Folks,
I need some help on doing a memory upgrade on an e420. I was wondering if anyone has any good links I can look at prior to attempting this upgrade. On this e420, we are upgrading from 2 to 4 gigs.
Sun Enterprise 420R (2 X UltraSPARC-II 450MHz)
socket U0301 has a 256MB DIMM
socket U0302 has a 256MB DIMM
socket U1301 has a 256MB DIMM
socket U1302 has a 256MB DIMM
socket U0401 has a 256MB DIMM
socket U0402 has a 256MB DIMM
socket U1401 has a 256MB DIMM
socket U1402 has a 256MB DIMM
empty sockets: U0303 U0304 U1303 U1304 U0403 U0404 U1403 U1404
total memory = 2048MB (2GB)
WARNING: Layout of memory sockets not completely recognized on this system.
The memory configuration displayed is a guess which may be incorrect.
The 2GB of memory installed may be 8 256MB DIMMs populating any 2 of
the 4 banks, or 16 128MB DIMMs populating all 4 banks.
This is a known bug due to Sun's 'prtconf' and 'prtdiag' commands not
providing enough detail for the memory layout of this
SunOS 5.8 SUNW,Ultra-80 system to be determined.
This is not a bug in memconf, rather it is a bug in Sun's OBP.
A newer version of Open Boot PROM may improve this.
This system is using OBP 3.23.0 1999/06/30 13:53
