Re: [PATCH] x86_64 EFI support for grub2

[Bean]

Hi,

Ok, I solve this now, the new patch is capable of booting Linux from
x86_64 EFI. In theory, it should also be able to boot from 32-bit EFI,
but I haven't verified it yet.

You should add root=/dev/sdaX command line so that it can find the
root partition. After booting, it may seem hang, just give it some
time, it could still be running. After a short while, you should see a
scramble screen, that's it, linux have started !

The reason of scramble screen is that it can't find the proper frame
buffer driver, you can add the following line to .config

CONFIG_FB_IMAC="y"

and recompile the kernel. You should also add parameter like
"video=fbimac:macbook" to the command line. For more information,
check out Documentation/fb/imac.txt in the kernel source.

BTW, you need 2.6.25 if you are using x86_64 firmware. 2.5.24 is not
working ! It actually cause me a lot of time to figure this out.
