    hey all,

    full system is listed in sig. I have 2 seagate 500GB 7200.11 hard drives that are NCQ compatible, and I just want to try it out for myself to see if it makes any speed difference. I know I need to enable AHCI in the BIOS, but I googled before doing this and sure enough you have to make a small change to your registry to enable windows to use a different driver file for your hard drives. For most people, this seems to work perfectly fine. However, I changed my registry key, and enabled AHCI in the BIOS - system detects all my hard drives fine, but then tries to boot to the LAN adapter without recognizing the boot drive. I also cannot install intel matrix storage manager for some reason, even though I have seen screenshots of it working perfectly fine on windows 7 RC.

    Any ideas why it won't boot?

    Cheers

    I've done the switch to AHCI. You need to make the registry edit, shutdown, switch the BIOS to AHCI mode, and then turn the PC back on. Is this the order you went through?

    Indeed, but this results in a no boot. It just doesn't detect the boot drive. It knows the drives are there, as it lists them upon POST, but once it gets to the boot stage it just tries to boot from LAN.

    If your sure that the boot order in your BIOS doesn't have the LAN set as the first option then try disabling the LAN in the BIOS. This should make the computer skip the LAN and hopefully boot from your HD.
