Djgpp 里无法调用中断 int13 ah=48h 苦恼～！

//#define _BORLAND_DOS_REGS

struct SREGS sregs;

struct{

DWORD cylns;
DWORD heads;
DWORD sects;
DWORD tslow;
DWORD tshi;
WORD bps;
}package;

regs.h.ah=0x48;
regs.h.dl=0x80;

//--- TC ---// TC用下面这两行传入段地址和偏移量就没有问题
//sregs.ds = FP_SEG(&package);
//regs.x.si = FP_OFF(&package);

//--- DJGPP ---// 可在DJGPP里我就不知道怎么输入这个量了~！
sregs.ds = _my_ds();
regs.x.si = _my_ds();

printf("ds=%x si=%x \n",sregs.ds,regs.x.si);

printf("package= %x \n",&package);

int386x(0x13,&regs,&regs,&sregs);
printf("%d \n",regs.h.ah);

printf("cyliners = %ld\n",package.cylns);
printf("heads = %ld \n",package.heads);
printf("sect/cyln = %ld \n",package.sects);
printf("Lsectors = %ld\n",package.tslow);
printf("Hsectors = %ld\n",package.tshi);
printf("bytes = %ld\n",package.bps);
printf("gb = %.f GB\n",(double)(package.tslow*512.0/pow(10,9)));
printf("-------------------------- \n \n \n");

}


高手显身吧~！快救救我~！

BIOS issue

楼上的兄弟，能不能给一个明白的答案呀？（请不要吐水哎～！）谢谢～！

try __dpmi_int

不知道是不是我笨, __dpmi_int(0x13,&r);

我怎么把sreg放进去呢????

参数结构都不一样...

麻烦你看清楚我的问题!

#include <sys/nearptr.h>
#include <crt0.h>

void * MK_FP (unsigned short seg, unsigned short ofs)
{
if ( !(_crt0_startup_flags & _CRT0_FLAG_NEARPTR) )
if (!__djgpp_nearptr_enable ())
return (void *)0;
return (void *) (seg*16 + ofs + __djgpp_conventional_base);
}
