Thus, the apic device is not strictly an SMP option, 31# but it is a prerequisite for SMP. 32# 33# Notes: 34# 35# Be sure to disable 'cpu I386_CPU' for SMP kernels. 36# 37# By default, mixed mode is used to route IRQ0 from the AT timer via 38# the 8259A master PIC through the ExtINT pin on the first I/O APIC. 39# This can be disabled via the NO_MIXED_MODE option. In that case, 40# IRQ0 will be routed via an intpin on the first I/O APIC. Not all 41# motherboards hook IRQ0 up to the first I/O APIC even though their 42# MP table or MADT may claim to do so. That is why mixed mode is 43# enabled by default. 44# | 23# Debug options 24options NPX_DEBUG # enable npx debugging (FPU/math emu) 25 #new math emulator |
