Hello all.

I wanna ask a question about softice again. When i start softice, the windows
system is stopped. How is this possible? Softice doesn't hook irq0(timer),
i think. But, the windows system can't get the chance of handling a timer
interrupt.

I wanna use a same method like softice's to implement my little driver.
Any ideas?

thanks for reading.

SoftICE grabs the full control over the CPU by loading another descriptor
table addresses to it.
After this, it is Windows which runs on SoftICE, and not SoftICE on
Windows.

OTOH you do can play with timer if you are in the kernel mode or in Win9x in
the user mode. In Windows CE you have timer.c source for programming TIC so
you can change interval from default 1 msec.
