Format description

diskdef name				format definition
  seclen n				128,256,512,1024,.. Sector length
  tracks n				1.. Number of tracks
  sectrk n				1.. Sectors per track
  blocksize n				1024,2048,4096,8192,16384 Block size
  maxdir n				1.. Number of directory entries
  skew n				0.. Logical sector skew
  skewtab r1,r2,r3,...			skew table
  boottrk n				Number of system tracks
  offset n | nK | nM | nT		n Byte|n Kilobyte|n Megabyte|n Tracks
  logicalextents			Logical extents per physical extent
  os 2.2 | 3 | isx | p2dos | zsys	
  libdsk:format name			pcw720, cpcsys
end
 

Berechnungen:

size := (secLength*sectrk*(tracks-boottrk))/blksiz;
if (extents==0) extents := ((size>=256 ? 8 : 16)*blksiz)/16384; if (extents==0) extents := 1;
Allocatabledatablocks := size-(maxdir*32+blksiz-1)/blksiz);

posix:
physical pos := ((sector+track*sectrk)*secLength)+offset;
  
win32c:
SetFilePointer := ((sector+track*sectrk)*secLength)+offset; 

libdisk:
physical sector := track*sectrk + sector + offset/secLength;

PDCurses installieren, d:\devtools\MinGW\include\curses.h heißt schon richtig?

cd d:\devtools\MinGW\lib\
copy libpdcurses.a libcurses.a

tar zxvf cpmtools-2.13.tar.gz
cd cpmtools-2.13
./configure --with-diskdefs="" --with-defformat="default" --with-libdsk=/local/
make
make -i install
strip /local/bin/*.exe

tar zxvf cpmtools-2.18.tar.gz
cd cpmtools-2.18

es gibt Compiler-Probleme mit den mitgelieferten getopt-Daten, deshalb
	- in Makefile.in "getopt$(OBJEXT) getopt1$(OBJEXT) " überall löschen
	- leere Datei getopt_.h anlegen (oder vorhandene leeren)

./configure --with-diskdefs="" --with-defformat="default" --with-libdsk=/local/
make
strip *.exe
make -i install
