Features 1-3

1.3 Interface Descriptions

This section provides a more detailed explanation about the PCI
Interface, the SCSI Interface, the SCSI Activity LED Interface, and Wide
Ultra2 SCSI.

1.3.1 The PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O
components to a PC processor and memory subsystem. The PCI
functionality for the LSI21002 is contained within the LSI53C896 PCI
Dual Channel SCSI Multifunction Controller. The LSI53C896 connects
directly to the PCI bus and generates timing protocol in compliance with
the PCI specification.

The PCI interface operates as a 32-bit DMA bus master. The connection
is made through edge connector J1 (see Figure 2.1). The signal
definitions and pin numbers conform to the PCI Local Bus Specification
Revision 2.1 standard. The LSI21002 conforms to the PCI univ ersal
signaling environment for a 5 V or 3.3 V PCI bus.

1.3.2 The SCSI Interface

The SCSI functionality for the LSI21002 is contained within the
LSI53C896 chip. The LSI53C896 connects directly to the two SCSI
buses for SE or LVD SCSI applications and generates timing and
protocol in compliance with the SCSI standard. One SCSI interface
operates at a burst transfer rate of up to 40 Mbytes/s for wide Ultra SCSI
transfers, and the other up to 80 Mbytes/s for wide Ultra2 SCSI transfers.

Channel A is SE only with active autosensing termination. The
Channel A interface is made through connectors J2, J3, and J4.
Connector J2 is a 68-pin high density latching right angle receptacle for
internal SCSI connections. Connector J3 is a 50-pin high density right
angle receptacle that protrudes throughout the ISA/EISA bracket.
Connector J4 is a 50-pin narrow (ribbon) internal connector.

Channel B may be either SE or LVD with active termination always
enabled. The Channel B interface is made through connector J5. J5 is a
68-pin high density latching right angle connector for internal SCSI
connections.

1-4 Using the LSI21002

See Figure 2.1 for the location of these connectors.
The LSI21002 supplies SCSI bus TERMPWR through a blocking diode

and self-resetting 1.5 A short circuit protection device. An on-board LED
lights up when TERMPWR is shorted and has turned off.

A 40 MHz oscillator is installed on the LSI21002 to provide the clock
frequency to the LSI53C896 that is necessary to support SCSI transfers.

1.3.3 SCSI Activity LED Interface

The LSI21002 LED interface is a four-wire arrangement that allows
connection of an LED harness to the board. The connector on the
LSI21002 is J6 for both channels. See Table A.7 in Appendix A for the
signal name and pin numbers for this LED interface.

1.3.4 Wide Ultra2 SCSI

The LSI21002 has full support for Wide Ultra2 SCSI. This interface is an
extension of the SCSI-3 family of standards that expands the bandwidth
of the SCSI bus to allow faster synchronous data transfers, up to
80 Mbytes/s. Wide Ultra2 SCSI provides a doubling of the data rate over
the Ultra SCSI interface, while it allows increased cable length and more
devices than Ultra SCSI interfaces.

Special SCSI cables are specified for operation with Wide Ultra and
Ultra2 SCSI devices, and you must consider the total number of devices
and the length of your SCSI bus when setting up y our system. The
section on connecting your SCSI peripherals in Chapter 2, "Installing the

LSI21002," provides a more detailed explanation of SCSI bus

connections. See Table 1.1for maximum bus lengths in meters.
When you purchased the LSI21002 kit, the cable provided in the kit is

matched for a Fast/Ultra/Ultra2 SE or LVD operation. This cable also has
built-in LVD termination since most Ultra2 hard disk drives are not made
with on-board LVD termination.

1. This parameter may be exceeded in point-to-point and engineered

applications.

2. LVD was not defined in the original SCSI standards for this speed. If all

deviceson the bus support LVD, then 12-meter operation is possible at this
speed. However, if any device on the bus is SE only, then the entire bus
switches to SE mode, and the distances in the SE column apply.

