ABSTRACT:
A computer system including a storage device, a first and second device driver, and a nexus driver. The storage device has multiple bit positions, and is coupled to a set of electrical terminals. A first portion of the electrical terminals is adapted for coupling to a first device, and a second portion of the electrical terminals is adapted for coupling to a second device. Each device driver controls a respective device by generating an access to the storage device, and writing a value to a respective portion of the bit positions. The nexus device driver is coupled between the first and second device drivers and the storage device, and arbitrates between the first and second device drivers for access to the storage device.
