- PROBE will tell you what version of CP/M or MP/M you are
- running, and display the I/O byte if appropriate. It then
- displays the addresses of the CCP, BDOS, and BIOS. The BIOS
- jump table will next be displayed including the extended BIOS
- calls for CP/M+, and XIOS calls if running MP/M. It then
- displays the disk parameter blocks (DPB's), disk parameter
- headers (DPH's), group size, total disk size, number of
- directory entries, space required for directory entries, total
- usable space on the disk, and the disk space allocation vectors
- for any selected drive (A: through P:).
-
- PROBE was written in 'c' to help decode the disk formats of
- a number of different machines to aid in transportability. It
- was inspired by BDLOC, TELL, ALLOC, and a number of other public
- domain CP/M utilities.
-
- My method of use of PROBE has been to move it to the target
- machine and run it after pressing a CTRL-P to get a hard copy
- print of the target machine's disk parameter blocks. Because of
- this modus operandi, I have not used any pretty screen stuff.
- You may wish to be prepared to hit the old control-S as it
- starts scrolling by. I have used the information gathered this
- way to write a "Uniform(tm)"-like utility (also in 'c') to
- change my disk parameter blocks to read/write a whole bunch of
- floppy formats. This works very nicely on my machine (Heath
- H-89/90 using the CDR soft-sectored controller), and I have
- plans to move it to Osborne and Kaypro, as well as certain
- others.
