对于软盘的访问没有限制；对于硬盘则不行，关于这方面的资料实在太多；可以查看以前的帖子。大致在2000下的方法是打开文件C：或D：或PHYSICALDRIVE0（即DISK 80）来进行读写；当然也可以通过驱动Top

如果写个DOS程序在WIN2K下运行的话，可以用INT13H。但是写成WINDOWS程序就不行了。查一下DDK方面的资料吧。

进ring0,用V86模式用int13.
或者在ring0里用古老的未公开的函数：
Ke386CallBios(UCHAR Int, PKV86M_REGISTERS Regs);
Ki386RetToV86Mode(PKV86M_REGISTERS InRegs,
PKV86M_REGISTERS OutRegs);

其它的东西很多人讲过了，自己做吧。Top
