windows 98 can only address to 256mb of ram

"Minimum graphic requirement:8MB 3D video card "

and

"Video card: Cirrus Logic 5446 PCI 1MB."

Thats your problem.
You are not going to be running any 3d games with that card.

I just setup a "ghetto" gaming rig as my friends call it.  Specs:

Amd 1000mhz slot A processor
*gateway POS motherboard*
256mb ram
30gig hard drive
windows 2000 pro
Voodoo 5500 in the agp slot
and a pair of voodoo 2s in sli.

i THINK i have everything setup right, my video come out of the 5500, into the voodoo 2 #1 then through voodoo2 #2 and to my monitor.

I also used the drivers on this site.

But the issue is, i dont think the voodoo 2's are working.  If i start  unreal tournament with glide support everything works, but i dont know if the voodoo2's are doing anything.

And if I open serious sam (#1) in "Serious Sam - 3Dfx Voodoo2 compatibility" it never loads, the screen turns black or green ad it crashes.

Is there something super simple i'm overlooking or what?

thanks for the help - in advance.
