Ah ok that makes sense.

It's no big secret!

We have this version:
http://www.vogonsdrivers.com/getfile.php?fileid=326
I am no longer sure of its origins other than smf found it online and shared it December 2011, swaaye uploaded it here 02/2012. Surely both came from the same source. Originally titled db019b.zip.

There's something else, I'm looking into it.

Anyways, I made sure VGAMuseum.info was notified in 2012, and they host a copy now in their labyrinthine installation.

(warning: vgamuseum hosts some video BIOSes but no work is done to ensure that they were dumped properly or completely, as said on its main page)

In general, VGAMuseum.info has an archive of anything of interest recently on the GPU/CRTC/etc. video documentation front. Some nice ongoing collaboration between myself and vlask, sparked by some discussion or at VOGONS.

As for S3 documents in general:

DatasheetArchive scanned a bunch as part of some big S3 document cache they acquired.
http://www.datasheetarchive.com/%22s3%20incorporated%22-datasheet.html

Or else you can occasionally stumble over some with this Google search:
https://www.google.com/search?num=100&safe=off&q=%22S3+Incorporated%22+%22Santa+Clara%22+filetype%3Apdf

Bitsavers has also been working on scanning the occasional S3 manual and will no doubt acquire these for a better-than-DatasheetArchive rescan at some point.

Fixed a silly bug that resulted in video modes using more than 1MB of VRAM to not be completely rendered.

This place is cool i've been here a number of times. Most of the Video BIOS dumps are probably fine they do have internal checksums that BIOS checks for and fails to post if it's bad. As for being incomplete Usually it would just be 00 fill padding at the end and if not BIOS will fail to post. But yea it's generally not a good idea to flash BIOS's from unofficial sources.

Good work. Most of issues is introduced due to a fact all was in one driver and then one change affected all, and those are different machines. Also it's much better now since things are separated for maintenance point of view.

I'm trying to hookup a Voodoo 1 in at586 i based changes on funkball.c. I think i'm close to getting it compiled just can't figure out where the remaining bits of code should go.
http://mamedev.org/source/src/mame/drivers/funkball.c.html

I'm pretty sure even if it compiles it won't display anything. But i want to see if at586 is stable enough to install the drivers and what the performance would be like. changed at.c is in the link below if anyone can give me some tips.
