Hi,

My laptop has only 2GB of RAM so I don't think I need the PAE kernel, also there are some drivers that I want to install, they were built for non-PAE kernel.

So far I read that I have to change the :

/etc/sysconfig/kernel
---------
# UPDATEDEFAULT specifies if new-kernel-pkg should make
# new kernels the default
UPDATEDEFAULT=yes

# DEFAULTKERNEL specifies the default kernel package type
DEFAULTKERNEL=kernel-PAE
--------

to DEFAULTKERNEL=kernel

then I suppose I have to do:

yum install kernel


but what next? I mean the nvidia drivers etc, will be updated automaticaly?
(also on the grub menu) ?

regards

You can do the following command in a terminal:

yum list installed |grep PAE

and that should show which packages you have to replace with the non PAE versions (nvidia, wireless, etc).

Installing a kernel should update the grub menu so you should be okay there.

Hello! is there a way to NOT uste the PAE kernel from the very start?
what i mean is, when about to install fedora, pass some boot option to anaconda or something, so that it will NOT use the PAE kernel but use the "normal" one instead?
I want to use the normal one, and i would like to make a clean install with a non PAE kernel from the start.
Thanks!

EDIT: if for some reason,its not possible to install fedora to use the non-PAE kernel...
after a fresh install, whats the earliest point at witch i can ditch the PAE kernel and configure it so it will (from now on) ALLWAYS use the standard non-PAE kernel?
