Make sure it isn't sharing an IRQ with another device. I had problems in the past with my TNT wanting to use IRQ15 for some stupid reason. IIRC I was able to mess with the BIOS settings to force it to use IRQ10.

sounds like a issue with the TNT Bios. I know that you've had other pci video cards in the system and it worked just fine. It's a long shot but you could pursue the idea that changing it to another compatible one might solve the problem That is if you don't have IRQ sharing issues. If you have a option for PNP OS yes/no and any other control in the bios I'd explore those options.

I tried this - I set IRQ15 to unavailable and it set it to IRQ9. Funnily enough, it will now reboot properly from Windows but not in DOS. In DOS it gives me a different Frequency now: 31 & 70.

I don't mind so much that it locks up in DOS since I can run Windows from DOS anyway - it's going the other way that is annoying if it locks up.

It may be - the TNT window in Windows says "BIOS: <UNAVAILABLE>" so lord knows what that means. I've tested a dozen games without issues so far so the BIOS can't be very bad ...

could be the memory range the tnt bios wants to use isn't availible to it. Somtimes theres option is motherboard bios to reserve that.

I'll have to take a look - IBM BIOS is relatively limited. I can run the majority of DOS games in Windows (some even work in Windows and don't in DOS because of the 64MB memory which Windows seems to cap).

Did you solve it? I seek a similar problem on Super Socket 7 (AMD K6-2+ 450 MHz) with Riva TNT2 Ultra. It works without driver in 640x480 - 16 colours. After installing driver, only a black screen. Switching to Geforce 2 GTS Pro, which is newer, fixes the problem.

No I gave up on it. I had too many limitations with the IBM PC330 so I switched to a different system entirely. I originally used the Riva TNT and it worked without this issue on that system but have since replaced it with the Voodoo3.
