Thank you DEAT.

Hello
I have 2 Diamond Stealth video 2500 promotion at24 pci card with bios v1.03.
I tried with modded 2052 and 2072 drivers, with Windows98SE
Both card after installind driver and reboot after windows 98 splashscreen give an interesting pixelated picture.
What was wrong?
With which driver can i use this card?
Or windows98 is the problem?

Thank you

It looks like the drivers clocked the memory way too high. You can adjust it with third-party tools like Powerstrip.
But AT24 does not belong in this thread about 3D cards.

Re: Worst fastest early 3D cards questions

Drivers may work with an AT25 and aT3D card but the AT24 wasn't really the same and even if working they were different projects; even the AT25 might simply be a rebrand of the aT3D or probably a lighter aT3D revisited project to be sold as cheaper 2D only accelerator or somewhere in the middle.

Yes, sorry i was confused.
I think alliance at24/25/at3d is the same chip.
I read elsewhere about Diamond stealth video 2500 is a dx5 card, but with original driver no direct3d
