If you want to use SCSI hard disks, Fibre Channel disks,
Serial ATA (SATA) or Parallel ATA (PATA) hard disks,
USB storage or the SCSI or parallel port version of
the IOMEGA ZIP drive, say Y and read the SCSI-HOWTO,
the Disk-HOWTO and the Multi-Disk-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. This is NOT for SCSI
CD-ROMs.

To compile this driver as a module, choose M here and read
<file:Documentation/scsi/scsi.rst>.
The module will be called sd_mod.

Do not compile this driver as a module if your root file system
(the one containing the directory /) is located on a SCSI disk.
In this case, do not compile the driver for your SCSI host adapter
(below) as a module either.
