Make sure you've got AGP fast writes disabled?

I have just built a computer with an Athlon XP 1600+ processor and an Abit KT7A motherboard under Windows 98SE. However, there is a problem - games using DirectX9 freeze immediately after entering the 3D environment. All other games using lower versions of DirectX work without problems. I checked it on ATI 9250, 9550, 9600, Nvidia FX5500 graphics cards and it always freezes. I changed RAM and all possible options in BIOS but nothing helped. I changed the processor to Atlon XP 2500+ but the problem still occurs. The same games run without any problems on my other computers with Pentium 3, 4, Core 2 Duo, Phenom and Windows 98.

I'm starting to wonder what's causing this problem, is it a motherboard or maybe Athlon XP is incompatible with DirectX 9 under Windows 98?

The KT7-A is known to have flakey AGP... Keep trying other cards until you find one that is stable.

Can you run the Direct3D test cube under dxdiag? Tried disabling AGP texturing support in dxdiag? What happens when you run 3Dmark 03 (version 3.4.0 supports Win98), does it crash at the nature benchmark that uses DX9? Tried reinstalling DX9? I have a KT7A and it never freezes with any graphics card, but it absolutely hates Athlon XP's. I was getting black screens at boot, frequent crashes and freezes. I have just accepted it and switched to an Athlon Thunderbird, it's a much better fit anyway.

Back in 2001 when I had a Kt7A I used to use Paul's Unofficial KT7 FAQ quite a bit for solving issues. Though it's long gone, it's still on the Wayback Machine: https://web.archive.org/web/20020205141221/ht … /kt7/kt7faq.htm

maybe via 4in1 drivers? i run ati 9800/9600xt cards on kt133a boards (palomino athlons) with no issues in win98se or xp.

I had enough of this board and sold it today.
