+ ****************************************************************
+ * This driver supports the Adaptec I2O RAID and DPT SmartRAID V I2O boards.
+ *
+ * CREDITS:
+ * The original linux driver was ported to Linux by Karen White while at 
+ * Dell Computer.  It was ported from Bob Pasteur's (of DPT) original 
+ * non-Linux driver.  Mark Salyzyn and Bob Pasteur consulted on the original
+ * driver. 
+ * 
+ * 2.0 version of the driver by Deanna Bonds and Mark Salyzyn.
+ *
+ * HISTORY:
+ * The driver was originally ported to linux version 2.0.34 
+ *
+ * V2.0 Rewrite of driver.  Re-architectured based on i2o subsystem.
+ *   This was the first full GPL version since the last version used
+ *   i2osig headers which were not GPL.  Developer Testing version.
+ * V2.1 Internal testing
+ * V2.2 First released version
+ *
+ * V2.3 
+ *   Changes:
+ *      Added Raptor Support
+ *      Fixed bug causing system to hang under extreme load with 
+ *         management utilities running (removed GFP_DMA from kmalloc flags)
+ *
+ *
+ * V2.4 First version ready to be submitted to be embedded in the kernel
+ *   Changes: 
+ *      Implemented suggestions from Alan Cox
+ *      Added calculation of resid for sg layer
+ *      Better error handling
+ *         Added checking underflow condtions 
+ *         Added DATAPROTECT checking
+ *         Changed error return codes
+ *         Fixed pointer bug in bus reset routine
+ *      Enabled hba reset from ioctls (allows a FW flash to reboot and use the new
+ *         FW without having to reboot)
+ *      Changed proc output
+ *
+ * TODO:
+ *      Add 64 bit Scatter Gather when compiled on 64 bit architectures
+ *      Add sparse lun scanning 
+ *      Add code that checks if a device that had been taken offline is
+ *         now online (at the FW level) when test unit ready or inquiry 
+ *         command from scsi-core
+ *      Add proc read interface
+ *         busrescan command
+ *         rescan command
+ *      Add code to rescan routine that notifies scsi-core about new devices
+ *      Add support for C-PCI (hotplug stuff)
+ *      Add ioctl passthru error recovery
+ *
+ * NOTES:
+ * The DPT card optimizes the order of processing commands.  Consequently,
+ * a command may take up to 6 minutes to complete after it has been sent
+ * to the board.  
+ *
+ * The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the
+ * interface files for Adaptec's management routines.  These define the structures used
+ * in the ioctls.  They are written to be portable.  They are hard to read, but I need
+ * to use them 'as is' or I can miss changes in the interface.
