"Check that you have kernel-source in /usr/src/x.x.x"
They mean that you have to have a copy of the linux kernel. This is normally put in /usr/src/linux.
On mandrake you have to download a kernel from http://www.kernel.org
heres the latest stable version 2.4.19.
>"Modify the file "/etc/modules.conf". Add two lines into it :
alias sound-slot-0 sis7012" This looks like one line to me. Why do they call it two?
Hmm, maybe they smoked funny tobacco they day they made the readme....
Normally you donīt have configure a module, so there i canīt help you.
The thing that you have got is a "kernel module" kernel modules a the drivers for your system which is being loaded when the system boots. But since the kernel in mandy 8.2 is 2.4.18 (isnīt it?). IT should be better if you could get a hold of that one, donīt know if you can get older versions on kernel.org.
