IDE Devices & CMOS Setup
When you install a new hard disk drive its parameters will be
automatically detected by the BIOS and entered in the Standard
CMOS Setup section of the CMOS Setup utility if you use the
Optimum Settings, which automatically detect any new hard disk
drive. All other devices do not use drive parameters and will not
show up in the device list on this page.
Adding SCSI Devices
This section is a brief overview of adding SCSI devices to a
computer system based on this mainboard. Additional informa-
tion on SCSI and the support software is in text files supplied
with the SCSI support software on the Support Disk.
There are two SCSI connectors mounted on the mainboard, a
50-pin connector for Wide SCSI and a 68-pin connector for Ultra
Wide SCSI. The onboard SCSI controller supports both of them
and uses software that is provided on the Support Disk.
SCSI devices connect to the mainboard in a “daisy-chain”, that
is, in a series connected by cables between each device. If the
devices are internal, you connect devices with a ribbon cable that
has more than one device connector, such as the 50-pin Ultra
SCSI cable supplied with the mainboard.
SCSI devices can also be connected as external devices, in
which case individual external SCSI cables connect any devices
in the serial chain. You can connect external devices to this main-
board by connecting and external adapter to one of the onboard
SCSI ports. Such adapters provide an external SCSI port that
mounts in an expansion card slot opening. You then connect ex-
ternal SCSI devices to the external port. External SCSI port adapt-
ers can be purchased from a computer accessory vendor. You
must get an adapter specific to which SCSI connector you are
connecting to, either Wide SCSI or Ultra Wide SCSI.
