+*This mini carrier board was developed alongside the LattePanda Mu Ultra compute module (based on the Intel Lunar Lake processor). The carrier board is code-named Lunar Lake IO Board, or LIO for short, which is the origin of the "LIO" suffix in the BIOS name.*
+
+**These BIOS firmwares enable the LattePanda Mu N100 / N305 compute module to be compatible with the DFR1293 Mini Carrier Board.**
+
+💡**Note:** The LattePanda Mu compute module is available in 8GB and 16GB memory versions. It is essential to select the correct BIOS firmware as described below.
