both

the host adapters are

AHA-l542s

(e.g., both have floppy

controllers), one

the floppy controllers should

disabled by removing the

floppy enable jumper.

- The Interrupt Channels (referred to as Interrupt Level with the AHA-I640)

must be different on the two host adapters. The Interrupt channel can be

changed by changing jumpers on the

AHA-l

540/1542. With the AHA-

1640/1740/1744, configuration options are selected via software, thus

eliminating the need to set jumpers. The AHA-1640 is configured using the

microchannel reference diskette. The AHA-1740/1744 are configured using

the EISA configuration software. Both

these software configuration

programs are designed to eliminate conflicts. When configuring the AHA-

1640/1740/1744 host adapters, the default Interrupt Channel will

assumed

by the configuration software. The configuration software will also list the

available alternatives, any

which can be selected for the first or second host

adapter.

- The DMA Channels (referred to as Arbitration level with the AHA-I640)

must be different on the two host adapters. Jumpers must be changed on the

AHA-l540/1542. The appropriate configuration software must

run for the

AHA-I640/1740/1744. When configuring the AHA-I640/1740/1744 host

adapters, the default DMA channel will

assumed by the configuration

software. The configuration software will also list the available alternatives,

any

which can

selected for the first

second host adapter.

- For the AHA-l540/42/1640, only one host adapter should have its BIOS

enabled.

booting from a SCSI drive is desired, the boot drive must reside

SCSI ID 0 on the host adapter with the BIOS enabled.

you are not booting

from SCSI, you should disable the BIOS ROMs on all adapters in the

system. Note: AHA-l540s with BIOS enabled must

be jumpered to port ID

340H.

- For the AHA-1740/1744, all BIOS ROMs should be enabled.

booting from

a SCSI device is desired, the boot drive should reside at the lowest SCSI ID

on the AHA-1740/1744 with the lowest BIOS address. The BIOS address for

the AHA-1740/1744 can

selected using the appropriate EISA configuration

software.

the AHA-1740/1744 BIOS is disabled, the default values for the

SCSI configuration will

used, and not the values selected in the EISA

setup activity.
