>From the Winchip3 (which was the final winchip) specs.. "The IDT WinChip 3 processor also omits the software interface to the Intel-proprietary symmetric multiprocessing support: APIC. This bus function is omitted since the target market for the IDT WinChip 3 processor is typical desktop systems (which do not support APIC multiprocessing)." It didn't offer any alternative DIY-SMP either (or at least none that's documented). Centaur only became SMP capable with some of the C3 Nehemiah's a year or two back.
