I've got a SS10 that I want to upgrade to SMP.  Both CPUs are
SM41s.  Individually they operate just fine, but when both are installed,
the machine won't even initialize.  The jumper settings are in "mode
a" according to the SS10 service manual.  Any ideas as to why it won't
operate with both CPUs installed?  The motherboard is the 3 jumper style.

Thanks!
