From: Barry Watzman on 9 Nov 2009 22:00 Ok, I have a Gigabyte GA-ex58-UDR3 motherboard, but actually I think that this question is pretty generic and would apply to almost any modern motherboard. I have a SATA hard drive, connected to a SATA port of the Intel ICH10R chipset [actually, I have two SATA hard drives, and two SATA optical drives]. The motherboard has a "Gigabyte" IDE/SATA controller on it (which is actually a JMicron device, which Asus also uses on some motherboards) to provide an IDE port (and additional SATA ports) but since I have no IDE devices, that device is disabled entirely in the BIOS. So it's not part of the question or issue. Here is the question: The BIOS has two settings for the modes of the SATA ports (in the Intel ICH10R): SATA RAID/AHCI Mode (choices are Disabled/Raid/AHCI; set to disabled) SATA Port 0-3 Native Mode (choice are native/legacy, set to native) And the system works fine. But it's using "IDE Emulation" to access the hard drive. So I set the SATA RAID/AHIC Mode to AHCI .... and the system won't boot. It crashes during bootup, which causes a loop of continuous resets. FWIW, I was pretty sure (certain, really) that when I installed this system (Windows XP SP3, by the way), I used an F6 floppy driver to setup the system. So the question: I'd really like the SATA ports operating in AHCI mode. How do I get there WITHOUT doing a total reinstall of Windows? I thought I had the necessary SATA driver installed (via the F6 driver I installed when I first configured the system), but apparently not. So, again: What do I do to convert the system from accessing the SATA hard drives via IDE emulation to accessing then in native SATA AHCI mode, again, without having to reinstall Windows. ???

I think you need the IDE emulation when using optical drives. Is there any reason you don't want to use the IDE emulation? I have another Gigabyte board and it set up and ran perfectly using the default settings. The hard drive hit the max rating in the Vista Performance Rating so I don't think the emulation hurts any.

Enable GigabyteSATA2 interface in bios setup. 2. Boot to XP and install JMicron SATA driver. 3. Move XP drive to GigabyteSATA2 connector. 4. Switch ICH10R mode to AHCI in bios setup, and check Hard Disk Boot Priority that the XP drive is the boot drive. 5. Boot to XP and install Intel AHCI driver. 6.

Where most go wrong (including me) on ICH10R based mobos is to install the wrong ICH10R driver at F6 during the initial XP installation. The one that doesn't work is labelled only ICH10R. The one that does work is further down in the list and (AFAIR) includes ICH8 & 9R in the name. Couldn't even get XP installed in AHCI mode, let alone RAID on a P6T until I discovered this some hours later via a lot of googling. Thanks, for that, Intel.. HTH, -- Rob |
