I wonder what are the limitations of MBR (/boot/boot0)?
I have the OEM-formatted harddrive (160MB), on which I want to add
FreeBSD into the free space.
I created the FreeBSD partition, set MBR (in 8.0-RC2), but when it
displays the boot prompt and I hit some key I only see '#' character
printed and nothing happens.
When I took MBR from my older FreeBSD HD and placed it on that one, it
doesn't print '#' characters but also doesn't boot.
When I boot into the healthy system with this new OEM HD attached I also
see dmesg messages like this:
GEOM: ad4: partition 2 does not start on a track boundary.
What could be wrong, why it doesn't boot?
