[Openchrome-users] Memory size detection failed: using 16MB, system has 8MB

[Mark Huijgen]

Hi,

The company I work for manages lot of computers with the following VIA 
chip: VIA VT3122 (CLE266)-EPIA M/MII/....
All the bios'es have the video memory set to 8MB. The driver fails to 
detect this and defaults to 16MB. This of course gives some weird result 
on the screen.

I put in some debug lines around
     /* detect amount of installed ram */
in via_driver.c to print pScrn->videoRam and bMemSize, both are 0.

Is this something that can be fixed in the driver? Or is it a problem 
with the BIOS's of these computers?

Below are some lines of the Xorg.0.log, note that I hacked the driver to 
set the video memory to 8mb when detection fails. This hack gives a 
workable system. The driver is compiled from SVN this morning.

Regards,
Mark
