PXE Menu Help for Linux Newbie Please
I've no experience of Linux at all and have been left with a problem that I have to solve on my own (no help for several weeks and I'm the only one here).
Our Fog server was setup by someone else who no longer works here and it appears to have lost one of the custom menu items he put in place.
Our Fog server used to have a custom PXE menu that gave the option to load a different kernel (PS Kernel-188.8.131.52.PS) so we could register and image certain Dell PCs. That menu item has just disappeared and I need to put it back in. The kernel is still in the tftpboot/fog/kernel folder (along with the BzImage one).
So far I've managed to VNC into the machine and get to the /tftpboot/pxelinux.cfg/default file and the have found out that item is not listed anymore. I need to get it listed again and have it loading the correct kernel when selected. As mentioned I'm new to Linux and can't even get this file to be not read only.
Any help at all would be welcome.
