pages in the SCSI-2 specification. The SCSI-1 format

will not be implemented so this bit must be set to 1. It

is an

ILLEGAL REQUEST to have page parameters

while the PF bit is 0.

Save Parameters. Must be 0. If set, this bit instructs the

SuperLoader 3 to save all savable pages, and this is

not supported.
