hi. I have a huge problem about my computer. I wanted to change the logo EPA with linux inside logo but I made a mistake. now computer does not start. only wants a startup disk and runs it. The message is Bios Rom Checksum error . I tried to reupdate the bios file with the original one but it doesnt work. How can I cope with this problem? My motherboard is Abit Ka7 and it has Award bios.
