I just built my own 1u server, I am using a desktop motherboard in the server. After I first built the server I ran Centos 3.5 on the server and everything was fine. Every time I reboot the server it was fine. Then I installed Centos 4.1 on the server and when I went to reboot the server it hangs on the reboot. The only way it will reboot on its own is with the keyboard pluged in. I have the bios set to ignore the missing on keyboard on boot up. (Centos 3.5 reboots with out a keyboard with no problem) Anyone have any idea what might be wrong?
