It's chipset driver.
And Audio and USB work with windows drivers just fine, and the drivers that come from asrock website are just going to install some crapware that will eat your computer resources.
Are you sure? Have you ever watched Newegg's 3 part PC building tutorial? The video says you need chipset, LAN, USB, and audio drivers. I don't exactly know which ones those are listed on the site. If you could tell me which drivers are those four then that would help me.
EDIT: Nevermind, I will be able to figure out the rest. Thanks for telling me the INF is chipset though, I didn't know that.
