Actually, there is a keyboard that is USB. The only thing plugged in, apart
from the power cord and LAN cable.

Now that I think of it, I may have not plugged the keyboard in when I took
the computer upstairs for troubleshooting, and maybe that is why it worked?

But I think I did plug it in before I got it to boot and run for a few
minutes.

Hmmm.

I use ssh, but that works when things work. Not when I am installing or
troubleshooting something low level (like this case).

There are 4 servers in this location, and one monitor. Moving the VGA cable
is a pain with the snake den that is there. Hence me contemplating a KVM.

Re: memtest, that needs the stage where it reads media to boot from, and it
does not reach that stage most of the time.
