Multiple security enhancements and Intel® Manageability Engine (Intel® ME) updates can change the BIOS update process for Intel® Desktop Boards DQ965CO, DQ965GF, and DQ965WC.
- Intel® Express BIOS update
- iFlash BIOS update
- BIOS recovery
- Clearing the CMOS
- Reverting a BIOS to a previous release
- BIOS update errors
Intel® Express BIOS update
Intel Express BIOS update allows a BIOS update to be initiated from a Windows* environment.
Systems that have Intel® Active Management Technology (Intel® AMT) provisioned1 must also use other information to meet the enhanced security that prevents unauthorized BIOS updates. To update the BIOS on a system with Intel AMT provisioned, use the following command line with the added switches to launch the Express BIOS update utility:
CO96510J.86A.xxxx.EB.EXE -s -a force user admin pass password -s
- xxxx = BIOS revision number
- admin = Intel ME login name
- password = Intel ME password
For general instructions on using Express BIOS update, see Instructions for Express BIOS Update.
IFlash BIOS update
IFlash is a DOS-based utility to update the BIOS regardless of operating system. Because of enhanced security, IFlash cannot be used to update the BIOS on a system that has Intel AMT provisioned1.
BIOS Recovery can be used when other BIOS update methods have failed. BIOS Recovery unprovisions Intel AMT and can reset BIOS and Intel ME values back to their default settings.
For general information on the BIOS recovery process, see Instructions for Recovery BIOS Update.
Clearing the CMOS
In the event that the BIOS update process fails, you should clear the CMOS to restore the system to a functioning state.
- Remove the CMOS battery
- Turn off all peripheral devices connected to the computer.
- Disconnect the computer power cord from the AC power source (wall outlet or power adapter).
- Remove the computer cover.
- Find the battery on the board.
- With a medium flat-bladed screwdriver, gently pry the battery free from its connector. Notice the orientation of the " " and "-" on the battery.
- Wait five minutes and then replace the battery.
- Set the onboard configuration jumper to Configuration (Maintenance) mode. See the board specification for the location of this jumper.
- Reconnect all peripheral devices and AC power.
- Boot up the system. The Maintenance BIOS setup menu automatically loads.
- Reset Intel ME to factory defaults.
- Return the onboard configuration jumper back to Normal mode.
Reverting a BIOS to a previous release
Intel suggests using the latest BIOS available. Sometimes, it can be required to revert to a previous version of the BIOS for troubleshooting or test reasons. Not all boards can be reverted to earlier versions of the BIOS.
BIOS update errors
Intel Express BIOS update and iFlash both fail with the error message:
(iFlash update failed)
This failure occurs when trying to revert from a BIOS version CO96510J.86A.5595 or earlier to BIOS version CO96510J.86A.5493 or earlier. BIOS recovery to the earlier version should be tried.
1 Provisioning is the process of configuring Intel AMT and Intel ME parameters in BIOS so the technologies can be used.
