Enter server EFI Boot Manager and select USB media 5. Obtain grub shell 2.00~beta insmod part_gpt insmod part_msdos insmod ext2 insmod fat set root (hd0,2) linux /vmlinuz root=/dev/sda1 ro error: cannot allocate real mode pages (2.6.32 kernel from CentOS 6.2, same error with Fedora 16 kernel; same error using grub.efi from Fedora 17 Alpha grub2-efi) 8. This same UEFI firmware boots kernels using grub-legacy-UEFI from Centos6.2 install DVD. Chainloading grub->grub-legacy->linux works 9.
