ﬁlter the SCSI bus signals to eliminate unwanted transitions, without the long signal delay associated with RC-type input ﬁlters. This improved driver and receiver technology helps eliminate double clocking of data which is the single biggest reliability issue with SCSI operations. TolerANT input signal ﬁltering is a built-in feature of the LSI53C1010 and all LSI Logic Fast SCSI, Ultra SCSI, Ultra2 SCSI, and Ultra160 SCSI devices.

Beneﬁts of LVDlink Technology 1-7

52.5 pc

3.75 pc 10.25 pc 11.25 pc 38.25 pc

34.5 pc

The beneﬁts of TolerANT technology include increased noise immunity when the signal transitions to HIGH, better performance due to balanced duty cycles, and improved fast SCSI transfer rates. In addition, TolerANT SCSI devices do not cause glitches on the SCSI bus at power-up or power-down. This protects other devices on the bus from data corruption. When it is used with the LVDlink transceivers, TolerANT technology provides excellent signal quality and data reliability in real world cabling environments. TolerANT technology is compatible with both the Alternative One and Alternative Two termination schemes proposed by the American National Standards Institute.

1.7 Benefits of SureLINK™ (Ultra160 SCSI Domain Validation)

SureLINK represents the very latest SCSI interconnect management solution. It ensures robust and low risk Ultra160 SCSI implementations by extending the Domain Validation guidelines documented in the ANSI T10 SPI-3 speciﬁcations. Domain Validation veriﬁes that the system is capable of transferring data at Ultra160 speeds, allowing it to renegotiate to lower speed and bus width if necessary. SureLINK is the

44.25 pc

software control for the manageability enhancements in the LSI53C1010. Fully integrated in the SDMS software solution, SureLINK provides Domain Validation at boot time as well as throughout system operation. SureLINK extends to the Desktop Management Interface (DMI) based System Management components of SDMS, providing the network administrator remote management capability.

4.333 pc

SureLINK Domain Validation provides three levels of integrity checking: Basic (level 1), Enhanced (level 2), and Margined (level 3). The basic check consists of an inquiry command to detect gross problems. The enhanced check sends a known data pattern using the Read and Write Buffer commands to detect additional problems. Margined check veriﬁes that the physical parameters have some degree of margin. By varying LVD drive strength and REQ/ACK timing characteristics, level 3 veriﬁes that no errors occur on the transfers. These altered signals are only used during the diagnostic check and not during normal system operation. Should errors occur with any of these checks, the system can drop back to a lower transmission speed, on a per-target basis, to ensure robust system operation.

This chapter provides instructions on how to install the LSIU160 and includes these topics:

• Section 2.1, “Quick Installation Procedure,” page 2-1

• Section 2.2, “Detailed Installation Procedure,” page 2-3

• Section 2.3, “Completing the Installation,” page 2-24

2.1 Quick Installation Procedure

This section provides an overview of the installation procedure. If you are an experienced computer user with prior host adapter installation and SCSI bus setup experience, this section may sufﬁciently describe the procedure for you. If you prefer a more detailed guidance for installing the LSIU160, proceed to Section 2.2, “Detailed Installation Procedure.”

For safe and proper installation, check the user’s manual supplied with your computer and perform the following steps.

Step 1. Ground yourself before removing this host adapter board. Step 2. Remove the LSIU160 from the packing and check that it is not

damaged. An example of this host adapter board is shown in Figure 2.1.

A more detailed drawing is located in Figure A.1. Step 3. Switch off and unplug the system. Step 4. Remove the cabinet cover on your computer to access the PCI

slots.

Caution: Ground yourself by touching a metal surface before

handling boards. Static charges on your body can damage electronic components. Handle plug-in boards by the edge;

do not touch board components or gold connector contacts.

4.333 pc

The use of a static ground strap is recommended.

Step 5. Locate the slots for installing a PCI plug-in board.

The LSIU160 requires a 32-bit or 64-bit PCI slot that allows bus

master operation. If a 32-bit PCI slot is used, bits [31:1] of the

J1 connector are inserted while bits [64:32] remain uninserted.

See Figure 2.2.

