    Exclamation AHCI BIOS error 23 after enabling AHCI from IDE mode

    Gigabyte GA-EP45-UD3P, rev1.6
    BIOS FE.

    I was trying to do a clean install of Windows 7 over the top of an existing Win7 install. Before starting the install, I switched the SATA controller to AHCI mode in the BIOS, but it wouldn't boot past the AHCI BIOS Screen, showing the following error:
    Serial ATA AHCI Bios, Version iSRC 1.20E
    Copyright (c) 2003-2008 Intel Corporation_________________________23
    ** This version supports only HardDisks & CDROM drives **
    Please wait. This will take a few seconds.

    Controller Bus#00, Device #1F, Function #02: 06 Ports, 04 Devices

    If I set the SATA controller to IDE mode in the BIOS I can then install Win7, but when I set the SATA controller back to AHCI mode, (after changing the registry keys for the AHCI driver in Win7) a reboot gives the same AHCI error:
    Serial ATA AHCI Bios, Version iSRC 1.20E
    Copyright (c) 2003-2008 Intel Corporation_________________________23
    ** This version supports only HardDisks & CDROM drives **
    Please wait. This will take a few seconds.

    Controller Bus#00, Device #1F, Function #02: 06 Ports, 04 Devices


    I have seen this same error posted on many other forums as well as Tweaktown, but haven't seen the resolution explained. Of most interest is sstalhman's post, but it doesn't quite explain how to fix it clearly enough that I can do it without being concerned about breaking everything.

    I assume I need to:
    • Use dskprobe or hxd to edit the partition table - how exactly?
    • Write down bytes 0x1C3 and 0x1C4 (they'll be 0xFE and 0xFF with one partition, something smaller on a dual partition setup; doesn't matter, they're not used for anything important other than crashing your BIOS) - are these the correct values that I'm looking for when I'm trying to FIX the problem?
    • Change these to something small: 0x06 and 0x05 will work nicely (giving you 7, 6, 5) - what should I change the values to when trying to FIX the problem?
    • Save and reboot in AHCI mode
    How do I go about fixing this please?


    PS. When are Gigabyte going to fix this problem???

    did you do this? this is the way i enabled ahci in win7 after installing in ide mode

    boot up into ide mode and make the changes

    1. Startup "Regedit
    2. Open HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlset / Services
    3. Open msahci
    4. In the right field left click on "start" and go to Modify
    5. In the value Data field enter "0" and click "ok"
    6. exit "Regedit"
    7. Reboot Rig and enter BIOS (hold "Delete" key while Booting

    In your BIOS select "Integrated Peripherals" and OnChip PATA/SATA Devices. Now change SATA Mode to AHCI from IDE.

    You now boot into windows 7, the OS will recognize AHCI and install the devices.

    what exact mother board do you have? Along with what bios is installed?

    Have you tried to set the controller to raid? Raid uses ahci also but maybe it will pass. You can leave set to raid with a stand alone disk.

    Thanks wazza300, yes that was the method I followed as I linked to the MS KB article.
    Anyway, this is a BIOS problem, NOT an OS problem. If I hadn't completed those steps in the OS, I would have either a BSOD or a boot loop.
    During boot the OS doesn't even start loading as it hangs on the AHCI BIOS as per the error.

    Sorry, my bad, it's a Gigabyte GA-EP45-UD3P, rev1.6
    BIOS FE.
    No I haven't set it to RAID. I'm pretty sure the RAID BIOS is slower to boot than the AHCI and it's running as a HTPC so it's needs as quick a boot time as possible.

    Regardless, this is a fault with the BIOS that I need to be able to fix. There are heaps of posts from people with the same problem, but no instructions to fix it with the hex editor.
    Google - ahci isrc error 23
    Google - bios ahci hang error 23

    Further to this, after setting the SATA Controller to AHCI mode in the BIOS and trying to boot the OS, because the AHCI BIOS hangs, there is no way to re-enter the BIOS and change it back to IDE. You need to either disconnect the hard drives or clear the CMOS back to default. This happens because it goes through the POST checks including the AHCI BIOS before entering the BIOS configuration screen. Total pain in the ass!

    I just tried RAID mode on the SATA controller and get the same error on the SATA AHCI BIOS screen:

    There weren't any problems with AHCI enabled before I did a "custom" install on my P35-DS3L system.
    RST could not be installed because the ICH9 chipset is not supported.
    I hope this helps.

    Is your drive in SATA port 0?
    I was getting freezing on 23 (and other numbers) with an SSD in port 0 on my Z68X. Moving to port 1 stopped the problem occurring.

    There weren't any problems with AHCI enabled before I did a "custom" install on my P35-DS3L system.
    The cause of this problem is the partitions on the disk and the way the AHCI BIOS reads the partition information. I noticed you created 5 partitions on your disk; I think this resolved the problem before it even started.

    Interesting. Yes, my boot disk is on SATA port 0.

    POSSIBLE RESOLUTION:
    I have actually found a simple fix for the problem.
    I shrunk the Windows 7 System Reserved partition by 1MB to modify the partition information on the drive (I couldn't figure out how to do it with the hex editor).

    Open Computer Management, then go to Disk Management, select the 100MB System Reserved partition on the boot drive and right click and select Shrink Volume. then shrink the volume by just 1MB.

    I'd still like an actual solution to this (I've only applied a band aid fix).
    Even more, I'd like Gigabyte (and other vendors) to fix the problem with the BIOS to prevent this from happening in the first place.

    Same thing, Just equal happens to me with an X48T-DQ6 when i first install an SSD Patriot in IDE mode. I have never find a solution, and Im still using this SSD in IDE for that reason. About your Fix, I check my Disk C and I c,ant see any partition there for shrink. Do not exist in my case, Why? I d,ont know

    Hi ea3ot,
    You could try to shrink the volume of your C: drive by 1MB and see if that works, but I don't think it will.

    Otherwise, if you have only recently installed Windows 7 on you Patriot SSD, then I would suggest reinstalling Windows on the SSD to create the correct partitions (including the System Reserved Recovery partition). Backup any data first then reinstall Windows. During the Windows installation process delete any partitions that exist on your Patriot SSD, then select the Patriot SSD as your installation location; do not create any partitions first.
    The Windows installation process should create a 100MB System Reserved partition which you can later resize.
    Windows will also automatically align the partitions on the SSD for optimum performance.

    Please let us know how you go as there are a LOT of people out there that have this problem. But unfortunately, I haven't found any other answers.
