    So tell me, I just finished brushing up on the IRQ bit in Myers book for the umpteenth time and I notice he's only got a little table to tell you what they are.

    How insane do you have be to memorizing IRQ's? Is the table in Myers book sufficient?

    Also it has to be said I've been trying to take the time to memorize CPU stats on the advice of Mr Myers in his book and I have to tell you its like banging my head off a wall.

    At the moment I'm trying to read them, then quickly covering them up and scribbling the stats down and repeating for several. Its sort of working but my head is done in!

    You need to know a bit about IRQs, but their importance has lessened in the latest version of the exams, as they become somewhat less relevant to PCs.

    In these days of Plug'n'Play it is usually the case that you never need to mess with IRQs, as many devices are now OK on sharing such a resource.

    But it is still useful to know the basic most popular ones.

    Review the official domains for the A+ exam. Anything listed there is fair game on the test, even if it isn't particularly relevant to today's PCs (you never know when you'll get a job working on legacy units). Good luck.

    UCM pointed me to this thread yesterday http://www.certforums.co.uk/forums/showpost.php?p=89855&postcount=5 it does seem to work.

    It isn't complete though as I think this post was done for 2003 objectives, you could look in your system information windows for the IRQs used on your system or in the computer management console, click on device manager, select view resource by type and you will get a list of all the IRQs being used on your PC.

    Are you allowed to take a blank piece of paper and a pen into these exams?

    I just wondered... some people may want to jot down a table that they memorised.
    So they can pick out a answer or work with it.

    They give you a board and pen when you go in so you can write notes.

    Do you need to learn all the IRQs other than COM and LPT for exam? (601-essentials)

    I suppose there are 3-4 other system devices, however, devices attached to PCI etc are likely to be auto-assigned and different in every PC.

    I never got any IRQ questions after all, but that does not mean you wont. The exams are different every time.
