Careful with the Reply-All since this is cross posted...
I'm attempting to get etherboot w/ pPXE to work in my environment. At
home I have 2 Fujitsu Scovery 211 terminals which have a eepro100 NIC
built in with PXE. This configuration is working fine with BPBATCH,
LTSP and a RedHat 7.0 server with dhcpd v2.
Now, obviously I'd like to ditch BPBATCH...
Here are my questions:
1) I downloaded a rom-o-matic built eb-5.02-mc1-eepro100.lzpxe
and now I wonder if there are recommended config settings?
2) I briefly scanned the mailing archives for dhcpd.conf recommendations
but have been unsuccessful. Any hints?
When my system boots, I'm currently getting:
received 000b Kbyte; sorted 000b Kbyte; invoked primary bootstrap
E6e: can't start from RAM disk image
Here's a snippet from my dhcpd.conf (am I even close)?
group {

}
}

> - PXE ROM loads the .lzpxe file and starts it.
