SCSI Device IDs
Each SCSI connector can support up to seven SCSI devices.
Each SCSI device in the chain must have a unique identification
number to identify itself to the controller. You set the ID number
on the device hardware. There are various ways to do this so you
will need to consult the manual for any device you want to in-
stall for instructions on how to set the ID for the device.
The SCSI controller on the mainboard has an ID number, 0
(zero), so the available device ID numbers are 1 through 7 for the
Wide SCSI. SCSI-2 chain and 1 through 15 for the Ultra Wide
SCSI-3 chain.
SCSI Termination
The SCSI chain must be “terminated” at each end. The con-
nector on the mainboard is permanently terminated and there
constitutes one end of the chain. The last device in the chain,
whether it is internal or external, must also be terminated. SCSI
devices use various termination methods, so you will need to
consult the manual for the last device in the chain to see how to
terminate it.
If you connect internal SCSI devices, the device connected to
the end of the ribbon cable is the last device and must be termi-
nated. In an external chain, the device at the end must be termi-
nated. All devices in-between the mainboard and the last device
must not be terminated.
Installing an AGP Card
An AGP display card installs in the AGP slot on the main-
board and secures to the system case at the matching expansion
slot opening. Any AGP card will require Operating System sup-
port, which will be implemented in Windows 98 and later ver-
sions of Microsoft Windows.
Review the card documentation for any additional installa-
tion instructions.
