VMD driver: Intel RST VMD Managed Controller 09AB and Intel RST VMD Controller 467F.

And my question below:

Hello stanleyhsiao,

Hello stanleyhsiao, 

Thanks for your patience. As you may know, the Intel VMD hardware generates 'dummy' devices for multi-function devices when mapped, these functions may be visible to the Windows® operating system, this will cover these devices and make sure there are no Yellow bands in the Device Manager for the dummy values. 

The driver need will depend on the manufacturer of the computer, in this case, Asus recommends for some of their devices Intel RST VMD Controller 9A08 as per this link: https://www.asus.com/us/support/FAQ/1044458/

On the other hand, Intel recommends version 09AB, so you will need to check with Asus to make sure what is version recommended for your motherboard.

For the duplicated drivers in the device manager, this may be related to the number of drives or sometimes an error when installing the driver, I recommend using the Asus RST Driver (https://www.asus.com/tw/Motherboards-Components/Motherboards/CSM/Pro-B660M-C-D4-CSM/HelpDesk_Download/).

Dear Deivid: 

Thanks for your patient explanation, now I got it 09AB and  'dummy' devices for multi-function devices concept and what about 467F version? It's for AlderLake CPU or PCH driver on mother board? Like 9A08 for Tiger Lake(TGL) right? 

Those are my final questions, thanks.

Best regards,

Hello stanleyhsiao, 

Thanks for your response. In this case, for driver 467F, I recommend you check this with Asus to confirm if this driver is needed for your computer.

I cannot confirm if the driver 467F is meant for the CPU or motherboard since this driver could be from the motherboard manufacturer and they used customized driver versions from our generic drivers and Asus needs to confirm if this driver could have been meant for other of their motherboards or laptops.
