重新编译内核 花了 2个多小时 ～～～
http://www.backtrack-linux.org/wiki/index.php/PAE_kernel
NOTE: Do not change any other settings in your kernel unless you know exactly what you are doing!
- In this tutorial we will proceed to enable on Backtrack5 R2.
- We first prepare our kernel and enter the kernel menuconfig.
root@bt:~# prepare-kernel-sources root@bt:/usr/src/linux# zcat /proc/config.gz > .config root@bt:/usr/src/linux# make menuconfig
- After we have launched the ncurses menuconfig we proceed in enabling PAE which can be found at the following: Processor type and features -> High Memory Support(4) --> 64GB
- Once we have enabled PAE from the menuconfig we proceed into building our kernel.
root@bt:/usr/src/linux# make scripts root@bt:/usr/src/linux# make prepare root@bt:/usr/src/linux# make root@bt:/usr/src/linux# update-initramfs -u root@bt:~# update-grub2
- We than reboot and check to see if PAE is enabled. (Adjust the path to your running kernel)
root@bt:~# cat /boot/config-3.2.6 | grep HIGHMEM
