1903 Fails due to Intel RST

[Jerrywol]

i7 cpu Win 10 PC. 

1903 fails due to error message that Intel RST file iaStorA.sys is no up to date ver 15.2.0.1020 to old.

HP has no updated download for Intel RST new enough.

HP list the Envy AIO 155 1903 compatible.

My IDE ATA/ATAPI controller did update to Intel RST 17.5.1.1021 via the Intel update download but DID NOT update the iaStorA.sys file? and did update a file iaStorAC.sys file to 17.5.1.1021 (see attached).

Could the iaStorA.sys files be deleted? 

Is the cause Intel RST not compatible with the new M.2 PCIe NVMe 256GB SSD from Samsung (MZVPW256HEGL-000H1) ?

Greetings,

Welcome to the forum.

I am not a HP employee.

I would try uninstalling IRST in Control Panel, Programs and Features.

You would then use Microsoft's AHCI Controller.

Try the 1903 update again.

I don't use Intel's SATA driver on my PC because I don't have any SATA drives. I only use M.2 PCIe NVME drives.

Thanks! that was fast.

I will give it a try.

I do have a Seagate 2T that is used for data only that is an SSD but not and M.2 PCIe NVME .

Would that be a problem ?

really appreciate the help, didn't know if I removed the RST stuff the Envy may not boot.

cheers,

Hi Jerrywol,

You're very welcome.

You don't need Intel's SATA drivers.

Microsoft will install compatible drivers. I am running a standard AHCI controller now.

The SATA SSD and the 2TB HDD will work fine.

Hi Jerrywol,

Did you remove the Intel SATA drivers?

Did you install 1903 after removing the Intel drivers?

Uninstalled IRST did not fix it.

But your input here did; you gave me the right stuff to allow me to disable the iastora.sys files.

I actually then renamed the iastora.sys files to iastora.sys.old

For some reason uninstalling the IRST did not delete those files.

All is well 1903 in and working just fine.

Thanks for you help with understanding I didn't really need the IRST anyway, I had thought I needed it for the NVMe SSD.
