53C810 non 'A', 53C815 and 53C825 non 'A' are now attached by the driver (by default). The driver uses a different SCRIPTS set based on MEMORY MOVE instructions for these chips. 2 SCRIPTS sets (firmwares) numbered #1 and #2 are used for the whole support of the 53C8XX family to get possible: - FW #1 : Only based on MEMORY MOVE instructions. Selected for 810, 815, 825. - FW #2 : LOAD/STORE based. This is the firmware also used by previous driver versions. Selected for other chips. When both `ncr' and `sym' are configured, `sym' will now attach all the 53C8XX devices by default. Previous balancing between `ncr' and `sym' can be preserved by: - Either editing sym_conf.h and commenting the following compile option: #define SYM_CONF_GENERIC_SUPPORT (This also saves about 3.5Kb of kernel memory). - Or setting kernel config option SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40)

* Device driver optimized for the Symbios/LSI 53C896/53C895A/53C1010

* PCI-SCSI controllers.

* Copyright (C) 1999-2000 Gerard Roudier <groudier@club-internet.fr>
|
|
*
|
|
* This driver also supports the following Symbios/LSI PCI-SCSI chips:
|
|
* 53C810A, 53C825A, 53C860, 53C875, 53C876, 53C885, 53C895,
|
|
* 53C810, 53C815, 53C825 and the 53C1510D is 53C8XX mode.
|
|
*
|
|
*
|
|
* This driver for FreeBSD-CAM is derived from the Linux sym53c8xx driver.

|
* Copyright (C) 1998-1999 Gerard Roudier
|
|
*
|
|
* The sym53c8xx driver is derived from the ncr53c8xx driver that had been
|
|
* a port of the FreeBSD ncr driver to Linux-1.2.13.
|
|
*
|
|
* The original ncr driver has been written for 386bsd and FreeBSD by
|
|
* Wolfgang Stanglmeier <wolf@cologne.de>

* Stefan Esser <se@mi.Uni-Koeln.de>

|
* Copyright (C) 1994 Wolfgang Stanglmeier
|
|
*
|
|
* The initialisation code, and part of the code that addresses
|
|
* FreeBSD-CAM services is based on the aic7xxx driver for FreeBSD-CAM
|
|
* written by Justin T. Gibbs.
