[CentOS] Two ethernet adapters and more

I am running Asterisk at home on one of my systems here.  It uses Centos 
4.2.  It does NOT have a GUI interface.  Command line only at console 
or via SSH (yeah, I know that I was working on another server to get 
GUI tools working through SSH, but I am NOT going to muck with AAH build).

yum update is potentially dangerous, when it replaces the 
kernel.  You can loose all of your Zaptel driver setups and have to 
rebuild them.  This is a given, the first time you install AAH and 
run yum update....

Now at 
http://www.voip-info.org/wiki/view/Asterisk%40Home+Handbook+Wiki+Chapter+3

I was instructed to use NETCONFIG to setup up my network 
information.  Well it did for eth0, but not for eth1.

So question #1 is how to use netconfig to setup eth1 without messing with eth0.

#2)     NETCONFIG did not setup my hostname and domain.  I had to go 
in with VI to resolv.conf and sysconfig/network.  Is there a tool for this?

#3)     How do I figure out which board is which.  Other than looking 
at the MAC address and using PCISNIFFER to then relate that to one of 
the boards (well, one 'builtin').  Also how do I determine which 
board is using which IRQ.

#4)     Finally how can I change which IRQ a board is using.  As one 
of the boards is using the same IRQ as one of my Zaptel clone cards 
(Tigerjet chips according to PCISNIFFER).

#4 leads into the 'more'.

This system has TWO FXO clone cards.  One is working in AAH, the 
other AMP does not see.  Asterisk CLI flags one as "alarm"  RED.  and 
does not report the IRQ of either board.

#5)     How do I figure Centos has configured these two cards, and 
what IRQs are used and maybe how to change the IRQs.

#6)     Then how to get genzaptelconf to properly configure this card.

         If you're smart enough to use one of these....
                 .....you can probably manage without one!
