An electronic disk swapping system for a wireless network application processor (AP) includes two or more hard disks connected to the AP by a SCSI bus. A disk selection unit (DSU) is connected to the hard disks and to a user interface. In operation, a user accesses the user interface to select one of the disks from which the AP will boot upon start-up. Based on this selection, a control code is generated and sent to the DSU. Based on the control code, the DSU generates a primary identifier (ID), which is applied to the selected hard disk. The "primary" ID is an identifier that the AP and/or bus associates with a source from which to automatically obtain software upon start-up of the AP. Subsequently, upon start-up, the AP determines which of the disks assigned the primary ID, and boots from that disk.
