Dual Booting OpenBSD vs Windows7

[Mohammad BadieZadegan]

Hi,
I want to dual booting OpenBSD with Windows7 and read many more pages about
customizing windows *bcdedit* tools to booting dual OS like
*http://cromwell-intl.com/linux/multiboot-windows-openbsd/
<http://cromwell-intl.com/linux/multiboot-windows-openbsd/>*
*BUT*, all of these pages nothing changed and could not running dual OS.
Is that any hints about dual booting OpenBSD vs Windows7?
