DOS Graphics 1024x768 24-bit colour Real Mode

Post by RetroMID » Wed, 06 Jul 2005 06:05:19


In order to be able to use mailslots for which I have real mode DOS
code that works, I need to have real mode DOS support (drivers or unit)
for 1024x768 graphics with 24-bit colour.

Can anyone help me please?

I am a musician/sculptor, not a real programmer but I can program in
Borland Pascal.

My work requires many DOS PCs all displaying graphics at the required
resolution which receive mailslot "commands" from other PCs using P
Scott Harris's HL_MAIL.

thanks v much for ur reply

i DO have svgabg55.zip

it seems to me that the color-depth at 1024x768 can not be higher than
15-bit

if it can go higher than that, please help me with a hint.

1. it depends on the version of these BGI drivers I think, the newest is
V3.00 afaik.

2. it depends on your graphics card and whether it is supported with
these vgi drivers. One mine is supported with 800x600x24 but only has
2 MB RAM so this is fair, the others I didn't try. But all VESA
compatible ones should work afaik.

3. did you already run the supplied bgidemo program? There you can try
out all drivers without great fuzz.

Hi,
Go to this site and download GraphUp (formerly NGraph) by Harry Lotz &
Jutta - great replacement for the Borland graph unit - very powerful -
reqires a few changes to initgraph(much simpler) - supports just about
every gfx mode you can think of providing you have a Vesa compatible
Gfx card. 1024 x 768 no probelm - goes up to about 1800 x 1600. Works
in real mode - a protected/win mode is being worked on - free trial - a
few euros to buy - this is a great unit. English translation from
German (by me) a little shaky but you should be able to figure it out!
