I posted the following on grub-devel before I realized that this was the better list for it...
We are booting from a CD which needs to forward to a bootable hard drive (if possible). The hard drive might be SATA, might be IDE. My current menu.lst looks something like this: ######################################### timeout 10 default 0 fallback 1 2 title boot from SATA drive root (hd0,0) kernel /vmlinuz root=/dev/sda2 panic=5 boot title boot from IDE drive root (hd0,0) kernel /vmlinuz root=/dev/hda2 panic=5 boot title Boot from CD root (cd) kernel /boot/vmlinuz root=/dev/ram0 init=/linuxrc initrd /boot/initrd.img boot ######################################### The only difference between entries 0 and 1 is in the "root=/dev/?da2". If we were booting from writable media, we could use "default savedefault" and "savedefault fallback" commands to chain from one entry to the other after a kernel panic. Unfortunately, that's not the situation. As it is this menu.lst works with SATA drives but not with PATA or IDE drives. I can switch this around by reordering the entries (or modifying default and fallback) but I can't seem to get Is there a way for grub to substitute the correct /dev/* depending on whether the drive is SATA or not? Even better would be a way to make this work when booting from a CD: ######################################### timeout 10 default 0 fallback 1 title boot from hard drive rootnoverify (hd0) chainloader +1 title Boot from CD root (cd) kernel /boot/vmlinuz root=/dev/ram0 init=/linuxrc initrd /boot/initrd.img boot ######################################### Can this be made to work? If so, what am I missing? Thanks, Russel Hill _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub
