I’m looking for detailed info on differences between iPXE, gPXE, and PXE for the networking booting and loading of OS for RedHat RHEL4 through 6 via DHCP & kickstart, Microsoft Windows 7 and Server 2003 to 2012 via SCCM, and Solaris 2.6 to 10 via Jumpstart.
I understand that all of them use a “flavor” of some process (e.g. client powers up, does a POST, does an INT13 and sends out a broadcast via ethernet to a DHCP server where a handshake ensures, if gets the OS from a TFTP, etc)
I have been searching for a few days now of the differences in how these work, and I have yet to find a good diagram for how these work. We are finding that there are minor differences between gPXE, iPXE, and PXE itself.
I was hoping to find info like this attached example for a ESX host boot but showing which ports and protocols that are needed.
