• Note(!): IRQ 11 can’t be used by peripherals connected to the ISA BUS if the printed
circuit board code ends with the letter “S” (PC100112S). If the printed circuit board
code ends with the letter “A” (PC100112S), there aren’t any problems.
• Note: not all consecutive IRQ numbers from 3 to 15 can be used; to help the selection, the
Setup program displays legal IRQ numbers only.
• Note: if the IRQ is shared, all the ports using the same share number can use the same IRQ
number .
