I guess that should be 'fakebios'. > error: no suitable mode found After 'insmod efi_gop', could you try 'insmod gfxterm' and then 'terminal_output gfxterm', and see what happens? Before the terminal_output command, you can also use 'set gfxmode=MODE' (e.g. 'set gfxmode=1024x768') to change its mode selection. gfxterm can help matters here, as that way you have a working video mode that the kernel can be told to inherit, rather than having to probe its own. Unfortunately right now it's hard to get debugging information on EFI video modes. Since you're building your own GRUB anyway, though, you could try this patch against trunk: http://people.canonical.com/~cjwatson/tmp/grub-efivideoinfo.patch That will give you an 'efi_video_info' command, which should dump out the available GOP modes, and might be useful to get a slightly better idea of what's going on. > booting however > _ > > And then nothing else happens. It's possible that the kernel may have booted successfully, but that you simply don't have a working console. It would be useful to try pinging the machine to test that. > I've also tried newreloc, but I don't think this has anything to do with > relocations.
