how to setup irq with masm

Question

How can I setup IRQ using C++ and Masm, most of the search results refer me to Nasm, I am trying to create a bootloader of my own, I get it to boot from cd (iso) then I want to add menu options but cant seem to setup IRQ

An example that uses nasm can be found at Bran's Kernel Development looking something like

global irq0

; 32: IRQ0
irq0:
    cli
    push byte 0
    push byte 32
    jmp irq_common_stub

extern irq_handler

irq_common_stub:
    pusha
    push ds
    push es
    push fs
    push gs

    mov ax, 0x10
    mov ds, ax
    mov es, ax
    mov fs, ax
    mov gs, ax
    mov eax, esp

    push eax
    mov eax, irq_handler
    call eax
    pop eax

    pop gs
    pop fs
    pop es
    pop ds
    popa
    add esp, 8
    iret

Singularity is another sample I looked at...
