Dell Precision Rack 7910 Owner's Manual

Factory-installed platforms include 32-bit system diagnostics on the installed utility partition. Access these diagnostics using the <F12> keystroke during system boot and select Diagnostics.

After pressing the keystroke, the appropriate modules load and the PSA diagnostics run. If this passes, the standard Dell Diagnostics main menu appears. When exiting the diagnostics, the system reboots and returns to the installed operating system. Restarting the computer with the <Ctrl><Alt><Del> keystroke also returns the system to the normal boot sequence as well.

Drives sent for service replacement do not have the utility partition and therefore do not have this capability. If pressed, the keystroke is ignored on these drives.
