[SunHELP] E450 CPU change and OBP flash?

[Lara Matthews]

Hi

Just to add my 2 peneth worth, you know that there are 3 different
mother board versions of the E450 A25-AA, A25-BA and A25-CA.  You need
to be up to a BA to support the 400MHz cpus and you need the CA mother
board to support the 480MHz.
