参照MINIX3写的操作系统 用GCC+NASM+BOCHS开发

#include "include/RAM.h"

PUBLIC void ReadRAM(int DevPosition,int DestPosition,int Size)
//读RAM盘，DevPosition RAM盘的位置， DestPosition 目标数据的位置，Size 数据大小
{
	 MemoryCopy((void*)DestPosition, (void*)DevPosition,Size);
	
}

PUBLIC void WriteRAM(int DevPosition,int SrcPosition,int Size)
//写RAM盘，，DevPosition RAM盘的位置， SrcPosition 源数据的位置，Size 数据大小
{
	 MemoryCopy((void*)DevPosition, (void*)SrcPosition,Size);
}


/*void RAMTask()
//RAM任务循环

    int  DevPosition,DestPosition,SrcPosition, Size;
	 while(1)
