SCSI Card 2930U2 User’s Reference
Using SCSI and IDE (or EIDE) Peripherals
All Adaptec SCSI cards can coexist 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 is typically the boot drive. In this case, dis-
able the BIOS on the SCSI card (see
Advanced Configuration
Options
on page 20). If your computer supports BBS (BIOS Boot
Specification), both SCSI and non-SCSI disk drives can coexist
and you can specify which drive to boot from. Refer to your
computer documentation for more information.
You cannot connect an IDE peripheral to a SCSI card, or a SCSI
peripheral to an IDE card (controller).
Disable the BIOS on the SCSI card if no SCSI hard disk drives
are installed (see
Advanced Configuration Options
on page 20).
Replacing a Non-Adaptec SCSI Card with an
Adaptec SCSI Card
SCSI is standard, but how data is translated onto a hard disk
drive is not. Each SCSI card manufacturer uses its own transla-
tion schemes for writing data to a disk. To use a hard disk drive
previously connected to a non-Adaptec SCSI card, low-level
format the drive after connecting to the Adaptec SCSI card.
(See
Using SCSI Disk Utilities
on page 22.)
Caution:
A low-level format destroys all data on the drive.
Be sure to back up your data before performing a low-level
format.
