No keyboard function uo boot up
Posted on 2004-09-30
This is a strange one,
A friend gives me his computer to fix because it won't boot up. It just says no operating system present. It is a custom built machine, about a year old, that I did not build. The specs are ABIT IT7 with P4 2.53, 1GB Mushkin memory and 2 WD 80GB HD in a RAID 0 array. It seems the RAID controller would not pick up one of the drives. Check the obvious cables PS connections etc. everything looks good. Ran diagnostics on the failed drive in a test bed computer and it did not pass.
This is where it gets weird.
Replaced the drive with an identical one and proceeded to build the array. I could not get into the RAID Controller BIOS. The keyboard seems to not function. I tried to get into the MB BIOS and the keyboard still does not function. This is an interesting MB because it does not have any connections for leagacy devices. No PS2, no serial ports, no parallel ports, just a bunch of USB and Firewire. I tried different keyboards and tried using a USB to PS2 converter with a standard keyboard and nothing.
The next thing I tried was putting a HD on the standard IDE primary channel as master. I couldn't get it to boot off the CDROM. It always wants to boot off the HD and nothing else. I can't get into the BIOS to check the Boot sequence.
My last resort was placing the HD in another computer and installing the OS there then putting the drive back into the machine and it finally boots up. The mouse, keyboard and everything else works in the WinXP environment but will not work when the machine boots up. Only when it boots into Windows.
Any suggestions, been working on this for days and I still need to get into the BIOS
