[2008-10-05 10:14] 课程设计２
以下是我在课程设计2中的总结：
功能(1):用db 0ebh, 0, 0, 0ffh, 0ffh,即jmp ffff:0，如果用汇编语言来写的话，就得用jmp dword ptr这样占用的内存单元太多了
功能(2):就是不能直接把c盘0面0道１扇复制到0:7c00h中,所以就得有个中间过渡
功能(3):我是用由下面的动态显示时间演化来的
assume cs:code
code segment
start: jmp short tstart
tdata db 9, 8, 7, 4, 2, 0
tdata2: db 'now time: yy/mm/dd hh:mm:ss','...
