The spec sheet at that URL doesn't even mention the fact that it's a
dual processor motherboard, and the picture links are broken today
so you can't confirm it visually. However, this motherboard uses
the Triton HX chipset, which only supports Intel-style PIC. Go look
at the HX chipset specs (for APIC vs. OpenPIC vs. somethingelsePIC
support), then go look at CPU specs... Like I said, Intel patented
(or something) their flavor of PIC and chose not to support the
other two flavors of PIC (which the AMD and Cyrix chips support)...
