| 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 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. |