Note: For the LSIU160 to function as a 64 bit-device, it must

inserted in a 64-bit PCI slot. If the LSIU160 is inserted in a 32-bit PCI slot, it will function as a 32-bit device.

Step 6. Remove the blank bracket panel on the back of the computer

aligned with the PCI slot you intend to use.

Save the bracket screw for securing the installed board.

44.25 pc

Step 7. Carefully insert the edge connector J1 of the host adapter into

the PCI slot. Make sure the edge connector is properly aligned

before pressing the board into place. See Figure 2.2.

The bracket around connector J3 (see Figure 2.1) should ﬁt

where the blank bracket panel was removed.

Note: You may notice that the components on a PCI host adapter

face the opposite way from non-PCI adapter boards you have in your system. This orientation is correct. The board is keyed and will only go in one way.

Step 8. Secure the bracket with the bracket screw before making the

internal and external SCSI bus connections. Step 9. If you are connecting any internal SCSI devices, plug a 68-pin

connector on the end of the internal SCSI ribbon cable into

connector J2 (see Figure 2.1).

Be sure you match pin 1 on both connectors. Step 10. Connect the LED cable to J4 if desired.

This is designed to drive an off-board system LED and

indicates activity on the SCSI bus. The off-board LED will

operate at the same time as the on-board SCSI Activity LED. Step 11. Replace the cabinet cover as described in the user’s manual for

your computer.

2.2 Detailed Installation Procedure

This section provides step-by-step instructions for installing the LSIU160, and connecting it to your SCSI peripherals. If you are experienced in these tasks, you may prefer to use Section 2.1, “Quick Installation

Procedure.”

44.25 pc

2.2.1 Before You Start

Before starting, look through the following task list to get an overall idea of the steps you will be performing. If you are not conﬁdent you can perform the tasks as described here, LSI Logic suggests getting assistance.

• Open your PC cabinet and select an appropriate open PCI slot

• Insert the host adapter board

• Connect the internal and external SCSI peripherals

• Terminate the SCSI bus

• Set the peripheral SCSI IDs

• Make any conﬁguration changes

• Close your PC cabinet

• Install the software

The SCSI host adapter acts on your computer’s behalf as the host to your suite of SCSI peripherals. Each chain of SCSI peripheral devices and their host adapter work together, and are referred to as a SCSI bus.

Each SCSI host adapter that you install can act as host for up to 15 peripheral devices, not including the adapter itself.

2.2.2 Inserting the Host Adapter

4.333 pc

For safe and proper installation, you will need the user’s manual supplied with your computer. Perform the following steps to install the LSIU160.

Step 1. Ground yourself before removing this host adapter board. Step 2. Remove the LSIU160 from the packing and check that it is not

damaged.

An example of this host adapter board is shown in Figure 2.1.

A more detailed drawing is located in Figure A.1. Step 3. Switch off the computer and unplug power cords for all

components in your system. Step 4. Remove the cover from your computer per the instructions in

the user’s manual for your system to access the PCI slots.

44.25 pc

Caution: Ground yourself by touching a metal surface before

removing the cabinet top. Static charges on your body can damage electronic components. Handle plug-in boards by the edge; do not touch board components or gold connector contacts. The use of a static ground strap is recommended.

Step 5. Locate the slots for PCI plug-in board installation.

Refer to the user’s manual for your computer to conﬁrm the

location of the PCI slots.

The LSIU160 requires a 32-bit or 64-bit PCI slot that allows bus

master operation. If a 32-bit PCI slot is used, bits [31:1] of the

J1 connector are inserted while bits [64:32] remain uninserted.

See Figure 2.2.

Note: For the LSIU160 to function as a 64-bit device, it must

inserted in a 64-bit PCI slot. If the LSIU160 is inserted in a 32-bit PCI slot, it will function as a 32-bit device.

Step 6. Remove the blank bracket panel on the back of the computer

aligned with the PCI slot you intend to use.

Save the bracket screw.

2.2.3 Connecting the SCSI Peripherals

4.333 pc

SCSI bus connections to the LSIU160 inside your computer can be made with an unshielded 68 conductor Ultra SCSI TPE ribbon cable (see

Figure 2.3). The lead connected to pin 1 on the cable is marked with a

colored stripe. The connectors on this cable may also be keyed to ensure proper pin-1 connection.

