long for

Dear friends,
I meet a question.
When I use class VIOPort to virtualize the port 0xf0,I successed,but when I virtualize the port 0x378(print port)debugview threw error infomations as below:
CHKPRT  
:
Failed to hook port(\'CHKPRT\' is my application\'s name.)
and to virtualize the port 0x60(keyboard port),the same error occured.Can you tell me the reason.Long for your answer.
thanks a lot.
