Scanners; Installing Multiple Scsi Cards; Using Scsi And Ide (Or Eide) Peripherals - Adaptec AVA-1505A User Reference Manual

SCSI Card 1505 User's Reference
The SCSI Card 1505 does not support the boot option. To boot
your system, a bootable hard disk drive must already be
installed on a different SCSI card or IDE card.
If both SCSI and non-SCSI (for example, IDE) disk drives are
installed, then the non-SCSI disk drive is always the boot drive.

Scanners

You may need to install the scanner manufacturer's propri-
etary software drivers. See your scanner's documentation for
details.

Installing Multiple SCSI Cards

You can install multiple SCSI cards in your computer; you are
limited only by the available system resources (for example,
IRQ settings, I/O port addresses, BIOS addresses, and so forth)
not used by other cards installed in your computer.
Each SCSI card you install forms a separate SCSI bus with a
different set of SCSI peripherals. SCSI IDs can be reused as
long as the ID is assigned to a peripheral on a different SCSI
bus (for example, each SCSI card can have a peripheral with
SCSI ID 2).
If you have two or more SCSI cards, enable the BIOS on the boot
SCSI card only; disable the BIOS on the remaining SCSI cards.

Using SCSI and IDE (or EIDE) Peripherals

All Adaptec SCSI cards can co-exist with another controller
(IDE, EIDE, RLL, etc.) installed in the computer.
If you have both an IDE hard disk drive and a SCSI hard disk
drive, the IDE drive will always be the boot drive.
You cannot connect an IDE peripheral to a SCSI card, or a SCSI
peripheral to an IDE card (controller).
