IBM x-series 335 keyboard problem

[isutcliffe at rocketseed.us (Iain Sutcliffe)]

Hi,
 
I am trying to install v5.2.1 onto an IBM x-series 335 server. It has a
single cable with which to attach the monitor/keyboard/mouse that enables
daisy chaining of servers.
 
When I install I get to a point where I have to enter information and the
keyboard doesn't work. I've tried several times with no luck.
 
Do you have any known problems with these systems?
 
Regards
