hi all. i just got an asus a8r32 mvp deluxe crossfire board, and it has tons of options in the bios im not used to seeing. one of them, under storage, allows you to run your sata drives in 'emulated pata mode' or 'AHCI mode.' i have read that AHCI is faster, but what exactly does it do, and how do I get my computer to support it, because everytime I enable it my system reboots and will not load windows. thanks.

hi everyone, i'm new in this post, i'm nicfalc and i have some problems with my laptop, a toshiba satellite pro l40.
the problem is that i bought a new ssd but everytime that i boot the pc i got an error of s.m.a.r.t. command failed.

so i did some research on the net and i found that maybe it could be the fact that the mobo is set in ide mode and not in ahci mode.

i can't find the section in the bios to change it,and maybe this mobo isn't capable of doing that.

what can i do to change in ahci mode without trying to flash a new bios ect....

i'm currently on windows 10 pro 64 bit.

Hi.

XP and Seven are installed in dual-boot on my laptop, and I use EasyBCD to choose which system I want to start.

To start XP, I need to enable "Compatiblity" (SATA controller mode in the BIOS) and for Seven is "AHCI" to be activated.

Is there a way for my two OS been booted without making changes in the bios?
Is there an update to fix this problem (or an alternative)?

Thank you in advance.

A:Satellite Pro L300 - Dual boot with AHCI mode

Yes you can do this but I?m afraid you must reinstall WXP.
Why? Because before WXP installation start you must change to AHCI mode, start WXP installation and before you start it you must load SATA driver (using F6 I think).

Long time ago we have discusses a lot about this on this forum so use advanced search options anc check other postings about this.

Now when I enter the bios setup during boot it defaults to non-supervisor mode and I can find no way to get it to prompt me for the password to allow me to make changes.

A:Satellite NB10 - enable BIOS supervisor mode?

> Now when I enter the bios setup during boot it defaults to non-supervisor mode and I can find no way to get it to prompt me for the password to allow me to make changes.

Usually if the supervisor password has been set, you can access the BIOS pressing F2 button.
Now you have to insert the Supervisor Password or you can proceeds with limit access to different BIOS options by pressing the F11 button.

If you have inserted the right supervisor password, you could delete it again in the BIOS security tab.
Usually you have to insert the right supervisor password and have to press ENTER twice just to delete it. Then save the changes

Here an short description what the supervisor password does.

Hi, I am using a HP Pavillion 180t computer with Window 7(SP-1), IE9 RC. 12GB Ram, Quad Core i7, 3.33Ghz.

I do not have AHCI enabled based upon the Tutorial to do so. Would enableing AHCI be of value to me? If so how? Any help appreciated.

A:AHCI to Enable or Not?

You get some more advanced features with AHCI like hot plugging and better native command queuing. It will improve performance especially on benchmarks. Real world performance is a lot less noticeable.

I used to run my rig on IDE, because AHCI introduced an 8 second delay at boot which I never felt I earned back in performance. On a later BIOS update, that 8 seconds went to 2, and I switched to AHCI at that point. It's going to really depend a lot on you and your exact machine.

hi...
i found several tutorials to enable the AHCI-driver in win7/vista but the registry keys don't match mine...

the tutorial is as following:
1. Exit all Windows-based programs. 2. Click Start, type regedit in the Start Search box, and then press ENTER. 3. If you receive the User Account Control dialog box, click Continue. 4. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
5. In the right pane, right-click Start in the Name column, and then click Modify. 6. In the Value data box, type 0, and then click OK. 7. On the File menu, click Exit to close Registry Editor


but in my registry key the key "Start" does not exist and the Msahci is called msahci (though i don't think the capital letter makes a difference).
it has a "Default" value which doesn't enable the driver if set to 0 (instead of undefined (or something similar)

should i just create a value named "Start" and set it to 0 ?

thanks for helping

AFAICT, you cannot change it - it needs to be set when installing. Then you'll have the correct key there, and will need to simply enable it by changing the value.

if the key is not there and you add it, it may cause your system to hang / reboot constantly / all sorts of other problems.

