ALL LAPTOP USERS READ THIS : Currently there is NO WAY to support widescreen without rendering your main LCD useless (it will just stay black and won't display anything at all). If you don't care about your main LCD open a new thread and ask for a patched bios. Otherwise use Linux which supports widescreen without the need of a special video bios version. Or if you don't want to use Linux: don't buy a widescreen LCD!

WARNING : With a bios patched for widescreen you will not be able to use: DVI, TV-OUT or (on laptops) LCD. The video bios is missing support for those ports/devices and there's nothing we can currently do about that!

A patched bios with a recent SIS video bios fixes issues with widescreen resolutions like 1440x900 or 1680x1050 (Official SIS FAQ regarding this issue).

Follow these steps:
1. Install the .inf file for your monitor
2. Install the latest SIS VGA driver

AGP(GART) driver (1.21, ~3.5MB)
needed for ALL (!!!) SIS chipsets w/ and w/o integrated VGA

SIS630/730 (UniVGA 2.09, ~43MB):
-> Sadly no widescreen support for these VGA chipsets in Windows

SIS65x/740 (UniVGA3 3.73, ~16MB):

SIS66x/76x & 67x/741 (UniVGA3 3.93, ~18MB)
Windows Vista:
SIS67x/771 (UniVGA5 5.25, ~15MB)
->The driver below might also work on Windows Vista

Windows 7:
SIS67x/771 (UniVGA5 5.29, ~15MB)

if your problems still persists:
3. check if there's a patched bios available on our << download page >>.
ATTENTION! : Make sure you properly identified your motherboard; a patched Bios for a wrong board (or motherboard revision) may render your board unuseable !! You need to know your motherboard manufacturer, motherboard name or model number and sometimes the motherboard revision number. Make also sure you don't try to flash a patched retail Bios onto an OEM version of this board and vice versa. If you're not sure about your motherboard please ask in the Forum !

4. If there's no patched bios for your mainboard: request one in the forum! MAKE SURE TO INCLUDE A DIRECT LINK TO YOUR MAINBOARD BIOS.

Internal revision notes:
