Combining SCSI and Non-SCSI Devices

You can install the Adaptec SCSI Card 29160 in a computer that
already has a non-SCSI controller, such as an EIDE controller. How-
ever, you cannot cross-connect the disk drives and other devices:
SCSI devices must be connected to the Adaptec SCSI Card 29160,
EIDE devices must be connected to the EIDE controller, and so on.
When you install the Adaptec SCSI Card 29160 and SCSI disk drives
in a computer that boots from a non-SCSI disk drive, the computer
will continue to boot from the non-SCSI disk drive unless you
change the computer's CMOS configuration. You do not need to
change the configuration if you just want to use the SCSI drives for
additional file storage space.
If your computer's motherboard BIOS supports the BIOS Boot Spec-
ification (BBS) feature, you can select a different boot device without
much difficulty. (To determine if the motherboard BIOS supports
BBS, read the computer documentation or contact your mother-
board manufacturer.)
The following table shows what to do, after you physically install
the SCSI card and SCSI devices, to enable you to use different kinds
of disk drives in the same computer:
