+    - Click the download link for "PREBOOT.EXE".\r
+    - Accept the Intel Software License Agreement that appears.\r
+    - Unzip "PREBOOT.EXE" into a separate directory (this works with the\r
+      "unzip" utility on platforms different from Windows as well).\r
+    - Copy the "APPS/EFI/EFIx64/E3522X2.EFI" driver binary to\r

+    - Intel have stopped distributing an IA32 driver binary (which used to\r
+      match the filename pattern "E35??E2.EFI"), thus this method will only\r

   - Include the driver in OVMF during the build:\r
-    - Add "-D E1000_ENABLE" to your build command,\r

     - For example: "build -D E1000_ENABLE".\r

   takes priority over other drivers that could possibly drive the card too:\r
