In CentOS 5.0, you can get board temperature in dmesg.

#dmesg | grep Thermal

About board voltage,use lm-sensors to find.

#yum install lm_sensors.i386 lm_sensors-dev.i386

You will got asynchronous image when you load Bttv driver for BT878 capture function,
It was Bttv driver bug cause of the error image
Because Bttv driver can't auto-switch the BT878 register when you change to PAL model

Thereby We should configure bttv driver correct parameter,Please follow the below procedure to done!!

• Remove the Bttv driver
  

#rmmod bttv 
 

• Reload the Bttv driver and provide the correct parameter for PAL
  

#modprobe bttv pll=1,1,1,1

• Run your capture application ,for example we used the xawtv

#xawtv

• Select the PAL model
