AHCI Bios Setup For SSD?
Jan 10, 2012
I have a SSD drive & want to use the AHCI Mode & Native Command Quening from Windows 7 Pro X64. I performed the Regedit by setting the START paramater in the registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesmsahci from "3" to "0" - and then making the switch in the BIOS from IDE to AHCI. Windows still would not load! The Bios screen would not load Windows 7.I have a Gigabyte GA-EP45-UD3R Board that has a Intel P45 Chipset & I installed the latest Intel Sata drivers before I tried the change. I had to use my Acronis True Image program to get Windows 7 back up & running.My Board has 6 Intel Sata ports & two Gigabyte ports on the board. I don't use the Gigabyte ports & they were left in the IDE mode in the Bios when it failed.The Bios screen loaded differently but failed as I said to load Windows 7.If I perform a clean install will Windows 7 load & install in the AHCI/Native modes with the bios setting to AHCI & not IDE? I have the SSD for programs & a 1TB HDD for storage & backup.

Anyone who knows how to configure AHCI in bios? I'm confused I must say. I want to have eSATA with a sata slot from my motherboard.

I have a new computer. When it boots up, I see AHCI Bios not installed. I do not know much about the workings of a computer. What does AHCI Bios not installed mean? My computer runs on Windows 7 and so far it seems to work just fine.

I'm trying to do a startup repair of Windows 7 x64 on an SSD but can't boot from the CD-ROM while in AHCI mode. I have set CD-ROM at the top of the boot order in BIOS but this is just ignored and the computer boots from the SSD with the knackered version of W7x64. I read somewhere that when in AHCI mode, the BIOS boot order may include "CD-ROM" but it's not the real device anymore. I tried looking for the CD-ROM by its manufacturer name in the list under Hard Drives but it's not there either.So just how do I go about booting from the CD-ROM in AHCI mode? No problems booting if I set the BIOS back to IDE mode, install Windows 7 and then do the registry hack to install the AHCI drivers, but I'd like to be able to boot from the CD-ROM in AHCI mode.
P.S. I have a Gigabyte GA-MA78GM-US2H motherboard and am using the latest BIOS version (F9D)

I want to install Windows 7 on a clean drive.... but I cant even get to the install options, because the drive is not recognized when i turn on the machine. It stalls, even before I can get into the BIOS settings.I need to manuallly disconnect the drive > then change back to IDE mode inside the bios and now I am able to install Windows.The funny thing... I have a backup image of a running Windows 7 installation and if I copy it onto the exactly same drive it runs without problems in AHCI mode another weird thing.... i already installed Windows 7 in IDE mode and thought that maybe later, once the installation is done i could switch back to AHCI.well, same thing.... once ahci mode was enabled in the bios, the drive was not recognized anymore.i also tried to install the chipset drivers from within windows and got a "the system does not meet the minumum requirements."

I have just fitted a SSD drive in my computer windows 7 64 bit system, when I installed windows onto the new SSD I just unplugged my old hard drive and fitted the SSD and just installed windows 7 and all worked ok. But after the new install was working I was told I needed to make a change in the BIOS to alter the settings from treat Sata as IDE to treat Sata as AHCI. I did this and all was ok with the new drive the installation worked and the new drive is running ok.
But now I have since read that I should have made the bios change before installing windows nad should not be done after the install, So do I need to reinstall windows 7 with the bios changes to treat sata as AHCI before I install or will it work ok it seems to be ok but im not sure now. I was also under the impression that I could still have my old hard drive fitted and just select the hard drive I wanted to boot from as the computer started, I wanted to do this so.
I could still has access to all my old stuff if I needed it. But now my old hard drive will not boot until I change the Bios back to treat Sata as IDE, so is this not going to work or will I have to change the bios each time I need access to my old drive. Also I have an Asus P6T SE motherboard so can I plug the SSD into any Sata port or is it better to plug it into number 1 if so how do I find which one is number one.

I have recently installed a Crucial M4 256 GB SSD in an Acer Aspire 5742 laptop as a replacement for it's aging HDD. This was followed by a clean install of Windows 7 Home Premium 64 bit on the new drive.
So my next step is to ensure that the system has all of the appropriate and up to date drivers installed. Most of the relevant information I found on the Acer website:
[URL]
I am familiar with most of the device drivers listed here and don't expect to have any trouble tracking down the best versions currently available but I am not sure about the "Intel SATA AHCI" driver in particular. It has been my understanding that to enable TRIM on an SSD dedicated as the system drive you just have to set SATA mode in BIOS to AHCI and windows will take care of the drivers during install of the OS.
So my question is will I see any benefit in installing the latest Intel AHCI driver (ver 11.6.0.1030) over the MS one originally installed with Windows?
Alternatively is it a better idea to leave the configuration as it is (working pretty well) and avoid potential software conflicts?

Im installing a new SSD and i wanted to use it as an oppertunity to change everything over to AHCI and wanted to clarify one thing before i went ahead. Im going to change the setting to AHCI in the bios and then install windows 7 on the SSD. Once i get into windows i was going to plug in the old Hard drives. With the old hard drives being used when my computer was on IDE will they be able to be read or will all the data be lost.

I just changed my disk setup from:
1 SATA HDD Primary OS Disk
2x SATA HDD Backup Disks in RAID 1
TO:
1 SATA SSD Primary OS Disk
1 SATA HDD Backup Disk
[No RAID]
Everything worked great, no problem. So, since I don't have a RAID array anymore, I decided that I could change my BIOS setting to AHCI instead of RAID. I have a Gigabyte GA-P35-DS3R v1.0 mobo.
These are my steps:Settings > Integrated Peripherals > "SATA RAID/AHCI Mode" = RAID
--> Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome
Next Step:Launch BIOS settings Integrated Peripherals > "Onboard SATA/IDE Ctrl Mode" = RAID
--> Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome
Switch both settings back to RAID, reboot, and Windows starts up just fine, no issues.
What am I missing? Why can't I set it to AHCI mode without BSODs?

