SATA controller AHCI mode questions
I read and I understand what AHCI is and what it's benefits are. I
understand that switching the SATA mode after Windows XP is installed can cause problems. Regarding the BIOS setting "SATA Configuration": Is there any downside to setting the ICH10R ports to AHCI mode? (*Before* XP installation, of course). My setup will be 2 Sata HDDs and one Sata ODD on ICH10R. If the setting is to RAID (as Intel recommends, which activates AHCI also), and I do not set up any RAID array, will that affect the normal operation of the system? Or is it just "RAID ready" so to speak? Any Downside to this using setting? On a secondary controller (JMicron JMB363 or JMB322) would setting this controller to AHCI have any affect on the PATA connection (which is on the same chip)? Would a standard EIDE hard drive or ODD still work if this controller is set to AHCI? In "SATA Configuration" there is a setting: "IDE Detect Timeout (Sec) [35]" and "AHCI CD/DVD Boot Timeout (Sec) [35]" . What is the purpose of these settings? Any harm in lowering the timeout(s)? |

Very driver specific and OS intolerant (done right or not at all) according to wiki - Enabling AHCI in a system's BIOS will cause a 0x7B Blue Screen of Death STOP error (INACCESSIBLE_BOOT_DEVICE) on installations of Windows XP and Windows Vista where AHCI/RAID drivers for that system's chipset are not installed; i.e., boot failure.[5] Switching the chipset to AHCI mode involves changing the BIOS settings and will not work. Usually, manual installation of new drivers is required before enabling AHCI in BIOS.[6] Alternatively, a "Repair" installation with the appropriate driver loaded during the setup process usually corrects the problem. For motherboards with more than one Sata controller (for example, some boards have Intel and Jmicron Sata controllers) another alternative is possible. The sata cable for the boot drive can be inserted into a port on one controller (which can be configured in IDE mode), allowing the machine to boot successfully with the other controller configured for AHCI mode. The AHCI drivers can then be installed in windows without difficulty before swapping the cable back. |

It is my understanding that the wording refers to already installed versions of the OS - versions that were installed in IDE mode and then converted in BIOS to AHCI afterwards. Further reading seems to confirm this. One user "was able to force the installation of the drivers" to work around the problem. But in any case it seems to be quite important to choose a mode at first build and stick with it. Thus the annoying questions. |

had a flock of green cheek conures squawk out: I read and I understand what AHCI is and what it's benefits are. I understand that switching the SATA mode after Windows XP is installed can cause problems. Regarding the BIOS setting "SATA Configuration": Is there any downside to setting the ICH10R ports to AHCI mode? (*Before* XP installation, of course). My setup will be 2 Sata HDDs and one Sata ODD on ICH10R. If you don't slipstream the drivers, you'll need a floppy with the drivers. I use nLite. www.nliteos.com If the setting is to RAID (as Intel recommends, which activates AHCI also), and I do not set up any RAID array, will that affect the normal operation of the system? Or is it just "RAID ready" so to speak? Any Downside to this using setting? No, the drives and os won't care. On a secondary controller (JMicron JMB363 or JMB322) would setting this controller to AHCI have any affect on the PATA connection (which is on the same chip)? Would a standard EIDE hard drive or ODD still work if this controller is set to AHCI? Won't affect the PATA. In "SATA Configuration" there is a setting: "IDE Detect Timeout (Sec) [35]" and "AHCI CD/DVD Boot Timeout (Sec) [35]" . What is the purpose of these settings? Any harm in lowering the timeout(s)? The ide timeout: how long the bios waits for the drive to get ready. The dvd timeout: a delay to allow the drive time to recognize a disc. On my Asus P5Q-EM, the dvd timeout is only used when dvd is first in the boot order. |

Before or after the OS install? After. Saves having to mess about inserting a driver disk during installation. -- Conor I only please one person per day. Today is not your day. Tomorrow isn't looking good either. - Scott Adams |
