On the Boot Configuration screen under Configuration>System in Expert mode, an administrative user can redefine the location from which the OnSite boots. By default, the OnSite boots from a boot file in the on-board Flash memory. Booting from the resident software is recommended except when troubleshooting boot problems. The differences between booting from a local copy of the software image and booting from the network are explained in the following sections.
