[U][B]Regarding 1.1.2:[/B][/U]
I would suggest upgrading 1.1.2 to 1.2 and then making sure your DHCP is pointed towards undionly.kpxe for that server. With the 6400 model I noticed undionly.kkpxe doesn’t work. The default kernel should work in 1.2 if not go to fog settings>update kernel>unpublished kernels and install the 3.16*
