VBIOS update for an SIS650 board (Sony Vaio PCV-W20)

[someguynamedjohn]

I was just wondering if there was a VBIOS update for a Vaio PCV-W20. I followed the FAQ and installed the AGP driver, then the latest Uni-driver from SIS and the computer simply locks up whenever I try to install the driver. I can't install the official Sony driver because I accidentally cleared the OEM DMI strings...

The link to the BIOS file is:
ftp://download.sony.com/US/pc/AW-A10020801AN.EXE

But it's all wrapped up in a setup file. I've extracted the relevant files and put them here:

I ran BIOS agent plus and this is what it told me:

please make a backup of your current bios and upload the image (in an archive ofcourse) somewhere.
there's no way i can use those Sony/HP/Compaq/FujitsuSiemens installers. they simply won't unpack or start on my machine.

oh, wait. i6comp makes it possible :) get the patched bios from our download site. please report back with the results.

oh...wait...the Sony PCV-W20 uses its own build in display, doesn't it? if you flash the patched bios the display will stay black and won't work anymore. please read the sticky message in this section.
