first, you probably should consider upgrading to a newer version of Mandrake. 10.0 Official is the latest free version, 10.1 Official should be available to the public any day now. better/newer apps, more hardware support, 2.6 series kernel.
anywho, to answer your question, to install the kernel-source, do it one of 2 ways.........
first, to make sure you know what kernel version you're currently running, open a terminal as root & type........
that will list your current kernel & some other system info. note the kernel version number. now, to install the source.......
GUI method......... open Mandrake Control Center (type mcc in terminal as root->hit enter) then go to software management->install software. type kernel in the search box, check the kernel-source that matches your kernel, install it. it's on one of the MDK install CD's.
CLI method............. open a terminal as root, & type the following........
Code:
urpmi kernel-source
hit enter, & that will install the kernel-source. if more than one is available, it will give you a list to choose from. again, choose the one that matches your kernel.
