When I updated my amd raid rom the bios didn't boot and stops at the logo screen. By pressing the esc-key during power on it shows me the diagnostic screen and the amd raid rom copyright. It starts scanning the sata drives and then boot is okay. Hence this work but I need to press esc key to boot? So I went into the bios and unlocked the diagnostic option and enabled it in the bios?? This doesn't work either and I still need to press esc key to start the scanning for sata drives. So I decided to start again but now I can't enter the bios again?? F2 don't work and I'm stuck with the diagnostic screen? I want to change my boot order but I can't. How can I reset my cmos? My bios is a Phoenix bios?
