我xp3的注册表中没有这个注册表项

jxf268麻烦再看一下HKEY_LOCAL_MACHINE\System\ControlSet001\Services\Msahci项下的start值，谢谢。

在别人的提醒下找一个软件，CRYSTALDISKINFO，带源码：http://crystalmark.info/?lang=en

＝＝＝

atasmart.cpp文件内有各种磁盘接口类型的判断。

你需要下载源码，不是软件。

DWORD CAtaSmart::GetTransferMode(WORD w63, WORD w76, WORD w88, CString &current, CString &max, CString &type, INTERFACE_TYPE* interfaceType)
{
DWORD tm = TRANSFER_MODE_PIO;
current = max = _T("");
type = _T("Parallel ATA");
*interfaceType = INTERFACE_TYPE_PATA;

// Multiword DMA or PIO
if(w63 & 0x0700)
{
tm = TRANSFER_MODE_PIO_DMA;
current = max = _T("PIO / DMA");
}

// Ultara DMA Max Transfer Mode
   if(w88 & 0x0040){tm = TRANSFER_MODE_ULTRA_DMA_133; max = _T("Ultra DMA/133");}
else if(w88 & 0x0020){tm = TRANSFER_MODE_ULTRA_DMA_100; max = _T("Ultra DMA/100");}
else if(w88 & 0x0010){tm = TRANSFER_MODE_ULTRA_DMA_66;  max = _T("Ultra DMA/66");}
else if(w88 & 0x0008){tm = TRANSFER_MODE_ULTRA_DMA_44;  max = _T("Ultra DMA/44");}

else if(w88 & 0x0001){tm = TRANSFER_MODE_ULTRA_DMA_16;  max = _T("Ultra DMA/16");}

// Ultara DMA Current Transfer Mode
   if(w88 & 0x4000){current = _T("Ultra DMA/133");}
