You should read the threads here about kernel compilation, there are plenty. Basically, though you just do:
make xconfig (or menuconfig, to configure the kernel)
make dep (2.4 kernels only)
make modules_install (as root)
in your kernel source. Then you copy over the bzImage file, edit lilo.conf or grub.conmf (I think Mandrake uses GRUB, not LILO, by default), and reboot. But seriously, check out some of the many other threads about this.