3. SE and high power differential are not defined at Ultra2 speeds.

Chapter 2
Installing the LSI21002

This chapter describes installing the LSI21002 into PCI computer
systems 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, “Setting Interrupts (Exceptional Cases),” page 2-24

• Section 2.4, “Completing the Installation,” page 2-25

2.1 Quick Installation Procedure

This section provides quick setup instructions for the experienced
computer user with prior host adapter installation and SCSI bus setup
experience. If you prefer more detailed guidance for installing the
LSI21002, please follow the instructions in Section 2.2, “Detailed

Installation Procedure.”

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

Step 1. Before proceeding, ground yourself so that a static discharge

does not damage the board. Remove the LSI21002 from the
packing and check that it is not damaged. An example of this

host adapter board is shown in Figure 2.1.
Step 2. Switch off and unplug the system.
Step 3. 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;

LSI21002 PCI to Dual Channel SCSI Host Adapter 2-1

do not touch board componentsor gold connector contacts.
The use of a static ground strap is recommended.

Step 4. Locate the slots for the PCI plug-in board installation. A 32-bit

slot should be used. The LSI21002 will work in a 64-bit slot, but

only 32 bits are used. The LSI21002 requires a PCI slot that

allows bus master operation. See Figure 2.2.
Step 5. Remove the blank panel on the back of the computer aligned

with the PCI slot that you intend to use. Save the bracket screw.
Step 6. Carefully insert edge connector J1 of the host adapter into the

PCI slot. Make sure the edge connector is properly engaged

before pressing the board into place. See the example shown

in Figure 2.2.

Note.

You may notice that the components on the PCI host
adapter face the opposite way from those on other non-PCI
plug-in boards you have in your system. This is correct, and
the board is keyed to go in only one way.

Step 7. The bracket around connector J3 should fit where the blank

panel was removed. Secure it with the bracket screw before

making the internal and external SCSI bus connections (see

Figure 2.2).

Step 8. If y ou are connecting any internal SCSI devices, plug a 68-pin

connector on the end of the internal SCSI ribbon cable into

connector J2 or J5, or plug a 50-pin connector into J4 for an

8-bit SCSI (see Figure 2.1).Makecertaintomatchpin1onall

connectors.

Note.

It is possible to use both internal connectors if no external
devices are attached to the host adapter. You may use only
two of the three connectors at once.

Step 9. Connect your computer’s LED cable if desired. This LED cable

drives the front panel LED found on most PC cabinets to

indicate activity on the SCSI bus. See Table A.7 in Appendix A

for the signal name and pin numbers for this LED interface.
Step 10. Replace the cabinet cover as described in the user’s manual for

to load the driver software f or your particular operating system.

2.2 Detailed Installation Procedure

This section provides step-by-step instructions for installing your
LSI21002 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.” If you are not confident that you can perform the

tasks as described here, LSI Logic suggests getting assistance.

2.2.1 Before You Start

Before you star t, look through the task list below to get an overall idea
of the steps to perform.

• Open your PC cabinet and select an open PCI slot

• Insert the host adapter

• Connect your internal and external SCSI peripherals

• Terminate the SCSI bus

• Set the peripheral SCSI IDs

• Make any configuration changes

• Replace your PC cabinet cover

• 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 they are referred to as a SCSI
bus.

Detailed Installation Procedure 2-3

2.2.2 Inserting the Host Adapter

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

Step 1. Before proceeding, ground yourself so that a static discharge

does not damage the board. Remove the LSI21002 from the

packing and check that it is not damaged. An example of this

host adapter board is shown in Figure 2.1.
Step 2. Switch off and unplug power cords for all components in your

system.
Step 3. Remove the cabinet cover on your computer to access the PCI

slots.

