I have a Dell Precision Tower 5810 with Intel Xeon CPU E5-1620 v3 processors running Windows 10 64 bits latest release. This computer has a C600/C600+/C220 Series Chipset X99 controller., and I have three SATA disks connected there: one SATA SSD for OS and APPS and two additional SATA disks in a RAID 1 configuration. Initially I was having Dell recommended Intel RSTe Drivers (it was version 3.6 or 3.5 I don’t remember exactly) but with the two different controllers: Intel SATA AHCI and Intel SATA RAID present in the system.
Despite that I know that the processor is not officially supported by Windows 11, I use t AllowUpgradesWithUnsupportedTPMOrCPU Microsoft Official hack for circumventing this requirement and the iupgrade goes smoothly till the 1st OS boot, during this first boot Windows 11 shows a BSOD complaining about IaStorA.sys driver, then it rolls back the OS installation to the original windows 10.
I have updated my drivers to the latest versions available in these forums for each platform (v.4.x, v.5.x, v6.x, v.7.x) ; I have also reconfigured my system to use Standard MS drivers for AHCI and the Intel specific ones for RAID controller, but the result is always the same BSOD because of IAstorX.sys driver and rollback of the upgrade. I’m currently running version 126.96.36.1990 of the drivers.
Any idea about this issue?. Has anyone been able to upgrade to Windows 11 using a similar config with X99 controller? Thanks in advance for the support and help
Edit by Fernando: Thread moved into the Win11 Sub-Forum (due to the specific Win11 problem) and thread title customized
@JuanLUX : Welcome to the Win-RAID Forum! Please post the HardwareIDs of both Intel SATA Controllers (AHCI and RAID). You get them by doing a right-click onto them and then choosing the options "Properties" > "Details" > "Property" > "HardwareIDs". Maybe you will have to use an Intel RST RAID driver (and not an RSTe one). Enjoy the Forum and good luck! Dieter (alias Fernando
Thanks Fernando (Dieter) for the warm welcome and for moving the thread to the appropriate subforum, below you will find the PCI Vendor & Device IDs for either the RAID and the AHCI controllers:

In regards to your suggestion of using RST and not RSTe correct me if I’m wrong but with X99 chipset is only possible to use the RSTe as the classical drivers are not suitable for it. Am I missing anything?
@JuanLUX : lfb6 is right - the option for owners of an X99 chipset RAID system to use an Intel RST RAID driver instead of an RSTe one, depends on the mainboard manufacturer and the specific BIOS configuration. The big majority of X99 chipset mainboards have a split solution: The on-board SATA ports are supported by RST drivers, whereas the sSATA ports (mainly running only in AHCI mode) need RSTe drivers. I don’t know the exact reason why the upgrade from Win10 to Win11 failed in your case, but I suspect a mismatch between the Win11 in-box Intel RST RAID driver v188.8.131.525 and the Intel RSTe driver v184.108.40.2060, which is in-use while running Win10. Since the Intel RSTe RAID driver, which obviously caused the interruption of the OS upgrade, is dispensable for this procedure (your drive C is managed by the MS in-box AHCI driver), I recommend to do the following: 1. Make a backup of your current used drive C: (with the OS and the hidden boot partition). 2. Unplug the power cables from your 2 RAID1 array member disks. 3. Re-try to upgrade to Win11. 4. Once Win11 is up (inclusive all available Updates) and running fine, reconnect the power cables of the 2 RAID1 array member disks, power on your PC and report here what happens (in case of a BSOD unplug the RAID1 array members and power on the PC again). Good luck!
Yes, the iaStorA.sys error message indicates, that there is still an old v4 platform RSTe RAID driver named iaStorA.sys in the Windows “Driver” store. Since the Intel RAID EFI SataDriver of your BIOS is still v220.127.116.118 and doesn’t match at all the currently installed RSTe v7 platform RAID driver, it seems possible for me, that the Win11 Setup tried to install a v4 platform Intel RAID driver, but didn’t succeed. In this case there are 2 options: a) update the Intel EFI “RaidDriver” module of the BIOS (requires a BIOS mod and flashing such mod BIOS) or b) downgrade the Intel RSTe RAID storage driver to a v4 platform one.
v18.104.22.1688 was the latest official update that I found in Dell site either for the controller BIOS and for the drivers, and the error during Win11 upgrade was the same when both versions matched Not sure if there is a trustful Mod bios for my controller
I revert back to v22.214.171.1248 some days ago and it doesn’t solve the issue
As commented I’m awaiting for a new disk that I ordered just for doing more tests during weekend.
I’m thinking also on doing a fresh Win11 install NVME disk mounted on a PCIe adapter without any other disk attached to the system and after that connect the two RAID disks
You should never uninstall a storage driver, when you are going to update or replace it. Reason: The OS needs the information to be able to revert to the previously used properly working driver.
The mainboard manufacturers do not test and offer the latest available drivers for their old hardware. If you want to get the latest Intel RST/RSTe drivers and RAID modules, you should better look into this Forum.
