iPXE is a PXE boot firmware which can be used to PXE boot systems that may not have support. iPXE supersedes the older and no longer actively maintained gPXE boot firmware.
Building
You can build the iPXE image from source pretty easily with the added benefit of being able to customize the image with custom iPXE scripts.
Example
The following script will build iPXE with an embedded script which automatically boots from a HTTP resource.
# git clone git://git.ipxe.org/ipxe.git
# cd git
# cat <<EOF > arch.ipxe
#!ipxe
dhcp
set 209:string cfg/arch.cfg
set 210:string http://linbuild.cs.ucalgary.ca/archlinux/boot/
chain ${210:string}pxelinux.0
EOF
# make bin/ipxe.lkrn EMBED=arch.ipxe
Troubleshooting
If you get the following error while building:
[VERSION] bin/version.udionly.kpxe.o
[LD] bin/udionly.kpxe.tmp
--defsym:2: undefined symbol `obj_udionly' referenced in expression
make: *** [bin/udionly.kpxe.tmp] Error 1
rm bin/version.udionly.kpxe.o
Install the syslinux-devel package.
