请各位帮我看看这程式!!
请问错误的地方要如何修改??? 执行结果是什么???#include <dos.h>
void write_CMOS(unsigned char index, unsigned char data)
{
outportb(0x70, index);
outportb(0x71, data);
}
void main()
{
/* write data 0FF Hex to index 6C Hex of CMOS RAM*/
write_CMOS(0x6C, 0xff);
/* read data from index 6B Hex of CMOS RAM*/
outportb(0x70, 0x6B);
inportb(0x71);
}
