Michael, to confirm Lead_org's suggestions... what updates were being installed? Perhaps a BIOS update was being attempted and somehow failed, leaving the system in this state?
Read this tip which references the procedure for changing the jumper to clear CMOS / BIOS - referenced above.
Download the Hardware maintenance manual for your particular system. I've looked it up for you - it's here.
See page 93 - it shows you where on your system board the jumper is - it is location 9 on the diagram on page 93. Try the instructions in the tip.
You might be able to just change the jumper location without making the diskette - try that first.
