| I just go around to revisiting this after the recent snponly UEFI | work and using | chain | http://mirror.its.sfu.ca/mirror/CentOS/6/os/x86_64/EFI/BOOT/BOOTX64.efi | || goto failed | just seems to drop me to a grub prompt and nothing else. Am I missing | something. | ----- Original Message ----- | | Yes: | | | On Wed, Apr 10, 2013 at 1:27 PM, James A.

Such a thing simply | | | | | | | does | | | | | | | not | | | | | | | and | | | | | | | can not exist. | | | | | | | | | | | | | | | | | | | | | | | | | | | | Michael | | | | | | | | | | | | | | | | | | | | | | | | | | | 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? | | | | | | | | | | | | | | | | | | | | | Joshua | | | | | | | | | | | | | | | | | | | | 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.
