vesa mode

2009-07-10 Thread Hans-J. Ullrich
Hi all, 

mybe someone can explain this: I am starting my debian system with the 
parameter vga=791 (to switch into vesa mode)

Sometimes the computer (AMI-BIOS) does not do it correctly (stays in 640x480 
then), but with a reset everything starts perfectly. What is the reason for 
this behaviour?

On my amd64-system (Phoenix BIOS) this behaviour NEVER appeared. 

Is the reason for this the setting VGA initialisation ? In my BIOS it is set 
to AGP as I am using an AGP-Graphicscard. Or is it just a timing problem?

Would be nice, if someone could give me some background information.


Cheers

Hans

VESA support is a function of your video card, not your motherboard.
The video bios is responsible for it, not your motherboard bios.
