Hi To add kernel support for my wireless card. I updated my kernel from 2.6.18-92.1.18.el5 to 2.6.27 The update was successful however now when I run 'yum list installed' I get kernel.i686 2.6.18-92.el5 installed kernel.i686 2.6.18-92.1.18.el5 installed kernel-devel.i686 2.6.18-92.1.18.el5 installed kernel-headers.i386 2.6.18-92.1.18.el5 installed Is there something I must do to inform yum that I am now running 2.6.27 Also how would I update my kernel headers and devel Is there a command to view my currently installed kernel-headers and kernel-devel. I can use uname -a and it displays the running kernel. How would I install my kernel-headers and kernel-devel from source. Thanks A
