Have the old PC I run a small cnc mill with. Put a real time version of Ubuntu on it to run steppers from the parallel port. Haven't used it in some time and now it go to a configuring IDE message. CMOS battery was dead so replaced it. Still same. I hit F2 during boot and it shows "entering setup" briefly before going to IDE config message. Saw somewhere to try a live CD - no difference there either. Any ideas? I could try disconnecting the IDE drives and see if that lets me into setup. Then once configured reattach the IDE drives.
