Here is the problem: I have written an interrupt handler for the clock interrupt that basically checks to see if a task that requires lower priority should run. So, what I would like to do is lower the priority of the current interrupt to a lower level. I tried doing this by changing the mask register in the 8259A, but this didn't seem to do the trick. I think the problem is that I am doing a non-specific end of interrupt rather than a specific end of interrupt, or that somethng else must be changed besides just the mask regsiter... Any ideas (of working pieces of code)? Thanks in advance, -- Matt
