Hi, in the future I am planning a computer build that hopes to run upon a UEFI-install of 64-bit Windows 8.1. Looking into the specifications for Fast Boot and UEFI mode and all that jazz, it says I need UEFI Option Roms for my GPU as well as a UEFI motherboard. However I am confused as to... the actual requirements for UEFI only mode (or rather fast boot I guess... are they the same or associated?).

I currently use a D-Link PCI-e wireless adapter card on my computer due to a lack of internal network wiring between my room and the location of the router, so moving the router is out of the question as well (since its kept in someone's bedroom. It's a small house).

I plan to reuse this card for my next computer, however... GPUs require a UEFI-supporting OpROM to support CSM off mode... does CSM Off Mode (and by extension secure boot) prevent me from using my PCIe card cause I am not sure as to UEFI's effect on the wireless card...
