Re: [RFT] PXE chainloader

[Omni Flux]

The output of two tests follow. It works, to an extent. Is PXE being 
left in a state where the next bootloader can call it's initialization 
routines again?


Test 1: Boot grub PXE, chainload grub PXE, chainload grub PXE again.
Result: Chainloaded grub PXEs load in rescue mode.
