Anyone here that has an original VGA card? The ones with 256kb memory and not SVGA stuff.
I want to get the bios from one of those thingies and see if i can run it on dosbox and use it for reference in getting the bios support improved a bit. Or perhaps stiletto knows someone that has one.
I'll try to work my magic. So far, all I've discovered is that the chipset is named "IBM VGA256C" 🙁

It might be IBM PN#1887743 or PN#1887744 - "IBM PS/2 Display Adapter". Use Google.
Edit: It definitely is.

AFAIK premiered in IBM Personal System/2 Model 30. 😀

Looks like good places to ask "WTB" are:
comp.sys.ibm.ps2.hardware
comp.sys.ibm.pc.classic
Final shot from me (for today, at least):
This guy (http://www.compu-d.com) had some (http://209.196.190.156/1/ibmliquid.htm) at some point. I bet they're all gone now, but it never hurts to try...
BTW - The guy's a known spammer (http://www.studio42.com/kill-the-spam/1999/re … s/compu-d.shtml) so I'm not sure how far you could trust him. Lots of odd stuff comes up when you search for "Compu-D"...

Ah well just have to find someone that has a machine running with one and wants to run a little tool and send me the file it generates. You'd think someone would still have an old machine running with one 😀
I'll go check some usenet places too.

Yeah saw that but it's a cheap vga bios, missing a lot of functions needed by old games.
Then when you figure out stuff, submit to them, kay? 😀
BTW - you can code a program to dump the BIOS w/o seeing or knowing the card? WTF?

Anyhow, I'll go give Trixter a shout, see what he knows...

Yeah you can just save the vga bios by writing a 32kb block of memory at a certain address in a file.Would be at 0xC000:0000, so you can easily get it dumped.
Dumping the vid bios is simple. It's almost always at the same meory location on all vid cards.

Got one from some guy on usenet, now just have to get it up and running in dosbox. Really wonder if my vga emulation is good enough to run it 😀
I can think of a place you could get more, probably...ever been to hospitals? Their technology is always at least 10 years behind the time (for example, the hospital my father works at still runs Compaq desktop (not minitower) Pentium 75MHz on Windows 95A, and they still have old green monochrome monitors for looking up patient stats).
Yes, it’s my fault.
Well a pentium 75 still has a better vidcard than an original ibm vga card. Ah well bios image actually seems to start up already, some detection shit left to fix and i think it would run fine.
Sounds great. Looking forward to it 😉
Yes, it’s my fault.

Good for you! Let me know how it works out.
BTW - Get some of the BIOS Roms for M.E.S.S. (http://www.mess.org). Among the BIOSes they have are (in the XTVGA driver) an ET4000 bios. 😀

hehe i'll give them a try too, bios imagine works fine now though, still some bugs left in my own bios i see, since some games seem to have correct colors now and text is being displayed.
Ah well let's look at some disassembly and see how the shit works 😀
Wow, you can actually read assembly? You are a god. (Or just really, really old 😉)
Yes, it’s my fault.
