DESCRIPTION

       This  driver  provides  access  to  the  VIA  chipset  Power Management Unit family.  They are VT82C586B,
       VT82C596A, VT82C596B, VT82C686A and VT8233.

       The embedded controller of the VIA chipset may give you access  to  the  monitoring  facilities  of  your
       mainboard.

       The  586B  support  is made by software whereas other controllers support the SMBus protocol by hardware.
       See smb(4) for writing user code to fetch voltages, temperature and so on from  the  monitoring  chip  of
       your mainboard.
