How about EOI of ADAM-4500?
Solution:
Programable Interrupt Controller (PIC) of ADAM-4500 is NOT compatible with 5059A or 8259 inside the standard PC, so the address of ADAM-4500 PIC port is not 20h. You can refer to "EXAMPLE4.C" in the ADAM-4500 diskette to find a special subroutine "EOI" and you will know the address of ADAM-4500 PIC port is 0xFF22h. This special subroutine is used to control the end of the interrupt.
