Hello,

The initial reboot followed the installation of ZFS-only version 5/28 system 
reports error:

Attempting Boot From Hard Drive (C:)                                            
gptzfsboot: error 1 lba 32                                                      
gptzfsboot: error 1 lba 1                                                       
gptzfsboot: No ZFS pools located, can't boot

The same installation procedure on older ProLiant with Compaq Smart Array 5i
do not cause any problems.

The system has been installed based on FreeBSD 8.2-20110731-SNAP i386 802510.
The P410i Controller presents two units, and the disk da0 has been partitioned as follow:

gpart destroy -F /dev/da0
dd if=/dev/zero of=/dev/da0 bs=1024 count=10000
gpart create -s GPT /dev/da0
gpart add -b 32K -s 64K -t freebsd-boot -l disk0boot /dev/da0
gpart add -s  30G -t freebsd-zfs  -l disk0 /dev/da0
gpart add -s   4G -t freebsd-swap -l swap0 /dev/da0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 /dev/da0
gpart set -a bootme -i 1 /dev/da0

Early experimentation show the following footprint:
