WARNING

Do not upgrade the BIOS unless your system has a BIOS-related issue. Flashing the wrong

BIOS can cause irreparable damage to the system. In no event shall Bull be liable for direct,

indirect, special, incidental, or consequential damages arising from a BIOS update. If you

have to update the BIOS, do not shut down or reset the system while the BIOS is updating.

This is to avoid possible boot failure.
