Dell Command | Configure Version 3.0 Command Line Interface Reference Guide

Enables or disables Force PXE on next boot in BIOS.

If enabled, when the BIOS boots next time, the first PXE-capable device is inserted as the first device in the boot sequence. Enabling this value causes this operation on the next boot only, and does not cause a change in the defined boot sequence of the system. The BIOS chooses the first PXE-capable device as the onboard network controller of the system, if present and enabled, or the first bootable network device found in the standard PCI search order of the system- whichever comes first.

If disabled, the boot override feature is disabled and the system boot sequence is in effect.
