<p class="Pp">This driver provides access to the VIA chipset Power Management
    Unit family. They are VT82C586B, VT82C596A, VT82C596B, VT82C686A and
  VT8233.</p>
<p class="Pp">The embedded controller of the VIA chipset may give you access to
    the monitoring facilities of your mainboard.</p>
<p class="Pp">The 586B support is made by software whereas other controllers
    support the SMBus protocol by hardware. See <a class="Xr">smb(4)</a> for
    writing user code to fetch voltages, temperature and so on from the
    monitoring chip of your mainboard.</p>