Caution: Ground yourself by touching a metal surface before

removing the cabinet cover. 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 4. Locate the slots for the PCI plug-in board installation. A 32-bit

slot should be used. The LSI21002 will work in a 64-bit slot, but

only 32 bits are used. The LSI21002 requires a PCI slot that

allows bus master operation. See Figure 2.2.
Step 5. Remove the blank panel on the back of the computer aligned

with the PCI slot that you intend to use. Save the bracket screw.
Step 6. Carefully insert edge connector J1 (see Figure 2.1) of the host

adapter into the PCI slot. Make sure the edge connector is

properly engaged before pressing the board into place as

shown in Figure 2.2.
Step 7. You may notice that the components on the PCI host adapter

face the opposite way from those on other non-PCI adapter

boards you have in your system. This is correct, and the board

is keyed to go in only one way.

2-4 Installing the LSI21002

Step 8. The bracket around connector J3 (see Figure 2.1) should fit

where you removed the blank panel. Secure it with the bracket

screw (see Figure 2.2) before making the internal and external

SCSI bus connections.

2.2.3 Connecting the SCSI Peripherals

All internal SCSI bus connections to the LSI21002 are made with an
unshielded, 68- or 50-conductor ribbon cable (see Figure 2.3). On e side
of this cable is marked with a color to indicate the pin-1 side. The
connectors on this cable are keyed to ensure a proper pin-1 connection.
Use Ultra/Ultra2 rated cables for these bus speeds. (See Table 1.1 in

Chapter 1.)

For convenience, Channel A also has a 50-pin narr ow (ribbon)connector.
Some internal cables come with an SE/LVD terminator on one end. This
end should be furthest from the host adapter.

All external SCSI bus connections to the LSI21002 are made with a
shielded, 50-pin high density cable (see Figure 2.3). The connectors on
this cable are always keyed to ensure a proper pin-1 connection.

2.2.3.1 Making Internal SCSI Bus Connections

This section provides step-by-step instructions about making internal
SCSI bus connections:

Step 1. To connect an internal SCSI device, plug the 68- pin connector

end of a wide internal SCSI ribbon cable into connector J2 or
J5. See the example in Figure 2.4.

Step 2. Plug the 68-pin connector on the other end of the wide internal

SCSI ribboncable into the SCSI connector on the internal SCSI
device. Pin 1 must match on all connections. An example of this
connection appears in Figure 2.5.

Figure 2.5 Internal SCSI Ribbon Cable to Internal SCSI Device

Detailed Installation Procedure 2-9

Step 3. To plug in additional internal SCSI devices, use an internal

SCSI ribbon cable with the required number of connectors
attached along its length. See the example in Figure 2.6.

Figure 2.6 Connecting Additional I nternal SCSI Devices

2-10 Installing the LSI21002

An example of multiple internal SCSI de v ices chained together is
shown in Figure 2.7. Make sure to match pin 1 on all connections.

Figure 2.7 Multiple Internal SCSI Devices Chained Together

Detailed Installation Procedure 2-11

Step 4. Most PC cabinets are designed with a front panel LED, which

may already be connected to an existing IDE controller. You
may connect this LED cable to your SCSI host adapter, as
shown in Figure 2.8. This connection causes the front panel
LED to indicate activity on the SCSI bus.

The Busy LED connector J6, shown in Figure 2.1, is not keyed.
The J6 connector is a 4-pin one row right angle header for both
Channel A and Channel B.

Some LED cables have only two wires. In this case, place the
connector on one end of J6. If the LED does not light during
SCSI bus activity from this host adapter, you may have to rotate
the LED connector 180

° on J6.

See Table A.7 in Appendix A for connector pinout information.

Figure 2.8 SCSI LED Connector

2-12 Installing the LSI21002

2.2.3.2 Making External SCSI Bus Connections

This section provides step-by-step instructions about making external
SCSI bus connections:

Step 1. To connect external SCSI devices to the LSI21002, plug the

50-pin high density connector on one end of a shielded external
high density cable (see Figure 2.3) into the host adapter
connector J3 (see Figure 2.1 and Figure 2.9).

This connector is now bracketed onto the back panel of your
computer. Figure 2.9 shows this connection.

Figure 2.9 External Cable to Host Adapter

Detailed Installation Procedure 2-13

Step 2. Plug the 50-pin high density connector on the other end of the

shielded external SCSI cable into the SCSI connector on the
external SCSI device. An example of this connection is shown
in Figure 2.10.

Figure 2.10 External Cable to External SCSI Device

2-14 Installing the LSI21002

Step 3. To connect more than one e x ternal SCSI device to the host

adapter, chain them together with shielded external SCSI
cables. See the example in Figure 2.11.

Figure 2.11 Multiple External SCSI Devices Chained Together

2.2.4 SCSI Bus Termination

The devices that make 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 be terminated. All other
SCSI devices on the bus must have their terminators removed or
disabled.

Detailed Installation Procedure 2-15

Remember: The LSI21002 is also on the SCSI bus, and its termination

is automatically enabled when it is connected to the end of
the bus.

LVD peripheral de vices are normally terminated with
external terminators, but are sometimes set with jumpers or
with a switch on the peripheral. Refer to the peripheral
manufacturer’s instructions and to your computer user’s
manual for information on how to identify the terminator
setting of each device and how to change it.

Caution:

The autoenable/disable sensing feature of Channel A on
the LSI21002 may enable termination erroneously if it is
directly cabled to another SCSI device or host adapter
using the same sensing method. The LSI21002 senses
SCSI de vices by detecting the ground signal on
conductor 50 of a 68-conductorSCSI cable or conductor 22
of a 50-conductor SCSI cable. Only the SE/LVD terminators
on Channel B will always remain on.

When connecting another host adapter to a connector, termination must
be disabled on the board that is not at the end of the bus through
software control.

The LSI21002 automatically contr ols SCSI bus termination for f our
different bus configurations, depending on the use of connectors (see

Figure 2.1). The four bus configurations are:

• Only for internal SCSI connections,

• Only for an external SCSI connection, and

• Connections to both internal and external SCSI connectors

• Connections to both internal connectors.

Termination on the LSI21002 for these four different bus configurations
are discussed below. Please note that only SE termination control is
allowed on Channel A.

2.2.4.1 Internal SCSI Connections

If only internal SCSI device connections on the hos t adapter have been
made, then terminate the last internal device on the SCSI bus. You must
disable the termination on all other devices. Termination on the LSI21002

2-16 Installing the LSI21002

is automatically enabled for Channel A. The termination for Channel B is
enabled all the time.

Figure 2.12 shows an example of how termination is determined for this

SCSI bus configuration.

Figure 2.12 Internal SCSI Device Termination

Detailed Installation Procedure 2-17

2.2.4.2 External SCSI Connections

If only external SCSI device connections to the host adapter have been
made, then terminate the last external device on the SCSI bus. You must
disable the termination on all other devices. Termination on the host
adapter is automatically enabled for Channel A.

Figure 2.13 shows an example of how termination is determined for this

SCSI bus configuration on the host adapter external Channel A.

If internal and external SCSI devices are connected to the host adapter,
then terminate the last internal and external devices on the SCSI bus.
You must disable the termination on all other devices. Termination on
Channel A of the host adapter is automatically disabled in this case.

2.2.4.4 Internal SCSI Connections for both Internal Connectors

If internal SCSI device connections to both internal connectors (J2 and
J4) on your host adapter have been made, then terminate the internal
devices on each end of the SCSI bus. You must disable the termination
on all other devices. Termination on Channel A of your host adapter is
automatically disabled in this case. Remember, you must not use the
external connector J3 if you use both internal connectors.

