Abstract
An enhanced PCI bus architecture utilizing differential signaling is supported by an adapter slot connector providing differential signaling pins and a make-before-break connection between bus conductors and dummy loads for each bus conductor, enabling higher frequency and higher bandwidth operation. The dummy loads simulate the signal load of an adapter inserted into the slot. The PCI bus conductors are automatically disconnected from the dummy loads and connected to the adapter pins when an adapter is inserted into the slot. A balanced load bus is thus provided regardless of whether adapter slots are populated or empty.
