1.3 Interface Descriptions

This section provides a more detailed explanation about the PCI

Interface, the SCSI Interface, and Ultra SCSI.

1.3.1 The PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O

components to the processor and memory subsystems in a high-end PC.

The PCI functionality for the LSIU40HVD is contained within the

LSI53C876 PCI to SCSI I/O Processor chip. The LSI53C876 chip

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 the 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 LSIU40HVD 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 LSIU40HVD is contained within the LSI

Logic LSI53C876. The LSI53C876 chip connects directly to the two SCSI

buses and generates timing and protocol in compliance with the SCSI

standard.

The SCSI interface on the LSIU40HVD operates as a 16-bit,

synchronous or asynchronous, differential bus, and supports Ultra SCSI

protocols and 16-bit arbitration. Each interface is made through the

connectors J2 and J3 (for Channel A), or J5 and J6 (for Channel B).

Connectors J2 and J5 are 68-pin high-density, right-angle receptacles.

Interface Descriptions

1-3

Connectors J3 and J6 are shielded 68-pin VHDCI right-angle receptacles

that protrude through the back panel bracket. See Figure 2.1 for the

location of these connectors.

Differential SCSI active termination is provided on the LSIU40HVD.

Termination is automatically enabled when only one of the connectors J2

and J3 (or J5 and J6) is used, or when an 8-bit device is connected to

the 16-bit J3 or J6 connectors. The LSIU40HVD supplies SCSI bus

TERMPWR (termination power) through a blocking diode and a

self-resetting 1.5 A short circuit protection device. An on-board LED

lights when TERMPWR is off. Separate jumpers for each channel allow

user override of termination.

A 40 MHz oscillator is installed on the LSIU40HVD to provide the clock

frequency to the LSI53C876 chip that is necessary to support Wide Ultra

SCSI transfers of up to 40 Mbytes/s.

1.3.3 Ultra SCSI

The LSIU40HVD has full support for Ultra SCSI as well as supporting

Fast SCSI simultaneously. Ultra SCSI is an extension of the SCSI-3

family of standards that expands the bandwidth of the SCSI bus, allowing

faster synchronous data transfers. Special SCSI cables are speciﬁed for

operation with Ultra SCSI devices, and you must consider the total

number of devices and the length of your SCSI bus when setting up your

system. See the section on connecting your SCSI peripherals in

Chapter 2, "Installing the LSIU40HVD," for a more detailed explanation

of SCSI bus connections.

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

LSIU40HVD, please follow the instructions in 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 the host adapter board.

Remove the LSIU40HVD from the packing and check that it is

not damaged. An example of this 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.

LSIU40HVD PCI to Dual Channel SCSI Host Adapter

Caution:

Ground yourself by touching a metal surface before han-

dling 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 con-

tacts. The use of a static ground strap is recommended.

Step 4. 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 LSIU40HVD requires a PCI slot

which 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 you intend to use. Save the bracket screw.

Step 6. Carefully insert the edge connector J1 (see Figure 2.1) of the

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

is properly aligned before pressing the board into place. See

the example shown in Figure 2.2.

Note:

You may notice that the components on a 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.

Step 7. The bracket around the connectors J3 and J6 (see Figure 2.1)

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 you are connecting any internal SCSI devices, plug a 68-pin

connector on the end of an internal SCSI ribbon cable into

connector J2 or J5 (see Figure 2.1). Make certain to match pin

one on both connectors. Chain the internal devices on this

cable.

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

to drive the front panel LED found on most PC cabinets to

indicate activity on the SCSI bus.

Step 10. Replace the cabinet cover as described in the user’s manual for

your computer.

Step 11. Make all external SCSI bus connections.

Remember: The SCSI bus requires proper termination, and no

duplicate SCSI IDs.

the bracket screw (see Figure 2.2) before making the internal

and external SCSI bus connections.

