welcome to forum. The drivers require .net 1.1 and dx9. Did you install those 2 packages? Did you install the intel chipset drivers?

Thank you !
Yes, .net 1.1 and dx9c are both installed.
I'm not aware of Intel chipset drivers for windows 98 for this motherboard (LGA 775)

Go to add and remove programs, unistall the ATI drivers. Reboot, press f8 to go into safe mode. in safe mode go into device manager. Remove the display adapters, remove the monitors.

Restart and try the unofficial omega drivers. Maybe the GTO varient will work with them http://vogonsdrivers.com/getfile.php?fileid=1672&menustate=0

Reinstalled win98, patched RAM, installed DX9 and .net framework. Unfortunatelly omega drivers won't install with my GTO2.

If you can get the cards hardware ID from a program like SIV, then modify the driver INF and add all of the necessary strings for your card you might have a chance.

Technically on paper the card should work like a x800gt, but it probably has a different hardware ID than a x800gt and so thats why its not working for you.

Or your motherboard is causing some kinda incompatibility, but seeing how other people have had success with unsupported motherboards and installing graphics cards I can't say for certain.

Unless you have experience with driver modding, and trouble shooting all of the problems with running unsupported hardware on 9x, and hacking it. Id recommend against it.

Even people who know how to do that and are good with it still have trouble all of the time, and in the end even if they get it to work its buggy and unstable.

Hey Warlord, thanks for the comprehensive analysis!
I'll try to get this thing working a couple days more. If it doesn't I'm sure it'll be a terrific windows XP system!

I'm currently setting up a asus p5kpl-am se. Install the catalyst drivers only first then after tweaking the resolution and a restart you can install the control panel. That's how I managed it with a x850.

I have a question for you. Did you get working lan drivers? I've tried 7 or so and no luck. I'd really like to have it working for file transfer.

I actually gave up on installing windows 98 on this machine, but you are giving me hope. I'll definitely give it a new try. I'll let you know about the LAN drivers

I've got mine running great just no lan unfortunately. I'm also using a sata optical drive with no problems. I'm not sure why but I only had sucess with catalyst drivers first, then soundblaster, then I ran the 98se autopatcher and usb upgrades after. The unofficial service pack gave me some problems . But getting the essential drivers set before anything else was the only way that it didn't give me problems. It took me a day to figure out the video card. It was definitely doing the drivers first that made it work. Same with the soundblaster.
