+To set up SMP
+
+Configure the kernel and answer Y to CONFIG_SMP.
+
+If you are using LILO, it is handy to have both SMP and non-SMP
+kernel images on hand. Edit /etc/lilo.conf to create an entry
+for another kernel image called "linux-smp" or something.
+
+The next time you compile the kernel, when running a SMP kernel,
+edit linux/Makefile and change "MAKE=make" to "MAKE=make -jN"
+(where N = number of CPU + 1, or if you have tons of memory/swap
+ you can just use "-j" without a number). Feel free to experiment
+with this one.
+
+Of course you should time how long each build takes :-)
+Example:
+ make config
+ time -v sh -c 'make dep ; make clean install modules modules_install'
+
+If you are using some Compaq MP compliant machines you will need to set
+the operating system in the BIOS settings to "Unixware" - don't ask me
+why Compaqs don't work otherwise.
