| I have to admit that it's not very clear, but Table 2-6 of the Service
Manual lists eight tests and the sixth one is the FEPROM test (#6).
Unfortunately, the table doesn't list test numbers. Our goal has been
to call out the FRU in the displays. FRUs include CPUn, MEMnL, MEMnH,
and IODn. For the PCI motherboard (Saddle), we opted to give additional
information versus always calling out the PCI motherboard as the FRU.
Thus, Saddle FRUs include: FROM, COMBO, PCEB, ESC, NVRAM, TOY, and
I8242, among others. All of these reside on the PCI motherboard.
The goal is FRU callout for Field and component callout for MFG, so
this was our compromise solution.
SROM and XSROM perform power-up testing - detailed info about this
testing and callouts, etc. is provided in the Rawhide SROM/XSROM
Powerup Diagnostic Spec posted in note 38.2 of this conference.
SRM console then performs PCI bridge (Horse) and PCI motherboard
(Saddle) testing. These tests also report failure info to the OCP
display (a la SROM/XSROM). Test numbers start over at 1 in these
diagnostics; in retrospect, perhaps this was a poor decision. The
thinking at the time was that the display tells the user that I/O
tests will be performed and then proceeds to flash the various test
numbers, FRUs being tested, etc.
The only documentation available for the Horse/Saddle tests is that
provided in the Service manual, etc.
Hope this helps some.
