@kevinnew22 When it uploads bzImage forever, that usually means you have a networking problem. When it errors out you are in the 2nd stage of pxe booting. The first stage is when undionly.kpxe gets transferred over to the target computer and it boots. Then iPXE will download bzImage in the second stage.
Undionly.kpxe uses the network driver built into the network cards. It is possible the network card has a bug in it where undionly.kpxe does not work. You can try to send ipxe.kpxe instead of undionly.kpxe to the target computer see if ipxe.kpxe driver will boot better.
In regards to the
kernel args of your wiki post you can find it here:
You can go in the FOG web interface FOG Configuration -> FOG Settings -> General Settings and in the KERNEL ARGS field enter
acpi=off Then save the settings. Next pxe boot the target computer again see if The acpi=off command will tell the target computer when FOS Linux is running (bzImage) to not use acpi code to talk to the hardware.
Your problem right now is with iPXE and not bzImage (where you use kernel args) so you can skip the kernel args part for now until bzImage starts up.
