    Query about MultiProcessor Interrupt Control

    pandawei

      I have several question about interrupt control.

       

      1) The "Intel MultiProcessor Specification v1.4" is the most comprehensive and authoritative doc I found for multiprocessor interrupt control. But it looks too old. Does it still apply to the new Intel machine? or is there any other manual?

       

      2) In MP Spec v1.4, It's mentioned that An MP operating system is booted under either one of the two PC/AT-compatible modes. Later the operating system switches to Symmetric I/O Mode as it enters multiprocessor mode. Is it mandatory or recommended´╝č In other words, Is it workable that an MP operating system is booted under Symmetric I/O Mode?
