Exciting to see someone having success with Win98 on PCI-E systems. Have a HP Compaq nx8220 laptop that i am experimenting with and have installed the Intel chipset drivers (915/ich6 on this), audio, etc, but came to a halt. I struggle to get drivers for the onboard ATI Mobility Radeon x600 thats PCI-E. Same problem with the Broadcom NetExtreme gigabit ethernet, but thats not important. I think modifying the inf files could do the trick, but dont know where to start.
Reading someone says that would never be sucsessfull to get a PCI-E device to work properly in Windows 98, but with chipset drivers in place shouldnt it work? Just out of couriosity i tried to update all drivers under the System Devices that didnt have Intel ich6 driver to also use the ich6 driver instead of MS genetic driver. No problem with that, but if that have any parctical effect i dont know.
I believe the x#### video cards from AMD are too new to work in windows 98 is the problem, there were never any official amd drivers for that family of cards. The last AMD GPU's officially supported in Win98 are the ATI 6000 series, like the 6800 Pro, etc. Also on nvidia side the only officially supported gpu's are the nvidia 6000 series, like the 6800 ultra. So the system probably works fine, your gpu is just too new.
You mean Radeon 9000 series?
I think at some point the Radeon x300-600 series might be able to work in Windows 9x due to begin very close with the Radeon 9600
Radeon x300-x600 were just rebrands of the Radeon 9600 cards in PCI-E, RV370/380 are just PCI-E versions of RV350/360
So, on desktop:
x300/x300LE = Radeon 9600
x300 SE = Radeon 9600 SE
x550 = Radeon 9600 Pro w/ mem underclock (at least on the 128 bit model)
x600 Pro = Radeon 9600 Pro
x600 XT = Radeon 9600 XT
Mobility x300 = none, closet is Mobility Radeon 9600, with Mobility Radeon 9600 Pro clocks and 64 bit bus
Mobility x600 = none, most likely an underclocked Mobility Radeon 9700