2.2.4.5 Setting SCSI IDs

You must set each SCSI device and the host adapter to a separate SCSI
ID, 0–15 for a 16-bit SCSI. 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 hard disk drive on the SCSI bus, that drive should have
SCSI ID 0, or the lowest SCSI ID on the bus. Chapter 3, "Configuring the

Host Adapter," 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. You must have no duplication of
SCSIIDsonaSCSIbus.

Note:

SCAM support is turned off by default for the BIOS version

4.11.00 and above. You may choose to turn this on to assist
in assigning SCSI IDs.

Determine the SCSI ID of each device on the SCSI bus. Note any
duplications.

2-22 Installing the LSI21002

Make any necessary changes to the SCSI IDs and record the IDs for
future reference. Table 2.1 is provided as a place to keep this record.

Detailed Installation Procedure 2-23

2.3 Setting Interrupts (Exceptional Cases)

Normally, you do not change the default interrupt routing for the
LSI21002, since performance is usually increased by having two
separate interrupts.

However, if your system does not support two separate interrupts,
INTA/INTB/ (see Figure A.1) is provided to change the interrupt routing.
This capability requires enabling the INTA/INTB/ to act as a jumper for
special configuration purposes. This feature is not packaged with the
standard LSI21002, as the default interrupt routing is sufficient for most
systems.

In the exceptional case, where a user would require jumper settings,

Table 2.2 explains these settings:

Table 2.2 Setting Interrupts

Chapter 3
Configuring the Host
Adapter

This chapter describes configuring the LSI21002 and includes these
topics:

• Section 3.1, “When to Configure the LSI21002,” page 3-1

• Section 3.2, “Starting the SCSI BIOS Configuration Utility,” page 3-2

• Section 3.3, “Exiting the SCSI BIOS Configuration Utility,” page 3-14

3.1 When to Configure the LSI21002

In most cases you should not need to change the default configuration
of your 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.

Table 3.1 and Table 3.2 list the configuration settings you can change.
The global settings effect your host adapter andall SCSI devices that are
connected to it. The device settings aff ect only individual SCSI devices.

3.2 Starting the SCSI BIOS Configuration Utility

If you have SCSI BIOS Version 4.XX, and it includes the LSI Logic SCSI
BIOS Configuration Utility, you can change the default configuration of
your SCSI host adapters. You may decide to alter these default values if
there is a conflict between device settings or if you need to optimize
system performance.

You can see the version number of your 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:

Press Ctrl-C to sta rt LSI Logic Configur ation Utility...

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

Please wait, invoking LSI Logic Confi guration Utility...

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

NonVolatile Random Access Memory (NVRAM) is provided on the
LSI53C896 SCSI device.

3-2 Configuring the Host Adapter

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

disable all of your controllers, pressing Ctrl-A (or Ctrl-E on
version 4.04 or later) after memory initialization during
reboot allows you to re-enable and reconfigure.

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.

3.2.1 Configuration Utility Main Menu

When you start the LSI Logic SCSI BIOS Configuration Utility, the Main
Menu appears. This menu displays a list of up to four LSI Logic PCI to
SCSI host adapters and information about each of them. The LSI21002
appears on the menu as two LSI53C896 entries; one for each channel.
To select an adapter, use only the arrow keys and enter key. Then, you
can view and/or change the current settings for that adapter and the
SCSI devices attached to it.

You can select an adapter only if Current Status is “On”. Changes are
possible since NVRAM is present on this host adapter.

The settings in this menu are global settings that affect the selected host
adapter and all SCSI devices attached to it.

SCAM Support – The LSI Logic BIOS Version 4.XX and above
supports the SCSI Plug and Play protocol called SCAM. SCAM support
by default is turned off in versions 4.11.00 and later for the LSI53C896
device. You may choose to turn it on. Note that if this BIOS is flashed
onto a board with existing settings, then these settings will not be
changed to reflect the new BIOS defaults. Go into the Configuration
Utility to change settings.

3-8 Configuring the Host Adapter

Parity – The LSI Logic PCI to SCSI host adapters always generate
parity, but some older SCSI de vices do not. Therefore, you are offered
the option of disabling parity checking.

