In case anyone here was curious, I have an ancient neptune EISA/PCI dual
pentium motherboard that works great under SMP...
Enclosed are the dmesg and mptables, if anyone's keeping a database. I think
it's safe to conclude that if this board works, anything will. :)
Dual P/100's (the fastest this board will support without modification),
40Mb of RAM. Primary IDE is PCI(mode 3), secondary is ISA(mode 0).
This board also has the 'clock drift' problem that my Tomcat IVD does when
running a SMP kernel. (clock randomly speeds up and slows down. never going
slower than realtime, but frequently going double)
