I've got a DECstation 5000 model 200 (currently running ULTRIX 4.2A) whose
primary (boot) disk, rz0, is a 300MB disk originally supplied by DEC with the
workstation.  The workstation also has two 1 GB disks which happen to be
IMPRIMISes.  I would like to make one of the IMPRIMIS disks be the primary
disk, since each release of ULTRIX gets bigger and bigger, and it no longer
fits on my 300MB disk.  

One of the IMPRIMIS disks died recently, and I just received a replacement
for it.  I partitioned it today using newfs.  I partitioned the 'a' partition
(for /) so that it would contain bootstrap information, and I partitioned the 
'b' (for swap) and 'g' (for /usr) partitions with the -n option of newfs (no 
bootstrap program).  I gave newfs a disk-type of rz57 (there was no exact 
match in /etc/disktab) which it overrode for the 'b' and 'g' partitions.  
Afterwards, I was able to run fsck successfully on all three partitions.

I then tried to load 4.3 from my TK50.  When the install program got to the 
part where it wants to know which disk to load to, it showed all three of my 
disks as options.  I chose rz2, my newly partitioned disk.  The install 
program then balked, and said:

	Unable to obtain device geometry for rz2.
	This is not a supported system disk.

I don't set up new disks everyday, and I've exhausted the "Disk Maintenance" 
section of the "System and Network Management" volume.  Have I missed any step 
in initializing the new disk? Or does the primary disk have to be a DEC disk?
Any advice would really be appreciated.

Thanks.
