MBRLABEL(8) BSD System Manager's Manual MBRLABEL(8)NAME
mbrlabel -- update disk label from MBR label(s)
SYNOPSIS
mbrlabel [-fqrw] [-s sector] device
DESCRIPTION
mbrlabel is used to update a NetBSD disk label from the Master Boot Record (MBR) label(s) found on disks that were previously used on
DOS/Windows systems (or other MBR using systems).
mbrlabel scans the MBR contained in the very first block of the disk (or the block specified through the -s flag), then walks through every
extended partition found and generates additional partition entries for the disk from the MBRs found in those extended partitions.
Each MBR partition which does not have an equivalent partition in the disk label (equivalent in having the same size and offset) is added to
the first free partition slot in the disk label. A free partition slot is defined as one with an fstype of 'unused' and a size of zero
('0'). If there are not enough free slots in the disk label, a warning will be issued.
The raw partition (typically partition c, but d on i386 and some other platforms) is left alone during this process.
By default, the proposed changed disk label will be displayed and no disk label update will occur.
Available options:
-f Force an update, even if there has been no change.
-q Performs operations in a quiet fashion.
-r In conjunction with -w, also update the on-disk label.
-s sector Specifies the logical sector number that has to be read from the disk in order to find the MBR. Useful if the disk has remapping
drivers on it and the MBR is located in a non-standard place. Defaults to 0.
-w Update the in-core label if it has been changed. See also -r.

The mbrlabel command appeared in NetBSD 1.4.
