Somehow, in the process of trying to get my DEC HiNote Ultra 2000 to boot from either it's existing CD-ROM, or to replace it with a different drive, I have made my machine refuse to go into setup. Setup entry requires pressing of Fn+F3, during boot, and I'm starting to suspect that the Fn key isn't registering.

I've cleaned the keyboard flat-flex connectors, with both isopropyl and with contact cleaner, to no avail. The flat-flex cable is folded over, but doesn't appear to be broken. I've tried to use an external PS/2 keyboard, with an Fn key, but the behaviour is the same. This makes me think that the cable isn't at fault.

Any suggestions would be welcome!
