pxeboot PC Engines WRAP

[Norbert Koch]

Hello.

After having a lot of trouble with FreeBSD's pxeboot I found that a 
two-stage solution works for me. I first boot an etherboot image
via pxe and from there directly load the FreeBSD kernel.

This is my dhcpd.conf:

subnet 10.47.11.0 netmask 255.255.255.0 {
   range dynamic-bootp 10.47.11.60 10.47.11.99;
   option routers 10.47.11.1;
   if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
     filename "eb-5.4.1-undi.zpxe";
   } else {
     filename "kernel";
   }
   next-server 10.47.11.1;
   option root-path "10.47.11.1:/usr/local/diskless_root";
}

I used these options at rom-o-matic:
NIC/ROM TYPE: undi:undi
Format: PXE bootstrap loader format ROM image (.zpxe)

BAR_PROGRESS
SIZEINDICATOR
ELF_IMAGE
IMAGE_FREEBSD
FREEBSD_KERNEL_ENV
DOWNLOAD_PROTO_TFTP
CONFIG_PCI

The rom-o-matic options might differ depending on your
hardware. The undi:undi type is hardware independant
and works for me for different nics.

I hope that helps,

Norbert