Hi,

I have a Dell Studio 1555 laptop. I installed XP SP3 fresh from scratch, and I had to set AHCI to IDE in the BIOS in order for the install to complete. I finished the XP install and installed Dell drivers for video, wireless & LAN. When I go into BIOS again and re-enable AHCI, Windows does not boot up. I get a few lines that flash on the screen that I can't read and it reboots. If I turn AHCI back to IDE it boots up normally. How can I get AHCI turned back on after having installed XP?

Thanks
 

A:Cannot re-enable AHCI after install of XP SP3

You cant if you want to stay with xp. to run windows xp correctly it has to be in the IDE mode. in most cases AHCI is used only for the vista and windows 7 operating systems. if you try to change it back and run xp it will blue screen on you or wont boot at all.unless a computers BIOS only has one setting and theres no other choices listed then and only then can you use the AHCI mode to run xp, vista or windows 7 equally well with no glitches.

I hope I am not duplicating something here. . . . I did look - Honest!

I ran into an interesting problem and found an easy fix.

First: I wanted to ENABLE AHCI because (supposedly) it improves HDD performance. (It also enables a host of other interesting features.)

I discovered the trick of setting the START paramater in the registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci
from "3" to "0" - and then making the switch in the BIOS.

I tried to switch back, and simply resetting this start value to "3" doesn't work.

The issue here is that there are actually TWO keys that control the IDE/AHCI interface choice:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\pciide
When the system is in IDE interface mode, the respective start values are:msahci's START value is "3"
pciide's START value is "0"
When the system is in AHCI interface mode, the respective start values are:msahci's START value is "0"
pciide's START value is "3"
It is entirely possible that setting the START value to zero in the key representing the interface type you wish to use, may cause the corresponding key in the other interface type to automagically switch to "3". I do not know this, nor have I tested it.

What works for me is setting both START values to the values that correspond to the interface I wish to use.

It should be trivially... Read more

Hi jharris. Welcome.

For me, the reasons to enable AHCI are Native Command Queuing and Hot Swapping, hot swapping being the most important to me.

As far as switching back and forth, I could imagine issues arising from that (including confusion as to what mode I was running in at a given time...).

But if I needed to do it as a utility to convert drives to vhd's, I would consider a dual boot, with the AHCI disabled boot just a simple OS with whatever utilities I needed to get the job done. Keeping it simple would mean a quick boot to desktop and a small partition.

Okay I plan on doing a clean install of Windows 7 on my laptop. I have an SSD from crucial.

I know that I need to enable AHCI BEFORE I start the installation of Windows 7...correct?

Now....I saw this Intel website in regards to AHCI.
Intel? Rapid Storage Technology — Configure the BIOS for RAID or AHCI on an Intel? Desktop Board

I know that my laptop has a chipset that supports AHCI.

But I'm worried about the whole...
"Enabling AHCI or RAID after installing the operating system is not recommended or supported when a SATA hard drive is the boot drive. Enabling AHCI or RAID after installing the operating system might cause an immediate blue screen with an 0x0000007b error code, followed by a reboot. If you use AHCI or RAID, enable them before installing the operating system."

SO my question is this....it looks like enabling AHCI is the absolute last thing I should do before installing Windows 7. As in this is the routine I should follow.

1) Back up any drivers/files/etc that I need
2) Insert Windows 7 Installation Disc
3) Close out of pop up install window.
4) Restart Laptop
5) As laptop is restarting enter BIOS
6) Follow Intel's step by step guide for enabling AHCI
7) Change system to "Boot from DVD Drive"
8) SAVE new BIOS Settings....EXIT

At that point my computer should REBOOT and this time it will do so from the DVD drive and Windows 7 installation screen will appear correct?

Hey All,

I'm purchasing a new SSD next week. I've been reading up on it and it looks like I need to enable AHCI in my BIOS. I can't find any option for AHCI though.

I currently have my System setup as RAID0. This was how it was set up in the factory and I haven't changed it.

The only option I have is under SATA operation and I can either set it to "RAID Autodetect/ATA" or "RAID ON".

