Well, technically, this isn't what happens.

I installed Win7 first and FreeBSD after that. When I was finished, only 
Windows booted. The only way I could get FreeBSD to start, was to go 
into the setup of the motherboard (BIOS setup) and tell it to boot off 
another partition.

What I wanted was the computer automatically starting the boot manager 
and letting me choose whether I wanted Windows or FreeBSD. That however 
didn't happen.

This is a little redundant, but I really want to make this clear...

My motherboard is a Supermicro X10SAT. When the system starts, I can 
press F12 which lets me choose the boot device (basicly like in the BIOS 
setup, but an a temporary basis). This is a *motherboard* function, this 
is not a boot manager from any OS. The motherboard recognises both 
Windows (list item: "Windows boot manager") and FreeBSD (list item: "EFI 
OS").

I have seen no other boot manager after the installation nor did I see 
any chance to choose/configure/check one during the installation of 
FreeBSD. The handbook in rather silent about this subject too, which is 
quite a surprise to me. When I started out with Linux, everything was 
about being able to coexist with Windows on a single machine. I switched 
to FreeBSD a little later. My first FreeBSD CDs were of v3.3 (that was 
1999 and I am feeling very old right about now). The FreeBSD boot 
manager of back then wasn't as pretty as the one supplied with SuSE at 
the time but it did the same thing.

Is this an EFI thing or have the priorities shifted?

Best regards,
Chris
