It *probably* means that the motherboard has what's known as a 
'fake-RAID' device (and at least two HDD) and that was using a special 
driver in f13, which has to be specified at the install.

If the system is installed without the driver it won't work right at all.

Do you need RAID?

If not, then you can turn it off.

That will destroy access to anything on the disks, but it will then act 
as a normal disk controller and the install should work OK.

Check in the BIOS for the configuration of the hardware.

You may find that the hard disk controller is offered as a config option 
when you boot up (alternatively it may be an option in the main BIOS).

There will be another option offered: AHCI, probably.

Disable anything to do with RAID and set the disks to normal (or AHCI) 
mode and reboot, retry the install.

If that does not work then there may indeed be (as suggested) a 
motherboard hardware fault...

Sorry I can't be any more specific, the specifics will be in the manual 
for the motherboard/unit which you could find and download and consult.
