I'm trying to install NdisWrapper on my laptop, since my wireless card isn't supported by linux. I followed all the steps, but I found out that the kernel source wasn't in the /usr/src folder. Is there an easier way to install this, like an RPM or something? If not, where is the Kernel source on mandrake 10.1?

Make SURE your urpmi sources are set up. See my sig for directions.

Then determine the name/version of your installed kernel.

e.g.

uname -a

Now there is one minor problem....

urpmi kernel-source

will automatically download and install the LATEST kernel available on the repositories.

This may not correspond to what you have installed!

So you can either exactly specify the kernel source you wish to install (browse the urpmi ftp sites in a browser to see) or go ahead and install the updated kernel.

Keep this in mind.

BTW: If you have NOT set up your URPM sources you can

urpmi kernel-source

which will install the version from your CD/DVD's. It should correspond to the original kernel.

Finally you can also mount the disk(s) them

cd /mnt/cdrom/xxxx

To get to the RPM/Media directory and

rpm -Uvh kernel-source-xxx.rpm

again making sure that you are installing the kernel-source for the installed kernel.

Well, right not I have the kernel 2.6.8.1-10mdk installed. Would that mean I should type in "urpmi kernel-2.6.8.1-10mdk" ?

Your best bet would be to look at the ftp repositories and find the kernel-source rpm which you need.

You can do this from any browser or ftp client.

The repositories are nothing more than anonymous FTP sites (or in some cases http sites).

Could I not add in the sources and do it from the CD?
I mean not follow the steps in your sig and just do "uprmi kernel-source"?

Yes, if you have not updated the kernel since you set up Mandrake.

If you have not then the kernel-source rpm on the CD's will do fine.

Just mount the disk and find the RPM, change to the directory containing the source then

rpm -Uvh kernel-source-xxx.xxx.rpm
