I put a line in my dhcpd.conf file something like the following;
host rhel5ppc2.olysteel.com {fixed-address 192.168.0.53; hardware
ethernet ca:10:e0:00:40:03; next-server 192.168.1.137; filename
"ppc64.img"; update-static-leases on;}
You have to know the mac of the PXE client nic. Maybe you shouldn't
have a pool in your config file either or a different pool of maybe 1
address for the nic you want to PXE boot.
