I have flashed the BIOS and I can switch to 1680 x 1050. However, whenever I restart the computer, XP will switch the resolution and I have to manually switch it back to 1680 x 1050. Anyone has encountered the same problem? How can I fix it?
Download the latest Univga3 VGA drivers from www.sis.com
Deinstall your current VGA drivers and reboot. Now install the latest drivers and try again.
