Greetings!
Using: FreeBSD 4.3-Stable
Kernal config name: DARKSIDE
I am attempting to recompile my kernel for Multiprocessor support.. I have
chosen the SMP and APIC_IO options in the new kernel configuration file I am
using, but when the CONFIG gets to the subsequent configuration options
which follow, I get an error message:
DARKSIDE:66: unknown option "NCPU"
Exit 1
This error appears for all the below listed options unless I COMMENT them
out and then the CONFIG completes. Can anyone advise why this is occurring?
I wish to specify two CPUs but if it is unnecessary I will go ahead and
recompile with the below options commmented out.
-----------
options NCPU=2 # number of CPUs
options NBUS=4 # number of busses
options NAPIC=1 # number of IO APICs
options NINTR=24 # number of INTs
-------------
