Recently upgraded, fried motherboard, to Gigabyte brand GA-7VKMP, via KM266 chipset, 300watt ps and an AMD Athalon 2600 cpu. Original Western 10.2 HDD. Will only boot up with 98se cd in drive. Was told by selling retailer to uninstall 98SE and reinstall. Add/Remove program uninstaller says not to uninstall if HDD compressed OR if using fat32. Been there and done both. Do I really need to delete 98 (and How to) or????
