Hi guys,
Just got a 22" widescreen for my parents machine, which unfortunately has the crippled SiS 650 IGP. I flashed the latest official Asus BIOS, 1010 - this brings the VBIOS to 1.15.26 - not recent enough for widescreen support. The direct download link is:

I tried to hack in the more recent 2.30.01 VBIOS - fiddled with all the Asus specific checksums and got the Asus windows flasher to accept it. The PC bricked on booting, claiming invalid checksum. I managed to flash back to 1010 through the boot block code (which luckily wasn't crippled.)
I suspect that since the compressed portion of the BIOS is shorter (VBIOS 2.30.01 is 32K while 1.15.26 is 48K,) some entry point into the compressed section changed and the BIOS tanked. Another weird thing - there is a second copy of the compressed VBIOS towards the end of BIOS, right in the middle of the uncompressed pure binary section.
Anyway, if anyone has any ideas or could give me a hand, it would be much appreciated.

SIS 650 - Asus P4S8L - Trying to update VBIOS
Got it figured out - I finally found a copy of the Asus specific CBROM in the BNTBTC collection. I managed to replace the VBIOS in the compressed section - apparently the VBIOS in the bootblock is only used during the boot sequence. The windows driver now reports VBIOS version 2.30.01 and allows all the widescreen resolutions. Woohoo

Hi,
can you please send me your patch and a littile bit of explanation.
I'm not that great of a Bios Flasher
I really need it, because I have a terrible pain in my eyes at the end of the day...
