Your graphics card doesn't support the Win9X. You have to install either Windows 2000 or XP.

I guess your re wrong. It is supported. See my posted links e.g.

Radeons usually have two instances in device manager. Is there another GPU in the dropdown menu of HWInfo?

Nope, only one (GPU 0)

@rotzgurke

do you see any 'unknown devices' in device manager?

Sure. 1 unknown device for the motherboard. There are No drivers at all. But should that complain with the GPU?

I only Run quake 2 today. Seems right.

Anything i can Test to get Sure the GPU is running correct? I installed 6.2 again. The only Driver thats fully working.

ATI cards from this era normally have a 2nd 'Secondary' device under display adapters, it should be there so that might be part of the problem.

Try installing the ATI Catalyst 6.2 driver onto the unknown device and see if it lets you do it.

Also try recapping your card if you've got the skills for it.

Ah that you mean. There are two Display Adapters.

1. Primary Radeon 850 xt
2. Secondary Radeon 850 xt

ah OK. so that's good.

Can you try and put the card in a modern system and run MemtestCL on it to check if all the VRAM is working?

How about quake3 time demo or 3dmark2001

Quake 3:
Hit the ~ key
Type: timedemo 1, Hit Enter: Hit ~ again and go to demos and select one.

3dmark2001 is free. run it and see what you score or if it fails.

You could also try pressing the windows key +R and type dxdiag navigate to the display tap and see what it says.

Thanks for your replies. I will Check this end of the week.

I wonder if it's MTRRs being messed up... source : Re: "Linux Daily Driver / Win98 overkill" LGA1366 build

I recently tested an ATI X700LE with Windows 98 or very modern hardware, and it works just fine, except that the X700 is quite bad compared to an X850.

Check if the video memory shows up in DXDIAG. Utilities like HWiNFO are not optimized for Windows 9x and you can't expect everything to work... it's a miracle they even start.

What is the dvi2usb Display Adapter?

That and I would like to know how a PCI-E graphics card has AGP texture acceleration enabled?

DVI2USB is a capture card (from Epiphan) that will present itself as a Plug & play monitor in Windows.

As for AGP texturing, I'm using a PCI-E x700 card, so this option isn't on the table.

I guess it is okay then?

Now i tested Mafia 1 and it ran smooth. So i guess everything works. Now next how to Higher reolition without blackscreens more than now as shown in the picture above.

Info: it is connected via DVI to HDMI cable

You are lucky.
My PCIe ATI X300 does not want to work in Win98 or Win95 on any computer on which I tested: Haswell, SandyBridge, BayTrail, CoffeeLake 🙁

Some X850 cards are missing the subvendor and subsystem IDs in their ROM and they won't work on Win9x:

Re: Radeon X850XT and Windows 98SE problems

I ran into that problem with my X850XT. Worked totally fine on XP, but the PC made a hard shutdown when trying to boot Windows 98. Now it runs flawlessly after modding and reflashing the ROM.

Thanks for your link

Any ideas why i am Not able to Change Resolution to full hd? When i do that this time No blackscreen but a Strange flickering Screen/picture. It is bouncing left and right.

Now my Resolution is 1600x1200 32 bit

As for the PCIe ATI X300 card, it has the correct subsystem and subvendor but still does not want to work in Win9x:
