This board - and its BIOS releases - are so old that the Express BIOS Update (EBU) packages are likely not compatible with the latest O/Ss. Further, I do not believe that these BIOSs had support for the F7 update method. You are going to have to download the package that provides the BIO file for the latest BIOS release. Place this file onto a FAT (or FAT32) formatted flash drive, plug this drive into one of the board's back panel USB ports, remove the BIOS jumper and power on the system. This should install this BIOS using the recovery method. The alternative is to build a DOS-bootable flash drive, place the BIO file and the iFlash utility's executable on it, boot from this drive and run the iFlash utility to install the BIOS.
Hope this helps...
The current BIOS version is old now, there are almost 14 newer BIOS versions. Update the BIOS to the next available version 3869. Bear in mind, Intel® recommends to update the BIOS if system is experiencing issues.
