Field Name Description
PF Page Format. The Page Format bit indicates that the
data sent by the host after the MODE SELECT header
and block descriptors complies with the definition of
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.
SP Save Parameters. Must be 0. If set, this bit instructs the
SuperLoader to save all savable pages, and this is not
supported.
