ADA access on VESA for DOS32bit with Alsys 5.1.3 or Metaware C

ADA access on VESA for DOS32bit with Alsys 5.1.3 or Metaware C

[Jean-Philippe]

Have you got a solution (old solution !) to allow an ADA application
running on DOS 32bit displaying in 1024 768 using VESA.

This application is in ADA  (350 000 source lines) with Alsys 5.1.3
which embedds PharLap runtime for the 32bit protected mode.

Thanks.

Try to adapt Jerry van Dijk' SVGA library (search pointer with dejanews).
You can find it in my PC_GRAPH.ZIP, page
 
  http://www.unine.ch/math/Personnel/Assistants/Gautier/Gaut_FTP.htm

It's for GNAT/DOS 3.07-3.10p (32-bit code).

My SVGA package (see my homepage) for GNAT supports either VESA 1.2
(bankswitched) or VBE 2.0 (linear frame buffer) displays in 256 colors
for 640x400 up to 1280x1024.

This package has been written to run under the DJGPP dpmi extender but
could also be made to work with the PharLap extender. There is little
dependence in the code on either GNAT or Ada95 specific features.
