Compaq AlphaServer ES45 1B User Manual

Firmware 5-69
5.14.20 pk*0_fast
The pk*0_fast environment variable enables fast SCSI to perform in
either standard or fast mode.
If the system has at least one fast SCSI device, set the default controller speed
to fast SCSI (1). Devices on a controller that connects to both standard and fast
SCSI devices will perform at the appropriate rate for the device. If the system
has no fast SCSI devices, set the default controller speed to standard SCSI (0).
If a fast SCSI device is on a controller set to standard, it will perform in stan-
dard mode.
To list the controllers on your system, enter the show device command. SCSI
controllers begin with the letters “pk,” for example, pka0. The third letter is the
adapter ID for the specific SCSI controller. Replace the asterisk with the
adapter ID letter when entering the set pk*0_fast command.
The value of set pk*0_fast takes effect only after you reset the system by press-
ing the Reset button or by issuing the init command.
