Hi people,
I'm attempting to get Linux to come up SMP on an old NCR 3450
server. This server has 8 Pentium 90 CPU's and runs the old MCA bus
architecture. The details I know so far are as follows....
* System - NCR 3450
* CPU - 8X90MHZ
* MEM - 1024MB
* NCR certified MP1.1/1.4 compliant
* NCR certified NT4.0 ( with vendor supplied "HAL" )
* System boots Linux using the Slackware ibmmca.s boot image ( which
is SMP aware )
* System reports " Jul 27 14:48:00 aardvark kernel: SMP motherboard
not detected. Using dummy APIC emulation."
I'm guessing that the kernel does a probe of the BIOS to get the SMP
information it requires. On some motherboards the BIOS needs to be set to
MP1.1/1.4 mode or Unixware or something like that. There is no option to
set anything like this in the 3450 as it was built to run NCR MP-RAS UNIX.
Under the vendor OS it sees all 8 CPU's with no problems, but not under
Linux.
So, is there anyone else out there that has Linux running on one of
these machines and managed to get SMP going ? I'm also guessing that it
could be possible to force the SMP probe to succeed and manually set up the
kernel with the required parameters, this may be more effort than it's worth
though. Any ideas here? By the way, I have checked the usual sites for SMP
and MCA Linux but have found nothing to help so far.
Regards,
Simon.
