Default Which is the best boot manager for OpenBSD?

I wonder which is the best boot manager for BSD system, starting from OpenBSD.
I speak about active project.

They all suck imo. Personally I prefer to just flag the active partition in fdisk. For example on my netbook if I need to boot into windoze, it looks something like:

Code:
$ sudo fdisk -e sd0                                                                                  
Enter 'help' for information
fdisk: 1> p
Disk: sd0       geometry: 19457/255/63 [312581808 Sectors]
Offset: 0       Signature: 0xAA55

fdisk: 1> flag 1
Partition 1 marked active.

Your post contains zero info about your requirements. So its hard to know what is limiting and what is not.

That would be a mere observation how the boot managers have certain capabilities that can't be easily circumvented on other way. Nothing more, nothing less.
Personally, on in its simplicity, I found it very elegant and minimalist.
For that matter I would like to have a question about it, when you are on windows and you want change again on OpenBSD, do you use the fdisk from the Cd with OpenBSD (using the Shell) or fdisk from Windows?

My requirements is known if exist an open (and active - so don't dead project) boot manager solutions that work on every OS.
Should be a package present on BSD system.

Actually i made a research and on OpenBSD i found:
$ pkg_info -Q grub
grub-0.97p4
Is this grub legacy (grub 1) ?
I prefer avoid grub2 for some unresolved issue with linux.

Using EaseUS partition manager atm. Not really recommending it, but its "free" and it seems to work

Yes, aleunix, that is an older grub.

You MUST state your technical requirements. I know from your history that you have at least one GPT drive, but others reading this may not know. That limits your choices, since many of the multiboot tools are MBR only.

I haven't gdisk installed on my system (Ubuntu 10.04) so i don't think that i'm using GPT.
Anyway how i can check, from inside openbsd, if have I really a GPT drive?

OpenBSD does not support GPT. The fdisk(8) program can only tell you if you have or do not have an MBR.
