Updating the BIOS and BMC on MK400-60

Preparing the flash drive.

A small (16GB or less) flash drive is required for this process.

Begin by installing DOS to the flash drive per this tutorial.

Download this zip file and extract the contents directly onto the flash drive. Several files will be overwritten. This is ok.

Performing the update

  • Begin by removing any graphics cards from the system. It is safest to remove all other PCIe cards as well.
  • Connect VGA to the system. It is required to use VGA during the BMC update.
  • Plug the flash drive you created in the previous steps.
  • Power on the server. With the graphics card removed it may take an extra few minutes to switch over to VGA and output a video signal.
  • Once you see the splash screen, press the Del key a few times to access the BIOS.
  • Navigate to the Boot tab and set “Boot Option #1” to your flash drive.
  • Press F10 to Save & Exit.
  • The server will reboot and after a few minutes you should see the DOS screen with the update prompt.
  • Press Y and then Enter to begin the BMC update.
  • The update will take approximately 5 minutes.
  • The server will automatically reboot when the update is complete.
  • After the server reboots, it will go back to the DOS prompt. Unplug the flash drive and press control-alt-del to reboot.
  • It is safe to do this as long as you have not yet pressed Y and Enter.
  • Go back into the BIOS with the Del key.
  • Navigate to the Advanced tab and choose Instant Flash
  • Press enter to begin the BIOS update.
  • When the update has completed, the system will say “press any key to reboot”
  • Unplug the flash drive and press any key.
  • The update process is now complete.
  • Unplug the system and reinstall any cards you removed for the update.
  • On the next boot, the system may take an extra few minutes to switch back to the graphics card.
