Thanks for posting, saved me lots of time

Installed the latest FOG 1.2.0 on Ubuntu 12.04.4 LTS using all the defaults advised.

When we PXE boot to inventory/Imaging a computer, we get an error:
Could not start download: Operation not supported (http://ipxe.org/3c092003)

If I pause at the point where it shows:
iPXE 1.0.0+(3a02) – Open Source Network Boot Firmware – Features: NFS FTP HTTP HTTPS iSCSI DNS TFTP VLAN AoE bzImage ELF MBOOT PXE PXEXT Menu
Configuring (net0 my MAC address)……

Then escape; I see the ‘FOG PXE menu’ as expected…

This implies a timing issue. We have experienced this on several platforms, and despite not seeing anyone on here complaining of this, wonder if there might be a bug, or a TFTP setting that needs to be changed?

My environment is on a test LAN with one ISP-router , FOG is also set as DHCP server. The same behaviour for all 4 different laptop models I tested. Also tested with gPXE USB-Boot, same result.

Any help appreciated!

Many thanks in advance.

Kind regards,
