Problems with 1 bootdisk + 2 disks in raid1

  1. Hey There,

    This my first raid system so, i just bought a new intel D975XBX supporting Raid 0, 1 and 5.

    I have 3 disks: 1 Maxtor 300gb for booting, and 2 WD 320 for mirroring (Raid0)

    I installed the OS on the Maxtor - everything fine here!

    When i tried to change de Bios and i put it in raid mode( to access the WD and config in raid 0) the pc does´t boot. I think i understand that - the bios is assuming that all drives in the sata ports are a single raid, and they really aren´t.

    What i have here is a mix of sata and raid, can i have that?? i tried everything

    Need help here!!

    PS: MOBO supports

    Four Serial ATA interfaces with RAID support (four additional interfaces available with optional discrete RAID controller)

    One parallel ATA IDE interface with UDMA 33, ATA-66/100 support

    RAID 0 is striping, RAID 1 is mirroring. Which do you have?

    With three drives, you should look into RAID 5... It's pretty neat, utilizes all three drives in a single RAID and is better than RAID 1 in several respects.

    The BIOS won't really assume anything you don't specify. In your RAID BIOS, you should be able to create a RAID configuration. Then in the regular system bIOS, set your boot order correctly to boot from your RAID.

    For several reasons, I want to use only two disks therefore Raid 1 is my choice (for mirroring).
    The other Sata has the OS.

    Is this possible? Can I create a RAID configuration in the RAID BIOS and in the regular BIOS set it to Boot from the SATA?

    Thanks in advanced for the help
