有DOS下搜索PCI设备的编程方法吗 - 中国DOS联盟论坛

采用ｐｃｉｂｉｏｓ中断。

直接对端口和寄存器编程
可以参考<>这本书

用汇编就可以的。

我写了一个程序，可以查找所有的PCI设备。

PCI BIOS的中断号是0X1A你可以用它，去访问所有的PCI DEVICE，不过你要知道DEVICE NUMBER，FUNCTION NUMBER，VERNDOR ID。你用一个FOR循环，把这些地址从0开始搜索就可以啦。

给一个可执行的文件啊

举一个例子（在Win98中执行）：
研华的PCI-1713是一块32通道的、PCI总线的AD卡，PCI总线卡的基地址是由操作系统分配的，在一台计算中，可以插入多块相同的PCI卡。故不同的计算机硬件配置会导致PCI卡基地址是不定的。我的系统插有两块相同的PCI-1713卡。为了获得PCI-1713的基地址，程序是这样的

//研华的PCI-1713的供应商代码
#define VENDOR_ADVANTECH 0x13FEL

//研华的PCI-1713卡的设备代码
#define DEVICE_ADVANTECH_PCI1713 0x1713L

//函数功能：扫描指定格式字的PCI卡，返回多个相同格式字PCI卡的基地址。
//入口参数：dwFormat ----低16位为供应商代码，高16位为设备代码
//出口参数：pnBase1 ------ 符合指定格式字的第一块PCI卡
//出口参数：pnBase2 ------ 符合指定格式字的第二块PCI卡
//返回值：找到为真，否则FALSE
BOOL ScanPCI_IO(DWORD dwFormat, int* pnBase1, int* pnBase2)
{
if (pnBase1 != NULL) *pnBase1 = NULL;
if (pnBase2 != NULL) *pnBase2 = NULL;

//i为总线号
for (char i = 0; i < 5; i++)
{
//j为设备号
for(char j=0; j < 32; j++)
{
DWORD dwPCI = 0x80000000Lu + i * 0x10000Lu + (j * 8) * 0x100Lu;

//第0个双字
DWORD dwPCI_Vendor = dwPCI | (0x0 * sizeof(DWORD));
::_outpd(0xcf8, dwPCI_Vendor);
DWORD dwDeviceAndVendor = ::_inpd(0xcfc);
//判断供应商代码和设备代码是否相同
if (dwDeviceAndVendor != dwFormat)
{
continue;
}

//分析每一个基地址
for (int k = 0; k < 6; k++)
{
DWORD dwPCI_Base = (dwPCI | ((4 + k) * sizeof(DWORD)));
::_outpd(0xcf8, dwPCI_Base);
DWORD dwBase = ::_inpd(0xcfc);

BOOL bMem = !(dwBase & 0x1);
dwBase &= 0xFFFFFFFEL;

//I/O，必须地址有效
if (!bMem && (dwBase != 0x0 && dwBase != 0xFFFFFFFEL))
{
if (pnBase1 != NULL && *pnBase1 == 0)
{
*pnBase1 = (int)dwBase;

if (pnBase2 == NULL)
{
return(TRUE);
}
}
else if (pnBase2 != NULL && *pnBase2 == 0)
{
*pnBase2 = (int)dwBase;
return(TRUE);
}

}

}

}
}

return(FALSE);
}

//获得研华PCI-1713的基地址。
//函数功能：扫描研华PCI-1713的基地址
//出口参数：pnBase1 ------ 第一块PCI-1713卡的基地址
//出口参数：pnBase2 ------ 第二块PCI-1713卡的基地址
//返回值：找到为真，否则FALSE

BOOL ScanAdvantech_PCI1713(int* pnBase1, int* pnBase2)
{
return(::ScanPCI_IO(((DEVICE_ADVANTECH_PCI1713
<< 16) | VENDOR_ADVANTECH), pnBase1, pnBase2));