Is there anyway I can check to see whether AHCI is already enabled? If not will one of the above options enable it?

A:How to Enable AHCI - No option in BIOS.

Some motherboards incorporate AHCI SATA automatically. In the early days of SATA there was a lot of confusion in terminology. "RAID" - "AHCI" - all the same thing.

For your motherboard it looks like you want to choose "RAID Autodetect/ATA" to use a non-RAID setup with AHCI.

Hi all, I searched and was unable to find this specific question answered.

I'm coming from win XP and I've got 3 SATA drives currently operating in IDE mode. I am just about to move to Win7 Pro and I was considering setting the motherboard to recognize the drives as AHCI. I am going to reformat one drive completely for the OS drive.

My questions are:

1. Will this negatively affect my other two storage drives because they had previously been running in IDE mode?

2. Is there a way to determine whether or not my drives support AHCI at all? (They're all SATA drives bought in the last 4 years.)

3. I intend to run XP mode, will AHCI mode pose any problems for this?

Thanks for the help, I've just discovered this forum and it looks like a fantastic resource.

A:Coming from XP, enable AHCI for SATA drives?

ronin688, welcome to the Seven Forums.

Too answer your questions,

1. Not in the slightest. The OS and the driver(s) installed there are what determine whether any attached drives run in AHCI.

2. As far as I know all SATA drives will run in AHCI mode.

3. Won't make any difference as it will be running in a VM, so the host configuration won't affect it.

On the bright side with setting the SATA controllers to SATA/AHCI mode formatting before installing Windows 7, with the motherboard listed in your specs you shouldn't need to install the SATA driver as Windows 7 has native SATA/AHCI support.

If you have any RAID 0 array, you must set SATA=RAID or you're going to ruin your array.
Did you tried to set SATA=AHCI on BIOS then boot in safe mode (F8)? As it boots without drivers, you can look at device manager to check if there is something missing. Then try to reboot normally.

My e5540 came with Win 8.1 Pro and I did a hardware clone to a Crucial MX100 512GB SSD.  I noticed that AHCI was not enabled, so I attempted to enable it.  Windows would not boot with AHCI enabled, but would boot fine when I reverted to RAID in BIOS.
I tried the various tips about registry hacks to no avail.  Eventually I tried to install a fresh Win 7 Pro with AHCI enabled and using UEFI and a GPT partition.  I first disabled Secure Boot and enabled Legacy Option Roms.  Windows seemed to install successfully, but when I shut it down to test a restart, it again found no bootable disk.  I ran across a thread that said Windows 7 could not install a boot loader in GPT.
So with AHCI still enabled, I enabled Legacy boot option in BIOS, booted from the regular DVD (not the UEFI DVD).  Using DISKPART, I ran CLEAN and attempted to install in an MBR partition.  Windows Setup showed a warning that it could not install to the disk because the hardware looked like it couldn't boot from the disk.  I tried to continue and Setup threw an error about being unable to create a System partition.
So I rebooted, went into BIOS and disabled AHCI and selected RAID under SATA options.  I started Windows Setup again and was able to delete the existing partition and let Windows recreated two new ones (one a reserved partition and one primary one).  I went ahead and loaded the Dell AHCI F6 drivers at this point, thinking I would be ab...

A:New Latitude e5540 - Unable to enable AHCI for new SSD

Update: I double checked the Dell website for BIOS updates for my e5540.  I found an A07 BIOS that was a few revs newer than the A04 it was shipped with.   I hassled with creating a bootable USB thumb drive and copied the BIOS exe to it (just Google 'Rufus' for how to do this).  I was able to reboot the e5540 and select the USB via F12 during reboot, and navigate to the BIOS .exe and install it.
After installing the updated BIOS I was able to do a couple things:
1) I was able to install Windows 7 via legacy mode.  Previously, Windows couldn't create a System Partition in this mode.  After the BIOS update, Windows successfully installed.
2) I was able to install Windows 7 via UEFI mode.  Previously, after creating the GPT partition and installing, Windows 7 could not find a bootable device upon reboot.  
I left the new machine in UEFI mode with a GPT partition.  I guess I should have bothered to check for a BIOS update, but honestly - I have had probably 20 computers and rarely had to perform a BIOS update.  This machine was produced less than 8 weeks ago.  The BIOS went from A04 to A07 in that time.  I appreciate the folks who addressed whatever the underlying issues were between A04 and A07, but I am not happy that I wasted a day and a half trying to figure out what the issue was.
I hope my time will save somebody else's time.

