Hello.
I have recently obtained an old ICL machine (from around 1991/1992). It
has CPU boards with multiple processor slots. The processors installed are
486DX/50 (2 of them), and the machine only has EISA bus (no PCI).
I have tried to look up information regarding similar machines and Linux
SMP, but I have been unable to find anything that looks too relevant. The
information I DID find, seems to imply that PCI bus is required for SMP
compliance. Is this the case?
Is there a way that multi-processor support can be "fudged" together on
this machine? I have tried hacking about with the smp.c file, but all I
have managed to do over the last week was make every new kernel I compiled
crash anc panic.
At boot-up, the machine says that no SMP compliant motherboard has been
detected, and is says it will use the dummy emulation APIC. It also says
that it only foudn one CPU, CPU0.
Is there anything that can be done to make this machine run with multiple
processors activated?
I have been told that the machine used to run multi-processor under NT,
but I haven't tried it, because I would rather run Linux.
This is probably not a good place to ask this question, but is the SMP
support in FreeBSD any different to that in Linux (i.e. would I have more
chance of getting ti to work under FreeBSD than Linux)?
Thanks.
Gordan
