starting script from command line

Yes, or they embed them in the ipxe binary (undionly.kpxe/ipxe.pxe or ipxe.lkrn).

For the first time users, it would be safe to say that the CTRL-B command line is where you get your feet wet, but past that, it's all scripts on a webserver or a PHP engine.

That's the beauty of iPXE; you can compile a small embedded script which executes a certain repeatable process as specific or as general as you want; once that process is established, you can expand or leverage it further as you see fit.

Myself, I have an embedded script which attempt to dhcp (three times) and checks for the UUID of a system as the chainload file. If it's not there, then it exits out. If it is there, it executes whatever is in the script.

Example embedded script:

#Generic Boot Script

set 0_attempt 1


dhcp ||
isset ${17} && goto 0_next ||
iseq ${0_attempt} 3 && goto 0_end
iseq ${0_attempt} 2 && set 0_attempt 3
iseq ${0_attempt} 1 && set 0_attempt 2

goto 0_retry


chain ${17}/ipxe/boot/${uuid}.ipxe ||
