Issue Description: 
The Vcore setting for UltraSPARC IV 1350MHz boards is supposed to be
1.25V, but some earlier releases of firmware will power on and operate
the board at an incorrect voltage.

The release documents for UltraSPARC IV 1350MHz boards will correctly
state that the minimum firmware required is 5.17.4, 5.18.1, or higher.
Though it is unsupported, prior releases of 5.17 and 5.18 will allow
the CPU's to be configured, but the CPUs will be running at the wrong
voltage.

SMS 1.4.1 patch 117866-03 first introduced the capability of powering
on UltraSPARC IV 1350MHz boards with the inclusion of the fix for RFE
4968663.  However, as outlined in RFE 6191562, 1.25 volts is the
necessary Vcore setting.  Patch 117866-04 which includes RFE 6191562 is
the minimum supported patch level for running UltraSPARC IV 1350MHz
CPU boards on High-end platforms.

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

Treat any field failure as normal. If the failure mode seen usually
merits system board replacement, replace the board and inform the customer 
of the minimum firmware requirements.  Do not just simply upgrade the firmware.

Replace the board that experienced the failure and upgrade the firmware.
