下面的程序是我几年前把一个CD播放器程序缩改成打开、关闭光驱的小程序，送给你玩玩吧。不过有个缺点，只能在纯DOS下运行，在Win9x的DOS窗口下运行时，如果光驱没有光盘是打不开的，但可以关闭。
#include<dos.h>
int ppp=0;
unsigned int cdnum;
char getbuff,setbuff;
char stop={0x0d,0,0x85,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
char setcd={0x1a,0,0x0c,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
char getcd={0x1a,0,0x03,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
main()
{int i; char ch;
_BX=0;
_AX=0x1500;
geninterrupt(0x2f);
if(ppp==0){cdnum=_CX;ppp=1;}
_AX=FP_OFF(getbuff);
_BX=FP_SEG(getbuff);
getcd=_AL;
getcd=_AH;
getcd=_BL;
getcd=_BH;
_AX=FP_OFF(setbuff);
_BX=FP_SEG(setbuff);
setcd=_AL;
setcd=_AH;
setcd=_BL;
setcd=_BH;
for(i=0;i<2;i++)
{
getcd=5;
getbuff=0x06;
_ES=FP_SEG(getcd);
_BX=FP_OFF(getcd);
_CX=cdnum;
_AX=0x1510;
geninterrupt(0x2f);
}
ch=getbuff&0x01;
if(ch==0)i=0;
else i=1;
if(i==0)
{_ES=FP_SEG(stop); /*Stop CD*/
_BX=FP_OFF(stop);
_CX=cdnum;
_AX=0x1510;
geninterrupt(0x2f);
setcd=1; /*Open CD*/
setbuff=0;
_ES=FP_SEG(setcd);
_BX=FP_OFF(setcd);
_CX=cdnum;
_AX=0x1510;
geninterrupt(0x2f);
}
else
{ /*Close CD*/
setcd=1;
setbuff=5;
_ES=FP_SEG(setcd);
_BX=FP_OFF(setcd);
_CX=cdnum;
_AX=0x1510;
geninterrupt(0x2f);
}
}

ftp://ftp.he.net/pub/marcj/cdrom.c 我试过了，可是好像有些问题，怎么光驱没有任何反应啊？既不打开也不关闭，更不会读盘！楼主的意思是要编个程序来打开和关闭光驱，而上面的经我改编的C程序很好用，把编译成的EXE改名为EJ.EXE，只要在DOS下按EJ回车，就可以打开光驱，在输入就关闭，我总喜欢用它。^_^
