Dual booting OpenBSD and Windows 8.1

[zalit]

Hi

I was thinking of dual booting OpenBSd and Windows 8.1. Has anyone 
managed to do that?
I suppose I would have to install Windows first, and then OpenBSD.
Does the OpenBSD installation include a boot manager such as GRUB?
I have experience setting up dual booting with GRUB, when installing 
Linux. Is it ok if I follow the same procedure with OpenBSD? If not, how 
would you advise me to go about it?

Thanks
