you said "I've tried three different keyboards (one PS/2) and all with the same result."
Yeah, well it actually seems like there was nothing wrong with my old PS/2 as my friends one had the same problem.
Anyway, I've sort of solved it for the time beeing, I decrypted the HD using my old computer and I can now get into the OS on my new one. But the old problem still persists. I still can't do anything in BIOS, the keyboard, no matter what type I use just refuses to work during boot.
It's not a problem right now but it will probably be quite a hassle sometime in the fututre, which is why i'd like to try and solve it sooner rather than later.
Is there anything I can do?
