Hi Shahar,
I'd like to try that.
The documentation of vgabios is not very specific about the tools needed to
compile it, but it makes a reference to a Turbo C 2.0, so i guess that's the
bcc 16bit compiler you mention in your email.
Would it work with one of the recent versions of borland's turbo C ? or I
need to find an ancient version of it?
AFAIK Turbo C is still DOS/Windos only (I haven't used it since many many
years ago). An then, I need to have an environment with both bcc and gcc..
I'll need cygwin then, which means a recent version of windows. And an
ancient DOS compiler. Nasty indeed.
