Hi everyone! First of all, thanks to everyone who has helped me out on here - it's been a great learning experience.

I have an IBM Aptiva 2158 Series E with a V72MA motherboard, Win98 SE. I have a Radeon 7000 PCI that I'd like to install. I used my friend's PC to determine that the card works, but when I insert the card and boot up the computer, I get no video output and despite a single POST beep (which should be a good thing) it never apparently gets into Windows or even displays an error. I believe the slot itself is fine because I tried it with a SoundBlaster and the PC recognizes that. Removing the PCI card allows for normal operation.

The BIOS settings allow for "Onboard" and "Auto" as options. I set it to Auto, but for testing purposes I've also tried Onboard with the card inserted and the VGA cable plugged into the onboard video. Still no video as long as the video card is present.

The PSU is plenty beefy. I replaced the stock PSU with a 400w model.

I've tried the VGA interrupt jumper without effect. The manual for this motherboard claims there's an "ATI Rage Interrupt Jumper" but the jumper diagram does not indicate where this would be and I can't find any unaccounted-for jumpers.

What might I be doing wrong?

Have you tried any other PCI video card beside the Radeon 7000?

My worry is that the Radeon 7000 is too new to function in your setup. I know Feipoa and others have tested alot of PCI cards in their 486's (even older that your socket 7), full thread here Modern graphics on a 486.

One of the posts in that thread describe exactly what you're experiencing, that PCI cards from the 00's just gives no VGA output, but won't stop the computer booting.

Thanks for your reply! I've also tried a GeForce 5500 FX, but that's even newer than the Radeon 7000. (Same outcome.) I've seen other people who seem to have success with the 7000 on similar hardware. The 7000 was released in 2001, so I think it's period-correct (this computer dates from 1998.)

I figured it must be some kind of setting error as I would expect setting the BIOS to Onboard graphics only while having the VGA plugged into the onboard would bypass the card anyway.

Id probably recommend trying a geforce 2mx PCI a lota people have had success with it and its very compatible use driver 6.50 you maybe able to get a MX 4series pci card working but I cant recommend that it will 100% work like the geforce 2 mx will and you wont be able to run such old drivers with it either. Older driver better performance on socket 7

Do you think it's a driver issue? I figured it must be hardware based because I can't even get into the BIOS; even if the BIOS is set to use onboard video only, it still will not do so if the card is plugged into the unit. I'm starting to wonder if, for some reason, this model of motherboard can't handle PCI videos cards or that there's something specifically wrong with this board. Or that the onboard ATI Rage chip is getting pissed in some manner. In all other respects, the board operates just fine.
