Variable Attributes Description
pk*0_fast
(continued)
If a controller is set to standard SCSI mode, both
standard and fast SCSI devices will perform in
standard mode.
1—Sets the default speed for devices on the
controller to fast SCSI mode.
Devices on a controller that connect to both
standard and Fast SCSI devices will automatically
perform at the appropriate rate for the device,
either fast or standard mode.
pk*0_host_id NV Sets the controller host bus node ID to a value
between 0 and 7.
0 to 7—Assigns bus node ID for specified host
adapter.
pk*0_soft_term NV Enables or disables SCSI terminators for optional
SCSI controllers. This environment variable
applies to systems using the QLogic SCSI
controller, though it does not affect the onboard
controller.
The QLogic SCSI controller implements the 16-
bit wide SCSI bus. The QLogic module has two
terminators, one for the 8 low bits and one for the
high 8 bits. There are five possible values:
off—Turns off both low 8 bits and high 8 bits.
low—Turns on low 8 bits and turns off high 8
bits.
high—Turns on high 8 bits and turns off low 8
bits.
on—Turns on both low 8 bits and high 8 bits.
diff—Places the bus in differential mode.
tga_sync_green NV Sets the location of the SYNC signal generated by
the ZLXp-E PCI graphics accelerator (PBXGA).
