Radeon Xpress 200 and Radeon X800 refuse to work on 98SE

[JukeBoxHero]

I have a ASUS A8AE-LE mobo supposedly from some HP/Compaq machine, which has an RS482/SB450 chipset. The mobo contains a Xpress 200 graphics chip which I am temporarily on due to the failure of my Radeon X800. Works great in Vista and XP but on 98SE I am having issues. The Catalyst 6.2 drivers claim to support it but refuse to work no matter what. XP identifies it as "Radeon Xpress 200 Series" and when installing it as that in 98SE I see the Windows 98 logo on boot and then it immediately stops outputting video signals. I should try and install Catalyst 6.2 on XP to see if its the issue, but I'm not exactly sure what's going on.

Try to limit the amount of shared memory to minimum. IIRC X200M max share is 256MB so it should be fine in Windows 98.

I didn't think memory would be an issue (I have 2 sticks of 512MB DDR-400 which show up in 98 at around 900MBs so maybe). Can I limit it's memory in the BIOS?

It's also useful to add that Catalyst 6.2 claims it finds no supported device which prevents installation, but Catalyst 10 on XP installs and works fine.

[Omores]

Yes, you can limit the memory. It looks like now you are using 128MB, which should be totally fine with Windows 98.

But if the Catalyst doesn't find the card - and no drivers are installed - what causes the black screen? Did you installed them manually?

Can you post a screen capture with all devices present in Device Manager?

Yeah, I installed the INF files directly, Windows extracted all the neccesary DLLs to the system folder as well.

Whats the Device ID of your Xpress 200 graphics chip?

Any way to check this on 98SE or will the device ID it gives me in XP be fine?

@bob_smith

It is admittedly not as easy to get a DeviceID in 98SE as it is in XP.

It's easiest just get the DeviceID when booted into XP, it won't have changed between the 2 OS's.

You can use "hwinfo /ui" on 98SE FWIW.

Device Instance ID :

PCI\VEN_1002&DEV_5954&SUBSYS_2A26103C&REV_00\4&1C9EB71F&0&2808

Funnily enough, got the X800 GTO PCI-E card and 98SE is still doing the exact same thing now, is this some sort of a chipset issue?

[JukeBoxHero]

Think I found something contributing to this issue

[Damnation]

@bob_smith

Yeah, that would have something to do with the issue.

Not sure about this one though, try disabling IRQ steering?

[jumper]

Under IRQ Steering, first deselect Get IRQ table using ACPI BIOS. What does the IRQ Routing Status say?

 

[pangoomis]

Catalyst 6.2 for 98SE/ME does have support for PCI\VEN_1002&DEV_5954

Try reinstalling 98SE with "setup /p i" switch to disable ACPI.
