Hi guys.

I created Raid 1 with RaidFrame on two SATA drives by first installing NetBSD on one of them, 
creating raid on the other with fake device, booting off the second drive, syncing both the drives
and again installing MBR on the first drive - wd0 following this HowTo:
http://users.piuha.net/martti/comp/raid/raid.html
Now the MBR says at boot:
Boot failed (errno 2): Can't open /boot.

Any idea what may be wrong and how to fix it ?

Cheers,
Marcin.
