Hello,

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 7.6.0.1020 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

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?

Thanks lfb6 and Fernando for your messages.

@lfb6 I confirm that I'm on latest BIOS version (A34) and also with OROM RSTe 4.6.0.1018 (see screenshots below)



Regarding BIOS options for the system are also very limited as you can see in the screenshot:




@Fernando:

I will follow your suggestion and during the weekend I will clone my boot drive with win10 and disconnect the RAID1 disks to perform the upgrade to Win11. I will report back the results.

Thanks again for you help and support.

Regards

Were those BSODs always iaStorA.sys? From RSTe 5.x it should be iaStorE.sys?

Did you clean up your installed drivers with pnputil before starting the upgrade process?

Do you have the possibility to try a fresh Win11 install on another harddisk, raid disks disconnected?

@lfb6 Sorry I explained incorrectly in my first post, yes wiith versions 3.x and 4.x it was iaStorA.sys the one giving the 0xC19000101, 0x20017 BSOD error

Starting with RSTe 5.x it was iaStorE.sys

I didn't perform any cleanup with pnputil, it was only when I switch the AHCI SATA controller to Windows standard when I uninstall the iaStorA.sys driver

Currently in the drivers directory I have the following iaStor?.* drivers with their versions:



I'm awaiting for a new disk to arrive on Friday to do a fresh Win11 install on it without the Raid disks

@Fernando

v4.6.0.1018 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 v4.6.0.1018 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

Is there any text for the BSOD error 0xC91......like 'unaccessible boot device' ot any other text? Could you post a picture of this BSOD?

If one searches for this error there's a lot of finds, doesn't seem to be very specific (and there's no specific solution either).

In addition to an earlier post: RST or RSTe mode isn't only the modules, it's chipset configuration, too. SATA controller changes device ID when configured as RST, RSTe, AHCI , see https://www.intel.com/content/dam/www/pu...h-datasheet.pdf

I wonder why you'd have 2 different drivers loading here. I have a C222 board with RSTe, and there's no SATA driver for my (of course) non-RAID CD drive?
