Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.
Hello Gurus,
I'm assuming DOS is not not aware of APIC. How is a timer ISR working
in DOS which would have setup the 8259 PIC and hooked its handler to IRQ0?

I don't understand your question. Please elaborate. Also, have you checked the Wiki?
IIRC DOS does not need any IRQs directly - the timer interrupt is still handled by the bios.
