10.54. GRUB-0.97

The GRUB package contains the GRand Unified Bootloader.

10.54.1. Installation of GRUB

GRUB has an issue where it sometimes doesn't detect the disk geometry correctly when used with Linux 2.6. This results in the error message Error 24: Attempt to access block outside partition. The following patch fixes this issue:

patch -Np1 -i ../grub-0.97-disk_geometry-1.patch

This package is known to have issues when its default optimization flags (including the -march and -mcpu options) are changed. If any environment variables that override default optimizations have been defined, such as CFLAGS and CXXFLAGS, unset them when building GRUB.

Prepare GRUB for compilation:

./configure --prefix=/usr

Compile the package:

make

To test the results, issue: make check.

Install the package:

make install
mkdir -v /boot/grub
cp -v /usr/lib/grub/i386-pc/stage{1,2} /boot/grub

Replace i386-pc with whatever directory is appropriate for the hardware in use.

The i386-pc directory contains a number of *stage1_5 files, different ones for different file systems. Review the files available and copy the appropriate ones to the /boot/grub directory. Most users will copy the e2fs_stage1_5 and/or reiserfs_stage1_5 files.
