GRUB2

Introduction

Our long term goal is to replace the common LinuxBIOS payload FILO with a LinuxBIOS-capable version of GRUB2.

Status

Patrick Georgi has been working on GRUB2 for LinuxBIOS during the Google Summer of Code 2007.

Find his code here:

• http://linuxbios.org/~oxygene/lbgrub2-20070820-1.tar.bz2

Todo

• Fix lbgrub2 for LinuxBIOS v2
  • GRUB2's grub-mkimage needs to put the program headers right after the elf header (Fix available).
• USB stack integration
• Fix larfs to reflect latest changes
• export console device in linuxbios table and read this entry in grub2.
• See more information at http://tracker.linuxbios.org/trac/LinuxBIOS/milestone/Port%20GRUB2%20to%20LinuxBIOS

How to build GRUB2 as a payload

$ # build lbgrub2:
$ # target/target_alias assume that you use i386-elf-gcc
$ configure --with-platform=linuxbios --prefix=$PWD/installed 
$ make && make install
$ $PWD/installed/bin/grub-mkimage -o core.img normal fat iso9660 ext2 pc atadisk rom lar ls cat cmp hello help serial terminal test configfile multiboot boot loopback
