The latest system BIOS (standard flash operation) can be downloaded from

Instructions on updating the BIOS are supplied with the downloaded BIOS
files and a BIOS flash utility (phlash.exe).
The BIOS update not only flashes the BIOS, but also updates hardware
monitoring firmware. How the System BIOS flash is carried out is shown
below.
Do not switch off the computer until the system BIOS update procedure has
