Documentation

This is a slight modification of the Dell BIOS Flash file. You simply need to send the HDR file down to the computer and it will install and restart there is no warning. There is no way to stop the restart. It is recommended that you push this down with either user interation with a warning or while no user is logged on. Download the BIOS update (i.e. GX755.exe) use GX755.exe -writehdrfile to extrac the GX755.HDR file from the exe. Send down the adv with the following command line: cscript.exe //nologo Flash.vbs header.hdr I will note that there was a different method to flash the BIOS. This method has been tested on at least the GX620 Optiplex line and above.
