  1. I have one Sata drive and one IDE
    I need to boot to Sata
    I have set the BIOS to do this and it does ONCE only

    Each time I turn pc on or restart it defaults to the IDE

    Please help not sure what to do now

    It's most likely the small cmos button battery requires replacing
    If this is a Desktop computer you will need to download the free service\operational manual from your computer's (if brand name) or Motherboard's home support site
    This will help in locating this cmos battery, and also advise you on electrical and anti-static precautions

    Please replace the CMOS battery

    TY Kim
    I think I was perhaps choosing the wrong menu to set boot order.:eek:
    I did change the battery .. no change

    When I boot pc (desktop) I have the choices of
    Boot Menu (Esc)
    Setup (F1)

    So I was choosing boot menu as I did not even notice the Setup choice
    Is Boot menu just another option for occasional changes in the boot order? and then upon reboot it goes back to the default?

    Anyway I did go into Setup and I have it setup and saved now properly in the bios.
    Also I realized my IDE drive was on cable select I have now switched it to slave.

    Not really certain if it was changing both that corrected the error but I know for sure the IDE in the bios WAS set as master

    Thank You for your help I had never even suspected the battery but I now see that could be an issue.

    Yes that setting "Boot Menu (Esc)" is for occasional change of boot order
    To save the boot setting fo all time, then as you have discovered, you will need to go into Bios setup, change the boot order, then Save and Exit.

    Regarding the Master\Slave jumper, found only on ATA (or IDE) connected Harddrives
    Since about 10yrs ago (probably more now!) all Drives should be jumpered as CS (Cable Select) Unless your Drive or Bios version is very old.

    Thanks again Kim IThis has drivven me crazy for a week now lol Wish I had found forum sooner and umm perhaps read the screen more thoroughly. I have been into BIO a million times over the years and this boot screen suprised me I just thought it was the simpler way to do it ugh lol

    I have read on another forum to not use the CS when using an IDE with a sata so that is why i did that also. So not sure now but I think I best just leave it as it is all working finally.

    Thanks again :) what would I do without these forums
