Intel RST Driver - old one works, but not the new one (HP i7 11th gen with NVME)

[Josef1975]

Hi everyone, I have this weird problem: I'm building my custom W11 23h2 iso (but the same thing happens with W10 22h2 iso); I have an HP notebook, i7 11th gen, Ssd Nvme, so I need the Intel RST driver (https://www.intel.com/content/www/u...ane-memory-11th-up-to-13th-gen-platforms.html)

the old one (19.5.2.xxx) work as expected, the last one (20.0.0.xxx) absolutely not (can't see any ssd drive during setup).
I know I can disable RST in bios, and also the old driver work perfectly, but I'd like to understand this strange behavior.

thanks to everyone for help.

update: on new hp desktop with i3 12th gen both driver works... so new one has problem on 11th gen?

Intel RST driver versions can be a problem with some PC's. Sometimes you need a different version than the Windows default driver, or the one that Windows Update tries to install for you.

There's often an issue with driver ranking, or how Windows selects which driver to load at boot time. Windows picks from a combination of the most specific HW ID driver match, and by release date. The release date can be misleading, since a driver might be updated for an unrelated security issue or bug fix, but isn't intended to replace another driver set.

Possible workarounds:
1. Remove the Intel RST drivers that ship in install.wim (iastorv.inf or iastorav.inf).
2. Integrate your own set of correct drivers.
3. Disable driver updates from Windows Update to prevent unwanted replacements.

thank for the reply... anyway, mistery solved: despite what intel say on his site, driver version 19.xx support 11,12,13th gen cpu; the new version (20.xx) dropped support for 11th gen (but add 14th gen).
evidently, every version of RST driver usually cover 3 generations of chipset/cpu... so it can be a bit confusing to choose the right driver...
and if you are building an iso to be used in many different pc could be a problem (you can integrate only one version of the driver of course)
