I GOT REALLY WORKED UP REMEMBERING DMA I/O'S AND IRQ BUT IN THE EXAM I HAD 1 QUESTION ON IRQ AND THE REST WERE TROUBLESHOOTING, MAINTANENCE, UPGRADING AND PRINTERS!!! FF YOU NEED TO REMEMBER THEM HERES THE ONES I SEE MOST OFTEN! BUT THE STRANGE THING IS THAT THEY CHANGE FOM SITE TO SITE OR BOOK FROM BOOK! TRY LOOKING AT THE DMA CHANNELS ON YOUR MACHINE!
