My understanding is that they prefer a bootloader which can launch Linux as a PE/COFF image, i.e. the linuxefi thing. > Instead the majority of users would like to use a bootloader, like > GRUB2.

"linuxefi" won't call ExitBootServices but it will launch as a PE/COFF application not as a "Linux image", that's right isn't it? I think that is the whole point of it. The "launch as a Linux image" grub command is called just "linux" (and "kernel" may be a synonym). > But I say that (about ExitBootServices) - and I can't find it in > the GRUB2 code, so perhaps I am mistaken. linuxefi isn't in the upstream grub2 tree -- all the distros are carrying it as a patch. So if you are grepping upstream you won't find it. Ian. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
