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
|
|
0 = 20 Mhz
|
|
1 = 12.2 Mhz
|
|
2 = 10 Mhz
|
|
3 = 8 Mhz
|
|
4 = 6.7 Mhz
|
|
5 = 5.8 Hhz
|
|
6 = 5 Mhz
|
|
7 = 4 Mhz
|
|
|
|
- dev_mode
|
|
Bitmap for device configuration
|
|
|
|
DevMode bit definition:
|
|
Bit Val(hex) Val(dec) Meaning
|
|
*0 0x01 1 Parity check
|
|
*1 0x02 2 Synchronous Negotiation
|
|
*2 0x04 4 Disconnection
|
|
*3 0x08 8 Send Start command on startup. (Not used)
|
|
*4 0x10 16 Tagged Command Queueing
|
|
*5 0x20 32 Wide Negotiation
|
|
|
|
- adapter_mode
|
|
Bitmap for adapter configuration
|
|
|
|
AdaptMode bit definition
|
|
Bit Val(hex) Val(dec) Meaning
|
|
*0 0x01 1 Support more than two drives. (Not used)
|
|
*1 0x02 2 Use DOS compatible mapping for HDs greater than 1GB.
|
|
*2 0x04 4 Reset SCSI Bus on startup.
|
|
*3 0x08 8 Active Negation: Improves SCSI Bus noise immunity.
|
|
4 0x10 16 Immediate return on BIOS seek command. (Not used)
|
|
(*)5 0x20 32 Check for LUNs >= 1.
|
|
|
|
- tags
|
|
Default: 3, Acceptable values: 0-5
|
|
|
|
The number of tags is 1<<x, if x has been specified
|
|
|
|
- reset_delay
|
|
Default: 1, Acceptable values: 0-180
|
|
|
|
The seconds to not accept commands after a SCSI Reset
|
|
|
|
|
|
For the built in driver the parameters should be prefixed with
|
|
dc395x. (eg "dc395x.safe=1")
