Afterasystemboardisreplaced,ensurethatthelatestBIOSisloadedtothesystemboardbefore

2.EntertheproductnumberofthecomputerorpressAuto-detectbuttononthescreen.

3.SelectDownloadsanddrivers.

4.Followthedirectionsonthescreenandinstallthenecessarysoftware.

UsethefollowingstrategytopreventunnecessaryexpenseforreplacingandservicingFRUs:

•IfyouareinstructedtoreplaceaFRUbutthereplacementdoesnotcorrecttheproblem,reinstall
theoriginalFRUbeforeyoucontinue.

•Somecomputershavebothaprocessorboardandasystemboard.Ifyouareinstructedtoreplaceeither

reinstallthatboard,andthenreplacetheotherone.

•IfanadapteroradeviceconsistsofmorethanoneFRU,anyoftheFRUsmaybethecauseoftheerror.
