  * OpenBM send version information of currently flashed program as a message over the ibus:
-   * openbm send: F0 len FF FB 01 12 rr rr rr rr chk (major version 8bit = 1:01, minor version 8bit = 18:12 -> 1.18, rr - reserved bytes)
+   * openbm send: F0 len FF FB 01 12 d3 d2 d1 d0 rr rr rr rr chk (major version 8bit = 1:01, minor version 8bit = 18:12 -> 1.18, d0-d3: device id as 32bit number, rr - reserved bytes)
 
  * now we have around one second time to send messages over ibus to set bootloader into "Firmware Update" mode:
    * send "Activate_Update_Mode" message incl. a password of up-to a variable length of up-to 128 bytes: FF 24 F0 FA FF pp pp pp ... pp chk (password is specific to every OpenBM unit)
  
- * if password was correct bootloader answer with: F0 05 FF FB hh ll ss chk, where hhll is a 16bit number representing the sum of all password bytes and ss is a size in bytes of maximal possible chunk size when programming (every chunk sent later must of this size except of the last chunk, which can have smaller size)
+ * if password was correct bootloader answer with: F0 05 FF FB hh ll chk, where hhll is a 16bit number representing the sum of all password bytes:
    * bootloader is activated and Yellow LED lights on
    * bootloader is deactivated if it not receive any firmware code chunks for the next 10 seconds (If boot loader is deactivated, Yellow LED turns off)
