These two progs come from the May '86 issue of PC Tech
Journal in an article, written by Glenn F. Roberts, called
"Finding Disk Parameters". The article gives a good overview
of the DOS disk structure, including: the boot record, the file
allocation table (FAT), and root directory. The progs show use
of (yet another) undocumented DOS function, 32H, to determine
the FAT's size and location.
An interesting outcome of this for me was that if I
turned off optimization (-Od), as Microsoft recommends for
debugging with Codeview, the bloody progs don't work! Compile
normally and everything is fine. You pay your money, and you
take your chances...
