Description
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.
Save Parameters. Must be 0. If set, this bit instructs the drive to save
all savable pages, and this is not supported on the tape drive.
