  • check with Sony to see if they have an updated BIOS for you.

  • It is likely enabled by default.  In fact, it might even be intentional to force it on, which would explain why you don't see the option listed.

    -

    Either way, this would be a setting documented in the laptop's user manual/guide if it exists.  Be sure to check for it there.

  • The same issue is seen in HP DV7's.  Some manufacturer's have "dumbed down" their BIOS adjustments.  They lock them to prevent things like overclocking.

  • Hi JGNair,

    Typically you would need to enable RAID in the SATA operation section of the BIOS before installing the OS.

    Then the HDD is in AHCI, RAID ready state as a non-RAID drive. Next, Windows 7 will install the necessary Intel drivers.

    You cannot change to AHCI once you have installed the OS in IDE mode. The system will not boot.

    Sony may have eliminated the RAID feature from the chipset and BIOS when the system was designed.

    If the feature is there, you could create a system image on an external HDD, change the BIOS and perform a system restore using the installation disk with the Windows restore utility. Windows would detect the hardware\BIOS change and add the necessary drivers during the restore process.

    That's a lot of work for a small performance gain. Again, Sony may have dumbed down the chipset as previously mentioned.

    Probably better to leave it in it's current state. If it's not broken, don't fix it.