Note:

When disabling parity checking, it is also necessary to
disable disconnects for all devices, as parity checking for
the reselection phase is not disabled. If a device does not
generate parity, and it disconnects, the I/O never completes
because the reselection never completes.

Host SCSI ID – In general, it is suggested that you do not change your
host adapter ID from the default value of 7, as this gives it the highest
priority on the SCSI bus.

Scan Order – This option allows the user to tell the SCSI BIOS and
device drivers to scan the SCSI bus from low to high (0 to max) SCSI
ID, or from high to low (max to 0) SCSI ID. If you have more than one
device on the SCSI bus, changing the scan order changes the order in
which drive letters are assigned by the system. Drive order may be
reassigned differently in systems supporting the BIOS Boot Specification
(BBS). See t he PCI Storage Device Management System SDMS 4.0
User’sGuide, Chapter2 “SCSI BIOS” for additional information regarding
BBS.

Note:

The scan order option may conflict with operating systems
that automatically assign a drive order.

Removable Media Support – This option defines the removable media
support for a specific drive. When this option is selected, a window
appears with three choices:

• None

Indicates there is no removable media support whether the drive is
selected in BB S as being first, or first in scan order in non-BBS.

• Boot Drive Only

Provides removable media support for a removable hard driv e if it is
first in the scan order.

• With Media Installed

Provides removable media support wherever the drive(s) actually
resides.

Starting the SCSI BIOS Configuration Utility 3-9

One of these choices can be selected by highlighting it and pressing
Enter.

CHS Mapping – This option defines the cylinder head sector (CHS)
values that will be mapped onto a disk without pre-existing partitioning
information. SCSI Plug and Play Mapping is the default value.

To support interchange with noncompatible systems, there is another
option that can be selected by choosing CHS Mapping and then
cursoring to Alterna te CH S Mappin g.

Note:

Neither of these options will have any affect after the disk
has been partitioned with the FDISK command.

To remove partitioning, two options are available:

• Reformat the disk using the Format Device option. See Section

3.2.2.2, “Device Selections Menu.”

• Use the FDISK/MBR command at the C:\ prompt, where MBR

represents master boot record.

Important: Reformatting the disk or using FDISK/MBR erases all

partitioning and data that exists. Be careful that you target
the correct disk when using either the Format utility or the
FDISK/MBR command.

After clearing the partitions and data, it is necessary to
reboot and clear the memory or the old partitioning data will
be reused.

Spinup Delay (seconds) – This option allows the user to stagger spin
ups between devices for a longer period of time to balance the total
current load. The default value is 2 seconds with choices between 1 and
10 seconds.

This is a power management feature designed to accommodate disk
devices that may have heavy current load during power up. If multiple
drives are being powered up simultaneously and drawing heavy current
loads, then this option staggers the spin ups to limit start-up current.

Secondary Cluster Server – This option allows the user to enable an
adapter to join a cluster of adapters without doing any SCSI bus resets.

3-10 Configuring the Host Adapter

This is a requirement for Microsoft Cluster Server. The default value is
No with an alternate option of Yes.

Termination – This option allows the user to have termination control
providing an adapter has controllable termination. The default value is
Auto termination. The alternate value is Off.

3.2.2.2 Device Selections Menu

Sync Rate (Mbytes/s) – This option defines the maximum data transfer
rate the host adapter attempts to negotiate. The host adapter and a SCSI
device must agree to a rate they can both handle.

Width (Bits) – This option defines the maximum SCSI data width the
host adapter attempts to negotiate. The host adapter and a SCSI device
must agree to a width they can both handle. Only host adapters that can
do 16-bit data transfers have this option enabled.

