ZIP archive of 8.24 MB labelled BIOS update with the number 1970, which may be a version or build identifier, though the name does not say which device or manufacturer it targets. Such packages usually contain a vendor flashing utility and a BIOS image intended to be run from Windows or a bootable USB. Before using it, identify the exact model the update belongs to, read the included notes, keep the system on stable power and save a backup of the current BIOS chip contents if a programmer is available.
