No guarantees, though it designates an Optiplex 7040, it's the only article that I ran across that didn't just say to update or recover BIOS. I don't know if you saw it already. I don't know which jumper connector on MB is for Service Mode (if it has one). Hopefully it says on the MB.
Use only USB 2.0 flash sticks. Do not use USB 3.0 flash sticks! Reformat this flash stick using the FAT32 file system. Do it even it the flash stick was already formatted. Do it on another Windows PC; do not use Linux. You do not need to make it bootable. The BIO file (JO1143P.BIO) should be the only file that you put on the flash stick. While following the documented process, plug this flash stick into one of the (black) USB 2.0 ports on the back panel of the board. Do not use front panel PC ports.
