I quote your message cause I can't seem to find it on the fbsd-Q list
and I like this problem solved too. Sure you can use an alternate
bootloader like grup, but I don't want to if not needed. It must be
possible to have fbsd on de 2th harddisk and to let the winXP loader
handle the booting of fbsd. All I need is some kind of "copy of the mbr"
(as I understand) to put this as a file on C:\FBSD.WHATEVER and put it
in the XP-loader.

Does anybody out there has some answers on this?
-(please)-
