Some possible gPXE work, including modifying gPXE to not require any
BIOS support, as we used to have for etherboot.

Specifically, we isolated all the firmware-specific code so that nothing
relies on the assumption of having a PC BIOS present, and tidied up the x86
inline assembly so that it will work when compiled for a 64-bit CPU.
Building an EFI image is now just a case of running a slightly different make
make bin-x86_64-efi/rtl8139.efirom # requires gcc4.4
When I did the EFI work, I was specifically envisioning that we might extend
it to support other firmware environments such as coreboot, so the API
infrastructure is already in place. We have working reference code for
LinuxBIOS in older versions of Etherboot. Putting the two together should
not be a huge technical challenge, and would open up e.g. HTTP booting to

Marty mentioned that you might be able to secure funding for this type of
project. If this is possible, then I would definitely be interested in
working on it.
