I wrote the following application, and it uses the function _bios_disk that is defined in the bios.h file. I imported the file, but I get the following error message during compilation: " diskread02.obj(diskread02) Error 42: Symbol Undefined _bios_disk --- errorlevel 1 " This has been a repeating problem for me so ANY help would be appreciated. #include <bios.h> #include <stdio.h> #include <stdlib.h> void main () { // declarations: int i; int result; static char dbuf[512]; struct diskinfo_t { int drive; // drive number for c: int head; int track; int sector; int nsectors; void* buffer; }; struct diskinfo_t diskinfo; diskinfo.drive = 2; diskinfo.head = 0; diskinfo.track = 0; diskinfo.sector = 1; diskinfo.nsectors = 1; diskinfo.buffer = dbuf; // operations: printf ("attempting to read from drive c:\n"); result = _bios_disk (2, &diskinfo); if ((result & 0xff00) == 0) { printf ("disk read from c: successful.\n"); } else { printf ("disk read operation failed. \n"); } for (i = 0; i <= 512; i ++) { printf ("0x%02x ", dbuf[i]); } }
