Ok, I'm assuming a 5 slot PC with IBM roms dated 10/27/82.

"301" indicates a general keyboard failure, or keyboard not present.
"301 xx" indicates that the key with scan code xx is stuck.

Does the machine display the memory as it checks it?  If so, you have
XT roms, not PC roms.  PC's display nothing but a flashing cursor while
they check memory.

Hmm... IBM PC roms never display "ERROR. (RESUME = F1 key)",
however IBM XT roms do.

Hmm again... IBM PC and XT keyboards never had lights on them.  AT
keyboards did, and so do some clone keyboards.

It sounds like you have a keyboard that doesn't match your system.
An IBM PC has 5 slots, a keyboard port and a cassette port (for when
you run out of hard disk space :-).  An XT has 8 slots, and no cassette
ports.  Both use the same keyboard, which does not have any lights on it.
AT's use a different keyboard, which have lights, but they don't work
on XT's or PC's.  It sounds like you have an XT, not a PC, and a AT
keyboard, which doesn't work with an XT.  If it's not an IBM keyboard,
hunt around for a dip switch, lots of the clone keyboards are switchable
between PC/XT and AT mode.