All external SCSI bus connections to the LSIU160 are made with high quality shielded 68 conductor cables (see Figure 2.3). The connectors on this cable are always keyed to ensure proper pin-1 connection.

Note: All the cables shown in Figure 2.3 are included in the

LSI Logic Adapter Board Kit for the LSIU160.

A list of the SCSI bus width and maximum data transfer rate, for various SCSI deﬁnitions, is provided in Table 2.1.

Step 4. Connect the LED cable to connector J6 on the host adapter, as

shown in Figure 2.8. When properly connected, the front panel LED lights when

there is activity on the SCSI bus. Connector J6 is not keyed. The orientation of the LED cable

should not matter as long as all four pins are connected. If the LED does not light during SCSI bus activity from this host adapter, you may have to rotate the LED cable connector 180° on J6.

2.2.6 SCSI Bus Termination

4.333 pc

The devices making up the SCSI bus are connected serially (chained together) with SCSI cables. The ﬁrst and last physical SCSI devices connected on the ends of the SCSI bus must have their terminators active. All other SCSI devices on the bus must have their terminators removed or disabled. Remember that the LSIU160 is also on the SCSI bus—its termination is automatically enabled when it is connected to the end of the bus.

Important: To utilize Ultra2 and faster SCSI performance, you must

only have LVD devices on the bus. Do not mix any SE devices with LVD devices or the entire bus will drop to SE, limiting bus performance to Ultra SCSI levels.

The peripheral device terminators are usually set with jumpers, resistor modules, or with a switch on the peripheral. Refer to the peripheral manufacturer’s instructions and to the user’s manual for your computer for information on how to identify the terminator type/setting for each device and how to set/change it.

44.25 pc

Caution: The autoenable/disable sensing feature on the LSIU160

may enable termination erroneously if it is directly cabled to another SCSI device or host adapter using the same sensing method. The LSIU160 senses the presence of SCSI devices by detecting the ground signal on conductor 50 of the SCSI cable.

The LSIU160 automatically controls SCSI bus termination for three different bus conﬁgurations, depending on how it is connected (see

Figure 2.1). The three bus conﬁgurations are:

• Section 2.2.6.1, “Internal Bus Connections”

• Section 2.2.6.2, “External Bus Connections”

• Section 2.2.6.3, “Internal and External Bus Connections”

Termination on the LSIU160 host adapter for these three different bus conﬁgurations is discussed below.

2.2.7 Setting SCSI IDs

4.333 pc

You must set each SCSI device and the host adapter to a separate SCSI ID 0 through 15. SCSI ID 7 is the preset host adapter setting, giving it the highest priority on the SCSI bus. If you plan to boot your computer from a SCSI hard disk drive on the SCSI bus, that drive should have the lowest SCSI ID on the bus. Typically, SCSI ID 0 is used; however, for system performance optimization, an ID other than 0 (zero) can be used.

Chapter 3, “Conﬁguring the LSIU160,” explains how to set the host

adapter ID using the LSI Logic SCSI BIOS Conﬁguration Utility. The peripheral device SCSI IDs are usually set with jumpers or with a

switch on the peripheral. Refer to the peripheral manufacturer’s instructions and to the user’s manual for your computer to determine the ID of each device and how to change it.

44.25 pc

Note: You must not have any duplication of SCSI IDs on a SCSI

bus.

Step 1. Determine the SCSI ID of each device on the SCSI bus. Note

any duplications.

Step 2. Make any necessary changes to the SCSI IDs to eliminate

duplicates and record the IDs for future reference.

Table 2.3 is provided as a place to keep this record.

• Section 3.2, “The LSI Logic SCSI BIOS Conﬁguration Utility Menus,”

page 3-3

13.851 pc

34.732 pc

3.1 Overview of the SCSI BIOS Conﬁguration Utility

The LSIU160 is loaded with LSI Logic SCSI BIOS and Conﬁguration Utility Version 4.16 (or greater). This section describes the process you need to follow to change conﬁguration settings on your board.

The SDMS SCSI BIOS provides support for the BIOS Boot Speciﬁcation (BBS), which allows you to choose which device to boot from by selecting the priority.

