+ exclusive use. For a layman this model can be described as similar to

host adapter with one dummy SCSI disk. Each dummy disk uses kernel
RAM as storage (i.e. it is a ramdisk). To save space when multiple
dummy disks are simulated, they share the same kernel RAM for
- their storage. See <http://www.torque.net/sg/sdebug.html> for more
+ their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
information. This driver is primarily of use to those testing the
SCSI and block subsystems. If unsure, say N.
