I'm working on an HP dx2000 minitower with a bad hard drive. It wouldn't recognize the hard drive I tried as a replacement and, since I could find no reason why it shouldn't, I downloaded a BIOS update from HP to see if that would do the trick. To make a long story short, I pooched the flash update but managed to correct it and the update is successfully loaded. However, every time the computer reboots, it halts during POST with the message "CMOS settings wrong. Press F1 for setup, F2 to load defaults and continue." If you press F2 the machine boots up just fine but halts again at the next reboot. If you go into setup and load and save the default settings, it continues to halt with the same message. I'm not getting why pressing F2 will allow the machine to continue and boot up normally but it can't seem to save the defaults in CMOS. The CMOS settings look fine. I've tried pulling the battery. I was going to try to rollback the flash update but there doesn't seem to be an option to do that. Anyone have a clue? Thanks. BTW, it's an AMI BIOS.
