    Default GA-MA770T-UD3P - Slave IDE device not detected when SATA in AHCI/RAID mode

    I have a problem with enabling SATA AHCI mode in BIOS. At the beginning I must say that this problem doesn't appear when using SATA in IDE mode.

    After I enable SATA AHCI mode, BIOS is unable to detect slave device attached to IDE controller (master is detected). It does not matter whether HDD is master and DVD slave or vice-versa. BIOS is just stuck while detecting slave device for long time and then says "None". Interesting is that the problem appears only when performing cold start. Slave device is correctly detected after restart.



    I have already contacted official Gigabyte support but I wasn't satisfied with answer, so I'm trying to ask here. Thank you.

    You can't have a hard drive and IDE drive on the same cable in AHCI mode, I am not sure why this is but I have seen it happen often.

    Your best bet if you have to keep both of those IDE devices is to leave things in IDE mode, otherwise you will need to remove the IDE Hard drive or get a SATA CD/DVD drive.

    SATA CD/DVD drives are fairly cheap, you can get one for $20 or so, less if you can use ebay.

    Thank you for your answer.

    Interesting thing is that when BIOS is stuck at that "Detecting IDE devices..." and I press Ctrl+Alt+Del, system restarts and both devices are found immediately then. Also when restarting Windows, both devices are found. Problem appears only on cold start.

    Gigabyte support sent me new BIOS ver 8a for test (http://ggts.gigabyte.eu/FileList/923079/ma77tud3.f8a). But I don't want to flash it unless someone tries that flashing this version is without problems.

    Ahh ok, I missed the cold boot part.

    Flashing beta BIOS is fine, I only use Beta BIOS myself.

    Please DO NOT USE @BIOS to flash with, use Qflash or DOS, here is a guide

    So I have updated BIOS using Qflash utility, but problem hasn't been solved.

    I guess I have to use IDE mode now and buy SATA DVD-RW soon.

    Did you load and apply optimized defaults after you flashed?

    Also, when flashing did you disable "Keep DMI Data"? If not you may want to do that again, or fully clear your CMOS for 20 minutes and then load optimized again.

    That of course will only help if there is a fix in the BIOS that should work, if there isn't it wont matter and you will just need to use IDE until you get a SATA CD/DVD

    Optimized defaults have been loaded after flashing.

    I must admit that I'm not sure about DMI, because I didn't notice such option in Q-Flash. I know it's in @BIOS (where it is set NOT to clear) which I used in the past to flash from F3 to F7. Now I used Q-Flash.

    It's in Qflash, right above Load optimized. You have to use the PgUp/PgDn keys to change it.

    It may not matter though, just clear your CMOS for a while then try optimized again and see if things remain the same or not.

    When using AHCI, did you test Native mode enabled and disabled?

    I cleared the CMOS (by putting jumper on "Clear CMOS" pins), then loaded optimized defaults. It didn't solve the problem.

    What do you mean by "test Native mode enabled and disabled" ? There's options AHCI, RAID, Native IDE. The first two have problem, the third one doesn't.

    Well it looks like you will just need to keep this on IDE until you can get a SATA CD/DVD Drive
