9.1-RC2 - could it be that the installer does not write the MBR?

I chose "entire disk", then deleted all partitions-suggestions except
the first one and created my own partitioning scheme.
(/, swap, var, usr, maybe /var/log and /home, too)

It had a version of Solaris. Maybe Opensolaris. I don't know exactly.
And I don't know if it had zfsroot or not. I created a HW-RAID1 with
the HP P400 controller on it.
The drives were previously used in another server.

I tried to install 9.1RC2 twice on these disks and it always went back
to the grub-prompt after reboot.
Then I installed 9.0 and it's running now.
