LOCAL BUS INTERFACE
Prior to its first instruction fetch, the 80386 makes no internal requests to the bus, and,
therefore,
will relinquish bus control if it receives a HOLD request (see Section 3.7 for a
complete description of
HOLD cycles).
Interrupt requests
(INTR
and
NMI)
are not recognized before the first instruction fetch.