2.2.3 Connecting the SCSI Peripherals

SCSI bus connections to the LSIU40HVD inside your computer are made

with an unshielded, 68-conductor ribbon cable (see Figure 2.3). One side

of this cable is marked with a color to indicate the pin-1 side. Sometimes

2-6

Installing the LSIU40HVD

the connectors on this cable are keyed to ensure proper pin-1

connection.

All external SCSI bus connections to the LSIU40HVD are made with

shielded, 68-conductor cables (see Figure 2.3). The connectors on this

cable are always keyed to ensure proper pin-1 connection.

Table 2.1 lists the SCSI bus widths and speeds as established by the

SCSI Trade Association (STA).

2-10

Installing the LSIU40HVD

Step 3. Additional internal SCSI devices are plugged in by using an

internal SCSI ribbon cable with the required number of

connectors attached along its length as shown in Figure 2.6.

An example of this type of chained connection is shown in

Figure 2.7. Make sure to match pin 1 on all connections.

Installing the LSIU40HVD

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

may already be connected to an existing IDE drive. 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 LED connectors J4 and J7 (see Figure 2.1) are not keyed.

The orientation of the LED cable does not matter as long as all

four pins are connected.

Figure 2.8 SCSI LED Connectors

J7

J4

Some LED cables have only two wires. In this case, place the

connector on one end or the other of J4 or J7. If the LED does not

light during SCSI bus activity from this host adapter, you may have

to rotate the LED cable 180° on J4 or J7.

See Table A.5 in Appendix A for connector pinout information.

Detailed Installation Procedure

2-13

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 LSIU40HVD, plug the

68-pin VHDCI connector on one end of a shielded external high

density cable (see Figure 2.3) into the host adapter connector

J3 or J6 (see Figure 2.1).

This connector is now bracketed to the back panel of your

computer. Figure 2.9 shows how this connection is made.

Figure 2.9 External Cable to Host Adapter

2-14

Installing the LSIU40HVD

Step 2. Plug the 68-pin 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 SSI Device

Detailed Installation Procedure

2-15

Step 3. To connect more than one external SCSI device to the host

adapter, you must chain them together with shielded external

SCSI cables. An example of these chained connections is

shown in Figure 2.11.

Figure 2.11 Multiple External SCSI Devices Chained Together

2.2.4 SCSI Bus Termination

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 a set of resistors

called terminators. All other SCSI devices on the bus must have their

terminators removed or disabled.

2-16

Installing the LSIU40HVD

Remember: The LSIU40HVD is also on the SCSI bus; its termination is

automatically enabled when it is connected to the end of

the bus.

Differential peripheral devices 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 the

user’s manual for your computer for information on how to identify the

terminator setting of each device and how to change it.

Caution:

The auto-enable/disable sensing feature on the

LSIU40HVD may enable termination erroneously if it is

directly cabled to another SCSI device or host adapter

using the same sensing method. The LSIU40HVD senses

SCSI devices by detecting the ground signal on conductor

50 of a 68-conductor SCSI cable. If you use an adapter to

connect 8-bit devices externally with a 50-conductor SCSI

cable, the ground signal is detected on conductor 34.

The LSIU40HVD automatically covers SCSI bus termination for three

different bus conﬁgurations, depending on your use of the connectors on

the LSIU40HVD (see Figure 2.1). The three bus conﬁgurations are:

•

only for internal SCSI connections

only for external SCSI connections

for both internal and external SCSI connections

Termination on the LSIU40HVD for these three different bus

conﬁgurations is discussed below.

2.2.4.1

Internal SCSI Connections

If internal SCSI device connections to the host adapter have been made,

you must terminate the last internal device on the SCSI bus. You must

disable the termination on all other devices. Termination on the host

adapter is automatically enabled in this case.

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

SCSI bus conﬁguration.

Detailed Installation Procedure

2-17

Figure 2.12 Internal SCSI Device Termination

2.2.4.2

External SCSI Connections

If external SCSI device connections to the host adapter have been made,

you must 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 in this case.

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

SCSI bus conﬁguration on the LSIU40HVD Channel B.

