[colorforth] Success...my first boot screen

["t" <loveall@xxxxxxxxx>]

For a working example of a 32-bit implementation of flat real mode see my 4word
color forth
http://www.users.qwest.net/~loveall/binary/4word18.zip
with a slightly stronger version of round-robin multi-tasking, BIOS character
I/O and DOS file interface. No networking, but it runs on all X86 cpus from the
386 to PII, on DOS, Win 9x and NT DOS boxes.

Regards,
Terry Loveall
