This driver is based on linux bttv driver.
In it's current state it supports only radio with Hauppauge TV-Cards.
But it should be able to detect TV-Cards without radio support.
Requirements
============
Currently you need OS/2 Warp 4 with fixpack #13 or higher or eCS.
A TV-Grabber card (see DOC\CARDLIST for a list of supported cards)
Installation
============
Install LXAPI32.SYS first !!! Then reboot the machine. If the system comes up
you can install BT32.SYS AFTER LXAPI32.SYS.
BT32.SYS can currently coexist with WCAST.SYS driver from abbotsbury.
But it needs to be loaded first. So place the DEVICE=X:\MMOS2\BT32.SYS line somewhere above the X:\MMOS2\WCAST.SYS line
If you want to see some information, you may try the following parameters:
/V Verbose: Show Copyright information and detected card(s)
/VM Verbose modules: Like /V plus module list
/3 Debug: execute an INT3 at initialisation (Use kernel debugger !)
/NOMODULE Don't load modules at system startup (Use BT32CFG.EXE to load/unload)
/NOCOREMODULE Don't load core modules at system startup (Use BT32CFG.EXE to load/unload)
/MODPARM: Support Linux insmod parameters for various modules.
/MODPARM:
=========
The syntax for /MODPARM: is:
/MODPARM:[module]:[parm1][;parm2][...]
See Insmod-options in the DOC directory for parameters.
Example:
To specify that card0 is a Hauppauge (bt878) and it should use the
Philips PAL_I tuner and the size of the number of capture buffers should be 4
you can specify:
/MODPARM:bttv:card0=10;tuner0=1;gbuffers=4
Note: Insmod-Options are only supported for
bttv
tuner
msp3400
tda7432
As an alternative you can use BT32CFG to set options. You should unload
the module before you change options.
Sorry, this is very complicate for now. I'll try to make the driver stable and
then produce a good documentation.
Technology
==========
The LXAPI32.SYS is a common linux services driver. It provides functions for
PCI,I2C,memory,resources with linux function calls. BT32.SYS contains only the
code needed for the TV-Card. This provides more flexibility and it may be easy
to port other drivers from linux with this common LXAPI32.SYS.
Using the driver
================
Included in this package is a small radio app. It is a very short hack and will
be extended when the driver supports all other planned things.
Future
======
I plan to implement TV and VBI (Teletext) into the driver.
This may take some time.
Reporting problems
==================
If your machine traps on boot or while using the radio app, please write down
all register information and send it to me.
If it installs successfully it would be nice to hear from you if the radio app
is working.
At initialisation the driver reports a list of "modules" it has loaded. Please
include this list in your problem report.
Also it would be nice if you can tell me, if radio is working, when module
TDA7432 or module TDA9875 is loaded, because i don't have those chips.
Report all problems to s.milcke@nord-com.net with subject BT32
