 ## Boot up logo's are logos or animations shown on boot of IronOS

+These are programmed into the device just like the normal firmware.
 They can be (re)programmed as many times as desired after flashing the normal firmware.

 ### Data storage format
 
 The data is stored into the second last page of flash, this gives 1024 bytes of space for the entire payload of bootup logo data.
 
-The first byte is marked purely to
+The first byte is marked purely to indicate that the page is programmed and which revision of the boot logo logic it is
+The next byte indicates the frame timing in milliseconds, or `0` to indicate only show first frame for whole bootloader duration (still image mode)
+Then the OLED buffer is cleared to black, then every frame is encoded as either:
+
+### Full frame updates
+
+`[0xFF][Full framebuffer of data]`
+
+### Delta frame update
+
+`[count of updates][[index,data][index,data][index,data][index,data]]`
+Where index is byte location into screen buffer, and data is the new byte to plonk down there
+This just overwrites individual bytes in the output buffer