Hi Everyone,

I have just installed an SSD into my computer running XP (migration from mechanical drive to SSD was simple with the help of Paragon Migrate OS to SSD). Everything is working ok, however I would ideally like to set my BIOS to AHCI (it is currently set to IDE).

Towards this end I have been trying to follow the tutorial How to enable AHCI after having installed Windwos XP.

I am at a loss concerning how to install AHCI drivers on my ASUS M5A78L-M LX motherboard because it features an ATI chipset on the Southbridge (as can be seen from the CPU-Z screen capture below) -

The instructions in the tutorial specifically focus on an Intel chipset, and they mention that I should be able to right click on each of the "IDE Channel" entries under Device Manager and manually update the driver. However whenever I do this with the appropriate driver (downloaded from the ASUS M5A78L-M LX support page) Windows informs me that it cannot find a "better driver" and leaves the existing one in place!

I have attempted to enable AHCI in the BIOS without following the instructions provided, and was met (not surprisingly) with a BSOD and a quick computer restart. After setting the BIOS back to IDE the computer boots again, so I haven't done any damage to XP (thankfully).

I am now at a loss regarding how to proceed, if anybody has any advise can you please let me know.

Kind Regards,

Davo

I have successfully installed Windows 8 Pro x64 on an ASUS P8Z77-V Deluxe board on a SSD under UEFI/secure boot mode. Used the following settings:
SATA Mode = AHCI
Fastboot = enabled
CSM = enabled
Secureboot = Windows UEFI

Everything works fine. Qcode = AO, performance is excellent etc. System information shows:
BIOS Mode = UEFI
Secure boot state = ON
SSD partitioned to GPT

I now want to create a RAID1 volume on which to store my data. I understand that ideally one has to set SATA mode to RAID before installing windows in order to make the creation of RAID volumes possible.

However, is it possible to convert my present AHCI system to a RAID system without re-installing windows? I heard that some registry settings will do the trick.

A possible alternative kind of RAID1?
I have been checking the user manual of this board and on page 3.39 there is a description of Drive Expert Mode. It can be set to Normal Mode, Super Speed or EZ Backup, where EZ Backup means: "Allows you to use the EZ Backup function that copies and maintains an identical image of data from the SATA6G_E1 drive to the SATA6G_E2 drive".

How different is this from the RAID function set up with Ctr-I? Is it better or worse in terms of fault tolerance and performance?

Many thanks for any advice.

A:Convert AHCI mode to RAID mode without re-installing

On that board, to get full Windows 8 Secure Boot, you have to Disable the CSM. I know it shows "On", but it will show that until you select Other OS in the Secure Boot section. If you have a Video card installed, such as a GTX XXX, it may not yet be Secure Boot capable and will cause the system to abort the boot and put you back in the bios, when the full Secure Boot is in place.

Have you looked into using Storage Spaces as opposed to RAID? There have been some comments about it is not as stable as RAID, but I have no personal info. Maybe some others will have some information.

If you want to change your system to RAID, it can be dangerous, so backup everything you can, and remember, if it doesn't work, set it back to AHCI.

This is not recommend for Windows 7, just in case anyone wanted to try.

When in Windows 8, open msconfig.exe and set the Safe Boot check box on the Boot tab.

Restart your system and use the Del key (for ASUS P8Z77) to get into the bios. Go to advanced settings and change the AHCI to RAID. When you select save, your system will reboot and this time, let it boot into Safe Mode.

While in Safe Mode the drivers will be changed. You can check Device Manager if you like and you will see an entry in Storage Controllers for the Intel Deskto/Workstation... . But you need to open msconfig.exe again and uncheck the Safe Boot box. Then close it and reboot back into normal Windows.

