It gets worse… Now, even the “reboot from a working CF card” trick isn’t working for me. I can’t get it to display the boot menu in the BIOS at all. When booting, the keyboard is simply ignored, no matter what the history is.
So, I can’t find out what the firmware rev is… It requires a working keyboard to find out! I’m at my wits end!
