The current I2C-Code could by accident overwrite the configuration EEPROM on 
Hauppauge boards!!! 
(E.g. the videotext driver and the bt848 driver do not know about each other.
This might cause unwanted states on the I2C bus which overwrite the EEPROM)

Back up this EEPROM before doing anything else by typing:
(do this AFTER installing bttv.o with "make ins" but BEFORE starting the
X application)

make readee
readee > tvee.h

If you encounter any problems in Windows95 (like "PNP component not found" ...)
go back into linux, load bttv and type:

make writeee
writeee

to write the backed up contents.
If you backed up your EEPROM as described above, this will restore it to its
original state.
A detailed description of the meaning of the EEPROM bytes by
Hauppauge would of course be even more helpful! 

If you have board type 405 and you did not make a backup, my tvee.h file in 
mytvee.h might be of help.

Forget about all of the above if you do not have a Hauppauge board.
