Hey all quick question

So i have a Asus z790-e motherboard and in windows under device manager it says a i have a few errors about PCI device i know i can install intel serial I/O driver to fix this and get rid of the errors but is there an option in bios i can disable to also get rid of the errors instead of installing another driver kind of the the VMD error that also is on this motherboard simply fixed by disabling VMD in bios? 

I have no idea what serial i/o drivers are for other than it says with a quick google search that is controls I2C, UART, or GPIO. I have no idea what those are or if my system even needs them.

 

any help would be appreciated. Thanks

Hello, @Newasususer21 Ensure you have installed the Intel Chipset, Bluetooth and Thunderbolt driver from the support page.

Yea ive got those drivers but on this motherboard there are 4-5 pci device errors that are caused by the intel serial i/o driver not being installed and i just want to know if i need that driver or is there an option in bios i can disable to get rid of the errors instead?

Install this

Why would you want to disable anything rather than install the driver? It pertains to several devices, it's probably best to install it.

So what is it for? Do i need it? Or are you just telling me to download it for no reason?

The serial IO driver generally acts as an interconnect for communication between embedded controllers, even occasionally down to internal sensors/temperature sensors. The question is more why wouldn't you install it if using the motherboard given how small the file footprint is?

I only want to install necessary drivers and if theres an option in bios i can disable or enable to get rid of an error ill always chose that option.

If there is no option in bios to fix this serial io device manager problem i will just download the driver.

 

Thanks for the help I appreciate it. 

As i said in my first post there is also a vmd error in device manager but to get rid of it i have a few options 

1- install vmd driver wich i dont need because i have a nvme m.2 

2- install a intel rapid storage driver which i dont need because i have a nvme m.2 

or 3- which i can just disable vmd in bios and boom error is gone

i chose option 3
