Abstract
A universal bus communicates information by one of plural bus protocols. A bus protocol selector is operable to select one of the plural bus protocols associated with a device interfaced with an information handling system and to communicate information over the bus with the selected bus protocol. An Input/Output chip includes a protocol selector unit that selects a bus protocol I/O unit to communicate with the device over the universal bus. The bus protocol I/O unit communicates over the universal bus by using a bus protocol that is compatible with the device. For instance, the one of plural available differential serial bus protocols is selected so that the bus protocol I/O unit communicates with the device using a bus protocol compatible with the device. In some instances, a bypass circuit configures the physical characteristics of the universal bus, such as by interfacing or removing a capacitor with the universal bus to support AC or DC coupled bus protocols.
