- ----DU.ASM----
- OVERVIEW:
- Originally written to reconstruct erased directories,
- or directories where info was overlaid. Thus allows dumping,
- by group, track, sector, filename, etc. and patching. Allows
- ascii or hex scan of the disk. Maps the location of files
- on the disk by group. You should know the format of a CP/M
- disk if you're going to diddle with DU.
-
- USAGE:
- DU.ASM provides an overview of the file. DU has a
- built in help function ? which tells the format of all
- commands.
-
- DEPENDENCIES:
- "Standard CP/M 8" disks" - i.e. 77 tracks,
- directory at track 2. Standard CP/M scramble factor
- (but could be changed in the .ASM file) etc. It also works
- on such disks as Northstar CP/M 1.4 which the excellent
- Lifeboat BIOS make "look" like full sized disks in terms of
- sector/track etc.
