atacontrol doesn't exist on 4.5-RELEASE but he can use
sysctl.ata_modes which should be "dma,---,pio,---" or
something like it.  sysctl ata.ata_dma should be 1.

I will also second your recommendation to check all the
relevant hardware carefully in spite of what the BIOS says.

If all else fails, he should post dmesg output and may be that will
joggle someone's memory!
