In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
These are 8-bit SCSI controllers; the ST-01 is also supported by
this driver. It is explained in section 3.9 of the SCSI-HOWTO,
available from <http://www.tldp.org/docs.html#howto>. If it
doesn't work out of the box, you may have to change some macros at
compiletime, which are described in <file:drivers/scsi/seagate.c>.

To compile this driver as a module, choose M here: the
module will be called seagate.
