    Default EP45-UD3R bios settings for mixture of SSD, SATA, and IDE drives

    Hi folks I just did a clean install after adding a new SSD as the system drive, but unfortunately was not aware of the necessity of changing the bios for AHCI beforehand. I know there is a need to change some registry values before changing the bios, but am also wondering about the "sata port 0-3 native mode". Also, will enabling AHCI mode work with a mixture of HDD and IDE drives? Yeah, I really should ditch the IDE drive as it's not very big, but it's serving a purpose for now (running ProTools DAW).
    Thanks in advance for any help,
    Climber

    Your board has two SATA/drive controllers, the Intel ICH10R and the Gigabyte SATA II chips. They are separate, do not interact or affect each other, and are configured individually.

    The Intel ICH10R SATA controller chip only controls the SATA2_0 to SATA2_5 ports. The Gigabyte SATA II chip controls the GSATA_0 and 1 SATA ports, and the single IDE port only.

    Configuring AHCI on the Intel ICH10R chip has no affect on the IDE port, and any settings on the Gigabyte SATA chip do not affect the Intel chip. So they can be used at the same time, configured for different uses.

    Be certain to put your SSD on the Intel SATA ports, configured for AHCI mode. The manual section that describes the SATA and IDE options labels which chip is being configured.

    The SATA Port0-3 Native Mode option might only be displayed if the Intel SATA mode is set to IDE, so not displayed if set to AHCI. If this option is still shown when using AHCI mode, set it to Enabled. The Native and Legacy mode thing is only valid for XP and maybe Vista, but not Windows 7, which should use Native mode.
