[expert] Re-configuriing kernel

[Leif Erik Tronstad Svan�]

I'm trying to re-configure my kernel, so I tried to the same as with
redhat as root:
this happend
..]#cd /usr/src/linux
..]#make oldconfig
make: *** No rule to make target 'oldconfig'. Stop.
..]#make xconfig
make: *** No rule to make target 'xconfig'. Stop.

What should I do instead? I'm using Mandrake7.1.
