Thanks
No need to check BIOS, try to probe I2C device on that address instead. If there is some valid I2C device - you have at least a chance. But that's just a chance, the reality devends of the PX3544 programmability level (it can allow both I2C voltage override and monitoring as well as a single monitoring only).
