In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
The source at <file:drivers/scsi/u14-34f.c> contains some
information about this hardware. If the driver doesn't work out of
the box, you may have to change some settings in
<file: drivers/scsi/u14-34f.c>. Read the SCSI-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Note that there is also
another driver for the same hardware: "UltraStor SCSI support",
below. You should say Y to both only if you want 24F support as
well.

To compile this driver as a module, choose M here: the
module will be called u14-34f.
