How to Flash a Compaq D500 BIOS

From time to time you may need to upgrade the existing Basic Input Output System installed on your computer. Using an older BIOS prevents newer hardware from interfacing with the operating system, which causes problems if you intend to upgrade components regularly. When an older BIOS causes you problems, HP directly offers the upgrade file to flash the BIOS on your Compaq Evo D500 computer.

Skill level:
Moderately Easy


  1. 1

    Shut down any programs running on the Compaq D500 and bring up the "Start" menu. Click the "Restart" option and wait for the Compaq logo to load on the screen.

  2. 2

    Hit the "F10" key and wait for the BIOS menu to pop up on your screen. If the BIOS menu doesn't load, it means you hit the key too late after the Compaq logo disappears. Restart the computer and repeat the process.

  3. 3

    Highlight the menu option labelled "Main." Scroll down to the entry named "BIOS Revision" to see the BIOS version currently in use. Take note of the version number.

  4. 4

    Press "F10" and hit "Enter." Open your Web browser and navigate to the support page for the Compaq D500 after the operating system restarts.

  5. 5

    Select the "Download Driver and Software" link below the "Tasks for my selected product" heading. Click the "Choose your software/driver language" box and choose your preferred language setting.

  6. 6

    Scroll down and click the link corresponding to the current operating system installed on your Compaq computer. Click the "BIOS" link underneath the "Quick jump to downloads by category" heading.

  7. 7

    Locate the specific BIOS version you want to download and click the "Download" link at the left end of the window. Open the downloaded file and click "Next." Wait for the installation to complete and select "Finish."

Tips and warnings

  • Using the BIOS for the wrong Compaq model, or installing a much older BIOS version, may prevent the Evo D500 from booting up or cause system instability.
