Key Combinations

<Ctrl><Alt><Del> If running Microsoft® Windows® XP, brings up the Windows Security window. If in MS-DOS® mode, restarts (reboots) the computer
<F2> or <Ctrl><Alt><Enter> starts embedded system setup (during start-up only)
<Ctrl><Alt><b> automatically starts the computer from the network environment specified by the remote boot environment (PXE) rather than from one of the devices in the system setup Boot Sequence option (during start-up only)
<F12> or <Ctrl><Alt><F8> displays a boot device menu that allows the user to enter a device for a single boot (during start-up only) as well as options to run hard-drive and system diagnostics