If at any time the system tries to do a repair operation,... Read more

I did it before on a P5WD2-PREMIUM---see this thread:

http://vip.asus.com/forum/view.aspx...=1&model=P5WD2+Premium&page=1&SLanguage=en-us

but there is no SATA controller listed in the Device Manager under the IDE ATA/ATAPI Controller to update--there was one listed in the P5WD2 I successfully converted.

Hello,

I have bought a new SSD which I plan on using as a program drive, though not as OS drive (will reinstall Windows in the next few months). Currently I am running Windows 7 Pro 64bit.

My OS is installed on a Western Digital 2TB drive. It is set to run in IDE Mode currently. My motherboard, an MSI Z87-G43, only has one SATA controller.

I have recently acquired a Crucial M500 240GB SSD. I have it plugged into a SATA 3 slot with a SATA 3 cable. When I booted into the BIOS first, it changed my motherboard to AHCI, so I manually changed it to IDE mode as my OS HDD ran in IDE.

I then booted into Windows, formatted the SSD, and copied some files to it. It appears to be working.

Essentially, I am running on an HDD with my Windows 7 install in IDE mode as well as an SSD running in IDE mode.

I am wondering if it is possible to change from IDE mode to AHCI without reinstalling or corrupting Windows 7 install or any data on either my HDD or SSD?

The tutorial here seems straight forward, though I just wanted to ensure such a process would work in my exact hardware/software configuration:
AHCI : Enable in Windows 7 / Vista

If my hardware/software does not have any issues then I will go ahead and do the registry edits.

Thanks in advance for any help.

A:IDE mode to AHCI mode - can I change it on an OS drive?

Hello ABC190,

If the older Western Digital 2TB drive is a SATA drive, then you shouldn't have any issues changing to use AHCI as per the tutorial.

I just installed an ssd and would like to change the bios utility to ahci however there isnt an area that i am able to do this. the Computer is a Toshiba Satellite Pro A200 (psfa1a-003002).

Do I need to update the BIOS? Where do I get the update and how do I update it?

A:No AHCI in BIOS in Satellite Pro A200

As far as I know BIOS update doesn't offer some additional options. Please check BIOS settings again. In advanced BIOS options there should be SATA option and there you can change between compatibility and AHCI mode.

I have it on my P200. It is almost identical machine but 17? and your is 15? model.

Hi buddy,

I don?t know what Satellite L500D model you have exactly but I can really recommend reading the forum threads firstly before you start a new question. This was already discussed 100 times before?

The AHCI driver you can find in display driver package on official Toshiba website:

A:Where is the AHCI option in Satellite L350D BIOS

Hello

Usually in BIOS there is an option called SATA controller mode. You can choose between AHCI and Compatible mode.

But I believe not all mainboards and BIOS version contain such an option so probably your computer doesn?t offer such an option.

Hi! I hope you can help me =)

I have an Satellite L550D-13V. There was Windows 7 on it, but then I changed the SATA Controller from AHCI to Compatibility in the BIOS settings. I installed Windows XP 64bit then succsessfully but it is very slow. When I change from Compatibility to AHCI again, Windows XP doesnt boot anymore. I see the black screen with the Windows logo for a short time and then there is a bluescreen, very short either, and then the notebook restarts.

What should I do now? Ive heard of installing a AHCI driver, but i cant find one :(

please, forum, help me!

A:Satellite L550D-13V- Bluescreen at switching from IDE to AHCI

Hey,

You can?t switch from compatible to AHCI mode after XP installation. This must be done before you install Windows XP because the AHCI drivers must be installed during Windows XP setup and now it?s too late for this.

The next problem: For Windows XP 64bit there are no drivers and no support from Toshiba. For XP 64bit there aren?t much drivers because it wasn?t popular OS. It?s better using Windows 7 on such a new and powerful notebook.

I would recommend installing Windows 7 again because you can get all drivers for it. I don?t see a reason for using old and outdated Windows XP.