To use this feature, the system BIOS must also be compatible with the BBS. If your system supports the BBS, then you will use the system BIOS setup menu to select the boot and drive order. In the system BIOS setup, the Boot Connection Devices menu appears with a list of available boot options. Use that menu to select the device and rearrange the order. Then exit to continue the boot process.

In most cases you should not need to change the default conﬁguration of the host adapter. You may decide to alter these default values if there is a conﬂict between device settings or if you need to optimize system performance.

There are four sets of conﬁgurations you can change. You make changes on subordinate menus called from the Main Menu, which is opened when

LSIU160 PCI to Single Channel Ultra160 SCSI Host Adapter 3-1

48.583 pc

52.5 pc

3.75 pc 10.25 pc 11.25 pc 38.25 pc

34.5 pc

you start the Conﬁguration Menu. The subordinate menus are listed

4.333 pc

below.

• Adapter properties

• Device properties

• Adapter boot list

• Global properties

All these properties are controlled by menus you access through the conﬁguration utility Main Menu. The Main Menu also gives an overview of some properties of installed LSI Logic host adapter boards.

3.1.1 Starting the Conﬁguration Utility

You can see the version number of your LSI Logic SCSI BIOS in a banner displayed on your computer monitor during boot. If the utility is available, the following message also appears on your monitor:

44.25 pc

Press Ctrl-C to start LSI Logic Configuration Utility...

This message remains on your screen for about ﬁve seconds, giving you time to start the utility. If you press “Ctrl-C,” the message changes to:

Please wait, invoking LSI Logic Configuration Utility...

After a brief pause, your computer monitor displays the Main Menu of the LSI Logic SCSI BIOS Conﬁguration Utility.

These messages may appear during the boot process:

• “Adapter removed from boot order, parameters will be

updated accordingly” appears when an adapter is removed from

the system or relocated behind a PCI bridge.

• “Configuration data invalid, saving default

configuration!” appears if none of the information in the NVRAM

is valid.

• “Found SCSI Controller not in following Boot Order List,

to Add: Press Ctrl-C to start LSI Logic Configuration Utility... ” appears when less than four adapters are in the boot

order and more adapters exist than are shown.

NonVolatile Random Access Memory (NVRAM) is available on the

4.333 pc

LSIU160. Changes can be made and stored using this menu driven utility.

Important: This utility is a powerful tool. If, while using it, you somehow

disable all of your controllers you can recover. Pressing Ctrl-E after memory initialization during a reboot allows you to re-enable and reconﬁgure.

Note: Not all devices detected by the Conﬁguration Utility can be

controlled by the BIOS. Devices such as tape drives and scanners require that a device driver speciﬁc to that peripheral be loaded. This device driver is provided by the device manufacturer.

3.1.2 Exiting the SCSI BIOS Conﬁguration Utility

44.25 pc

Since most changes only take effect after the system reboots, you must exit properly from the Conﬁguration Utility. The proper exit technique is described in Section 3.2.7, “Exit Menu,” page 3-20. It also describes exiting the subordinate menus.

3.2 The LSI Logic SCSI BIOS Conﬁguration Utility Menus

This section describes the menu system of the LSI Logic SCSI BIOS Conﬁguration Menu System.

3.2.1 Using the Menus

You make your conﬁguration changes in the main area of the menu. As in the example menus, it is lighter in color than the header or footer areas. The commands you use to make changes are shown in the footer area and described in Table 3.1. Settings with black text can be changed, settings with white text cannot. This is true regardless of whether the Color or Mono setting is chosen in the Global Properties Menu (Figure 3.6).

CHS Mapping Conﬁguration

[SCSI Plug and Play Mapping / Alternate CHS Mapping]

Spinup Delay (Seconds)

Conﬁguration [1 to 15]

Deﬁnes how the Cylinder Head Sector (CHS) values are mapped onto a disk without pre-existing partition information. SCSI Plug and Play Mapping automatically determines the most efﬁcient and compatible mapping. Alternate CHS Mapping utilizes an alternate, possibly less efﬁcient mapping that may be required if a device is moved between adapters from different vendors. Caution: Neither of these options has any effect after a disk has been partitioned using the FDISK command. The FDISK utility is a tool that the user can use to delete partition entries, one or all of them. If all partition entries are deleted, it is necessary to reboot to clear memory or the old partitioning data will be reused, thus nullifying the previous operation. Use care to ensure that the correct disk is the target of an FDISK command.

