-AACRAID Driver for Linux (take two)
-
-Introduction
--------------------------
-The aacraid driver adds support for Adaptec (http://www.adaptec.com)
-RAID controllers. This is a major rewrite from the original
-Adaptec supplied driver. It has signficantly cleaned up both the code
-and the running binary size (the module is less than half the size of
-the original).

-People
--------------------------
-Alan Cox <alan@redhat.com>
-Christoph Hellwig <hch@infradead.org> (updates for new-style PCI probing and SCSI host registration,
- small cleanups/fixes)
-Matt Domsch <matt_domsch@dell.com> (revision ioctl, adapter messages)
-Deanna Bonds (non-DASD support, PAE fibs and 64 bit, added new adaptec controllers
- added new ioctls, changed scsi interface to use new error handler,
- increased the number of fibs and outstanding commands to a container)
-
- (fixed 64bit and 64G memory model, changed confusing naming convention
- where fibs that go to the hardware are consistently called hw_fibs and
- not just fibs like the name of the driver tracking structure)
-Mark Salyzyn <Mark_Salyzyn@adaptec.com> Fixed panic issues and added some new product ids for upcoming hbas.
-
-Original Driver
--------------------------
-Adaptec Unix OEM Product Group
-
-Mailing List
--------------------------
-linux-scsi@vger.kernel.org (Interested parties troll here)
-Also note this is very different to Brian's original driver
-so don't expect him to support it.
-Adaptec does support this driver. Contact either tech support or Mark Salyzyn.
