A 2.00 MB dump for the Dell Latitude E6520, labelled rom nguon, Vietnamese for power ROM, which indicates the power-management or EC-related chip rather than the main BIOS. On this platform the main BIOS sits on a separate, larger chip. Use it to address no-power or power-sequencing faults linked to corrupted firmware.
