Hello friennd,

Every motherboard have hardware monitoring chip and its generally connected to either SMBUS(like i2c) or ISA.

My PC has cheap W83627EHF and its connected with PC's LPC bus and from data sheet they write " The first interface uses LPC Bus to access which the ports of low byte (bit2~bit0) are defined in the port 5h
and 6h. The other higher bits of these ports is set by W83627EHF itself. The general decoded address is
set to port 295h and port 296h. These two ports are described as following:
Port 295h: Index port.
Port 296h: Data port. "


I try to read chep ID from 58h by using above two port with the help of Utility like WinIO and Explochip but dont get right result ...

How to read this cheap any has idea ?
