Using the Adaptec SCSI Card 39160 and SCSI Devices
Combining SCSI and Non-SCSI Devices
You can install the Adaptec SCSI Card 39160 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 39160, 
EIDE devices must be connected to the EIDE controller, and so on.
When you install the Adaptec SCSI Card 39160 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 use different kinds of disk drives 
in the same computer:
Does computer BIOS 
support BBS?
Want computer to boot 
from SCSI drive?
Then do this:

mentation). You will not be able to 
use the non-SCSI drive(s) at all
 
when you boot from the SCSI 
drive.
