I needed a grub-0.92, with a patch from <http://alpha.polynum.org/misc/>, and version 1.16 of mkbimage (I don't exactly remember where I got that from). + +You can grab a copy of it at <http://sleepingsquirrel.org/hurd/hurdcd.iso.gz>, which is a gzipped bootable \*.iso with the copy of the patched grub and the version of mkbimage I used.

If you use the `-t hd` switch of `mkbimage`, you'll get an ext2fs El-Torito HD emulation image that can be any size (I've got one here 300+ MB). You can then use `root (hd0,0)` in Grub to boot something. Also, invoking `mkbimage` with no parameters will give you some additional help messages. + +-- [[Main/GregBuchholz]] - 05 Nov 2003 + +## <a name="Another_recipe_for_a_bootable_GN"> </a> Another recipe for a bootable GNU CD + +[screenshot](http:///mycelium.afraid.org/Screenshot2.png) + +### <a name="What_you_ll_need"> What you'll need </a> + +* A [stage2\_eltorito](http://mycelium.dyndns.org/stage2_eltorito) from [grub 0.95](http://www.gnu.org/software/grub) +* A [base system](http://www.update.uu.se/~ams/gnu/gnu-2004-12-04.tar.bz2) +* [iso9660fs.static](http:///mycelium.dyndns.org/iso9660fs.static) or just build your own, it should work with CVS + +### <a name="Know_HowTo"> </a> [[Know/HowTo]] + + # mkdir iso + ..(at this point untar or setup base system) + # mkdir -p iso/boot/grub + # cp iso9660fs.static iso/hurd + # cp stage2_eltorito iso/boot/grub + ..(edit iso/boot/grub/grub.conf) + # mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot \ + -boot-load-size 4 -boot-info-table -o livecd.iso iso/ + +**_Note:_** The following files must **\_NOT\_** be symlinks! + +* `/boot/gnumach` +* `/hurd/iso9660fs.static` +* `/hurd/exec` +* `/lib/ld.so.1` + +## <a name="Contents_of_grub_conf"> Contents of grub.conf </a> + + timeout 60 + default 0 + + title GNU/Hurd CD + #uppermem 523648 #this may need to be set + #root (cd) + kernel /boot/gnumach root=device:hd2 #set device to your cdrom device + module /hurd/iso9660fs.static --multiboot-command-line=${kernel-command-line} \ + --host-priv-port=${host-port} --device-master-port=${device-port} \ + --exec-server-task=${exec-task} -T typed ${root} $(task-create) \ + $(task-resume) + module /lib/ld.so.1 /hurd/exec $(exec-task=task-create) + +**_Note:_** The `root (cd)` line may prevent some computers from booting the livecd. + +-- [[Main/AndrewResch]] - 22 Feb 2005 |
