Hi,
I have received a 4100 that was meant to be upgraded at a customers
site from a 300MHz CPU to a 466MHz CPU. The current output on the
operator panel is
P0 FAIL 04 FROM0
The output on the terminal is
SROM V1.1 on cpu0
Sctr 0 -XSROM code CHKSM fail cpu0
Sctr 2 -XSROM code CHKSM fail cpu0
only after replacing the backplane the output changed to
SROM V1.1 on cpu0
Sctr 0 -XSROM deadr PTTRN fail cpu0
Sctr 2 -XSROM deadr PTTRN fail cpu0
There are no further fault indications on any of the LED's.
It does not matter what type of CPU is installed the system hangs.
I was told that the firmware upgrade was performed as described in the
manual and when the power reset was performed that was it.
I have ordered a set of B3040, B3050, and a REV F3 power control
module.
Can someone explain what the console message part "FROM" means?
I suspect it to be Flash ROM, but I have not found a document where the
short code is explained.
Any ideas in what the cause could be otherwise are apreciated.
Thank's
Michael

Which backplane did you replace?
Am guessing from your note that you incorrectly replaced the system
motherboard rather than the PCI motherboard (Saddle). The system flash
ROM (FROM) lives on the Saddle.
Power-up OCP display failure codes are described in the AlphaServer
4100/4000 Service Manual - in the Control Panel chapter; Table 2-1.
They're also described in the AlphaServer 4100 Configuration and
Installation Guide in the "If Power-up Fails" section. I'm surprised
you found this information difficult to find. Did you actually look at
any of the documentation?
The table in the Service Manual says FROM0 is Flash ROM0 and tells the
reader that this part resides on the PCI motherboard.
If you swapped the PCI motherboard and not the system motherboard, then
the next likely suspect is the PCI Bridge card (aka the Horse module).
Let us know the results.

Hi,
after changing the system motherboard again the system runs. No matter
which of the other modules are used it works. So I know, that after the
power off which was needed to upgrade to the 466MHz CPU's the system
motherboard died. Also the first spare was effected in the same way.
I replaced the system motherboard and after checkout I upgraded the
firmware according to the documentation. Repowering the system several
times did not change anything, so I installed the 466MHz CPU's and it
worked as well. I have no idea what caused the initial problem.
Thank's
Michael
