Hi list,

ist it possible to keep some variable values over warm reboot? The idea
is to execute something from net, the reboot and second time ipxe-script
knows, that he was just rebooted before, so he is able to do different
actions like local boot.

Imho there exist a battery-buffered cmos-ram for saving values most for
bios. but maybe this is useable for ipxe, too?

Alternativly, could it be possible to start a boot from 2nd source of
boot order directly out of linux?
