HP laptop hanging at iPXE initialising devices...

ndogmail - if you're not in the position to try bisect'ing the git commits i might be able to try it if we get another G42 through the repair workshop - do you know the specific machine p/n of it, i'll check what other models used the same mainboard.

that said and slightly de-railing your original request - can you clarify on how you're ipxe booting the macbooks & macbook pros? are you dhcp/bdsp(netboot)'ing them or using a compiled iso on cd/dvd and using that to bootstrap them onto the pxe network? it's a problem i've been looking at periodically aswell and even attempting to do an efi version i still couldn't work around all the issues short of falling back on throwing a cd in to boot. :/
