The following files are latest versions of the D845WN and D845HV BIOS. Check your current BIOS version during the boot cycle or during BIOS setup and compare this with the posted BIOS version.
While both files include the same version of the BIOS, these files differ in the way the user installs the BIOS. The first "BIOS Update" file is in the traditional format that requires a boot disk and the BIOS is flashed during the boot cycle. The "Express BIOS Update" is the same BIOS version but it can be ran as an executable file while the system is fully booted and fully running. The Express BIOS Update offers ease of use, and it is an alternative to the traditional boot disk method.
