Detailed netbooting network diagram for multiple OS support

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.iPXE boot process diagram

For PXE operation themselves, check the following

You also have some steps specific to SCCM

gPXE and iPXE are &almost the same (iPXE is a fork of gPXE)

For iXPE boot process, there is a figure here:

It comes from an article written in German in the German edition of Linux Magazine...

And if you want to know more about PXE/DHCP and especially the DHCP options 60, 66 and 67, read my article and its comments:

Solaris/sparc does not use DHCP or PXE.
You must get RARPD and BOOTPD running (later is somewhat covered by common DHCP servers)
