| | This will give you an iPXE EFI ROM; you'll see it show up as "EFI
| | Network" in the EFI boot device selection screen, and it should
| | thereafter look and feel similar to normal iPXE.
| 

| | There is no such thing as a non-EFI (aka BIOS or "legacy") ROM
| | which
| | is capable of loading an EFI image. Such a thing simply does not
| | and
| | can not exist.

| I didn't know this. Up to know I've been using a modified version of
| ipxe that gives me a shell after initilizing the devices (just a
| modified main() function), so that I can load and boot any image
| over a network. I've always had all image types enabled in general.h
| and never had an issues when starting ipxe. Right now my system just
| reboots regardless of the not supported IMAGE_EFI. From my point of
| view this is a regression, because befor this commit ipxe started
| without glitches regardless if an image is supported or not. So even
| if the image is not supported then ipxe should gracefully continue
| initilization and not reboot the mashine....

| From the shell I can point to and download any efi image over the
| network, but why it cannot boot the system?

I have iPXE working with both legacy BIOS and EFI machines right now, except that I can't get it to chainload to an EFI bootloader such as CentOS's BOOTX64.efi. I always end up with "Could not boot: No such device", although considering this is my first time trying to do this I'm probably not doing it right. I'm just trying with 

chain http://mirror.its.sfu.ca/mirror/CentOS/6/os/x86_64/EFI/BOOT/BOOTX64.efi 

which is probably not right. Any ideas?
