I have two DS10s, I will call them laurel and hardy.
I havea few LX164 and 164 boxes, a couple of 250 4/266 boxes,
some 3K boxes, and one lousely little little one that seems to have died.

My approach for building a new system is to take one of my boxes, one 
with a cdrom, and put a new drive in it and build from ISO image. QUick, 
easy, repeatavle.

I picked up a case of IBM 9GB scsi 3 drives. All work fine.  I use
them in a couple of boxes.  I took some of the drives, built them from
scratch as system bootable drives.  I did everything but the last bit of
rc.conf stuff on each drive.  I have gone thru 6 of them installing them 
and configuring, and running and using them.  I added one of these, 
blank drives, to a ds10 (laurel), built the bootable drive from cd. 
Booted it, works fine, configured the beast, and put it in operation.

I got my next DS10 (hardy), I popped it open, found the IDE CDRom was 
not cabled, put a new fresh drive in the OTHER DS10 (laurel) (the one 
that was and is running fine) followed the same process, and built a 1.6 
version bootable drive ffrom CD.  Moved the new drive to the new DS10 
(hardy). System started to boot, and then hung.  Took the drive, plugged 
it in Laurel, and the drive booted fine.

So, I have done a little trouble shooting by easteregging one known 
variable - the drive, and it checks good.

I took the drive from Laurel, popped it in hardy - again, making sure 
cables were rite, booted the beast, serila console, did the diag thing, 
did the show drives, only one drive showing, the new one, only one drive 
plugged into the trminated SCSI cable, the new drive. Booted.

Same deal - known good drive, fails to boot in system that is not known.
Flipped in the original drive that came with the box, booted it. A 
little RZ 1GB scsi3 or maybe 2GB.  Booted fine.

The IBM drives are larger storage, same physical, but higher current 
draw.  This is why I suspect power supply.
