The range of sectors that should be mapped, has to be specified. Either a range ( start- end) or a start and a distance ( start+ number) have to be specified. start and end are zero-based. If only the start is specified, only that sector is mapped.
The image is specified as follows: image= device_name Additionally, the range variable must be set.
Example:
image = /dev/fd0 range = 1+512
