Rép. : Re: [K12OSN] k12ltsp 5beta2 details

Here's my 2 cents.
We have ASUS p4p800-VM machines that use i810 style video card.
We had to modify the BIOS settings for the video ram. Here are the values that are set:
Onboard video memory = Enabled, 8 MB
Graphics Aperture size = 64 MB
Hope this helps.

I had tested as low as 3072. 4096 & 8192 worked fine as well, of course.

I didn't try 2048.
