I replaced the motherboard of my computer, which was dying. So now I have a new one with UEFI firmware, which prompted me to try to use it. Problem is, right now, I am only able to run in legacy mode. But what I have done, which may be relevant to this thread and testing instructions is to use a qemu VM with EFI firmware (just added -bios OVMF.fd to the command line options, I use Debian's qemu and oackage ovmf is installed). Then, I got to the point to be able to load grubXXX.efi, and to have it boot the kernel. So this is a good solution to testing instructions... Roughly, building grub-efi just amounts to add --with-target=efi to the book instructions, assuming: a) freetype2 is on the system (no need for fontconfig), then grub has been (re)built once to install grub-mkfont, and is now rebuilt with grub-mkfont installed. b) there is unifont.pcf in one of the subdirectories of /usr/share/fonts (can be downloaded from http://unifoundry.com/pub/unifont-7.0.03/font-builds/unifont-7.0.03.pcf.gz). unifont.pcf will be automagically translated to unicode.pf2 during the build. Assuming that your EFI partition is mounted at /boot/efi, the installation of grub is done with: grub-install --target=x86_64-efi --efi-directory=/boot/efi grub.cfg contains: set default=0 set timeout=5 insmod all_video insmod gfxterm # May be needed: insmod lvm loadfont unifont set gfxmode=1024x768 set gfxpayload=keep terminal_output gfxterm [...usual menus...] EFIShell is built in OVMF.fd, so I used that for setting the boot ordre Pierre -- http://lists.linuxfromscratch.org/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
