Flashing the BIOS
You may need to flash (update) the BIOS when an update is available or when you replace the system board.

4. Click Drivers & downloads > Find it myself.
5. Select the operating system installed on your computer.
6. Scroll down the page and expand BIOS.
7. Click Download to download the latest version of the BIOS for your computer.
8. After the download is complete, navigate to the folder where you saved the BIOS update file.
9. Double-click the BIOS update file icon and follow the instructions on the screen.
Enhanced Pre-Boot System Assessment (ePSA)
diagnostics
The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded
with the BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular
devices or device groups allowing you to:
● Run tests automatically or in an interactive mode
● Repeat tests
● Display or save test results
● Run thorough tests to introduce additional test options to provide extra information about the failed device(s)
● View status messages that inform you if tests are completed successfully
● View error messages that inform you of problems encountered during testing
CAUTION:
Use the system diagnostics to test only your computer. Using this program with other computers
may cause invalid results or error messages.
NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer
terminal when the diagnostic tests are performed.
For more information, see Dell EPSA Diagnostic 3.0.
