Has to be a regular pci slot, not pci-e. But yes, you should be able to, easiest via booting to freedos or the like.I just purchased a Sapphire Radeon 7000 64MB PCI card on ebay for pretty cheap. Going to order the ROM chip on mouser and hope for the best. I'm assuming I can just throw the card in my current PC's PCIe slot and flash it from there?
