Hi,

I have a question. I was wondering what driver a would a hard drive be using when running over a PCIE interface at the bios? Is it still using a standard NVME driver? IRST? I am new to the world of PCIE based hard drives and was curious as what, if anything was worth updating module wise on my ROG Maximus IX Hero with the latest run of UBU on my bios.

Thanks,

J

PCI-e device uses ".dxe" files integrated into UEFI.
Standard/Legacy BIOS doesn't support PCI-e based M.2 devices at all (ie. they aren't bootable).

Drivers you think about are used only in Windows or other OS.
They are irrelevant/redundant from BIOS/UEFI point of view.
