Battery parameters
The BIOS will download all battery parameters to the smart charger before POST. The
battery parameters are as follows:
LI-ION CHG V (0x39) : Li-ion CV = (0x39) /3 *4
LI-ION DESINH V (0x3A) : ERROR = (0X3A) * 1.27 +2.3V
LI-ION EDVI (0x3B) : EDVI = (0x3B) /3 *4
LI-ION EDVF (0x3C) : EDVI = (0x3C) /3 *4
