Can anyone check my solution for this eprom problem. Whenever my vp-1022a vanish from the system and I'm unable to use old drivers I just power down the computer, turn power suply off and turn computer on. What it dos is dischrge all condensators in the system. After that I just switch PS on and everything goes back to normal. I dont know why but it works all the time for me. So , can anyone confirm that method ? cheers


Any help with loading the i2cdetect program when i run i2cdetect this is all that shows up

Installed I2C busses:

   i2c-0       smbus           SMBus ALI15X3 adapter at e800           Non-I2C SMBus adapter 

Am i missing something ?

In the article you say "Note: To fix the EEPROM, it is IMPORTANT that you load all modules for your 1020 card except dvb-bt8xx."

How do i load the correct modules when it won't boot...if i rename bttv.ko it does boot .

but renaming dvb-bt8xx.ko has no effect

help


Ok this is what i did and it seemed to work
