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:
'$ sudo yum install kernel-PAE'
The installation process should also have configured the
bootloader to load the new kernel at boot. Verify this at reboot
and modify '/etc/default/grub' if necessary.
Parameter:
[yes/no]
Technical Mechanism:
On 32-bit systems that support the XD or NX bit, the vendor-supplied
PAE kernel is required to enable either Execute Disable (XD) or No Execute (NX) support.
