The processor may be configured to monitor or to ignore two of its error inputs that are used to signal errors during FSB transactions. Those two inputs are:
MCERR# (Machine Check Error). Sampling A9# low at the trailing-edge of reset configures the processor to monitor MCERR#, while sampling it high configures the processor to ignore MCERR#. This is referred to as the processor's MCERR# observation policy. A detailed discussion of MCERR# may be found in the MCERR# entry in Table 55-1 on page 1314, in “The Request Phase Parity” on page 1204, in “The Response Phase Parity” on page 1268, and in “Data Bus Parity” on page 1270.
BINIT# (Bus Initialization). Sampling A10# low at the trailing-edge of reset configures the processor to monitor BINIT#. Sampling A10# high configures the processor to ignore BINIT#. This is referred to as the processor's BINIT# observation policy. A detailed discussion of BINIT# may be found in the BINIT# entry of Table 55-1 on page 1314.
