This is the part of an hooked int
            cmp CS:[MultiIdent],AH
            je short Do_it
            DB 0EAh             ; FAR JUMP into old INT 2Fh (chained)
Old_int2Fh: dw 0000,0000
Do_it:      sti                 ; Enable interrupts
Some text files said to enable interrupts inside the interrupt. I know some 
interrupt can be long enough especially int 21h and can slowing down things.
I need to know how the computer executes tasks in memory with resident 
programs. Someone can pictured this here?
