Since the MSI board had the 890 chipset, then you will need to reformat when migrating to the 990 CH5F.
I suggest updating your bios to 0705 prior to reformatting/installing the OS.
Once completed, it's always best to clear the CMOS after a bios update.
if you still get that Intel Lan message, check he bios options for it, but make sure that it is not disabled.
Boot into the OS, then install the latest Intel LAN ProSet driver from Intel's support website.
Do not use the Intel LAN ProSet driver that's on the ASUS CH5F disc or from the ASUS support site.
