Has any body used the K9A Platnum MSI motherboard? its giving me some weird msg's on bootup. first it says of course press <tab> to post and <del> to enter bios. it then gives me another option to hit <shift F10> to configure boot options.. I dont understand that one, and it asks me that twice then goe's to boot and tells me I have no mouse pluged in to the PS/2 port. which I know cause its USB... Can I get rid of that?
