XCVR value read from the EEPROM is completely wrong. I've had one report
of a 3c900 card that returns an xcvr value of 14, which is impossible
(the manual states that all vales above 8 are reserved). If the value
is out of the expe
Add PCI vendor ID for the 3c980-TX server adapter card, which apparently
also uses the cyclone chip. Graciously supplied Mats O Jansson
<maja@cntw.com>.
Also noted by Mats, the 10mpbs cyclone adapters should be named 3c900B,
not 3c905B. I haven't actually encountered a 10mbps only cyclone adapter
yet, nor anybody who has one, but this makes sense given the naming
scheme used for the older boomerang adapters.

Recent versions of 3.0-current have the bktr driver built in. Older versions
of 3.0 and all versions of 2.2 need to have the driver files installed by hand:
cp ioctl_bt848.h /sys/i386/include/
cp brktree_reg.h brooktree848.c /sys/pci/
In /sys/conf/files add:
pci/brooktree848.c optional bktr device-driver
-------------------------------------------------------------------------------
In all cases you will need to add the driver to your kernel:
In your kernel configuration file:
controller pci0 #if you already have this line don't add it.
device bktr0
There is no need to specify DMA channels nor interrupts for this
driver.
-------------------------------------------------------------------------------
Finally you need to create nodes for the driver:
Create a video device:
mknod /dev/bktr0 c 92 0
Create a tuner device:
mknod /dev/tuner0 c 92 16
-------------------------------------------------------------------------------
The code attempts to auto-probe code to detect card/tuner types.
The detected card is printed in the dmesg as the driver is loaded. If
this fails to detect the proper card you can override it in brooktree848.c:
#define OVERRIDE_CARD <card type>
where <card type> is one of:
CARD_UNKNOWN
CARD_MIRO
CARD_HAUPPAUGE
CARD_STB
CARD_INTEL
-------------------------------------------------------------------------------
This model now separates the "tuner control" items into a minor device:
minor device layout: xxxxxxxx xxxT UUUU
UUUU: the card (ie UNIT) identifier, 0 thru 15
T == 0: video device
T == 1: tuner device
Access your tuner ioctl thru your tuner device handle and anything
which controls the video capture process thru the video device handle.
Certain ioctl()s such as video source are available thru both devices.
-------------------------------------------------------------------------------
If your tuner does not work properly or is not recognized properly
try setting the tuner type via or card type:
sysctl -w hw.bt848.card=<integer> current valid values are 0 to 5 inclusive
sysctl -w hw.bt848.tuner=<integer> where integer is a value from 1 to 10
systcl -w hw.bt848.reverse_mute=<1 | 0> to reverse the mute function in the
driver set variable to 1.
The exact format of the sysctl bt848 variable is:
unit << 8 | value
unit identifies the pci bt848 board to be affected 0 is the first bt848
board, 1 is the second bt848 board.
value denotes the integer value for tuners is a value from 0 to 10 for
reversing the mute function of the tuner the value is 1 or 0.
to find out all the bt848 variables:
sysctl hw.bt848
-------------------------------------------------------------------------------
The bt848 driver consists of:
src/sys/i386/include/ioctl_bt848.h
src/sys/pci/brktree_reg.h
src/sys/pci/brooktree848.c
