John,
As root, goto the /usr/src/linux directory. This should be a symlink to
/usr/src/linux-2.2.X-mdk where X is your kernel's teany version.
You've got three choices for the config.
make config is text mode and if you make a mistake you have to start over.
make menuconfig is text mode(curses library) which uses menu's, much nicer
make xconfig run only under X.
Use make menuconfig or xconfig
The section called 'Processor type and features' is where you choose the CPU
type. You'll want PPro/686MX. There are three other items:
1. Math emulation. don't need this for PPro
2. MTRR support. PII's have this and I believe PPro also. Use it.
3. SMP
It's best to go through all the menu items to make sure everything is set
correctly. All the distro's I've used have never had all the options set to
match the kernel they install. If you've got access to the Mandrake or RedHat
manual read the sections on kernel compilation.
The results of make config/menuconfig/xconfig are saved in the file .config
If you've got a copy of a good one with all the other options set you could
edit it directly and comment/uncomment the CPU options which should be near the
beginning of the file.
good luck.
