Grub issue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While going through some grub-docs I found a grub command "device". It should be used to map a drive to something else, e.g. a file that would then be mapped as a drive. This is parallel to the loopback mechanism of Linux.

I then got the idea that it should be possible with this to boot from a file-image of a boot diskette. But trying this I got stuck because the device option is only available in the grub-program not in the boot shell.

Now two questions come up:
- What is the use of the device command to map a file as a drive?
- Can grub boot from a file-image of a bootdisk as if the diskimage was on a disk in the first disk-drive?
