i found very interesting method that uses linux grub2 to install openbsd . that is written in http://yanmoo.blogspot.jp/2012/04/vpsopenbsd.html.
main poin is ------------------------------- grub> kopenbsd /bsd.rd grub>boot by this method , i install debian and then oppenbsd in rental server. now openbsd uses whole disk (no debian) and run gui of openbsd . it is very fun!
