I have a Spot scanner card that is ISA. Whenever I put it in the computer I get a BIOS checksum error. I have an Epox EP-8KTA motherboard with the newest BIOS update. Could the computer be recognizing a setting in Windows, because my brother has the exact same motherboard, and on his it installed something called a PCI to ISA Bus. Mine does not have this driver. Any help would be apprieciated. Thank You!
