# SMP OPTIONS:
#
# The apic device enables the use of the IO APIC for Symmetric I/O.
# The apic device enables the use of the I/O APIC for interrupt delivery.
# The apic device can be used in both UP and SMP kernels, but is required
# for SMP kernels. Thus, the apic device is not strictly an SMP option,
# but it is a prerequisite for SMP.
#
# Notes:
#
# An SMP kernel will ONLY run on an Intel MP spec. qualified motherboard.
# Be sure to disable 'cpu I386_CPU' for SMP kernels.
#
# Be sure to disable 'cpu I386_CPU' && 'cpu I486_CPU' for SMP kernels.
#
# Check the 'Rogue SMP hardware' section to see if additional options
# are required by your hardware.
# By default, mixed mode is used to route IRQ0 from the AT timer via
# the 8259A master PIC through the ExtINT pin on the first I/O APIC.
# This can be disabled via the NO_MIXED_MODE option. In that case,
# IRQ0 will be routed via an intpin on the first I/O APIC. Not all
# motherboards hook IRQ0 up to the first I/O APIC even though their
# MP table or MADT may claim to do so. That is why mixed mode is
# enabled by default.
#
# Mandatory:
device apic # I/O apic
#
# Rogue SMP hardware:
#
# Bridged PCI cards:
#
# The MP tables of most of the current generation MP motherboards
# do NOT properly support bridged PCI cards. To use one of these
# cards you should refer to ???
options NO_MIXED_MODE # Disable use of mixed mode
