"PXE OpROM Policy" and "Storage OpROM Policy" ???

[TECH J]

Hey,what the heck are "PXE OpROM Policy" and "Storage OpROM Policy" ? I have them in my bios of ascrock x470 master sli. I have CSM enabled for optimal compatibility,even though my drives are in gpt format and they work in uefi mode.

Both of these ("PXE OpROM Policy" and "Storage OpROM Policy") have a drop down menu, saying "Legacy only", "Uefi only"  and "do not lanch". What should i choose?I have dual boot windows 7 and 10.  Thanks!!

these let you run the bios rom from these devices. Uefi is for uefi boot, and legacy is for legacy boot mode.

 

If you don't need pxe boot and your system works don't touch it.

Can you explain me each one of them?And what to pick?Though,i want to be able to run properly my gtp os (not in legacy mode)and i want to install operating systems like win7.

these won't affect things like running windows 7(dont' do that anyways) and running other oses

 

pxe oprom lets you boot from the network, probably don't touch it.

 

if it works don't touch the storage one, but uefi might be needed, depends on the type of boot drive. This only affects pcie storage devices.
