What OS version are you running
RHEL4 at the moment - although that's just for testing.
initrd's have been cpio for a while now.
The pxeboot initrds appear to be filesystems...
Anyway - adding the forcedeth driver didn't help - it was already there.
It just doesn't want to work with RHEL4; although the module gets loaded,
the network interface is not seen. That kinda puts a crimp on a cobbler
installation :-(
Time to do some digging...
