You can also specify the geometry manually with the following command
line options (currently untested):
- c=<number> Specify number of cylinders
- h=<number> Specify number of heads
- s=<number> Specify number of sectors
+ c=<number> Specify number of cylinders (max 1024[*])
+ h=<number> Specify number of heads (max 256[*])
