I'd like to play around with booting an HVM directly off an iSCSI share.  One of the ways to do this is with an iSCSI Boot ROM.  The latest versions of gpxe allow for this functionality, and I was wondering if there's a somewhat-simple way to replace the etherboot .zrom file with a gpxe .rom file.  

I've already tried the obvious - use rom-o-matic to generate the gpxe file for the rtl8139 network card, then use the tools/firmware/hvmloader/mkhex utility to make it into a header file, and then replace the line in the tools/firmware/hvmloader/Makefile that cats the eb-rtl8139.zrom.h file into the roms.h to cat the gpxe-rtl8139.rom.h file into the roms.h header.  If I do this, then try to use the newly-generated hvmloader to boot an HVM, it doesn't want to network boot at all, even if the only boot= argument is "n".

Anyone have any hints, or is this just not possible right now?

Thanks - Nick
