SCSI Card 2940UW Pro User’s Reference
Using SCSI and IDE (or EIDE) Devices
■
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 and a SCSI hard disk, the
IDE hard disk is typically the boot disk. If your computer
supports BBS (BIOS Boot Specification), both SCSI and non-
SCSI disk drives can coexist and you can specify which hard
disk to boot from. Refer to your computer documentation for
more information.
■
You cannot connect an IDE device to a SCSI card, or a SCSI
device to an IDE card (controller).
■
Disable the BIOS on the SCSI card if no SCSI hard disks are
installed (see
Advanced Configuration Options
on page 18).
Replacing a Non-Adaptec SCSI Card with an
Adaptec SCSI Card
■
SCSI is standard, but how data is translated on to a hard disk is
not. Each SCSI card manufacturer uses its own translation
schemes for writing data to a hard disk. To use a hard disk
previously connected to a non-Adaptec SCSI card, low-level
format the hard disk after connecting to the Adaptec SCSI card.
(See
Using SCSI Disk Utilities
on page 20.)
Caution:
A low-level format destroys all data on the hard
disk. Be sure to back up your data before performing a low-
level format.
