Missing Drivers HP Small Form Factor dc7800

HP Small Form Factor dc7800
Microsoft Windows 8.1 (32-bit)

I have an HP Small form factor dc7800 desktop.  It was runninng Windows XP Pro.  I upgraded it to Windows 8.1 Pro.  Everything seems to work fine.  But there are two missing drivers in the list that I CANNOT find.  Looked for hours.  Not sure if I need them but these are the missing ones:

 

1) PCI Serial Port PCI bus 0, device 3, function 3 (Code 28)

2) PCI Simple Communications Controller PCI bus 0, device 3, function 0 (Code 28)

 

I've tried the HP website and they have my model of computer but no drivers for windows 8.1.....that I could find.  Any help, thanks.

Hi:

 

You need these drivers for those devices...

 

PCI Serial Port:

 

This package contains the Intel Local Management Service (LMS) and Serial-over-LAN (SOL) support for Intel Active Management Technology (AMT) for the supported desktop models and operating systems. This software is part of the Intel Digital Office Initiative.

Hi!,  @Lee38:

 

IMHO, if HP don't have driver's of Windows 8.1 Pro, if installed any is under your risk.

 

See the information of Microsoft for (Error Code28) ... https://support.microsoft.com/en-us/kb/310123#28

 

Code 28

The drivers for this device are not installed. (Code 28)

Recommended resolution

Install the driver

In the device's Properties dialog box, click the Driver tab, and then click Update Driver to start the Hardware Update Wizard. Follow the instructions to install the driver.

Note You may be prompted to provide the path of the driver. Windows may have the driver built-in. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor's website.


You're Welcome !.
Best wishes and regards.

Hi, @Lee38 :

 

I have a dc7800 running W10 Pro and those drivers I posted above will work just fine for you.

 

No risk at all.

Thank  you.  I've tried this website, there are no drivers for wdws 8.1.  I've tried the windows 7 drivers and they don't work.  Appreciate your help.

Hi:

 

Those drivers do work.  I used them myself as I posted on my dc7800.

 

If the auto install method doesn't work use the manual install method as follows...

 

This is for the serial port.  Then you can do the same thing for the simple comms controller.

 

Go to the device manager and click on the PCI seral port needing the driver.

 

Click on the driver tab.  Click on Update Driver.

 

Select the Browse my computer for driver software option, and browse to the driver folder that was created when you ran the file.

 

That folder will be located in C:\SWSetup\sp46134.  Make sure the include subfolders box is checked and the driver should install.

Missing Drivers HP Small Form Factor dc7800

Thank you.  I found both of these in my search but am having no luck.  They do download to the dowloads folder.  When clicked on they seem to do something bringin up a DOS windows and then disappearing.  But when trying to do a manual install, I can browse my computer for the driver, and it will not locate it anywhere.  I've installed manual drivers before but the machine seems unable to locate it.  I've gone to C:, users, downloads but there is nothing there and I can see it in the downloads list.  I'll keep pluggin away.  Thanks for your help/

Yes, that is where I got them from.  The drivers are good for 32 or 64 bit.

 

Sometimes you have to manually install them if the auto install doesn't work.

 

I do it all the time.
