Yeah, loopback should be used to boot by loading from the filesystem. So if it is a GNU/Linux CDROM you can just load the kernel. But in that case the distribution should also understand this feature somehow and mount the loopback image as well. The problems with chainloading is that this might work differently for CDROMs. One thing is that you have to read 2048 bytes instead of 512. Besides that, the code in this sector is not enough to boot the CDROM usually and the boot code will not find the CDROM, because it is not in the CDROM drive. So in your case this feature is not as useful as it seemed to be, I think. -- Marco _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
