PCI serial port driver issues on Windows 10 - HP Z1 workstation

[TapsaKoo]

I have similar PCI Serial Port driver issue on Z1 workstation (WM432EA#ABS) than described in  solution https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/PCI-driver-issue/td-p/6809698

Here are the Z1 PCI Serial Port device details from device manager;

PCI\VEN_8086&DEV_1C3D&SUBSYS_3561103C&REV_04

PCI\VEN_8086&DEV_1C3D&SUBSYS_3561103C

PCI\VEN_8086&DEV_1C3D&CC_070002

PCI\VEN_8086&DEV_1C3D&CC_0700

Does the softpaq sp69506.exe solution work also on the Z1 workstation?

Hi:

I would use the driver from your PC's support page...

This package contains the Intel Management Engine Software version 11.0 for the supported Workstation models and operating systems. This package installs the latest Management Engine Interface (MEI) and Serial-Over-LAN (SOL) drivers, as well as Intel Management and Security Status (IMSS), to support Intel Active Management Technology (AMT) versions 8.x and 9.x.

no, the softpack you reference is for  Windows 8, 7, Vista, XP

you need the "SOL" /"AMT" management driver you don't specify which Z1 model so i can only guess it's the entry model

HP Z1 Entry Tower G5

Hi, @DGroves 

He did specify what model he had by posting the product number.

The driver I gave him is the correct one right from the support page.

HP Z1 All-in-One Workstation Software and Driver Downloads | HP® Customer Support

It is for W10.

[DGroves]

ah,....the All In One (AIO) Z1 not the Z1 tower model which is indeed a different system............. so disregard my AMT tower link

the Intel Management Engine Firmware Update link is however applicable to his Z1 AIO model and should be applied

Operating systems:

Windows 10 (64-bit)

Release date:

Hi, @DGroves 

The file you gave him is to update the Intel Management Engine Interface.

The device that needs the driver is the Intel AMT device AKA 'PCI serial port'.

Super thanks! This one worked for me. Device manager is not anymore showing PCI Serial Port driver issue. Ports COM and LPT came visible.

You're very welcome.
