NOTES:

1. Fully supported and temporary fields are underlined. Unsupported and ignored

fields are not underlined. The PS bit is underlined, meaning it will be set on a
MODE SENSE command, since the page is savable.

2. Bytes 8 to 11 are returned only if the device operating definition is

SCSI-3.
