BIOS Silent Flash

This script will perform an unattended flash of the BIOS.  It will only push header (.HDR) files to the system's CMOS for the BIOS upgrade. The .HDR file will need to be extracted from BIOS upgrades. New Computer models will need to be added to the GetComputerModel() procedure, and old models removed. When adding new computers, the relative path must be placed in front of the .HDR filename. This script was written for Dell systems, but can be modified for other brands.

NOTE: Instead of using this script for dell machines, I soon learned of the hidden switches and blogged them here for all of their BIOS upgrade files. This script can still be used though for flashing the BIOS. It will have to be modified if you would like to use this script for other model machines. You will need to change the GetComputerModel procedure for the different models/brand machines.

You can download this script from here.
