Hi:

I have an Asus M32Cd, which was working fine.  However, like many others, I was plagued with Win 10 enforced updates messing up my system (e.g., removing printer drivers, not being able to rename folders, etc).  Eventually, after my 5th System Restore, I decided to downgrade to Win 8.1, where everything works fine, except some drivers are flagged under Other Devices.  Checked Windows Update, Asus support.  No luck. 

 

How do I find drivers for each of these devices:

 

Network Controller:

PCI\VEN_10EC&DEV_8821&SUBSYS_24821B9A&REV_00
PCI\VEN_10EC&DEV_8821&SUBSYS_24821B9A
PCI\VEN_10EC&DEV_8821&CC_028000
PCI\VEN_10EC&DEV_8821&CC_0280

 

PCI Memory Controller:

PCI\VEN_8086&DEV_A121&SUBSYS_86941043&REV_31
PCI\VEN_8086&DEV_A121&SUBSYS_86941043
PCI\VEN_8086&DEV_A121&CC_058000
PCI\VEN_8086&DEV_A121&CC_0580

 

PCI Simple Communications Controller:
PCI\VEN_8086&DEV_A13A&SUBSYS_00000000&REV_31
PCI\VEN_8086&DEV_A13A&SUBSYS_00000000
PCI\VEN_8086&DEV_A13A&REV_31
PCI\VEN_8086&DEV_A13A
PCI\VEN_8086&DEV_A13A&CC_078000
PCI\VEN_8086&DEV_A13A&CC_0780

SM Bus Controller:PCI\VEN_8086&DEV_A123&SUBSYS_86941043&REV_31
PCI\VEN_8086&DEV_A123&SUBSYS_86941043
PCI\VEN_8086&DEV_A123&CC_0C0500
PCI\VEN_8086&DEV_A123&CC_0C05

Thanks.

For your network controller go here. Click on the hard drive icon, not the green download button. Provide a junk email address. I am not sure this driver will work but it does have the same vendor and device ID according to driveridentifier which I have used before.  This is a Realtek 8821AE AC chipset and is not available on Realtek's site for some reason.

 

If this gives you internet then go here and download intel's utility to get your other drivers. The other drivers are intel as the Vendor ID is 8086.

Hi JohnC_21:

 

Thank you so much for your prompt reply.  I did what you had suggested re the internet driver, and it worked!!!!  I now have internet.

 

I followed your next  suggestion re getting Intel drivers by downloading the Driver Update Utility from the link you provided, and ran it.  Unfortunately, it says "No drivers were detected for your product".  Any help or guidance would be appreciated.

 

Thanks, again.

As I previously posted click on the small hard drive icon and provide a junk email address. These may or may not work for you. I would also create a restore point before installing these drivers and preferably do a complete disk image using something like Macrium Free.

The SM Bus Controller should be taken care of by the Memory Controller.

 Have you checked the Asus site for drivers?  Usually the manufacturer's web site is the first place you should look for drivers.

 

 Good luck.


Make regular full system backups or you'll be sorry sooner or later.

Only BIOS updates listed for 8.1. It may be possible to use drivers from a different M32 model with an intel MB but hopefully the above drivers I linked to will work.

Niweg:  Thanks.  I did check on Asus as well as Windows Update, but, what JohnC_21 says is accurate.  I don't know how he manages to find these drivers, as my searches have not revealed anything!!  In any case, I am very grateful to him for his help.

 

JohnC_21, I had used System Restore before installing the Realtek driver (System Restore has become my best friend since running into Win 10 Update problems!!!), but I hadn't done a complete disk image.  Thanks for the suggestion.  I'll do that before attempting these other two drivers.

 

Thanks, again

Yes!  No more "Other Devices"!  Everything seems to have worked, although, to be honest, the only one that I know worked was the Realtek wifi driver, as I don't know what the other drivers did.

 

Thank you very much JohnC_21.  I will now make a contribution to this site because of your help, which was both accurate, and prompt!

Glad you got everything sorted out. For your info you can look up the vendor and device IDs at pcidatabase.com. Also by doing a google search on the vendor and device ID it will usually lead you to driveridentifier.com which is a very good site for drivers if not available on the OEM website. Thank you for contributing to BC's defense fund.

JohnC_21:  I saw several driver sites online, but, quite honestly, I was concerned about using any of them because I was not sure whether they would load other stuff onto my computer.  I've copied your last post, and saved it, and will use it in the future.
