drivemap

Command

drivemap -l|-r|[-s] from_drive to_drive

Without options, map the drive from_drive to the drive to_drive. This is necessary when you chain-load some operating systems, such as DOS, if such an OS resides at a non-first drive. For convenience, any partition suffix on the drive is ignored, so you can safely use ${root} as a drive specification.

With the -s option, perform the reverse mapping as well, swapping the two drives.

With the -l option, list the current mappings.

With the -r option, reset all mappings to the default values.

For example:

drivemap -s (hd0) (hd1)