2.2.4.4

Internal SCSI Connections for both Internal Connectors

If internal SCSI device connection to another LSIU40HVD has been

made, or any connection to a device that uses the same sensing method

for automatic termination as your LSIU40HVD, you must properly set the

termination override jumpers TP2, TP3, TP5, or TP6 (see Figure A.1).

When connecting another LSIU40HVD, or other device that uses the

same termination sensing scheme, you must connect the jumper to both

pins on the TP for the connector used. For example, if another

LSIU40HVD is attached to J3, place the jumper on both stake pins of

TP3.

2.2.5 Setting SCSI IDs

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

SCSI ID 0, or the lowest SCSI ID on the bus. Chapter 3, “Conﬁguring the

LSIU40HVD,” explains how to set your 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

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 and record the

IDs for future reference. Table 2.2 is provided as a place to

keep this record.

2.3 Setting Interrupts

Normally, you do not change the default interrupt routing for the

LSIU40HVD, since performance is usually increased by having two

separate interrupts. However, if your system does not support two

3.1 When to Conﬁgure the LSIU40HVD

In most cases, changing the default conﬁguration of the host adapter is

not necessary. If a conﬂict does exist between device settings, or if a

need exists to optimize system performance, this Conﬁguration Utility

provides the means to change system conﬁgurations.

The conﬁguration settings that may be changed are discussed in

Table 3.1. The global settings affect the host adapter and all SCSI

devices which are connected to it. The device settings affect only

individual SCSI devices.

3.2 Starting the SCSI BIOS Conﬁguration Utility

If you have SCSI BIOS version 4.0 and later, and it includes the

LSI Logic SCSI BIOS Conﬁguration Utility, the default conﬁguration of the

SCSI host adapter(s) can be changed. If a conﬂict does exist between

device settings or if optimizing system performance is necessary, then

use this Conﬁguration Utility.

The version number of the SCSI BIOS appears in a banner displayed on

your computer monitor during boot. If the Conﬁguration Utility is

available, the following message also appears on your monitor:

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 decide to press Control 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.

NVRAM is available on this LSI Logic LSIU40HVD. Changes can be

made and stored to NVRAM using this menu driven utility.

3-2

Conﬁguring the LSIU40HVD

Important: This SCSI BIOS Conﬁguration Utility is a powerful tool. If,

while using it, you somehow disable all of your controllers,

pressing Control A(or Control Eon 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. The device manufacturer provides the

device drivers.

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 in your system and information about each of them.

The LSIU40HVD appears on the menu as two LSI53C875 entries; one

for each channel. To select an adapter, use only the arrow keys and the

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 only if NVRAM is present on your adapter.

Exit this menu

The settings in this menu are global settings that affect the selected host

adapter and all SCSI devices attached to it. One of these choices can

be selected by highlighting it and pressing Enter.

SCAM Support – The LSI Logic BIOS version 4.0 and above supports

the SCSI Plug and Play protocol called SCAM (SCSI Conﬁgured

AutoMatically). SCAM support by default is off in versions 4.09 and later

for the LSI53C876 device. The user may choose to turn this on only if

the system drivers do not require SCAM off. 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 these settings.

Parity – The LSI Logic PCI to SCSI host adapters always generate

parity, but some older SCSI devices do not. Therefore, you are offered

the option of disabling parity checking.

3-8

Conﬁguring the LSIU40HVD

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 – This option refers to the host adapter’s SCSI ID, which

is a unique number used to identify the device on the SCSI bus.

Note:

In general, the user should not change the host adapter ID

from the default value of 7, as this gives it the highest

priority on the SCSI bus. Please also note that if you have

8-bit SCSI devices (narrow), they cannot see host IDs

greater than 7.

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 there is 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 Chapter 2, “SCSI BIOS,” in the PCI Storage Device Management

System SDMS 4.0 User’s Guide for additional information regarding

BBS.

Note:

This 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

Boot Drive Only

With Media Installed

None indicates there is no removable media support whether the drive

is selected in BBS as being ﬁrst, or ﬁrst in scan order in non-BBS.

