paranoid chainloading script for flimsy tftp

[lstraath]

Are you chainloading undionly.kpxe and want a universal script to break the loop...

Code:

#!ipxe
:label_retry_dhcp
dhcp && goto label_check_loop
set countdhcp ${countdhcp}x
iseq ${countdhcp} xxx || goto label_retry_dhcp
reboot
:label_check_loop
iseq ${filename} undionly.kpxe || goto label_no_loop
set filename ${filename}.ipxe
:label_retry_chain
chain ${filename} ||
set countchain ${countchain}x
iseq ${countchain} xxx || goto label_retry_chain
reboot
:label_no_loop
autoboot ||
set countautoboot ${countautoboot}x
iseq ${countautoboot} xxx || goto label_no_loop
reboot
