box while the alternate disk is in another shoe box. Both are on the same
controller. I am running SUN OS 4.0.3. on both. I can get the alternate
disk to boot under Sun Os, but only with boot options that don't make sense 
and were figured out by process of elimination (one of my favorite methods).
By the way, if you have experienced trying to boot from an alternate disk
on a Sun workstation, please let me know. 


With 4.0.3 on the first disk (first on the controller) and Mach Os on the
second disk, second disk on same controller, I will then have the choice of
booting from either disk and therefore a choice of operating systems.
Doesn't that sound like fun? Well, I am not getting very far on this
and if you will excuse my ignorance, I will attempt to tell you my 
troubles. If you can help me and your information could be useful
to others, please post, otherwise you could just send me email.

  The instructions indicate that I should first copy to the system disk,
the utilities (mkfs is supposed to be the most important). I noticed a
file "stand/diag" which I didn't have as part of version 4.0.3. The
instructions say to boot from this file and format the disk, the partitioning
scheme is different (this is in disktab) . My problem- the system
boots from stand/diag alright but it doesn't see the second disk (says
it's not available. It sees the first disk but if you elect to verify,
it says the label is misplaced. However, when I select the second disk
then verify it, it says "Bad format". So strange. 

 In conclusion, I would think that I should see both of the disks with
the stand/diag I got from the distribution and the messages should make
sense. They don't. Why?

Again, I don't know much about Mach Os, so be gentle.
