Build GRUB for UEFI (not EFI), 64 bit

Build GRUB for UEFI (not EFI), 64 bit

[gburanov]

Hello everybody.

I am currently trying to build grub for UEFI (I got new modern Intel motherboard that support boot loading).

According to the grub manual, I use

./configure --with-platform=efi --target=x86_64
make
./grub-mkimage -d- -o bootx64.efi modules_list

and try to load from it. it does not work! The computer just restarts when running it, in the beginning. 

However, the grub that is included to the Fedora 12 CD works just fine.

Do somebody succeed in compiling grub for UEFI (not just EFI)? What can be a problem?

It's "-d .", not -d-, also be sure not to include kernel in modules list

I am curios which one. I have a DP55WG and I did not get UEFI + Linux
working. UEFI + Windows 7 on the other hand works fine. The EFI Shell
also works fine.

you probably need newreloc branch.

yes, if you are talking about 32-bit emulation of UEFI, created by
Tianocore, then yes =)

I tested with 64-bit qemu-tianocore actually, and in this case it's not
an emulation.

Hm hm that sounds very interesing. Can you please send me your compiled EFI
file? I will test it on my UEFI. If it work than it's the problem of my
compilation, if not then it's the problem of my UEFI implementation

Vladimir can you please send me your compiled grub2 for efi, 64 bit? I will try to run it on my computer?

Okay, tried that out too. Did not work well either.

When I give kernel arguments grub says:

Anomaly in region alocations detected. Simultaneous relocators?
Boot aborted. Press any key to exit.

Screenshot: plai.de/grub1.jpg

If I do not supply kernel arguments, it may boot or not:

>boot
error: no suitable mode found
Booting however
error: no video mode activated

But without video and the kernel not mouting the filesystem (so no
remote) it is hard to tell.

What you were doing exactly? This message is a part of unloading
relocators which shouldn't even be called unless you try to execute
"linux" for the second time

You need to
insmod efi_gop
or (for older systems)
insmod efi_uga

You seem to be right. I could not reproduce that error without loading 
the kernel twice.

With either efi_gop or efi_uga loaded the system simply goes black as 
soon as I use "boot". Any idea or pointers to debugging?

isnmod efi_gop followed by videotest

That somewhat works. I get a black screen with a red square and
white/light blue (could be my monitor) square. And then the computer hangs.

With efi_uga. videotest just says that no videomode is available or
something similar.
