I'm attaching the drivers I used to initially force the AHCI drivers on the controller in XP in case anyone else was having trouble finding them.
Now just need to setup PowerDVD for HD-DVDs and BluRays...

Well I finally got around to figuring this out and here is how to do it.
The following will enable you to use all 6 SATA ports on the Mac Pro Early 2008
It might enable AHCI on other Mac platforms, however I have none to test with.
There was mention of a MacBook Pro user enabling AHCI for faster drive access in Windows on the OnMac forum.
This will let you add your Blu Ray or DVD SATA drives to your Windows install without losing one of your hard drive bay Sata ports.
This will increase your data transfer speeds in Windows from the 100mb speed of the legacy mode to the native 1.5gbps or 3.0gbps of your SATA drive.
I give credit to pipomolo42 for figuring out that it can be done.
And for the Modified Stage1 file for the GRUB boot loader.
It was done on the OnMac Forums in the middle of 2007 in an attempt to enable RAID 5 in Windows.
However it wasn't easy for the casual user or power user to get done with out having major headaches.
Here are the links to the required files that will be needed.
Download and install rEFIt from inside OS X
Windows XP/Vista x86/x64 Intel Matrix Storage Manager Drivers - Direct from Intel Website
Ubuntu Live 8.04.1 AMD64/EM64T Desktop Version - Download from your nearest location, make sure to choose the desktop version for the 64 bit based systems, this is a CD based version and will therefore fit on a CD-R.
The attachment "boot.zip" contains the Modified Stage1, Stage2 and Menu.lst that are needed for the GRUB installation to work properly on the Mac Pro.
There are several methods that you can use to setup your system.
I will go through Vista and XP for those that are already installed.
It is possible to install fresh versions of the OS by loading the install disc
through grub and providing the drivers for the AHCI controller via USB
for Vista or slipstreamed in XP or Vista.
1. Load Live CD
- Run Partition Editor
- Create a small FAT32 Partition at the beginning of the drive
- I chose to make a 100mb partition and formatted it to FAT32
- This re-sized and moved my XP partition down the drive by 100mb - this took about 45 mins
2a. Reboot into XP (if using Vista skip this step and use step 2b)
- Force the installation of the AHCI mode driver over the Legacy driver
- Open device manager
- Under IDE / ATA section open properties for the "Intel® 631xESB/6321ESB Ultra ATA Storage Controller - 2680"
- Update the driver for 2680 with one labeled 2681 (ESB2 SATA AHCI Controller)
- You will need to uncheck the box that limits you to only known supported drivers for your hardware
- Once installed it will require a restart
- Attempting to restart into XP after this will leave you with a BSOD and instant reboot, this is caused because XP is loading the AHCI driver and it is failing to load because the hardware is still in legacy mode.
2b. Vista only
- Run Regedit
- Navigate to "HKLM\System\CurrentControlSet\Services\msahci"
- edit the "Start" key and change the value from what it is to "0"
- this will tell Vista to check for AHCI on next boot and install the AHCI driver if it is in AHCI mode
3. Load the Live CD again
- Copy the provided stage1, stage2, menu.lst to the following location on the 100mb partition
- Time to install GRUB bootloader
4. Open Terminal - enter following commandssudo grub --device-map=/dev/null- This will tell GRUB to ignore the built in device map of grub and that you will define a new one.device (hd0) /dev/sda- This maps your first hard drive as the device "hd0" in grub - keep in mind that GRUB counts up from 0
- grub will echo the command to confirm it was accepted.find /boot/grub/stage1- This will echo the location of the stage1 file - ex: (hd0,2)
-This would translate to hard disk 1 partition 3 for normal people
- You will use the (hdX,Y) for the next steproot (hd0,2)- This tells grub where to obtain the stage1, stage2, menu.lst files fromsetup (hd0)- installs grub bootloader to MBR of first hard drive in system
- it will echo if the installation has succeeded or had errorsquit- to quit grubexit- to close terminal
5. Restart and remove Live CD
6. From rEFIt Menu choose boot Linux from HD (the Penguin icon)
7. It will load Grub then show a boot menu for
- Windows XP in AHCI Mode
- Windows Vista in AHCI Mode
8. Take it from there and enjoy having 6 Sata ports that have the proper performance with NCQ enabled
You may need to edit the "menu.lst" file for the appropriate locations of the operating systems on your machine.
On my system I am using an IDE drive for my XP install and that is also where grub is installed to.
I have 4 hard drives installed 1 IDE, 3 SATA.
I have 1 OS installed on each of their own physical drive.
On your system you might not be using /dev/sda because that is most likely going to be your Mac OSX drive
Chances are you will use /dev/sdb for the second sata bay in your case.
Swapped this post to beginning with the 4th post to have the HOWTO be the beginning for the topic.
For some reason this topic will not notify me via email about replies so if I don't respond to questions right away that is most likely the reason.
I do however check back often.
I'm SO confused, sorry, I'm completely new at command-line stuff on Windows. What is Live CD and how do I load it? I'm trying to boot Vista-32 with AHCI on an Early 2008 Mac Pro with Boot Camp so that my SATA port-connected LG GGW-H20L Internal blu-ray drive will show up in Vista, and I can't seem to understand you're directions because I'm kinda stupid at this stuff! Is Live CD something that came with Vista installation kit, because if so, I'll need a burned copy because I no longer have any disks.
Working very nicely for me, thanks
What I'm thinking about now is a way of simplifying the method
so that less technically inclined people can take advantage of it.
(1) Can be done entirely within Windows
(2) Does not require a linux CD/DVD
(3) Uses as few external tools as possible
(4) Is simple enough to be done very quickly
first of all, sorry for my English, I'm Italian, so please be patient.
I'm trying to follow "ludacrisvp" tip by creating the grub partition but, I'm having trouble on third step "find /boot/grub/stage1", grub is returning this error "Error 15 no file found". Could you please help?.
My config is :
Mac Pro Early 2008 2 Xeon 2.8 Ghz & 10GB Ram, nvidia 8800GT
Bay 1 - 1TB for Time Machine
Bay 2 & 3 Raid 0 for my primary OSX & Data
Bay 4 (3 partitions) OSX (for testing), Vista Ultimate 64 bit and Windows
P.S. I'm new to the Linux staff
BTW, I'm using Ubuntu 8.10 64Bit
Thanks in advance
I'm having trouble on third step "find /boot/grub/stage1", grub is returning this error "Error 15 no file found". Could you please help?.
I cant get it to work. I have a 35 mb partition with the folder /boot/grub -- all the files are in there.. like the stage1
Make sure you have the latest Intel AHCI drivers installed (you should see a piece of software called "Intel Matrix Storage Manager" installed with those drivers) because the included with Vista ones really are horrible.
Ok so after I got all excited that it now works and I can watch blurays on my mac, I booted back into OS X and tried to start my Windows partition via VMware only to find this no longer works now. It boots into the grub bootloader but just says "GRUB " in the top left and freezes. Anyone know if it's possible to be able to use a Windows partition setup with grub for AHCI in VMware also? I don't need VMware to load the gurb bootloader in this case since it already uses AHCI, but it insists on booting into the grub partition.
