/OVERRIDE=keyword
When used with the keyword GEOMETRY, this operation overrides
the FAT12 disk volume geometry requirement check. So long as
the FAT12 volume matches the FAT12 volume size requirements, the
volume structures will be initialized using the designated FAT12
geometry requirements values.
The geometry reported by the target device will not be altered.
To subsequently MOUNT the volume, see MOUNT/OVERRIDE=GEOMETRY.
