Sorry, still completely lost.
uname -a gives me the kernel name (2.4.20-4GB-athlon).
Do I need to install a new kernel now?
I have cd'd to usr/src & the only subdirectory there is "packages" - nothing with the name of the kernel in it at all (or even a reference to linux-2.4.20....
Not sure I understand " Find the corresponding source package and go from there." From where? Then what?
Still fairly "green" with linux - used DOS in about 1988, but moved on to XP at home and have forgotten most of what I ever knew with DOS ages ago.
Whilst I know it's very powerful, getting used to command line again is taking some getting used to, especially when I'm not sure what I'm doing (or why!!)
