ROM issues
System requests recovery method during a firmware update
Symptom
The system requests a recovery method during a firmware update.
Action
1. When updating the firmware on a BitLocker-encrypted server, do the following:
a. Always disable BitLocker before updating the firmware.
If BitLocker is not disabled, the system requests the recovery method selected when BitLocker was
configured. Failure to provide the correct recovery password(s) results in loss of access to all encrypted
data.
b. Update the firmware.
If BitLocker is configured to measure option ROMs, follow the firmware upgrade steps in Keeping the
system current.
BitLocker can be configured to measure the following option ROMs:
• NIC
• Smart Array storage controller
c. After the firmware updates are complete, enable BitLocker.
For more information on BitLocker, see BitLocker for servers on the Microsoft website.
Updating firmware
Procedure
1. Check the firmware version on the device.
2. Determine the latest firmware version available.
3. If a Trusted Platform Module (TPM) is installed and enabled on the server, disable BitLocker before
updating the firmware.
For more information, see the operating system documentation.
4. Download and update the firmware to the current version supported for the hardware configuration.
5. Verify the firmware update by checking the firmware version.
6. If a TPM is installed and enabled on the server, enable BitLocker after the firmware update is complete.
For more information, see the operating system documentation.