Disconnect – SCSI devices have the ability to disconnect from the
initiator during an I/O transfer. The disconnect option frees the SCSI Bus

to allow other I/O processes. This option tells the host adapter whether
ornottoallowadevicetodisconnect.Somedevicesrunfasterwith
disconnects enabled (typically newer devices), while some run faster with
disconnects disabled (typically older devices).

Read/Write I/O Time-out (Seconds) – This option sets the amount of
time the host adapter waits for a read, write, or seek command to
complete before trying the I/O transfer again. Since this provides a
safeguard allowing the system to recover if an I/O operation fails, it is
recommended that you always set the time-out to a value greater than
zero.

Note:

If the time-out is set to zero, then the I/O will never time-out.

Scan for Device at Boot Time – Set this option to “No” when there is
a device you do not want to be available to the system. Also, on a bus
with only a fe w devices attached, you can speed up boot time by
changing this setting to “No” for all unused SCSI IDs.

Scan for SCSI Logical Unit Numbers (LUNs) – Set this option to
“No” if you have problems with a device that responds to all LUNs
whether they are occupied or not. For example, if there is a SCSI device
with multiple LUNs 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 LUN0
only.

Queue Tags – This option allows the user to enable or disable the
issuing of queue tags during I/O requests when your device driver can
do this.

Initial Boot – This option allows any device attached to the first adapter
to become the boot device. It provides the users of non-BBS personal
computers with some of the flexibility of a BBS machine.

Format – If enabled, this option allows the user to low-level format a
magnetic disk drive. Low-level formatting will completely and irreversibly
erase all data on the drive. Note that this utility will only format 512-byte
sectors. For other sector sizes, do not use this utility.

Verify – This option allows the user to read all the sectors on a disk
looking for errors. When selected, this option displays the following
message:

Help – This option displays a help screen with information about the
current menu.

Restore Default Setup – This option resets all device selections back
to their optimal settings. Select this option to restore all manufacturing
defaults for the specified adapter. Note that all user customized options
will be lost upon saving after restoring default setup.

Exit this menu – This option allows the user to leave the current menu
screen and return to the previous screen.

discharge. The board carries the CE mark, and meets the requirements
of FCC and CISPR Class B. It is also marked with the FCC
self-certification logo.

A.1.5 Safety Characteristics

The bare board meets or exceeds the requirements of UL flammability
rating 94 V0. The bare board is also marked with the supplier’s name or
trademark, type, and UL f lammability rating. Since this board is installed
in a PCI bus slot, all voltages are below the SELV 42.4 V limit.

A.2 Operational Environment

The LSI21002 is designed for use in PCI computer systems with an
ISA/EISA bracket type. The SDMS software operates the boar d;
however, 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 the PCI bus and a serial EEPROM for
each channel.

A.2.1 The PCI Interface

The PCI interface operates as a 32-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 2.1 standard. The
signal assignments appear in Table A.2 and Table A.3.

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 PCI portion of
the LSI53C896 chip is powered from the 3 V/5 V pins.

A.2.2 The SCSI Interface

The SCSI interface conforms to ANSI X3T10.11/1142.
The SCSI interface operates as two 16-bit, SE or LVD channels, and

supports Fast, Ultra, and Ultra2 SCSI protocols. The interface is made
through connectors J2, J3, and J4 for Channel A and J5 for Channel B.

J2 is a 68-pin high density latching right angle connector for internal
SCSI connections to Channel A. J3 is a 50-pin high density right angle
connector that protrudes through the ISA/EISA bracket for external
connections to Channel A. Also on Channel A is connector J4, which is
a 50-pin narrow (ribbon) connector for internal connections. Channel A
has auto-sensing, active SE SCSI termination.

J5 is a 68-pin high density latching right angle connector for internal
SCSI connections to Channel B. Channel B has Active, SE or LVD SCSI
termination that is always enabled.

SCSI termination power is supplied by the board.
Tables A.4, A.5, A.6,andA.7 show the signal assignments for J2, J3, J4

and J5 respectively (see Figure 2.1,inChapter 2).
