both

the

host

adapters

are

AHA-1542s (e.g., both have floppy

controllers), one of the floppy controllers should

be disabled

removing the

floppy enable jumper.

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

must

different on the two host adapters. The Interrupt channel can

changed by changing jumpers

the AHA-1540/1542. With

the

AHA-

1640/1740/1744, configuration options

are

selected via software, thus

eliminating the need to set jumpers. The AHA-I640 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

be assumed

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

available alternatives, any

which can

selected for the flrst or second host

adapter.

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

must

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

AHA-1540/1542.

The

appropriate configuration software must

run for the

AHA-1640/1740/1744. When configuring the AHA-I640/1740/1744 host

adapters, the default DMA channel will

be 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 adapters.

- The BIOS on

least one

the AHA-1540/1542/1640 host adapters should

be disabled. With the AHA-1540/1542/1640 host adapters, only one host

adapter in the system should have its BIOS enabled. The BIOS

every

AHA-1740/1744 in the system should always

The

BIOS

address for the AHA-1740/1744 is selected using the appropriate

EISA

configuration software.

booting is desired from the SCSI disk drive, the

drive SCSI ID must be 0 and the BIOS must

enabled on its AHA-

1540/1542/1640/1740/1744 host adapter. The port address

the host adapter

with the booting SCSI drive should

set to 330H.

you're

not

booting

from SCSI, you can disable the BIOS on all your AHA-1540/1542/1640 host

adapters. Again, don't disable the BIOS on the AHA-1740/1744, even

not

booting from a SCSI disk drive.
