SCSI subsystem documentation
============================

The Linux Documentation Project (LDP) maintains a document describing
the SCSI subsystem in the Linux kernel (lk) 2.4 series. See:
http://www.tldp.org/HOWTO/SCSI-2.4-HOWTO . The LDP has single
and multiple page HTML renderings as well as postscript and pdf.
It can also be found at:

Notes on using modules in the SCSI subsystem

your options, we should first define a few terms.

will enforce the correct ordering of loading and unloading modules in
the SCSI subsystem.

and then unload it once you have no further need for the driver (and release
the associated memory).

The lower level drivers are the ones that support the individual cards that
are supported for the hardware platform that you are running under. Those
individual cards are often called Host Bus Adapters (HBAs). For example the
-aic7xxx.o driver is used to control all recent SCSI controller cards from
-Adaptec. Almost all lower level drivers can be built either as modules or
