Asus K8N Nforce3 M503 Silicon Image 1314 Amd Sempron64 2800 Ati Radeon 9800 pro SATA could not run under Win98SE. If only enabled in the bios ,win98se requires the pci ide driver. After that it runs under the compatibility mode. I have not found one compatible driver, that are the solution for this problem. Admiral_ZEUS
