Hi List,

I have a program that runs with kernel 2.6.22, but when I tried to compile wit kernel 2.6.27 it occurs errors:

[root@localhost madwifi-0.9.4]# make
Checking requirements... ok.
Checking kernel configuration... ok.

[root@localhost madwifi-0.9.4]#

my question is:

Can I have both

kernels 2.6.22 and 2.6.27 at the same time. And When I want to compile any program use any of them ?
Is it possible and how ?

thanks,
