Sun T5120 Only show 4gb out of 32gb and disk 2 only???

Hello all, we just got a T5120 from our data center recycle team and I 
was installing Solaris 10 U10 BUT when I do a prtdiag it ONLY shows 4GB, 
when I do a prtconf, it shows 32GB??? All the memory modules are 
enabled.  Solaris 10 says it only has 4GB, when I boot it ONLY show 4 GB 
on the boot prompt. The WEIRD thing is that on the top right of the http 
ALOM, I see the Fujitsu logo as part of the banner???  I am also trying 
to figure out WHY I can only see disk drive 2, drive 0, drive one and 
three are no shows???  Any ideas please???

TIA...
