AMDA00 Fix for x99 boards - Unknown Device ACPI\PNP0A0A

[maddick]

So I ran into an issue I've seen posted about across the internet where the AMDA00 device (the temperature sensor) would not properly install but instead show up in the device manager as Unknown Device (hardware id ACPI\PNP0A0A
). I battled with my system for a bit then landed on a solution that worked twice (I ended up needing to re-install my OS). Here is the solution I found.

• Open the folder installed by the Asus driver package under Program Files on your system and locate the atkexComSvc.exe file. It was found under "Program Files\ASUS\AMDA\AXSP" on my system
  
  
• Double-click and execute atkecComSvc.exe or if you have UAC enabled, right-click it and select "Run as administrator".
  
• This should generate the file "PEbiosinterface32.dll" in that folder. I would wager this also starts a communication service on your machine.
  
  
• Now go into your device manager and right-click the unknown device and uninstall it.
  
• Restart your machine.
  
• Magic happens
  
  

This solution worked twice for me. I hope it works for others as well. I know how very irritating these issues can be.

They're not really correlated. Go ahead and do a normal restart. You should get the 219 error without the 6008 error.

You WILL see a 219 every time your system crashes and reboots (which is what the 6008 error is telling you happened), because you'll see 219 on every single reboot, crash or otherwise. Something is crashing your system, but it's not the 219 error. We all get the 219 error all the time.

Hi,
thanks fro your reply. I just run into this issue again and checked the event log. See attached screen shot. at 17:57:03 I have a Critical Event, id 41. The descritpion is in Italian and it says:
Re-start of the system without a regular shutdown. This error maybe caused by an interupption or an anomaly stop or unexpected
interruption of the electrical power.

One second later you can see the warning related to the 219 id. If the two are not related, how can I find out what is causing the 41 ? By reading all other previous event, everything appear to be OK.

Thanks

Hi Guys

Since this Monday, I have also a problem with the AMDA00 Driver. The system crashes and after a Reboot there is a yellow exclamation mark
on the AMDA00 interface in the device manager, with Code 37 (cannon find the object name). The only thing I can do, is a system restore.
When I try to delete the driver, the "delete window" appears but I cant delete it and I cannot close the window. I can close it when I kill the console with the task manager.
Same situation when I try to deactivate it. The other problem is now, that some services cannot start probably and I cannot restart the system, it get a blue screen after 5-10min after I pressed restart.

A friend of mine has the same board and dont have problems like me. He also has the same driver installed to that device. The only thing I realized, that Windows installed 2 new updates on Monday, but that were only some flash updates for Internet Explorer.


So far I know its the ASUS PC Sense Driver.

Any advice?

But no problems for now.

Hello all, I got both AMDA problem and WudfRd
It's ASUS B85M-G m/b + GeForce GT740 video card on Win 7 64bit

Initially, the above-mentioned Probe Sense II driver + manual activation of atKexComSvc =
HELPED and Unknown device transformed into 8 to 12 "sensors" and etc, after reboot
(and this ok status kept on being ok, great thanks to Mr. Maddick original post!)

However, later on I had to replace my video card (original one got cooler problem
and cooler was not replaceable), and just after switching from external video
to internal video , suddenly AMDA got "Unknown" again, and PC started to
get wonderfull "freeeeezes" during routine operations.

I thought motherboard went nuts ... luckily, this trouble ended (ooh)
when I switched to new external Ge Force card - PC started to work normally again,
but AMDA remained Unkown device

Still bunch of Thermal sensors are present in Device manager - system devices,
but situation is stable only if I keep this Unknown device = "Disabled".

If I enable it, it might or might not be recognized, but when it's Enabled =
with every iphone/digital camera USB connection - I got WudfRd error in System log.

If it's disabled - not WufdRd error - and that's why I keep it disabled.

P.S. Rumours are, the source of the problem is how drivers and utilities were installed -
which one first, second, third ... but I don't know the correct sequence - I got problems
initially after Win 7 installation - cause my PC doesn't have DVD-rom, and I had to install
MB info-update + network drivers first, before I touched anything else.

P.P.S. Of course I tried to remove all drivers - including AMDA, Probe Sense,
Nvidia Geforce drivers, and so on - any related, and then reboot and install
them again - but it didn't help at all.

What is uknown, seems to be remain unkown 🙂

This route also fixed the issue on my Sabertooth Z87. It was not causing any errors, and both AI Suite III & my Corair Link never had issues with displaying temperature. The Unknown Device just caught my eye while I was installing an add-on SATA card.
