Go figure, that I, one who gives lots of Strand advice, needs some. Here is the situation, on my 520, my keyboard (external PS/2 QWERTY) has stopped working. Here is the catch though, it works in the BIOS, and in DOS, but as soon as the Strand OS loads it doesn't. I have tried other keyboards and both PS/2 ports, and I haven't found anything useful in the manual. Of course the problem persists after rebooting. My local Strand guy said he thought there was a way to lock out the keyboard, but he couldn't remember offhand how to do that. Any insight would be nice!
