Can't boot Linux on Non-Macintosh EFI laptop

Can't boot Linux on Non-Macintosh EFI laptop

[Alexander Brüning]

Hi,

I've got a Clevo M860TU Notebook that comes with a Phoenix SecureCore NB 
BIOS which has a legacy and an EFI mode. Windows 7 (64 Bit) boots fine 
in EFI mode but I can't get GRUB2 (I tried 1.97.1 with target=efi and 
arch=amd64) to work properly. Here's what I did:

1.) Install Windows in EFI mode
2.) Install Linux in legacy mode (didn't find any working CD)
3.) Rename the "/efi/microsoft" folder on the EFI partition and 
overwrite the two .efi-files in "/efi/boot" with a GRUB image
4.) Reboot in EFI mode
5.) GRUB command line comes up (strangely with yellow text), try to boot 
"linux (hd0,5)/boot/bzImage"
6.) "error: cannot allocate protected mode pages"

Any help appreciated,

Alexander Bruening

I have a way to solve it with my relocators but they need at the moment
I haven't ported linux loader to relocator framework and it will
probably take another week to do so.
