how to bpint

如何bpint windows2000下的Irq??

什么意思？断点中断？

是啊，softice的说明中只提到了98和nt的irq该怎么样通过interrupt mapping去拦截。

但是没有2000的说明？？

For Windows 95
Windows maps hardware interrupts, which by default map to vectors 8-Fh and 70h-77h, to higher numbers to prevent conflicts with software interrupts. The primary interrupt controller is mapped from vector 50h-57h. The secondary interrupt controller is mapped from vector 58h-5Fh.

Example: IRQ0 is INT50h and IRQ8 is INT58h.

For Windows NT
Windows NT maps hardware interrupts, which by default map to vectors 8-Fh and 70h-77h, to higher numbers to prevent conflicts with software interrupts. The primary interrupt controller is mapped from vector 30h-37h. The secondary interrupt controller is mapped from vector 38h-3Fh.

Example: IRQ0 is INT30h and IRQ8 is INT38h
 :( :(

里面“For Windows NT”的对于Win2k也适用的

那么，如果我的鼠标Irq是12，我应该bpint 42,是不是啊？？可是我试过不行，不知道为什么？？是不是我这样截有问题？？

不是啦，是bpint 3c (十六进制) :D

天哪，我一直以为irq是十六进制！！！谢谢，谢谢
