VirtualBox works incorrectly

[BiT-H@cK]

Good day. I've got some problems while developing software on VirtualBox. A driver which works perfectly on a real machine fails to work on virtual machine. The problem seems to be in that driver can't hook needed interrupts. At first open file with Open file button, when enter 01012475 at the OEP edit box and press Full unpack. If the program runs, something is wrong. Could you solve this problem? http://qunpack.ahteam.org/wp-content/up ... pack21.zip UPX packed file: http://rapidshare.com/files/122640865/calc.exe.html
