I have the same problem.
How'd you end up solving this?
Since you system is completely dead, I would follow the instructions on the above link very carefully and attempt a recovery BIOS using a floppy drive. I would attempt several times using the different media; floppy, CD, and USB.
If I recall correctly, I think there is a proceedure to reset the system by removing the board battery for an extended number of hours. Try to find that proceedure and follow those instructions carefully as well.
Don't forget to remove the jumper for the recovery BIOS update.
Also, if you are unsuccessful, contact Intel chat support and see what they suggest.
Good luck and best regards.
