good question well I never have flashed mine since I was a Quake3 freak at that time Quake3 really worked like a charm with those T&L drivers, it's bios didn't need recovery at all. 8)
Anyways I still have my trust Viper II OEM in my Mom's PC and Boxed next to my RA2 Voodoo5 PC
the AthlonXP 2700+ aka Sveta.
But norries on that site, it's nogt english but that site did have the most resources I could find about the Viper II Z200 and other Savage 2000 cards.
I do remember the Savage 2000 board carrying this beautifull Blue S3 SAVAGE 2000 logo:
that board had everything you needed for your Savage 2K really everything was there, now I can't seem to find that honorable board anmore ;(
oh I also came across this nice site too :
http://usuarios.lycos.es/todohardware/savage2k.htmAlso has a bios section
and also all the specs you need of the S3 Savage 2000 GPU:
