PC:BIOS与UEFI设置

了解BIOS与UEFI

BIOS的基本概念

BIOS, 即基本输入/输出系统(Basic Input/Output System),是早期计算机系统中用于初始化硬件并加载操作系统的固件程序。BIOS在计算机启动时运行,提供了一系列的设置选项,允许用户配置硬件参数,如日期和时间、启动顺序、硬盘设置等。BIOS的设置通常通过一个文本界面进行,用户可以通过键盘进行操作。

BIOS的主要功能
  • 硬件初始化:BIOS在系统启动时检测和初始化硬件设备,如CPU、内存、硬盘等。
  • 加载操作系统:BIOS负责加载操作系统到内存中,使计算机能够运行操作系统。
  • POST(加电自检):BIOS执行POST程序,检查硬件是否正常工作。
  • 设置选项:BIOS提供了一个设置界面,用户可以在这里更改系统配置。

笔记本的风扇控制 ---------------------------------------- 09 November 2006. Summary of changes for version 20061109: 1) ACPI CA Core Subsystem: Optimized the Load ASL operator in the case where the source operand is an operation region. Simply map the operation region memory, instead of performing a bytewise read. (Region must be of type SystemMemory, see below.) Fixed the Load ASL operator for the case where the source operand is a region field. A buffer object is also allowed as the source operand. BZ 480 Fixed a problem where the Load ASL operator allowed the source operand to be an operation region of any type. It is now restricted to regions of type SystemMemory, as per the ACPI specification. BZ 481 Additional cleanup and optimizations for the new Table Manager code. AcpiEnable will now fail if all of the required ACPI tables are not loaded (FADT, FACS, DSDT). BZ 477 Added #pragma pack(8/4) to acobject.h to ensure that the structures in this header are always compiled as aligned. The ACPI_OPERAND_OBJECT has been manually optimized to be aligned and will not work if it is byte-packed. Example Code and Data Size: These are the sizes for the OS- independent acpica.lib produced by the Microsoft Visual C++ 6.0 32- bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size. Previous Release: Non-Debug Version: 78.1K Code, 17.1K Data, 95.2K Total Debug Version: 155.4K Code, 63.1K Data, 218.5K Total Current Release: Non-Debug Version: 77.9K Code, 17.0K Data, 94.9K Total Debug Version: 155.2K Code, 63.1K Data, 218.3K Total 2) iASL Compiler/Disassembler and Tools: Fixed a problem where the presence of the _OSI predefined control method within complex expressions could cause an internal compiler error. AcpiExec: Implemented full region support for multiple address spaces. SpaceId is now part of the REGION object. BZ 429 ---------------------------------------- 11 Oc
