Delphi中获取BIOS信息的实现步骤

Delphi编程环境中获取BIOS信息,可以通过调用Windows API来实现。以下是主要步骤:

1. 引入API声明

首先,我们需要在Delphi项目中导入包含SystemInfo函数的kernel32.dll库,并声明函数原型。

uses Windows;
function GetSystemInfo(var lpSystemInfo: SYSTEM_INFO): BOOL; stdcall; external 'kernel32.dll' name '_GetSystemInfo@4';

2. 定义数据结构

接下来,定义SYSTEM_INFO结构体,用于存储从GetSystemInfo函数返回的系统信息。

type
  SYSTEM_INFO = record
    wProcessorArchitecture: Word;
    wReserved: Word;
    dwPageSize: DWORD;
    lpMinimumApplicationAddress: Pointer;
    lpMaximumApplicationAddress: Pointer;
    dpKernelBase: DWORD_PTR;
    dpUserBase: DWORD_PTR;
    dwActiveProcessorMask: DWORD_PTR;
    dwNumberOfProcessors: DWORD;
    dwProcessorType: DWORD;
    dwAllocationGranularity: DWORD;
    wProcessorLevel: Word;
    wProcessorRevision: Word;
  end;

3. 调用API并处理结果

创建SYSTEM_INFO结构实例,调用GetSystemInfo填充结构体,并输出信息。

var
  SysInfo: SYSTEM_INFO;
begin
  FillChar(SysInfo, SizeOf(SysInfo), 0);
  if GetSystemInfo(SysInfo) then
  begin
    // 显示BIOS信息
    ShowMessage('BIOS Version: ' + SysInfo.wProcessorRevision.ToString);
  end
  else
    ShowMessage('Failed to retrieve system information.');
end;

4. 其他扩展

可以调用其他API(如GetNativeSystemInfo),或读取注册表键来扩展并获取更详细的BIOS和硬件信息。
