Hi - I have Linux installed on a hardrive on a pentium box which
originated on a CD (APC's RedHat Distribution).  I also have a 486
with no CD which I would like to make a Linux box as well.  In other
words, I would like to access the pentium box's CDrom from the 486. 

Currently the 486 has muLinux installed on it, downloaded from the net
and installed using 3 floppies. 

All I have to connect the two is a null modem cable.  According to the
RedHat docs I should be able to install from the CD via a network but
do I need a network card for that?  Is the /dev/cua1 port sufficient?

I have read all the docs from the LDP and the RedHat distribution but
my head is spinning around!  Could someone please please explain in
English for me how I connect the two (i.e. what protocol, what scripts
etc).  I'm sure someone has had to do this before.

I thank you in anticipation,

Cheers :)
