Adaptec SCSI Card 29160N User’s Reference
Using SCSI and EIDE Devices
■
All Adaptec SCSI cards can coexist with another controller
(EIDE, RLL, etc.) installed in the computer.
■
If you have both an EIDE hard disk drive and a SCSI hard disk
drive, the EIDE drive is typically the boot drive. In this case,
disable the BIOS on the SCSI card (see
Advanced Configuration
Options
on page 22). If your computer supports BBS, both SCSI
and non-SCSI disk drives can coexist and you can specify
which drive to boot from. Refer to your computer documenta-
tion for more information.
■
You cannot connect an EIDE device to a SCSI card, or a SCSI
device to an EIDE card (controller).
■
Disable the BIOS on the SCSI card if no SCSI hard disk drives
are installed (see
Advanced Configuration Options
on page 22).
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 translation schemes
for writing data to a disk. To use a hard disk drive that was previ-
ously connected to a non-Adaptec SCSI card, low-level format the
drive after connecting it to the Adaptec SCSI card. (See
Using SCSI
Disk Utilities
on page 24.)
Caution:
A low-level format destroys all data on the drive.
Be sure to back up your data before performing a low-level
format.
