Well, the show goes on :-(
Today I tried again to bring up an older Siemens/Nixdorf PCE-5Smp
aka ALR Revolution Q-SMP.
Here waht I did:
first upgraded to the newest available BIOS (4.04.6) -> effect: mptable
can have a look on what's in the machine (failed before).
Machine has three CPU boards, P100 with each board's own Cache (MESI)
controler.
After BIOS update mptables exposes this output:
MPTable, version 2.0.15
looking for EBDA pointer @ 0x040e, found, searching EBDA @ 0x0009f000
MP FPS found in Extended BIOS Data Area @ physical addr: 0x0009f0a0

MP Config Table Header:

# SMP kernel config file options:
# Required:
options SMP # Symmetric MultiProcessor Kernel
options APIC_IO # Symmetric (APIC) I/O
# Optional (built-in defaults will work in most cases):
#options NCPU=3 # number of CPUs
#options NBUS=2 # number of busses
#options NAPIC=1 # number of IO APICs
#options NINTR=24 # number of INTs
===============================================================================
I applyed the suggested kernel config options, once with and once without the
optional, commented out options.
When booting the machine with SMP kernel, I get first the message:
Warning, using 2 out of 3 CPUs. It seems, that one CPU can notbe used, maybe due the
fact of the odd number of processors. But either 2 or 3 CPUs, it doesn't matter the effect is always
the same. After loading the kernel, I get the message about the available memory, then
some messages about programming APIC pin 0 on IRQ 16 or similar, then EISAINTCONTROL 0000c200.
After this message I get the message: AP# 1 (PHY# 1): failed. panic? (y/n):
When typing 'n' booting goes on up to a stage, when some IO devices, like SIO or parallel port,
should be initialized. Then the machine freezes.
I tried some othe combinations with the interrupts (16 instead of 24 as suggested by
mptabel), but I have not played yet with all possible combinations.
Well, I personally accuse the EISA configuration for this failure, but
I'm not an expert. Has anybody any idea or suggestion what to do? I would
appreciate any hint or tip, thanks!
===============================================================================
Kind regards
