BusyBox v1.22.1 static (2014-04-06 21:24 +0200) multi-call binary.

Usage: fdisk [-ul] [-C CYLINDERS] [-H HEADS] [-S SECTORS] [-b SSZ] DISK

Change partition table

-u Start and End are in sectors (instead of cylinders)
-l Show partition table for each DISK, then exit
-b 2048 (for certain MO disks) use 2048-byte sectors
-C CYLINDERS Set number of cylinders/heads/sectors
-H HEADS
-S SECTORS
