 ### Configuration - Enable network boot
 Network boot is not enabled by default in the bootloader. To enable it the bootloader configuration file must be edited.

+**NOTE:** The `/lib/firmware...` file listed in the code block below should not be copied directly, as it requires a date be maually used. There are several versions of the beta bootloader inside that directory, so make sure to select the most up-to-date version for your Raspberry Pi.

+    * Remove the dependency check for the vl805 utility. This is deprecated
+      and there is no 64-bit version. The file is still available in Github
+      for anyone who wants to continue using USE_FLASHROM or create their
+      own scripts.
+    * Add a stable firmware directory based on the latest beta release.
+      Stable should be interpreted as feature-freeze releases. In this
+      case the core network boot is stable enough for most scenarios
+      and this de-risks adding new more experimental features in the
+      beta folder.

 ## 2020-01-22 - vl805 00137ad
     * Set the default/critical vl805 version to be 00137ad. This has the 
       same power savings as 0137ab but with fixes for USB webcams.

 Before selecting a firmware release directory this script checks whether there
 is a board revision specific variant e.g. critical-c03111. If present then the
 board-revision specific version is used in preference.