}

这个程序在一些电脑上执行会出现许多重复的设备？能不能修正一下这个程序？

我刚才试过的一台电脑，有一个板载网卡（接口不通），另装有一个PCI网卡，都是8139的。

测试结果如下：

24 2 09 6 10EC:8139 Network Controller
25 2 09 7 10EC:8139 Network Controller

它里面多出了许多个网卡的项，而实际上只有两个网卡才对。
我又用了其它的测试工具进行测试，结果都没问题。所以我觉得应该是这个程序的问题了，因为这个编译之后只有1.5K，比起同类软件小了许多，所以强烈希望能修正这个程序问题。谢谢！

另附其它工具在同一台电脑上的测试结果：

1、用PCILIST.EXE 测试的结果是：

举一个例子（在Win98中执行）：研华的PCI-1713是一块32通道的、PCI总线的AD卡，PCI总线卡的基地址是由操作系统分配的，在一台计算中，可以插入多块相同的PCI卡。故不同的计算机硬件配置会导致PCI卡基地址是不定的。我的系统插有两块相同的PCI-1713卡。为了获得PCI-1713的基地址，程序是这样的 //研华的PCI-1713的供应商代码 #define VENDOR_ADVANTECH 0x13FEL //研华的PCI-1713卡的设备代码 #define DEVICE_ADVANTECH_PCI1713 0x1713L //函数功能：扫描指定格式字的PCI卡，返回多个相同格式字PCI卡的基地址。 //入口参数：dwFormat ----低16位为供应商代码，高16位为设备代码 //出口参数：pnBase1 ------ 符合指定格式字的第一块PCI卡 //出口参数：pnBase2 ------ 符合指定格式字的第二块PCI卡 //返回值：找到为真，否则FALSE BOOL ScanPCI_IO(DWORD dwFormat, int* pnBase1, int* pnBase2) { if (pnBase1 != NULL) pnBase1 = NULL; if (pnBase2 != NULL) pnBase2 = NULL; //i为总线号 for (char i = 0; i < 5; i++) { //j为设备号 for(char j=0; j < 32; j++) { DWORD dwPCI = 0x80000000Lu + i * 0x10000Lu + (j * 8) * 0x100Lu; //第0个双字 DWORD dwPCI_Vendor = dwPCI \| (0x0 * sizeof(DWORD)); ::_outpd(0xcf8, dwPCI_Vendor); DWORD dwDeviceAndVendor = ::_inpd(0xcfc); //判断供应商代码和设备代码是否相同 if (dwDeviceAndVendor != dwFormat) { continue; } //分析每一个基地址 for (int k = 0; k < 6; k++) { DWORD dwPCI_Base = (dwPCI \| ((4 + k) * sizeof(DWORD))); ::_outpd(0xcf8, dwPCI_Base); DWORD dwBase = ::_inpd(0xcfc); BOOL bMem = !(dwBase & 0x1); dwBase &= 0xFFFFFFFEL; //I/O，必须地址有效 if (!bMem && (dwBase != 0x0 && dwBase != 0xFFFFFFFEL)) { if (pnBase1 != NULL && pnBase1 == 0) { pnBase1 = (int)dwBase; if (pnBase2 == NULL) { return(TRUE); } } else if (pnBase2 != NULL && pnBase2 == 0) { pnBase2 = (int)dwBase; return(TRUE); } } } } } return(FALSE); } //获得研华PCI-1713的基地址。 //函数功能：扫描研华PCI-1713的基地址 //出口参数：pnBase1 ------ 第一块PCI-1713卡的基地址 //出口参数：pnBase2 ------ 第二块PCI-1713卡的基地址 //返回值：找到为真，否则FALSE BOOL ScanAdvantech_PCI1713(int* pnBase1, int* pnBase2) { return(::ScanPCI_IO(((DEVICE_ADVANTECH_PCI1713 << 16) \| VENDOR_ADVANTECH), pnBase1, pnBase2)); }
