NAME

diskdefs - CP/M disk and file system format definitions

DESCRIPTION

The diskdefs file contains CP/M format descriptions, because CP/M in general does not store those in the file system and there are no standards of any kind.

A diskdefs file consists of one or more entries of the format:

diskdef name
  seclen size
  tracks count
  sectrk count
  blocksize size
  maxdir count
  [dirblks count]
  boottrk number
  [skew number]
  [skewtab sector[,sector]...]
  [os 2.2|3|isx|p2dos|zsys]
  [offset size]
  [logicalextents count]
  [libdsk:format name]
end

skew and skewtab must only be used exclusively.

Comments are marked with a leading hash or semicolon and extend to the end of the line.

It is possible to reserve space after the directory beyond maxdir using an inflated DPB ALV0. If the format makes use of that, dirblks must be set.
