+README file for the dc395x SCSI driver
+======================================
+
+Status
+------
+The driver has been tested with CD-R and CD-R/W drives. These should
+be safe to use. Testing with hard disks has not been done to any
+great degree and caution should be exercised if you want to attempt
+to use this driver with hard disks.
+
+This is a 2.5 only driver. For a 2.4 driver please see the original
+driver (which this driver started from) at
+http://www.garloff.de/kurt/linux/dc395/
+
+Problems, questions and patches should be submitted to the mailing
+list. Details on the list, including archives, are available at
+http://lists.twibble.org/mailman/listinfo/dc395x/
+
+Parameters
+----------
+The driver uses the settings from the EEPROM set in the SCSI BIOS
+setup. If there is no EEPROM, the driver uses default values.
+Both can be overridden by command line parameters (module or kernel
+parameters).
+
+The following parameters are available:
+
+safe
+ Default: 0, Acceptable values: 0 or 1
+
+ If safe is set to 1 then the adapter will use conservative
+ ("safe") default settings. This sets:
+
+ shortcut for dc395x=7,4,9,15,2,10
+
+adapter_id
+ Default: 7, Acceptable values: 0 to 15
+
+ Sets the host adapter SCSI ID.
+
+max_speed
+ Default: 1, Acceptable value: 0 to 7

DCCP PROTOCOL
This driver works, but is still in experimental status. So better
have a bootable disk and a backup in case of emergency.
- Documentation can be found in <file:Documentation/scsi/dc395x.txt>.
+ Documentation can be found in <file:Documentation/scsi/dc395x.rst>.
To compile this driver as a module, choose M here: the
module will be called dc395x.
