+We RTEMS in QEMU by first booting from a floppy disk image. You can use the image we have made by downloading it from the RTEMS ftp server. The following instructions built the image and were run on a Fedora Core 5 Linux host.
 
-http://grub.enbug.org/TestingOnX86
+Download the latest release of version 2 the [http://grub.enbug.org/FrontPage Grub boot loader] from [ftp://alpha.gnu.org/gnu/grub/]. Build the package with the following configure command:
+
+  $ ../grub-1.94/configure --prefix=/tmp/g2/build
+  $ make all install
+
+where the prefix can be anything suitable for your machine. If configure fails with a missing LZO library check you have the lzo-devel package installed.
+
+To make the floppy image follow the instructions in the Grub Wiki at http://grub.enbug.org/TestingOnX86. This script is adapted from the instructions:
+
+ #! /bin/sh -x
+ grub=/tmp/g2/build
+ workspace=/tmp/g2
+ mnt=$workspace/mnt/loop
+ file=$workspace/rtems-boot.img
+ export PATH=$grub/bin:$grub/sbin:$PATH
+ mkdir -p $workspace
+ cd $workspace
+ grub-mkimage -o core.img _chain fat
+ dd if=/dev/zero of=$file bs=512 count=2880
+ /sbin/mkdosfs $file
+ mkdir -p $mnt
+ mount -o loop -t vfat $file $mnt
+ mkdir -p $mnt/boot/grub
+ cp $grub/lib/grub/i386-pc/boot.img core.img $grub/lib/grub/i386-pc/*.mod $mnt/boot/grub
+ test -f grub.cfg && cp -f grub.cfg $mnt/boot/grub
+ echo '(fd0)' $file > tmp_device.map
+ grub-setup -d $mnt/boot/grub -r '(fd0)' -m tmp_device.map '(fd0)'
+ rm -f tmp_device.map
+ umount $mnt
