Activating AHCI on 890GX Extreme4 for SSD?

[Tregonsee]

I have two HDs (not-RAID), and a DVD drive, all SATA3 installed. The current BIOS settings are:

SATA Mode IDE
SATA IDE Combined Mode Enable

I have added a Samsung SSD, and have it working except that the docs and configuration software recommend switching to AHCI for best performance. If I switch the SATA mode to AHCI, the only drive which shows is the SSD.

Any suggestions, or additional information needed?

I heard from ASRock support. It was a little cryptic suggesting that I get the latest BIOS and so far as I could understand, telling me to ignore the situation and just go ahead. I updated the BIOS which had no effect, but after making the change which required some new drivers being loader by Windows, everything worked fine. Stll odd that all the drives are not visible.

When you first isn't up the machine, isthe bios set to operate in ahci.or ide
Mode.

You can not change the drive mode after installing the windows os. It puts a reserve partition on the c: drive that ties it to that mode. Just stay with IDE or re-install the os.

I am still wondering why isn't there a easier way to switch between AHCI or IDE mode. Windows just by default install the selected driver (either AHCI or IDE). If and only if it can install both drivers during installation, it will make switching much easier from IDE to AHCI or back to IDE.

It's like the old days when you boot two different windows operating system, but the boot loader was only on one partition. If the partition was made unavailable, the other drive was useless. So when a drive is setup with an AHCI bootloader, it's not available in another mode, switch to Raid & it will do this for sure, I have not tried it with IDE but I'm sure that is the case.

Exactly that is the issue with modern PCs. These old problem still persists for over 15 yrs and there is no one time solution to it.
