+- If you use USBToolBox to create a USB port map, be wary of the following:
+    - USBToolBox will create a kext that refers to specific **pcidebug** addresses, which are a combination of `Bus:Device:Function` such as `0:18:0`
+    - These addresses may change if Thunderbolt is enabled or disabled, so it's necessary to remember whether Thunderbolt was enabled or disabled when USBToolBox was used to generate the port map; the USB kext will work properly only when Thunderbolt is set to the same setting
+- On Asus X670E Gene and possibly other Asus AM5 boards, BIOS is already configured properly, but you may want to **enable** AMD EXPO or XMP for full memory speed and **disable** USB4/Thunderbolt
+- On other boards, check and set the following:
+    - EXPO or XMP for memory speed
+    - XHCI Handoff should be enabled
+    - Resizable BAR can be left enabled whether or not your GPU supports it
+    - Above 4G Decoding should be enabled
+- If your BIOS has option to disable iGPU, it is not necessary to do so; we can use the supplied SSDT-DISABLE-IGPU.aml to hide iGPU from macOS (it may be necessary to change the PCI path of iGPU inside the SSDT)
