unsigned long s1,s2;
char sel;
sel='1';
CString MyCpuID,CPUID1,CPUID2;
__asm{
mov eax,01h
xor edx,edx
cpuid
mov s1,edx
mov s2,eax
}
CPUID1.Format("%08X%08X",s1,s2);
__asm{
mov eax,03h
xor ecx,ecx
xor edx,edx
cpuid
mov s1,edx
mov s2,ecx
}
CPUID2.Format("%08X%08X",s1,s2);

MyCpuID=CPUID1+CPUID2;//取得cpu序列号

硬盘物理序列号读取核心代码如下：
// Windows NT/2000/XP下读取IDE硬盘序列号
BOOL CGetHDSerial::WinNTReadIDEHDSerial(DWORD * buffer)
{
BYTE IdOutCmd [sizeof (SENDCMDOUTPARAMS) + IDENTIFY_BUFFER_SIZE - 1];
BOOL bFlag = FALSE;
int drive = 0;
char driveName [256];
HANDLE hPhysicalDriveIOCTL = 0;

sprintf (driveName, "\\\\.\\PhysicalDrive%d", drive);
// Windows NT/2000/XP下创建文件需要管理员权限
hPhysicalDriveIOCTL = CreateFile (driveName,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,
OPEN_EXISTING, 0, NULL);

if (hPhysicalDriveIOCTL != INVALID_HANDLE_VALUE)
{
GETVERSIONOUTPARAMS VersionParams;
DWORD cbBytesReturned = 0;

// 得到驱动器的IO控制器版本
memset ((void*) &VersionParams, 0, sizeof(VersionParams));
if(DeviceIoControl (hPhysicalDriveIOCTL, IOCTL_GET_VERSION,
NULL, 0, &VersionParams,
sizeof(VersionParams),
&cbBytesReturned, NULL) )
{
if (VersionParams.bIDEDeviceMap > 0)
{
BYTE bIDCmd = 0; // IDE或者ATAPI识别命令
SENDCMDINPARAMS scip;

// 如果驱动器是光驱，采用命令IDE_ATAPI_IDENTIFY， command,
// 否则采用命令IDE_ATA_IDENTIFY读取驱动器信息
bIDCmd = (VersionParams.bIDEDeviceMap >> drive & 0x10)?
IDE_ATAPI_IDENTIFY : IDE_ATA_IDENTIFY;

memset (&scip, 0, sizeof(scip));
memset (IdOutCmd, 0, sizeof(IdOutCmd));
// 获取驱动器信息
if (WinNTGetIDEHDInfo (hPhysicalDriveIOCTL,
&scip,
(PSENDCMDOUTPARAMS)&IdOutCmd,
(BYTE) bIDCmd,
(BYTE) drive,
&cbBytesReturned))
{
int m = 0;
USHORT *pIdSector = (USHORT *)
((PSENDCMDOUTPARAMS) IdOutCmd) -> bBuffer;

for (m = 0; m < 256; m++)
buffer[m] = pIdSector [m];
bFlag = TRUE; // 读取硬盘信息成功
}
}
}
CloseHandle (hPhysicalDriveIOCTL); // 关闭句柄
}
return bFlag;
}

// WindowsNT/2000/XP系统下读取SCSI硬盘序列号
BOOL CGetHDSerial::WinNTReadSCSIHDSerial (DWORD * buffer)
{
buffer[0]='\n';
int controller = 0;
HANDLE hScsiDriveIOCTL = 0;
char driveName [256];
sprintf (driveName, "\\\\.\\Scsi%d:", controller);
// Windows NT/2000/XP下任何权限都可以进行
hScsiDriveIOCTL = CreateFile (driveName,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,
OPEN_EXISTING, 0, NULL);

if (hScsiDriveIOCTL != INVALID_HANDLE_VALUE)
{
int drive = 0;
DWORD mmy;
for (drive = 0; drive < 2; drive++)
{
char buffer [sizeof (SRB_IO_CONTROL) + SENDIDLENGTH];
SRB_IO_CONTROL *p = (SRB_IO_CONTROL *) buffer;
SENDCMDINPARAMS *pin =
(SENDCMDINPARAMS *) (buffer + sizeof (SRB_IO_CONTROL));
// 准备参数
memset (buffer, 0, sizeof (buffer));
p -> HeaderLength = sizeof (SRB_IO_CONTROL);
p -> Timeout = 10000;
p -> Length = SENDIDLENGTH;
p -> ControlCode = IOCTL_SCSI_MINIPORT_IDENTIFY;
strncpy ((char *) p -> Signature, "SCSIDISK", 8);
pin -> irDriveRegs.bCommandReg = IDE_ATA_IDENTIFY;
pin -> bDriveNumber = drive;
// 得到SCSI硬盘信息
if (DeviceIoControl (hScsiDriveIOCTL, IOCTL_SCSI_MINIPORT,
buffer,
sizeof (SRB_IO_CONTROL) +
sizeof (SENDCMDINPARAMS) - 1,
buffer,
sizeof (SRB_IO_CONTROL) + SENDIDLENGTH,
&mmy, NULL))
{
SENDCMDOUTPARAMS *pOut =
(SENDCMDOUTPARAMS *) (buffer + sizeof (SRB_IO_CONTROL));
IDSECTOR *pId = (IDSECTOR *) (pOut -> bBuffer);
if (pId -> sModelNumber [0])
{
int n = 0;
USHORT *pIdSector = (USHORT *) pId;

for (n = 0; n < 256; n++)
buffer[n] =pIdSector [n];
return TRUE; // 读取成功
}
}
}
CloseHandle (hScsiDriveIOCTL); // 关闭句柄
}
return FALSE; // 读取失败
}

通过调用windows API函数就能获取硬件信息了。比如获取CPU信息可以通过GetSystemInfo来获得。具体的查下相关API吧。

windows api基本有详细的实例代码，可以参考下。
