Overriding this failure to install the BIOS
Updating the BIOS from version 03.01.0038 to version 03.01.2032 in an Intel® Server Board S1200SPLR fails, saying that the capsule file is invalid. It has been downloaded and copied several times into a USB flash driver to install it via the EFI shell, but the error occurs every time.
Move the BIOS Recovery jumper to Recover position, and install the BIOS while the jumper is in this position. After the update is successful, move the jumper back to the Default position.
Instructions on how to do a BIOS Recovery Procedure are found in the BIOS Recovery Procedure for Current Intel® Server Boards article.
