# SMP OPTIONS:

# The apic device enables the use of the I/O 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:
#
# Be sure to disable 'cpu I386_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,
