Notes: this function may require up to 1024 byte of stack; it will not enable
     interrupts if they were disabled before making the call
   device ID FFFFh may be reserved as a wildcard in future implementations
   the meanings of BL and BH on return may be exchanged in future
     implementations
   all devices sharing a single vendor ID and device ID may be enumerated
     by incrementing SI from 0 until error 86h is returned
