I have looked at this problem deeply, and I think the following changes would be required: - A variable to specify where grub.cfg and modules are present. Currently, we have it only for a prefix without a drive. So grub_root_drive or something must be added. It could be added to kern/i386/pc/startup.S, but boot/i386/pc/boot.S might be more appropriate (if there is space large enough). - grub-setup must handle a root drive independently, of a boot drive or an embedding drive. - kern/i386/pc/init.c must be modified accordingly. The scinarii would be the following: - If a core image is embedded, and a grub directory is in the same drive, all drives should be set to -1, thus a boot drive passed by BIOS or another boot loader will be used. - If a core image is embedded, and a grub directory is in a different drive, a root drive must be explicitly set by grub-setup. The other drives will be set by BIOS or another boot loader. - If a core image is not embedded, and it is in the same drive, the same as the first example. - If a core image is not embedded, and it is in a different drive, an embedding drive is identical to a root drive, and must be set explicitly by grub-setup. I am planning to fix it myself, but if I look too slow, please feel free to fix it instead of me.
