DOS ain't dead - NOKEYB Release 1

NOKEYB Release 1 (Announce)

Hi!

I recently acquired two Highscreen Handy Organizer palmtop PCs and wondered, whether and how it would be possible to free some precious memory by replacing KEYB.COM. But on the Highscreen Handy Organizer, files C:\AUTOEXEC.BAT and D:\DOS\KEYB.COM are in read-only memory (ROM), which prevents modification.

I took my 2002 FIX8X14 device driver and created NOKEYB. It works by intercepting DOS function 4Bh 'load and execute'.

For those w/o a Highscreen Handy Organizer (a.k.a. Tidalwave PS-1000 or Zeos Pocket PC) there is probably little to no use, but maybe you can use the source code (for NASM) as another skeleton for your own drivers.
