Hey All

I wrote this keyboard handler in NASM and I got it to work quite well
except for two problems:

1. When I returned to RHIDE after running, the keyboard doesn't work at
all, even though I did restore the original interrupt vector.

2. I didn't have an EOI in my interrupt so I thought adding this would
fix my problem, so I added these two lines:
   mov al, 020h
   out 020h, al
but now my system locks up completely when I press a key! Does anyone
have any ideas? What does the EOI actually do??

Thanks,
Alex
