Issue Description: 

Sun Blade 1000/2000 systems may fail to boot from disk or may boot
as a Sun Fire 280R due to an Open Boot PROM (OBP) issue.

This issue is most prevalent in systems shipped during January 2003, 
but could occur in any Sun Blade 1000/2000 system with OBP version 
less than 4.5.21.  To determine a system's OBP version, run one of 
the following:

   .version  (from the OBP "ok" prompt)
   
   /usr/sbin/prtconf -V  (from a Solaris prompt)

When this issue occurs there are two possible scenarios:
    
   1. A Sun Blade 1000/2000 system tries to boot as a Sun Fire 280R 
      but fails to find the boot disk.  The following messages may 
      be displayed:
      
	"Could not read keyswitch position!"
	"Could not find boot device"
	"Could not read fan or power supply status"
	
      When the system tries to come up as a Sun Fire 280R, it will not
      see any disks because the physical address of the boot device is
      different for a Sun Fire 280R versus a Sun Blade 1000/2000.

   2. The Sun Blade 1000/2000 boots as a Sun Fire 280R.  This would 
      only happen when the system boots over the net.  This is not 
      desirable due to differing thermal parameters and software 
      operating environment.
  
A bug in the OBP firmware does not take into consideration a corner 
case for the BBC Scratch RAM where the OBP determines what kind of 
system the common Sun Blade 1000/2000/Sun Fire 280R System Board is 
installed in.

The bug is an OBP dependency on an uninitialized register value within 
the motherboard BBC chip. Recent batches of BBC chips have been coming 
in with a different uninitialized signature and results in a Sun Blade 
1000/2000 system being identified as a Sun Fire 280R.  Subsequent queries 
for a Sun Fire 280R system attributes such as a keyswitch and RSC card 
will then fail and the "disk" boot device cannot be recognized.

This issue has been addressed with the release of OBP firmware version 
4.5.21, made available in Manufacturing via ECO WO_26077.  This firmware 
version is available as patch 111292-12.

Implementation: 

---
        |   |   MANDATORY (Fully Proactive)
         ---    
         
  
         ---
        |   |   CONTROLLED PROACTIVE (per Sun Geo Plan) 
         --- 
         
                                
         ---
        | X |   REACTIVE (As Required)
         ---

Corrective Action: 

The following recommendation is provided as a guideline for authorized
Sun Services Field Representatives who may encounter the above
mentioned issue. 

Install OBP patch 112292-12 or later on Sun Blade 1000/2000 systems 
having OBP versions less than 4.5.21.  Please follow the special firmware
installation instructions provided with the patch README file. 

If a system will not boot to allow patch installation, run the following 
from the OBP "ok" prompt:

   ok setenv diag-switch? true
   ok reset
   
This permits the system to boot normally.

None

Implementation Footnote: 

i)   In case of MANDATORY FINs, Sun Services will attempt to contact   
     all affected customers to recommend implementation of the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Sun Services mission critical    
     support teams will recommend implementation of the FIN  (to their  
     respective accounts), at the convenience of the customer. 

iii) For REACTIVE FINs, Sun Services will implement the FIN as the   
     need arises.
