What is the basic function of video card BIOS and sound card BIOS ? what is the difference it with cpu BIOS ?
 

video BIOs is for the video related BIOS driver.

sound BIOS is its own BIOS driver.(ie, sound related routines)

the cpu BIOS , i think you are referring to the sytemboard BIOS(BIOS ROM) , contains drivers at BIOS level for all other devices.
like , Keyboard , serial , parallel port etc.
