I wish you posted this while you were getting the bluescreens... There is a thread here that explains how to create a full memory dump that we could read and pinpoint the culprit...

The problem I have is that I can’t test it my self on an ASUS board :}, but it should work the same for ASUS as it did for the Gigabyte boards.

I think I have to clear things up a bit; you can’t install the Intel Matrix Storage Manager, as your board doesn’t have RAID. On the net people talk about a modified version that should install, but it’s useless when you don’t have RAID.

Will this procedure work for a Win 2000 Prof SP4 install?

Thanks for your work on XP, puntoMX.

It should work on 2K too, but I didn’t test it. The registry file is the only part that could mess up your machine, so you’ll be doing it on your own risk. You could check if the registry part already exists with different values.

ok, so all of this (very) impressive work is focusing on an ASUS mobo.

What about an Intel mobo with ICH9R??

It’s not motherboard brand related.

For your motherboard you can skip point 2; Preparing the drivers. Your bridge already exists in the driver list.

Please post if it worked ;).

Hi, just got me a new computer and tried to activate AHCI. I'm not sure if it worked.

Motherboard: Asus P5K-V

Hard drive: WD2500KS-00MJB0, 16 MB buffer

Windows XP Pro SP2 64 bits version (yes, I have used Intel Storage Manager 64 bits, too)

CPU: Intel Core 2 Quad Core Q6600

RAM: 2 Gb DDR2 dual channel @ 800 MHz

Everything works fine, no BSOD.

BUT:

- Roadkil's Disk Speed (roadkil.net/DskSpeed.html) gives me the exact same figures as before. The speed is actually lower than my older system (AMD XP 2600+ Athlon, Seagate 250 Gb). The speed has dropped from 65 Mb/sec to 61 Mb/sec, overall score from 8042 to 6789.

- I get ALL these things in the Device manager (see below)

- I have copied stuff from my old hard drive. Top speed: 57 Mb/sec :). But, after going over 20-25 Mb/sec, everyting else just freezes. All other programs almost stop working (tv tuner winfast pvr2, yahoo messenger, notepad, total commander, opera browser). Also, copied from one partition to other, both on this new drive, same thing happens, everything else freezes after 20-30 Mb/sec.

I've got the same poor result before and after activating AHCI.

In the BIOS, I have activated these settings:

- SATA Configuration - Enhanced (before - same Enhanced option was enabled)

- JMicron 3SATA/PATA controller - Enabled (before - same Enhanced option was enabled)

- Controller Mode - AHCI (before it was IDE, other option is RAID)

What could be wrong. Is that hard drive so poor?

Thanks!

@queensoft

The installation did not succeed (by looking at your attachment).

I did exactly like the instructions (I think ;) ).

I think I'll reinstall Windows, 32 bits edition. Is there a huge difference between 32 and 64 bits versions?? I do have all drivers 64 bits, but I use 32 bits applications.

Unless you plan to use 4GB (or more) of RAM, stick to 32-bit.

All right.... reinstalled Windows 32 bit, with IDE mode.

Now, activated in BIOS AHCI mode, but I did NOT do all other things (copy IASTOR.SYS file, add registry....), restart Windows, no BSOD, no errors, everything works fine, the device manager looks like the one above !!!

Soooo, what's going on?!

I would like to help you all out, but the problem is that I only sell Gigabyte motherboards at this time. I also don’t have a 64bit Windows XP to test it on nor do they sell it in Mexico :(.

Soooo, what's going on?!
With the Gigabyte motherboards it loads and installs an AHCI BIOS on boot up before it starts to boot from any data holding media. Does it show any thing like that when you start your ASUS motherboard? I remember that ASUS killed AHCI from some of there BIOSes...

Well, I don't see anything peculiar on boot. The usual fast memory test, drive and dvd rom list, then straight to windows....

I mean, does that motherboard and my Windows both support AHCI? Why do I have so slow hard drive performance ??

Check this out: http://pozze.z1.ro/doc1.htm

The Dskspeed section: first colum (old computer) is FASTER the second column (new computer).

I wonder if your BIOS support real ACHI mode, let me read the users manual of your motherboard now.

Don’t expect much of a performance gain in the benchmarks by the way, I could only test it by starting Windows or other programs and measure the start times with a stopwatch (10 or 20 runs and the average taking from that).

So why the h**l did I bought a nice motherboard like that and a SATA2 hard drive?! :(

Just to work slower than my old one ??

My first choice, however, was NOT this drive, it was a 320 Gb AAKS drive. But, wouldn't you know it, it was just after the holidays and it was out of stock !!

I have a P35 Chipset and this is the procedure that worked for me even though bios doesn't say enhanced only AHCI.

1. Downloaded Newest Intel® Matrix Storage Manager for my board.

2. Command Prompt ran c:\anyfolder\filename.exe /a

3. Copied IaStor.sys from \Program Files\Intel\Intel Matrix Storage Manager\Drivers folder to C:\Windows\System32\drivers\

4. Copied the following registry file into notepad and saved as ahci.reg

5. Double clicked newly created file to install to registry.

6. Reboot and change bios to AHCI

7. Double clicked on previously downloaded Intel® Matrix Storage Manager installer. And Rebooted.

8. Go to device manager, double klick your hard-drive(s) under "disk drivers", go to "policies" tab and mark "Enable write caching for this disk"

I had not installed Chipset Driver yet.
You have to install the driver file first else it will not help.

EDIT: Okay! So it worked after all, congratulations ;).

EDIT2: Could you post your BIOS setting please so I can add them to the first post in this topic.

Thanks, I tried the setup instructions and my AHCI is now enabled. Everything works perfectly. I have a Gigabyte GA-P35-DS3L.

Please see the attachment. The only question I have is how to fix the PCI installation problem using the IAAHCI.INF driver.

Manual Install what?

I assume "IDE/ATAPI controllers",

then "standard dual channel pci ide controller"

Then Browse to IAAHCI.INF and choose it?

Is this correct?

I will post my BIOS settings for you when I get a chance.
