GNU GRUB is a Multiboot boot loader. It was derived from
|
||||
GRUB, the GRand Unified Bootloader, which was originally
|
||||
designed and implemented by Erich Stefan Boleyn. GRUB 2 has
|
||||
replaced what was formerly known as GRUB (i.e. version
|
||||
0.9x), which has, in turn, become GRUB Legacy.
|
||||
|
||||
Amongst others, GRUB2 offers EFI support, which GRUB Legacy
|
||||
doesn't provide.
|
||||
|
||||
Notes on using Grub2 for BIOS-based platforms
|
||||
=============================================
|
||||
|
||||
1. Create a disk image
|
||||
dd if=/dev/zero of=disk.img bs=1M count=32
|
||||
2. Partition it (either legacy or GPT style partitions work)
|
||||
cfdisk disk.img
|
||||
- Create one partition, type Linux, for the root
|
||||
filesystem. The only constraint is to make sure there
|
||||
is enough free space *before* the first partition to
|
||||
store Grub2. Leaving 1 MB of free space is safe.
|
||||
3. Setup loop device and loop partitions
|
||||
sudo losetup -f disk.img
|
||||
sudo partx -a disk.img
|
||||
4. Prepare the root partition
|
||||
sudo mkfs.ext3 -L root /dev/loop0p1
|
||||
sudo mount /dev/loop0p1 /mnt
|
||||
sudo tar -C /mnt -xf output/images/rootfs.tar
|
||||
sudo umount /mnt
|
||||
5. Install Grub2
|
||||
./output/host/usr/sbin/grub-bios-setup \
|
||||
-b ./output/host/usr/lib/grub/i386-pc/boot.img \
|
||||
-c ./output/images/grub.img -d . /dev/loop0
|
||||
6. Your disk.img is ready!
|
||||
|
||||
To test your BIOS image in Qemu:
|
||||
|
||||
qemu-system-{i386,x86-64} -hda disk.img
|
||||
|
||||
Notes on using Grub2 for EFI-based platforms
|
||||
============================================
|
||||
|
||||
1. Create a disk image
|
||||
dd if=/dev/zero of=disk.img bs=1M count=32
|
||||
2. Partition it with GPT partitions
|
||||
cgdisk disk.img
|
||||
- Create a first partition, type EF00, for the
|
||||
bootloader and kernel image
|
||||
- Create a second partition, type 8300, for the root
|
||||
filesystem.
|
||||
3. Setup loop device and loop partitions
|
||||
sudo losetup -f disk.img
|
||||
sudo partx -a /dev/loop0
|
||||
4. Prepare the boot partition
|
||||
sudo mkfs.vfat -n boot /dev/loop0p1
|
||||
sudo mount /dev/loop0p1 /mnt
|
||||
sudo cp -a output/images/efi-part/* /mnt/
|
||||
sudo cp output/images/bzImage /mnt/
|
||||
sudo umount /mnt
|
||||
5. Prepare the root partition
|
||||
sudo mkfs.ext3 -L root /dev/loop0p2
|
||||
sudo mount /dev/loop0p2 /mnt
|
||||
sudo tar -C /mnt -xf output/images/rootfs.tar
|
||||
sudo umount /mnt
|
||||
6 Cleanup loop device
|
||||
sudo partx -d /dev/loop0
|
||||
sudo losetup -d /dev/loop0
|
||||
7. Your disk.img is ready!
|
||||
|
||||
To test your EFI image in Qemu:
|
||||
|
||||
1. Download the EFI BIOS for Qemu
|
||||
Version IA32 or X64 depending on the chosen Grub2
|
||||
platform (i386-efi vs. x86-64-efi)
|
||||
http://sourceforge.net/projects/edk2/files/OVMF/
|
||||
2. Extract, and rename OVMF.fd to bios.bin and
|
||||
CirrusLogic5446.rom to vgabios-cirrus.bin.
|
||||
3. qemu-system-{i386,x86-64} -L ovmf-dir/ -hda disk.img
|
||||
4. Make sure to pass pci=nocrs to the kernel command line,
|
||||
to workaround a bug in the EFI BIOS regarding the
|
||||
EFI framebuffer.
