OT: Ethernet Install guide for AS400

I am sorry for this as it is completely OT, however I find that trying
to get ahold of people that are familiar with AS400s in my parts is
quite difficult.  Would anyone here know where I could find instructions
on how to properlly install ethernet cards into the following models:

9402 400
9401 150
9401 170

The company that uses these systems until last week had ban'd the use of
ethernet cards in the system.  I assume that once the card is installed,
I can use the Linux 5250 to get full system access?  Are there any other
free windows programs that don't suck for this as well?

Again - I am soo soo sorry because I know this is terribly off topic (I
have been a list member for a few months now but am always so bogged
down I never get a chance to really read up on this stuff).

Any help would be greatly apriciated!
