How do I change the display resolution to 1280x1024 and 24-bit colours?

Highly OS specific problem.

DOS or none:

- VESA (semi-difficult)
- Native card access (ISA/PCI/AGP) (very difficult)

DEXOS:

VESA provided by DEXOS (very easy ?) when DEXOS bugs fixed

Windoze:

Win-API

Linux:

Lin-API ???

MENUetOS:

See appropriate subforum

You can not post remarks like this, When the code runs fine with its own boot loader, fine under MS-Dos, fine under some other Dos, but not under FreeDos.
The problem is with FreeDos, you need to get your facts RIGHT first
