Where there are multiple adapters, the AutoSCSI-based adapter with the

highest BIOS address controls the process of reading data from other

adapters for configuration information. 

 will also display config-

uration information from earlier 

 host adapters.

Table 3-1. Summary of Configuration Field Descriptions

Option

Description

Adapter 

Port

 Port

This field shows the base address of the registers the host uses
to communicate with the host adapter. Each board within the
same host system must have a unique 

 port address to pre-

vent hardware conflicts. On PCI adapters, the host system’s

BIOS assigns the 

 port address during the boot sequence.

Each board within the same host system must have a unique

 port address to prevent hardware conflicts.

This field shows the PCI 

 port address assigned to the host

adapter by the PCI motherboard BIOS.

Adapter Type

This field identifies the model of the 

 host adapter.

 Summary of Configuration Field Descriptions (Continued)

Option

BIOS Address

Description

This field displays the SCSI adapter BIOS starting address in
host memory. Where multiple adapters are installed, the primary
adapter must have BIOS enabled. It is suggested that the BIOS
on the remaining adapters be disabled but it is not required as

long as you ensure that the BIOS addresses don’t conflict.

Interrupt
Channel

This field shows the hardware interrupt line (IRQ) number that
the adapter uses to generate interrupts to the host. The adapter

issues an interrupt whenever it requests attention from the host.
On PCI adapters, the host system’s BIOS assigns the 

 value.

DMA Channel

This field does not apply to this product.

DMA Xfer Rate

This field does not apply to this product.

Adapter ID

This field displays the SCSI ID of the adapter on the SCSI bus.
There are sixteen SCSI 

 (O-15) on a wide SCSI bus. To

change this value, use the option on the 

Configure Adapter

screen.

SCSI Parity

This field indicates whether parity on the SCSI bus is turned on

or not. You may use the 

Configure 

 option to turn

the SCSI parity detection on or off.

Low Byte Term

These fields indicate whether the adapter’s termination is turned

on or not. SCSI devices are daisy-chained together and a 

High 

 is required at each end of the chain. To determine your ter-

mination requirements, see “Terminating SCSI Devices” in
Section 2. To change this value, use the options on the 

Configure

Adapter 

screen.

DOS Space 

This field displays whether this option is turned on or off. How
this value is set depends on DOS size requirements and the boot

requirements of other operating systems. See the detailed de-

scription of this option under “Advanced Configuration” later in
this section.

Firmware

This field shows the host adapter’s 

 firmware revision

Revision

level.

BIOS Revision

This field displays the revision level of the 

 BIOS.

Select Adapter

Where multiple adapters are installed, use this option to select the adapter

to be configured. When you select this option, you will see a display listing

all the adapters in the system. Select the desired adapter by using the Up

or Down arrow keys. Note that the current adapter is indicated by an as-

terisk. It is also always displayed at the bottom of the screen.
