Delay question

[renovatio]

Hello, I want to delay a second, so i am using int 15h 86h to do it...

CX = Number of microseconds to wait (high byte)
DX = Number of microseconds to wait (low byte)

What is the value of CX and DX to delay a second?

Thanks in advance

This reeks of spoonfeeding answers.

What makes that you can not possibly answer this question yourself?

My god, can you not freaking count?

Google SI prefixes.

I tried working it out:

1 second = 1000000 microseconds

1000000 = F4240h

So CX = Fh And DX = 4240h

CX:DX = 000F4240h

But this is less than a second when i try it

Probably cause you're testing in bochs and the clock is running too fast, amirite?

I'm using Microsoft Virtual PC 2007

Works fine for me in VPC.

I just did this last night. See here: http://artofhacking.com/IET/PRGM/live/aoh_pit.htm

It's in pascal, but shouldn't be hard to translate to something else. The trick is to adjust the tick count each hit, for a second just count out ten hits and then pull the trigger.

But, that is PIT, for a delay you might try CMOS. Hope this helps.

thanks for your help, the code was ok, it doesn't work properly on virtual pc, but yes on real hardware

Are you talking to me? It works fine in VPC. That's what I use. You might be using the wrong values. Check the link and compare.
