 ===SD Card Configuration===
-A standard SD Card (either from the BATC Shop or built using these instructions [https://github.com/BritishAmateurTelevisionClub/portsdown-buster Portsdown GitHub]) can be used in LimeNET Micros without eMMC flash.  On first-ever start-up it will reboot automatically twice before becoming operational.  On the first start-up, it detects that it is connected to a LimeNET Micro and substitutes the correct Device Tree file for using the 7 inch screen.  It then reboots to load this file, which enables it to detect the 7 inch screen.  Having detected the screen, it changes the config file to use the 7 inch screen and then reboots to load this new configuration.
+A standard SD Card (either from the BATC Shop or built using these instructions [https://github.com/BritishAmateurTelevisionClub/portsdown-buster Portsdown GitHub]) can be used in the pre-production LimeNET Micros without eMMC flash.  On first-ever start-up it will reboot automatically twice before becoming operational.  On the first start-up, it detects that it is connected to a LimeNET Micro and substitutes the correct Device Tree file for using the 7 inch screen.  It then reboots to load this file, which enables it to detect the 7 inch screen.  Having detected the screen, it changes the config file to use the 7 inch screen and then reboots to load this new configuration.
 If the same SD Card is then taken back to a standard RPi 3 based Portsdown, it will detect that it is not in a LimeNET Micro, substitute the original device tree file and then reboot to load it.  It then detects that there is no 7 inch screen, changes the config file for the Waveshare screen and reboots to load it.

 During the software update process, the device tree file is normally over-written.  If the update detects that it is being performed on a LimeNET Micro it then reloads the file required for the LimeNET Micro.
-Draft instructions for loading Raspbian Buster and the Portsdown software on a LimeNET Micro with eMMC flash (without an SD card slot) are at the bottom of this page.

-The Lime Report and Firmware Update do work with the Portsdown Stretch software.  These need the latest version of LimeSuite, which I have not yet integrated because it needs testing with the LimeSDR Mini first and I have run out of time.
+The Lime Report and Firmware Update do work with the Portsdown Stretch software.  These need the latest version of LimeSuite, which is only available in the Portsdown Buster software.
 With Portsdown Buster software, the Lime Report does work, but will erroneously report an error (in red) because it is configured to check the firmware version for a LimeSDR Mini, not a LimeNET Micro.  The LimeNET Micro firmware can be updated using the "Update Lime Micro" button,  DO NOT use the other update buttons.
