insyde的BIOS中

OperationRegion(BMOP,0x9E,0x0,0x100)
Field(BMOP,DWordAcc,NoLock,Preserve)
{
SOC,32,//StateofCharge
FCCP,32,//FullChargeCapacity
CHST,32,//ChargingStatus
RMCP,32,//RemainingCapacity
....
.....
VOLT,32,//BatteryVoltage
DSCP,32,//BatteryDesigncapacity
TVOL,32,//TargetVoltage//(FOR_DEBUG)
ILIM,32,//InputCurrentLimit//(FOR_DEBUG)
}
.....
Store(BCTV,\_SB.I2C5.BMDR.TVOL)
Store(BCIL,\_SB.I2C5.BMDR.ILIM)
OperationRegionField是怎么和寄存器映射起来的呢最近刚接触BIOS，谢谢大家

楼主要研读一下ACPI的spec哈，http://www.acpi.info/DOWNLOADS/ACPIspec50.pdf
具体到怎么映射到寄存器，要看你这个0x9E怎么定义的，这个是oem自己的定义要看具体映射到IO/PCI/MMIO...哪个地方
