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.
