OSPM通过将ACPI_ENABLE值写入SMI_CMD来执行此转换,SMI_CMD向硬件生成一个事件,以将平台转换为ACPI模式。当硬件完成转换时,它设置SCI_EN位并将控制返回给OSPM。当在G0“工作状态”时,OSPM可以通过将ACPI_DISABLE值写入SMI_CMD寄存器请求转换到Legacy模式,这将导致硬件进入Legacy模式并将SCI_EN位重置为LOW(更多信息,请...
•仅在ACPI模式下启动(不支持ACPI Enable, ACPI Disable, SMI_CMD和Legacy模式) •OSPM不能与其他异步运行环境(如UEFIRuntime服务、系统管理模式)共享硬件资源。(不支持全局锁) •不依赖操作系统的支持来维持跨处理器休眠状态的缓存一致性(不支持总线主加载和仲裁禁用) •不支持gpe块设备 不满足上述要求的系...
如果检测到当前槽位状态已经处于BLINKINGON/OFF state, 说明此时需要取消上次的热插或热拔操作,将槽位的状态恢复成ON/OFF state. b、当为Power Fault事件。 将power_fault_detected标志先置为1,表示电源异常不会重复处理,打开Attention指示灯,并将电源指示灯熄灭。 c、当为disable slot事件 DISABLE_SLOT主要用于响应...
You can also use MiniTool ShadowMaker to restore your system to an earlier state when the ACPI error didn’t occur. (Similarly, this is only useful when you have backed up system using it in advance.) How to back up system to local drive: Step 1: find download the installation program ...

After boot, the HFSP register may not reflect the true state of the EC (on some models it reads 0x07 even though the EC is actually in automatic mode). The HFSP register controls both fans at the same time in the X61/X61s.
