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

- 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

- Or setting kernel config option

ray_sj now checks to see if any of the parameters it can update can be

ray_sj_done now updates parameters to the current n/w set if we changed

ray_stop, ray_unload and ray_reset are currently broken - reset isn't used anyway.
ray_tx_XXX and ray_rx only have cosmetic changes.

Another significant change in this driver version applies
to the checking of the data direction. The driver is now

the device changes to the wrong direction during the IO.
This driver version is still usable under FreeBSD 3.2/3.3,
since it only requires CAM, other kernel interface dependencies
being #if'ed in the sources according to kernel version.
But, in order to use the driver under those early kernel
versions, user has to move the driver sources by hand and make
appropriate tiny changes to let the kernel know about the driver.
