Issues from Switching RST To ACHI

[aiman6444]

Hi, I’m using an HP 15s-fq2658TU (6C0G9PA#UUF) with an Intel Core i3-1115G4 and BIOS version F.41.

My storage is currently running on Intel RST (VMD), and I want to switch to AHCI mode.

Problem:
There is NO AHCI or SATA mode option in my BIOS. I checked:
- UEFI HII Configuration
- BIOS Configuration menus
- No VMD toggle or storage mode settings available

What I’ve tried:
- Looked through all BIOS menus
- Attempted to find VMD or RAID settings
- Tried basic changes but nothing appears

Questions:
1. Is AHCI hidden/locked on this HP model?
2. Is there any safe way to disable Intel VMD?
3. Do I need a modded BIOS to access AHCI?
4. Or is this system permanently restricted to Intel RST?

Goal:
I want to run AHCI for compatibility with other operating systems / avoid RST dependency.

Any help or confirmation would be appreciated.

Hi:

What you want to do is not possible.

The parts list for your notebook indicates that it comes with a 512 GB NVMe SSD.

HP PartSurfer

NVMe SSDs use an entirely different storage controller called a NVMe storage controller, which can be found under the Storage controllers device manager category.

AHCI is only used for SATA 3.5" or 2.5" mechanical hard drives, SATA M.2 SSDs and SATA 2.5" SSDs.

Your notebook's M.2 slot does not support M.2 SATA SSDs.

Since 2.5" SATA drives are not supported in the model series either, you will have to live with the way things are.

I am attempting to install Hackintosh or Chromeos Flex, but I am encountering an issue where the installer cannot detect my storage device due to Intel RST (Rapid Storage Technology).

My system is equipped with an NVMe SSD (Samsung MZVLQ512HBLU-00BH1), and it appears that the Intel RST/VMD configuration is preventing proper recognition of the drive during installation.

Could you please advise if there is any method to resolve this issue or work around the Intel RST limitation so that I can successfully install the software?

There's nothing I know of that you can do unless the folks that support Hackintosh or Chromeos Flex have the Intel storage controller drivers you need to install for the OS to detect the NVMe SSD.

I've zipped up and attached the Intel storage controller drivers for Windows below, so you can see what they look like.