I have windows 7 installed on my desktop, and I recently bought a firecuda 1 terabyte ssdhdd. I connected everything like it was suppose to, but then I tried to put my ssd into ahci mode, and it did a restart then a flash of a blue screen and now nothing loads, it jus loops back to the computer start up screen then nothing after that, sometimes it takes me to the repair screen. I need to know how to fix this issue, because I have six years of pictures, videos, and files on my PC I don't want to lose.

Does Win7 still require AHCI be configured before installation? I think in XP if you switched an SATA drive to AHCI from IDE, you would need to format and start over.

Good afternoon everybody!
I summarize how the issue object of this thread has appeared.

The internal 320 GB broke out due to fatigue. Then, I decided to replace it with a used 500 GB HDD (that is the only minimum HDD capacity found on several marketplaces). The hardware substitution was done easily following a technical tutorial found on the web.

I managed (with many troubles) to reinstalling the original OS (Windows Vista HP) using recovery disks and setting the SATA mode from ?AHCI? to ?Compatibility?. Once the installation steps were completed, I rebooted the system setting another time the ?AHCI? mode from BIOS. Entering the system there was the installation of chipset and HDD driver controllers.

Using the DVDs purchased by Toshiba, I went on performing the Windows 7 HP update. Like Windows Vista, I had to change the SATA mode from ?AHCI? to ?Compatibility? to perform the installation.

Once the installation was completed, like in Vista, I rebooted the system setting changing another time the SATA controller mode to ?AHCI? from BIOS. Now, differently from Vista, I get a blue screen with error ?STOP 0x0000007B? that I could avoid only re-changing the SATA mode to ?Compatibility?.

Other strange thing: booting OS in ?compatibility? the installed software ?Intel Matrix Storage Manager? does not load plug-ins. If I try to upgrade to the newer version downloaded from Toshiba website the installation does not start due to the error ?The computer does not meet the minimum r... Read more

hi, i have recently bought an SSD. I have heard from a youtube video that changing the Sata controller from IDE to AHCI can give me better performance but i tried to enable this and it doesn't recognize the drive. The PC will not boot in AHCI mode which meant i have to switch to IDE again. I have tried booting from the Windows install DVD but it tells me that i cannot install Windows on this drive.
Am i missing something?

Thanks

I have a Sony Vaio and would like to check if it's in IDE or AHCI mode. I entered the Bios but nothing is mentioned in there except some simple settings. My question is how do I establish my laptop is running in which mode and how do I switch between the modes since the Bios don't offer any options? Thanks for reading.

A:How to check IDE or AHCI mode?

Research your motherboard. Google to find the mobo for your computer model, then look on its Support Downloads page for drivers. It will show AHCI drivers if that mode is supportable, or IDE. It may even need a BIOS update to enable more modern AHCI.

You can read the manual to determine for sure. These resources are available on the web for almost every motherboard in existence.

Others will help you with this research, and may already know your mobo, if you fill in your system specs in the bottom left hand corner of your post.

When I installed Windows 8 pro (oem x64) it wouldn't allow me to install with my sata controller set to AHCI mode so I set it to IDE and installed, now I'd like to have trim support so want to enable AHCI. Just enabling AHCI in BIOS boots too a blue :( (blue screen of unhappiness, BSoU??) screen and restarts, leave this to happen a couple of times and recovery mode boots which does not find or fix the problem. Set it back to IDE mode and everything works fine again.

I have tried several registry hacks and had partial success, it booted and worked fine for a couple of restarts but then I got the BSoU again grr. Im not sure which hack it was that "kinda" worked.

Anyone had success with this? Know which hack works? I know some were for rc/cp, rtm?

Hello people, i'm new in this forum so i'm sorry if i shouldn't post in this section
so i just bought a new SSD (850 evo 250gb) And it says on it's software i should enable AHCI mode on my bios
to get it faster. also the tests results show 250 when it was supposed to hit 520-540, and i think it's due to not having
AHCI mode, but i tried to change it in my BIOS, but i only have these 3 options:

- S-ATA+P-ATA
- S-ATA (which is the one i'm using now)
- P-ATA

Isn't there any other way to change it to AHCI mode?
thank you.
