Bless seems to be pretty liberal about what it will bless.
I believe it looks for the presence of certain files on each volume. In the OS X case, I think it looks for /System/Library/CoreServices/SystemVersion.plist. For Windows, I think it looks for a WINDOWS folder and it might also check for the existence of an active MBR partition.
Anyway, you can use fs_usage to find out which files it looks at.
Kind regards,
Chris