Indicates the delay in seconds between spinups of devices attached to an adapter. Staggered spinups balance the total electrical current load on the system during boot. The default value is 2 seconds.

Secondary Cluster Server

Conﬁguration [Yes / No]

Indicates whether an adapter has one or more devices attached that are shared with one or more other adapters and therefore, the LSI Logic SCSI BIOS should avoid SCSI bus resets as much as possible. This option allows the user to enable an adapter to join a cluster of adapters without doing any SCSI bus resets. This is a requirement for Microsoft Cluster Server. The default value is No with an alternate option of Yes.

Termination Control Conﬁguration

[Auto / Off]

If available, the ﬁeld indicates whether an adapter has automatic termination control. Auto means that the adapter automatically determines whether it should enable or disable its termination. Auto is the default state unless termination is done manually, in which case, the conﬁguration is Off.

Indicates whether to scan for this SCSI identiﬁer at boot time. Utilizing this setting allows you to ignore a device. This decreases boot time by disabling inquiry of unused SCSI identiﬁers. Set this option to No if there is a device that you do not want to be available to the system. Also, on a bus with only a few devices attached, the user can speed up boot time by changing this setting to No for all unused SCSI IDs.

Indicates whether to scan for LUNs greater than zero for a device. LUN 0 is always queried. This option should be used if a multi-LUN device responds to unoccupied LUNs or if it is desired to reduce the visibility of a multi-LUN device to LUN 0 only. Set this option to No if you have problems with a device that responds to all LUNs whether they are occupied or not. Also, if a SCSI device with multiple LUNs exists on your system but you do not want all of those LUNs to be available to the system, then set this option to No. This will limit the scan to LUN 0.

Indicates whether to allow a device to disconnect during SCSI operations. Some (usually newer) devices run faster with disconnect enabled, while some (usually older) devices run faster with disconnect disabled.

Indicates the maximum allowable time for completion of a SCSI operation in seconds. Since time-outs provide a safeguard that allows the system to recover should an operation fail, it is recommended that a value greater than zero be used. A value of zero allows unlimited time for an operation to complete and could result in the system hanging (waiting forever) should an operation fail. Note: This ﬁeld is executable and must be selected with the Enter key. You also input the new value with the number keys from the keyboard, not the number pad.

This ﬁeld indicates whether to allow the use of queue tags for a device. Currently the BIOS does not use queue tags. This item speciﬁes queue tag control to higher level device drivers.

Indicates whether this device can be selected as the boot device. This option is only applicable to devices attached to adapter number zero in the boot list on non-BBS systems. It provides primitive BBS ﬂexibility to non-BBS systems.

Format Executable Allows low-level formatting on a disk drive, if enabled.

Low-level formatting will completely and irreversibly erase all data on the drive. To low level format a device, select the device from the menu and use the arrow keys to move the cursor to the Format column. Press Enter. Note: Formatting will default the drive to a 512-byte sector size even if the drive had previously been formatted to another sector size.

A.2 Operational Environment

The LSIU160 is designed for use in PCI computer systems with an ISA/EISA bracket type. SDMS operates the board, but the design of the board does not prevent the use of other software. An on-board ﬂash memory device is provided to allow BIOS code and open boot code support through PCI and a serial EEPROM.

A.2.1 The PCI Interface

The PCI interface operates as a 64-bit DMA bus master. The connection is made through edge connector J1, which provides connections on both the front and back of the board. The signal deﬁnitions and pin numbers conform to the PCI Local Bus Speciﬁcation Revision 2.2 standard.

Table A.2 and Table A.3 show the signal assignments. The PCI portion

of the LSI53C1010 device is powered from the onboard +3.3 V regulator.

44.25 pc

Note: The +3.3 V pins are tied together and decoupled with high

frequency bypass capacitors to ground. No current from these 3.3 V pins is used on the board. The board derives power from the +5 V pins, directly and through a 3.3 V voltage regulator. The PCI +3 V/+5 V pins are used to differentiate between a 5 V or a 3.3 V PCI environment.
