I built a machine March this year with a Gigabyte X58A-UDR3 (rev1) mobo holding an i7-920. 6Gigs 1066 Crucial memory. Nothing unusual there, not overclocking at this time. Bought two Barracuda XTs for data as they were SATA-III and there are two SATA-III connectors on the mobo. Because I am re-installing Win7-64 now to start fresh and inserting a new SSD as a boot drive -- I have two or three questions scattered around Tom's Hardware in relevant forums.
This is one of them:
Why won't the HDs show a BIOS-chosen switch to AHCI during boot?
One of the reasons for the re-install is to get all drives on AHCI-based I/O. The BIOS has several places where you make this election. Each chipset involved gets its own choice of IDE/AHCI/RAID. The bridge handles 6 of the connectors, Marvell handles two, and another operates the last two. Seems each has a place in the BIOS. Makes sense, I guess. I re-read the documentation carefully and made sure I visited each choice, setting these for AHCI. The boot screen go by really quickly so I photographed them for later reading and information for Gigabyte. The two XTs show as IDE during the first screen. When the AHCI device page comes on there are three devices listed: another HD (a WD Velicoraptor that is meant to be the boot drive but not working -- that's another thread...) and my two optical drives. Then my external eSATA drive shows up on its own boot screen. (Cool!) All these used to be listed as different channels in IDE when I booted before, so some devices made the switch and the two XTs did not.
Unfortunately, it will take a while for Gigabyte to get back to me (sometimes days) so I am reaching out to you guys for another viewpoint. ...and I suppose I should also call Seagate and ask them about their take.
One odd thing shows in my Device Manager. The Marvell driver shows that it is "Not installed". I believe Win7 used to install these drivers as a second step in booting, and I never understood why. You see, right now because of a BOOTMGR is missing" error on the Velicoraptor I have to run Win7 from the OEM DVD. This is the controller these two XTs are connected to. Perhaps I will switch their cables to a SATA-II port and see if they show up as switched to AHCI.
OK, long post. Stop now. Thoughts?
