Video Mode 13h and Mode X in C

[Krish Bashwari]

Hello

I am seeking the best way (speed and portability) to program
mode 13h (320 x 200 256 colors), and mode X.

I am using Borland's Turbo C++ ver 3.0 for MS DOS.
With Borland product, I can not find a BGI driver for this mode.
I know there are built in support for the other VGA modes
(640 x 200 x 16 colors), (640 x 350 x 16 colors).. but I am not
interested in those.

What are your suggestions. Do I have to write my own C and ASM routines
to do Mode 13h and Mode X? I could not find an updated BGI driver
from Borland.

Secondly, I am planning to port all of the MS DOS code to Windows.
I would appreciate some code design tips to reduce the amount of
work rewriting video code from DOS to Windows.

I know MS C compiler has Mode 13h support built in, but I do not
have MS C compiler. By the way, is there Mode X support in MS C compiler.

Thank You

You're in luck, the following comes with a 320x200 BGI driver, see:

This looks great, unfortunately I don't see any links to the files in the
file listing! Any pointers.

Also still need tips for portable coding to help port video code from DOS
to Windows.

Thank You.

You're more likely to find people who know about that sort of thing in a
group for DOS or Windows programming. I don't have any pointers, but a
search should find some suitable places; I know they exist.