I have two SATA hard drives. I was poking around in the BIOS yesterday and noticed that they were setup IDE instead of AHCI. I am not sure what either does and did not want to change anything without asking. When I first got my PC, it had XP installed, so I am thinking that is why IDE is set. Do I need to change it to AHCI? I am not having any problems. Would it be of any great advantage to change it? I understand that after the OS is installed, it is a problem to switch to AHCI.

I have the GA-EX58-Extreme Board and have just installed the pre release of Windows 7 7600 64 bit. Normally i have experience to get the BSOD when in staling with AHCI active in bios so i change to IDE mode. Installation went flawless and also the change to AHCI mode on Intel ICH10R controler went normal.
As always i got problem to change the J micron controller to AHCI and of cause i got the BSOD again. I installed the latest R1.17.48.16 driver and tryed again but no luck. Can some tell me what i am doing wrong. ? I have a hardisk and a dvd drive attached to the J micron Sata connection.

I was working in Outlook 2010 this morning.I clicked on an e-mail and the mouse was disabled.I was unable to do anything and then the BIOS setup screen came up.I escaped and did a normal startup from the Windows screen that came up and was able to work normally and shut down normally. How should I diagnose and address the problem? I was using a Pentium 5 Toshiba laptop running Windows 7 Home Professional.

I recently read an article about using a USB thumb drive to install Windows 7.Set Up a USB Drive as a Bootable Device to Install Windows 7 IT Professionals.I would like more information about how to do this. After reading the article the questions I had were:Where do I get the Windows 7b ISO file? Can I make it from my present install disk or do I have to buy it? How do I setup my bios to be able to install from a USB device? I am not sure that is possible on the PC I have.

I have a real problem booting with my Restore CD. It doesn't let me go further then the bios. It tells me I can select ESC and it will give me the boot selection pop up, and when I do that it only says that boot selection has been selected but doesn't work. It also gives me an option to select F2 for setup but takes me straight to the bios. I set CD/DVD as first boot priority but it didn't work.

I am getting ready to set up a RAID Array but this is my first time doing anything with RAID. I know how to get into the BIOS and change settings and I know with two hard drives, I should do RAID 1. However, I just have a few questions before I do this. First off, I am an idiot and did not notice that my first hard drive I got when I built the computer has a 32 MB Cache:
Caviar Blue 1TB 7,200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive WD10EALX - OEM
I noticed it only had a 32 MB CACHE when I went to get another one. I then asked for the version with a 64 MB CACHE (WD1002FAEX), paid for it and left. Will these two hard drives work together in RAID if they have different sized caches?

I need to install either windows XP or windows 7 on my USB stick so I can boot my computer from the USB and use it like a normal installation. Articles I read tell you how to install Windows on a USB but not how to allow your computer to boot from the USB like it would be a HDD. I know how to set up my BIOS and I don't need an explanation in that respect I just need a step by step guide or at least a good guide on how to install either XP or 7 onto a USB, not from I've done that 1,000,000 times.

anyways, my main drive is a RAID 0 with Vista x64, but I have a second HD that is a SATA 250GB, which I installed Windows 7 on. The only way I could get install to work was to switch my BIOS to IDE mode rather than RAID. I would of course though, like to be able to access my Vista drive from Windows 7 (and more importantly, not have to switch between IDE/RAID mode at all in the BIOS, it's a pain).
Now, the one odd this about this all is that the drivers I have for Vista (x86/x64 drivers) for this mobo's RAID controller WORK when loaded on installation to identify and install to the drive, but seem to not load or not work in any way once the first reboot on install occurs. Maybe this is because I installed from within Vista x64, though.
(Incedentally, my motherboard is an M3A Asus, using ATI's SB600 for a RAID controller)
I've tried loading the drivers from within Windows 7 while in IDE mode, but the install program won't let me. At first it didn't allow because of version restrictions, but then I altered the ini file to get around that, but it encounters some sort of error when installing and quits.
Any help that can be offered, would be grateful. I realise it's a beta and not a real release, so I can get past the BSOD from my odd setup, and I really am enjoying playing around with it so far. Very very impressed.
Edit: Just in case anyone thinks of suggesting me to right-click the inf file and install that way, already tried, won't allow for it.

I've got an Acer Model As5742 Laptop with an i5 480M processor and 8 GB of good Ram. I'm running Win 7 Pro 64 Bit. It's only about 5 months old and this started about a month ago. I have no other problems. IE: Blue Screens or Lockups or anything, just the Bios clock changes to a random date and time after every restart. I replaced the Bios battery twice and it only effects the chore of having to reset the time in Windows every time I boot.
I'm going to send it to Acer to be repaired within a week or two, but maybe it's not a bad timing mechanism in the motherboard and one of you people have a correct solution to it. Which will save me the trouble of sending it in for a motherboard replacement.
I do have all the drivers and bios updates installed. Oh yes I've ran about 15 different virus Etc. Malware scans with several different products and they all come back clean. I ran System File Checker SFC /scannow from the command prompt several times that also comes back OK.

one of the netbooks was plugged in to initially power it up, but then hard-shut-down before Windows could run through its initial setup.Now when I boot up the netbook, and it attempts to go through the initial windows setup "Setup is starting services", and then throws an error message: The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install Windows, click "OK" to restart the computer, and then restart the installation.I restart, and the cycle continues. This happens whether I try to boot normally or in safe modeI've got no CD-drive attached to it, so I'm not sure what I can do to break this error cycle.
