; 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, BPBIOS always assumes a logical 16 512-byte
|
||
; sectors (64 128 byte records) per track for hard disks.
|
||
; One must therefore translate the actual number of sectors
|
||
; to a track count of 16 sectors per track.

||
;.....
|
||
; Currently, BPBIOS supports 2 memory drive devices and 3 physical hard
|
||
; drive like devices. BPBIOS can support seven but unfortunately
|
||
; BPCNFG only supports 3 hard drive like devices and the source
|
||
; code is not available, so menu 4 is meaningless. Devices
|
||
; include IDE Hard drives (16 bit), USB and SD card drives. CF
|
||
; cards can connect to both 8 and 16 bit IDE interfaces. Note
|
||
; that the RAM and ROM drives are handled separately. A default
|
||
; system configuration consists of two Floppy drives, an IDE drive
|
||
; and an SD drive. The IDE drive is allocated eight 8 MB slices
|
||
; while the SD drive will have four 8 MB slices. For SIMH, the
|
||
; IDE drive is replaced by SIMH HDSK0 with eight slices and the SD
|
||
; drive with SIMH HDSK1 with 4 slices. The configuration
|
||
; and/or mix of drives can be altered at any time by using BPCNFG
|
||
; Manually or by editting the appropriate .CNF file. The SD card
|
||
; could replaced by the USB for example,
|
||
;
|
||
; Starting with ver 2.8 of HBIOS, devices are discovered at boot
|
||
; time and assigned device numbers. Since devices are tested in
|
||
; a certain order, the device numbers are somewhat predictably
|
||
; assigned. Memory drives are discovered first. IDE drives are
|
||
; discovered next so that IDE Hard drives including CF cards are
|
||
; assigned device 2 and device 3 if a slave drive is supported by
|
||
; the interface. Next comes the SD drive and is assigned device 3
|
||
; or 4 depending on the whether there is an ide slave drive.
|
||
; USB drive is assigned device 4 or 5. For SIMH HDSK0 is device 0
|
||
; and HDSK1 is device 1. Memory drives are now handled as LBA
|
||
; devices, ie like hard drives.
|
||
;
|
||
; The following non-memory drive capacities and configurations used for
|
||
; the SIMH, SD and IDE drives: Track geometry is 16 512 byte sectors.
|
||
; A slice is exactly 64 tracks, with 1 of the 64 tracks as a system
|
||
; track. There are 1024 directory entries per slice. If all partitions
|
||
; are not physically present, the missing partitions can be disabled in
|
||
; the BPBCNFG configuration file or by hand. Note that HBIOS uses LBA,
|
||
; Logical Block Addressing, for non-floppy drives.
|
||
;
|
||
; For SBC V1,2, ZETA, MARK IV and N8, the following non-memory partitions
|
||
; are available:
|

|
