| | 
| 

| | | | This was working for me, but broke as of
| | | 
| | 
| 
| | | | fc87adb commit... If I back that one out, chain loading efi
| | | | images
| | | | from snponly.efi works again...

| | | | | | | 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?
