Systems that are using the 64-bit x86 kernel package
do not need to install the kernel-PAE package because the 64-bit
x86 kernel already includes this support. However, if the system is
32-bit and also supports the PAE and NX features as
determined in the previous section, the kernel-PAE package should
be installed to enable XD or NX support.
The kernel-PAE package can be installed with the following command:
$ sudo dnf install kernel-PAE
The installation process should also have configured the
bootloader to load the new kernel at boot. Verify this after reboot
and modify /etc/default/grub if necessary.
