Sorry, I missunderstand your last email.

I've changed the procedure... and same problem at reboot.

Here is the new procedure:

/bin/dd if=/dev/zero of=/dev/ad0 bs=1k count=20
/sbin/fdisk -I -b /boot/mbr ad0
/bin/dd if=/dev/zero of=/dev/ad0s1 bs=32k count=16
/sbin/bsdlabel -w ad0s1 auto

the raid.conf file:
drive disk_ad1 device /dev/ad1s1a
drive disk_ad2 device /dev/ad2s1a
drive disk_ad3 device /dev/ad3s1a
volume raid5
plex org raid5 256k
sd length 102M drive disk_ad1
sd length 102M drive disk_ad2
sd length 102M drive disk_ad3
