in order to use the boot commands, you need to symlink undionly.kpxe to undionly.0 because of the appending .0 but then you can issue commands as normal, it seems after we got the dhcp-boot line correct the commands work again.
symlink undionly
[code]
cd /tftpboot
sudo ln -s undionly.kpxe undionly.0
[/code]
enable the boot lines
[code]
pxe-prompt=“Press F8 for boot menu”, 3
pxe-service=X86PC, “Boot from network”, undionly
[/code]
