请帮忙看看这是什么原因，连接时出现提示信息是这样的 ！

Linker Error: Undefined symbol `_inpw`in module  HDS.C

谢谢了~！急死我了，知道上学的时候就不出去玩了~！

下边是原程序代码：

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

char *GetAscii(unsigned int inData[], int offStart, int offEnd);

int main(void)
{
   unsigned int   diskData[256];    /* Disk data                  */
   unsigned int   offset;           /* Disk data offset           */
   int            loop;
   int            numDrv;           /* Number of IDE hard drives  */
   union REGS     registers;
   unsigned int   biosCyl[2];       /* Cylinders, Heads, Sectors */
   unsigned int   biosHead[2];
   unsigned int   biosSec [2];

   numDrv = peekb(0x40, 0x75);      /* BIOS Data area, Number of Hard disks */
   for (loop = 0; loop < numDrv; loop++)
   {
      while (inp(0x01f7) != 0x50);  /* Wait for controller not busy         */
      outp(0x01f6, (loop == 0 ? 0xa0 : 0xb0));  /* Get first/second drive   */
      outp(0x01f7, 0xec);                       /* Get drive info data      */

      while (inp(0x1f7) != 0x58);   /* Wait for data ready                  */
      for (offset = 0; offset != 256; offset++) /* Read "sector"            */
         diskData[offset] = inpw(0x1f0);

      /* Get BIOS drive info */
      registers.h.ah = 0x08;        /* Get drive info                          */
      registers.h.dl = 0x80 + loop; /* Drive is 80H for Disk 0, 81H for Disk 1 */
      int86(0x13, &registers, &registers);
      if (!registers.x.cflag)       /* All OK if carry not set */
      {
         biosHead[loop] = registers.h.dh + 1;      /* Heads are from 0 */
         biosSec[loop]  = registers.h.cl & 0x3f;   /* sec is bits 5 - 0 */

         /* +1 because starts from 0 and +1 for FDISK leaving one out */
         biosCyl[loop]  = ((registers.h.cl & 0xc0) << 2) + registers.h.ch + 2;
      } /* end of if */

      printf("DRIVE %d:\n", loop);
      printf("Model Number______________________: %s\n", GetAscii(diskData, 27, 46));
      printf("Serial Number_____________________: %s\n", GetAscii(diskData, 10, 19));
      printf("Controller Revision Number________: %s\n\n", GetAscii(diskData, 23, 26));
      printf("Able to do Double Word Transfer___: %6s\n", (diskData[48] == 0 ? "No" : "Yes"));
      printf("Controller type___________________:   %04X\n", diskData[20]);
      printf("Controller buffer size (bytes)____: %6u\n", diskData[21] * 512);
      printf("Number of ECC bytes transferred___: %6u\n", diskData[22]);
      printf("Number of sectors per interrupt___: %6u\n\n", diskData[47]);
      printf("Hard Disk Reports\n");
      printf("Number of Cylinders (Fixed)_______: %6u\n", diskData[1]);
      printf("Number of Heads___________________: %6u\n", diskData[3]);
      printf("Number of Sectors per Track_______: %6u\n\n", diskData[6]);
      printf("BIOS Reports\n");
      printf("Number of Cylinders_______________: %6u\n", biosCyl[loop]);
      printf("Number of Heads___________________: %6u\n", biosHead[loop]);
      printf("Number of Sectors per Track_______: %6u\n\n", biosSec[loop]);

      
   } /* end of for */

   return 0;
} /* main() */

char *GetAscii(unsigned int inData[], int offStart, int offEnd)
{
   static char retVal[255];
   int         loop, loop1;

   for (loop = offStart, loop1 = 0; loop <= offEnd; loop++)
   {
      retVal[loop1++] = (char )(inData[loop] / 256);  /* Get High byte */
      retVal[loop1++] = (char )(inData[loop] % 256);  /* Get Low byte  */
   } /* end of for */

   retVal[loop1] = '\0';    /* Make sure it ends in a NULL character */

   return retVal;
} /* GetAscii() */

谢谢大家，问题以经解决了，此源码须用BORLAND C++ 6.0编译才能通过~！

好像是未定义inpw模块

HDS.C文件里查看一下是否定义了
