15.5 and 15.9 are completely different development branches. Furthermore: The BIOS module should never belong to a newer development branch than the in-use RAID driver. The v15.5 driver knows nothing about the functionality of the v15.9 BIOS module.
EFI Intel RST VMD Driver 19.0.1.5466
I think the VMD file is replacing the SATA file. The Z690 BIOS no longer has EFI Intel RST for SATA, only EFI Intel RST VMD.
… and in a way that is completely incomprehensible to me, an old OROM file (branch 17.3.x.xxxx) is used by all manufacturers. 
The old website has newer 7.7.0 VROC modules. I don’t have permission to post multiple links.

@Monstieur
Welcome to the Win-RAID Forum!
AFAIK the latest Intel RSTe EFI VROC “RaidDriver” modules from the v7 platform are the v7.7.0.1054 ones, which I am offering within the start post of this thread.
As you can see >here<, the former Win-RAID Forum hasn’t offered newer ones.
Enjoy the new Forum!

ASRock has updated some EFI drivers on their 6xx-series motherboards.
Here’s Intel RST EFI RaidDriver 19.5.0.5645

Thanks for the new RST v19 platform Intel EFI VMD BIOS module. It is now linked within the start post of this thread.
@all interested Forum members
Although the start post of this thread is up-to-date regarding the links to the latest Intel EFI RaidDriver and VmdDriver modules, it urgently needs a complete renewal. Due to the Forum move from Xobor to Level1techs the formatting has become very ugly. Furthermore many links to the old modules do not work anymore, because they are either outdated or linked to an FTP Server, which I don’t use anymore.
Who is able and willing to start a new thread about this topic? Interested Forum members should send me a PM.
Dear Forum members and visitors,
since the start post of this thread was not usable anymore due to the broken links and the irritating formatting, I have spent the last 2 days for a complete manually done reconstruction of it.
It was a horrible and nerve-wracking experience for me!
Now I know why nobody replied to my last post. 
If anyone among you should find a mistake or a broken link within the updated start post, please let me know it.

VROC 8.0.0.4006 (Intel SPR, PCH C741)
UBU names files incorrectly. There is now tSATA, not just sSATA. No OROM.
Otherwise, I don’t think there’s much point in bothering with this line. VROC requires a paid key and unfortunately it doesn’t work as it should. This was a pretty bad decision on Intel’s part.
