dos下取sata盘的型号与序列号问题，紧急求救

[kinbo]

各位老大，

小弟遇到一个头疼的问题，在dos下读取sata硬盘的型号和序列号，

在网上找了不少资料，但是大多都是针对IDE硬盘来的，对于sata硬盘，尤其是AHCI模式的sata硬盘视乎有点无能为力，

在此向各位求救了。

目前参考的源码如下：

#include<stdio.h>
#include<conio.h>
#include <stdlib.h>
#include<dos.h>

main()
{
unsigned char p[512];
unsigned int i;
unsigned int j=0;
unsigned int flag2;
unsigned int flag;

outportb(0x1f6,0xa0);
outportb(0x1f2,0x1);
outportb(0x1f3,1);
outportb(0x1f4,1);
outportb(0x1f5,1);

outportb(0x1f7,0xec);

do
{
flag=inportb(0x1f7);
printf("ide status is %d\n",flag);
}while(flag!=0x58);

for(i=0;i<256;i++)
{
flag2=inport(0x1f0);

p[j++]=(flag2<<8)>>8;
printf("%c",p[j]);
p[j++]=(flag2>>8);
printf("%c",p[j]);
}




printf("disk sn number=");

for(i=20;i<40;i++)
if(i%2==0)
printf("%c",p[i+1]);
else
printf("%c",p[i-1]);

printf("\n\ndisk model=");
for(i=54;i<94;i++)
if(i%2==0)
printf("%c",p[i+1]);
else
printf("%c",p[i-1]);

}

结果一直都是
IDE status is 81

望各位老大帮忙分析一下，是否这段代码对sata硬盘不适用？该怎么调试或者修改？

多谢两位高人啦，

俺是要在dos下实现，两位给的参考貌似都要在windows下跑，

另外，bios中关于硬盘参数的读取好像换是要用我那个代码的步骤，写3f7端口，但是为什么我的程序就通不过呢？

楼主为什么不换一种方式呢？机器的配置信息存放在BIOS里面，而Window好像把BIOS映射到物理内存了。我们可以从内存读取BIOS信息，这个应该可以知道的吧？

试一试下面的代码。下面的代码来自http://topic.csdn.net/u/20101203/03/c31adc34-f4ab-400c-9c35-e18f9538a218.html

这是我以前搜到的一个类，虽然自己不懂原理，但能用就行呵呵，VS2005环境测试绝对没问题，其他环境自己调试调试
