config SCSI_AIC7XXX_OLD
tristate "Adaptec AIC7xxx support (old driver)"
depends on (ISA || EISA || PCI ) && SCSI
help
WARNING This driver is an older aic7xxx driver and is no longer
under active development. Adaptec, Inc. is writing a new driver to
take the place of this one, and it is recommended that whenever
possible, people should use the new Adaptec written driver instead
of this one. This driver will eventually be phased out entirely.
This is support for the various aic7xxx based Adaptec SCSI
controllers. These include the 274x EISA cards; 284x VLB cards;
2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
motherboard based SCSI controllers from Adaptec. It does not support
the AAA-13x RAID controllers from Adaptec, nor will it likely ever
support them. It does not support the 2920 cards from Adaptec that
use the Future Domain SCSI controller chip. For those cards, you
need the "Future Domain 16xx SCSI support" driver.
In general, if the controller is based on an Adaptec SCSI controller
chip from the aic777x series or the aic78xx series, this driver
should work. The only exception is the 7810 which is specifically
not supported (that's the RAID controller chip on the AAA-13x
cards).
Note that the AHA2920 SCSI host adapter is *not* supported by this
driver; choose "Future Domain 16xx SCSI support" instead if you have
one of those.
Information on the configuration options for this controller can be
found by checking the help file for each of the available
configuration options. You should read
<file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
contacting the maintainer with any questions. The SCSI-HOWTO,
available from <http://www.tldp.org/docs.html#howto>, can also
be of great help.
To compile this driver as a module, choose M here: the
module will be called aic7xxx_old.
