The original problem you had ("Fast Instruction Access MMU Miss") is 
some strange thing that happens if you had Solaris kernel running on 
the machine after last power-cycle.  Just turn the machine off and then 
on to solve it.  I've seen that on all Sparc boxes I had access to 
(mostly Ultra 1 and some Netra boxes).

For the second problem (after you power cycled machine), it's kinda 
strange.  Can you check that your cdrom is really on 
/pci at 1f,0/pci at 1,1/ide at d/cdrom at 0,0?  The above message could also happen 
if media was not in the drive (if working remotely, have somebody check 
if CD got ejected or something) or if the media is corrupted (try 
burning another CD).

The setting of auto-boot variable shouldn't have any impact on either 
problem you were experiencing (the only thing auto-boot controlls is if 
after poweron you'd go to "ok" prompt, or the machine will start to 
boot -- it's usefull mostly during installing or troubleshooting so you 
don't need to babysit machine and race to send break before it starts 
to boot).

See Ya' later, alligator!
