8400 cpu Upgrade

Hi,

I have just added another duel 625 CPU to our 8400. It now has 10 CPU's. I
followed the same procedure as I did when upgrading to 8 CPU's except I had
to downgrade the CPU firmware rev level to 5.1-30 from the supplied 5.2-7. 
The information with the CPU stated that the CPU should not be downgraded
below 5.1-30 so it should have been OK.  I was restricted by system
downtime and was told to downgrade the new duel CPU card and not upgrade
the 8 CPU's currently in the system.

I am getting a message that I have not seen before.  Looking at the
startup, everything passes the test and the INIT starts. At the end of the
init sequence after the device confirmations I get 

FLASH FRRC, CPU 8 does not match CPU 0 
FLASH FRRC, CPU 9 does not match CPU 0 

Then the startup continues and the UNIX boot starts. 

I have formatted the eeproms and built the NVR.   I also moved the new card
back into slot TLSB slot 0 without the other CPU's in their slots to check
the environmantals are they are the same as the other CPU,s.

I have a feeling that the EV level has changed on the CPU's with concole
5.2-7 and this may be the cause.

The system is running ok and is seeing 10 CPU's but this message worries
me.  Can somebody help.  If I have to upgrade all of the other CPU,s I
will.

Regards, Colin.
