Hello, first time ever basically posting on a forums looking for help with a hardware issue 🤣.
I can't seem to get any pci accelerated graphics cards to work with any of my older motherboards 🙁
Is there something that prevents slightly more modern PCI graphics cards working with older pre AGP time period motherboards?
I have a PCI FX5200 and a brandnew HD2600 Pro (I litterally brought it sealed in box for the most chance of it working)
I am trying to install either of them in 3 computers,
A SL-54A5-S baby AT motherboard with a AMD K5 PR166 processor,
an MI5VP4-1.20 with a AMD K6-2 500
and finally a P5S-VM with another AMD K6-2 500.
Non of these boards will boot either card, but they will boot a PCI ViRGE card.
I've been scouring everywhere I can think and google, but its very hard to type "PCI" into google and
actually get information about PCI graphics cards as oppose to PCIe.
Does anyone know what prevents these cards working? Is it some strange voltage requirement with newer PCI graphics cards, an addressing issue or PCI standards or something?
The HD2600 Pro lists itself as being compatible with K6 processors also.
I have checked both cards in much more modern computers and they are working perfectly fine.
I've basically given up on my dream of having a massively pointlessly bottlenecked retro build for the lolz, but I'd really like to know why they don't work.
I've been working on this for almost 2 weeks and its really bugging me not knowing 🙁
