How to Hackintosh with Opencore - Part3: Add firmware to boot USB

Firmware Drivers
These are the drivers used by OpenCore, for the majority of systems you only need 2 .efi drivers to get up and running:

Needed for seeing APFS volumes(ie. macOS).
Needed for seeing HFS volumes(ie. macOS Installers and Recovery partitions/images). Do not mix other HFS drivers
For legacy users:

Used for OpenCore picker on legacy systems running DuetPkg, not recommended and even harmful on UEFI(Ivy Bridge and newer)
Used for Haswell and older when no NVMe driver is built into the firmware, not needed if you're not using an NVMe drive
Used for Sandy Bridge and older when no XHCI driver is built into the firmware, not needed if you're not using a USB 3.0 expansion card
The legacy variant of HfsPlus, used for systems that lack RDRAND instruction support. This is generally seen on Sandy Bridge and older
For a full list of compatible drivers, see 11.2 Properties in the OpenCorePkg Docs. These files will go in your Drivers folder in your EFI
