Hi. I'm having problem to boot my own multiboot-compliant kernel from a
CD/DVD. Using GRUB2 1.98 I did this:
grub-mkimage -p /boot -o core.img -O i386-pc biosdisk iso9660 multiboot
configfile
cat /usr/lib/grub/i386-pc/cdboot.img core.img > eltorito.img
then I prepared a directory like this:
/
boot/
grub/
eltorito.img
grub.cfg
kernel.sys
And using mkisofs specifing eltorito.img as boot image and other parameters
I was able to boot my kernel. However with 1.99rc1 this doesn't seem to work
anymore.
I always end up to the grub shell (not the rescue one). Playing a bit with
commands, what I came to the conclusion that, even though I put the iso9660
module in grub-mkimage grub isn't able to read the filesystem. The multiboot
command always says "error: couldn't open file" and "ls (cd)" says "error:
bad filename".
Any suggestion?

So only "ls (cd)/" would work. > > Any suggestion? > > > _______________________________________________ > Grub-devel mailing list > Grub-devel@gnu.org > http://lists.gnu.org/mailman/listinfo/grub-devel > -- Regards Vladimir 'φ-coder/phcoder' Serbinenko [-- Attachment #2: OpenPGP digital signature --] [-- Type: application/pgp-signature, Size: 294 bytes --] ^ permalink raw reply [flat|nested] 2+ messages in thread
