ASUS BIOS: access SATA options

Hello,

A few months ago, I updated the BIOS of my Asus Z790-Pro-Wifi motherboard to version 1825 dated 09/10/2025.

Stable, but the BIOS SATA options are no longer directly visible, which is confirmed by this video:

https://www.youtube.com/watch?v=yL73D_m2Y3o

they are now well hidden (and only appear when disabling "VMD"), and for me you have to go to:

Advanced->System Agent (SA) Configuration, then Disable "VMD", and in principle the SATA options (allowing automatic detection of SATA drives as soon as they are connected to the motherboard) will appear.

Or if I want to set "VMD" to Disabled, the BIOS tells me that disabling VMD "presents a risk of data loss".

So before disabling it, I would like your opinion! I should note that I do not have RAID on my PC.

Thank you

P.S.: I need to enable automatic detection of SATA drives, because I use a 5.25" bay in the case, allowing hot-swapping drives.

    Hello,

    It seems to me that VMD technology is intended to bypass the need for an Intel RST driver and specifically NVMe SSDs.

    There is a risk of data loss only on RAID drives whose data would be lost.

    It seems to me that only the RAID volumes are affected by this VMD; but I’m not sure.

    I obviously have an NVMe as the Windows system drive, and that’s why I’m a bit "worried" about disabling it, but I don’t see how to do it any other way?
