;======= Hard Disk Parameter Blocks =======

; The B/P BIOS DPB's contain prefix information that provide data on the
; logical format.  This table contains only DPB Data on Hard Disk Partitions.
; See DPB.LIB for definitions of bit equates used in all DPB files.

; NOTE: For simplicity, the code always assumes a logical 16 512-byte sectors
;	per track for SCSI interface.  Translate the actual 17 or 18 sectors
;	to an increased track count of 16 sector tracks.

;.....
; Format Type Byte 0  (Fixed Disk Subset)
; ------------------
; D D D D D D D D
; 7 6 5 4 3 2 1 0
; | | | | | +-+-+----- Disk Size 000 = Fixed Disk, remainder unused
; +-+-+-+-+----------- (unused)

; All DPBs use the equate:  FIXDSK  EQU  00000000B  from DPB.LIB

; Format Type Byte 1  (Fixed Disk Subset)
; ------------------
; D D D D D D D D
; 7 6 5 4 3 2 1 0
; | | | | | +-+-+----- Sector Size: 010 = 512 bytes assumed in driver
; | | +-+-+----------- Allocation Size: 000=1K, 001=2K, 010=4K, 011=8K, 100=16K
; | +----------------- (reserved)
; +------------------- 1 = High Speed.  (0 Not Used)

; Information in this byte is not used in the SCSI driver, but is simply
; maintained for future use and compatibility with other DPB access routines.

; NOTE: No Skew Table is needed since Hard Disk Format is locked
