Hi,

That's mean i must install DOS on my PC. Can i use windows startup
disk booting up, to make an environment as dos? Is that still same as
dos box in win9x?

And if the new_timer(void) routine is too much coding, it can't finish
the job when the next interrupt came expected. Do i need to set some
interrupt masking flags?

How do i check the timing spent of this interrupt service routine?

Jeff
