Dell now has a utility to allow for BIOS upgrades in a native 64-bit environment (WinPE).
Begin by downloading the Install File (Flash64W.exe).
- Download the BIOS executable for the specific computer that you are going to update and place it in a directory of your choice.
- Download Flash64W.exe and place it in the same directory as the BIOS executable.
- Open a Windows command prompt (The Command Prompt: What It Is and How to Use It on a Dell System) and go to the directory that you placed the BIOS and the Flash64W.exe file.
Run Flash64W.exe /b=BIOSExecutableName.exe
Note: This is for Client computers only and does not work on Enterprise servers.
