    Default AHCI, SATA, Windows XP and ICH9M

    I'm a little lost about how to make sure SATA drivers are loaded while I'm installing Windows so I can use it in SATA mode and not IDE-emulated.

    I'm trying to slipstream the Intel Storage Matrix Manager into nLite under the Drivers section but nLite isn't recognising the file, and from what I've read I should be integrating three files called aahci.inf, something, and something else. The ISMM folder doesn't have any *.inf files, so where am I supposed to download the driver with the aachi.inf and others?

    Also, I read somewhere else that ICH9M no longer uses AHCI? In that case, what am I supposed to do?

    Download this (XP 32-bit). It should have the INFs (iaAHCI). Slipstream it.

    In that link provided, here's what it supports:

    Code:
    PCI\VEN_8086&DEV_2681&CC_0106.DeviceDesc    = "Intel(R) ESB2 SATA AHCI Controller"
    PCI\VEN_8086&DEV_27C1&CC_0106.DeviceDesc    = "Intel(R) ICH7R/DH SATA AHCI Controller"
    PCI\VEN_8086&DEV_27C5&CC_0106.DeviceDesc    = "Intel(R) ICH7M/MDH SATA AHCI Controller"
    PCI\VEN_8086&DEV_2821&CC_0106.DeviceDesc    = "Intel(R) ICH8R/DH/DO SATA AHCI Controller"
    PCI\VEN_8086&DEV_2829&CC_0106.DeviceDesc    = "Intel(R) ICH8M-E/M SATA AHCI Controller"
    PCI\VEN_8086&DEV_2922&CC_0106.DeviceDesc    = "Intel(R) ICH9R/DO/DH SATA AHCI Controller"
    PCI\VEN_8086&DEV_2929&CC_0106.DeviceDesc    = "Intel(R) ICH9M-E/M SATA AHCI Controller"
    PCI\VEN_8086&DEV_3A02&CC_0106.DeviceDesc    = "Intel(R) ICH10D/DO SATA AHCI Controller"
    PCI\VEN_8086&DEV_3A22&CC_0106.DeviceDesc    = "Intel(R) ICH10R SATA AHCI Controller"
    Looks like you're good to go with it.

    why are you bothering with ahci? degrades performance.. i mean do you need ncq or hot plugging?

    Enabling AHCI does not degrade performance. Running the HDD in IDE mode results in about a 5-10% loss in performance.

    No actually for normal usage IDE emulation is marginally, possibly insignificantly faster than AHCI.

    NCQ is only faster for random read/write tasks (iirc), which is why I want to enable it.

    My HDD....AHCI enabled and IDE mode
    NCQ generally slows performance very slightly in a non-server environment
