Not to worry.  A pdinfo (defined in vtoc.h) is a Physical Disk INFOrmation
block.  The driver is complaining that it can't find one, which is natural
if you haven't installed yet.  It appears inside of the UNIX fdisk partition
on V.3.2 systems, and in the first cylinder in V.3.0 systems.  It did say
WARNING, because this isn't necessarily an error.
