I’m trying to setup an Programmable Intervall Timer (PIT) on a x86 machine, but it doesn’t work anyway. I’ve registered an ISR at IRQ0, wrote timer control word to port 0x43, and wrote timer-value to 0x42.
Soo far, soo good.
My counter was counting and Interrupts happened, but not from my ‘source’ .
Perhaps someone have idea how to use this timers excatly.
Thanks a lot
