Their should be ( on the site where you found the update) information as to what issues it specifically addresses.Most of the time it is advisable to update chipset
drivers. They control all the way everything your MB does, from the Ethernet to NB to Sb and ram communication. Where as a bios update should only be done if it specifically addresses issues you are experiencing, or new support for your CPU. This is of course my opinion. There'll be others I'm sure.Fabe