Boot Drive Only provides removable media support for a removable

hard drive if it is ﬁrst in the scan order.

Starting the SCSI BIOS Conﬁguration Utility

3-9

With Media Installed provides removable media support wherever the

drive(s) actually resides.

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 partition

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 Alternate CHS Mapping.

Note:

Neither of these options will have any effect 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.

Note:

After clearing the partitions and data, it is necessary to

reboot and clear memory or the old partitioning data will be

reused, thus nullifying the previous operation.

Spinup Delay (seconds) – This option allows the user to stagger

spinups 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 device 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 spinups to limit start-up current.

Please review the descriptions of each option below before changing any

values.

Sync Rate (MBytes/sec) – This option deﬁnes the maximum data

transfer rate the host adapter will attempt 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 will attempt to negotiate. The host adapter and a SCSI

device must agree to a width they can both handle. Only chips 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. This disconnect option frees the SCSI Bus

to allow other I/O processes. Additionally, it tells the host adapter whether

or not to allow a device to disconnect. Some devices run faster with

disconnects enabled (mostly newer devices), while some run faster with

disconnects disabled (mostly older devices).

3-12

Conﬁguring the LSIU40HVD

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. Because this provides a

safeguard by allowing the system to recover if an I/O operation fails, you

should always set the time-out to a value greater than zero.

Note:

A zero value allows unlimited time for an operation to

complete and could result in the system being hung-up.

Scan for Device at Boot Time – 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, you can speed up boot time by

changing this setting to no for all unused SCSI IDs.

Scan for SCSI Logical Units (LUNs) – Set this option to noif problems

arise with a device that responds to all LUNs whether they are occupied

or not. For example, if a SCSI device with multiple LUNs is present on

the 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 only.

Queue Tags – If the device driver has the capability, this option allows

the user to enable or disable the issuing of queue tags during I/O

requests.

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 Device – 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. Formatting will default the drive to

a 512-byte sector size even if the drive had previously been formatted to

another sector size.

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:

A.1 Physical Environment

This section discusses the physical, electrical, thermal, and safety

characteristics associated with the LSIU40HVD. The board is compliant

with the electromagnetic standards set by the FCC.

A.1.1 Physical Characteristics

The dimensions of the LSIU40HVD are 190 x 96.52 mm (7.50 x 3.80

inches). PCI connection is made through the edge connector J1. Internal

16-bit SCSI connection is made through the 68-pin high density

connectors J2 or J5. External SCSI connection is made through the

68-pin high density connectors J3 or J6. The J3 and J6 connectors

extend through the ISA/EISA bracket, which is attached to the face of the

connector outside of the cabinet where the LSIU40HVD is installed. The

bracket is a standard ISA type with a cutout to accommodate the

connectors. The J4 and J7 connectors are for connecting the computer’s

Busy-LED. It is a 4-pin, one-row right-angle header wired in parallel with

the onboard LED. The component height on the top and bottom of the

board follows the PCI speciﬁcation.

Technical Speciﬁcations

A.1.3 Thermal, Atmospheric Characteristics

The board is designed to operate in an environment deﬁned by the

following parameters:

•

Temperature range: 5–55 ˚C (dry bulb)

Relative humidity range: 5–90% noncondensing

Maximum dew point temperature: 32 ˚C

A.1.4 Electromagnetic Compliance

The board minimizes electromagnetic emissions, susceptibility, and the

effects of electromagnetic discharge. The board meets the requirements

of FCC and CISPR Class B limits and is marked with the FCC Self

Certiﬁcation logo. It also carries the CE mark.

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 ﬂammability rating. Because this board is

installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit.

Physical Environment

A-3

A.2 Operational Environment

The LSIU40HVD is designed for use in PCI computer systems with an

ISA/EISA bracket type. The LSI Logic SDMS software operates the

board, but the design of the board does not prevent the use of other

software.

A.2.1 The PCI Interface

The PCI interface operates as a 32-bit DMA bus master. The connection

is made through the 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 following tables show the signal assignments.

Note:

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