[net.unix] Multiple Memory Controllers for 4.x?

elias@eosp1.UUCP (Doug Elias) (04/02/84)

*
Rumor has it that 4.2 can handle multiple memory-controllers,
but that 4.1 can't...if this is the case, can someone explain
how things like interleaving and increase of main-memory past
an initial "upper-bound" are handled?

Please reply by email unless you feel it's of netwide interest...

Thanks,
doug

I think dispelling this is of general interest:
Both 4.1BSD and 4.2BSD handled the old 16K-chip memory controllers
properly, whether you had one or several of them.  Neither version of
UNIX will report errors properly on the newer 64K-chip version of
the memory controller, but the fixes aren't all that difficult.
