I have an Intel® Desktop Board DH55 mobo (don't know which DH55 like DH55HC or TC etc.) with an Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz. I believe there are 4 GB RAM installed but I only see 3.2:
[]$ pacman -Qq | grep linux
linux
linux-api-headers
linux-atm
linux-firmware
linux-headers
util-linux
[]$ free -m
total used free shared buffers cached
Mem: 3271 2305 966 0 60 851
-/+ buffers/cache: 1393 1877
Swap: 9091 0 9091I believe I need PAE or a 64-bit kernel to address all 4 GBs. I would prefer not to have to reinstall everything, and I have read that PAE should be able to fix this issue, without having to reinstall and reconfigure all of my packages. According to this wiki page https://wiki.archlinux.org/index.php/Ar … of_Arch.3F I see that 64-bit is now recommended, but I was not aware of that when I installed.
Anyhow, if that is all correct, then is the only thing required for me to install this package: http://aur.archlinux.org/packages.php?ID=51326 called linux-pae 3.1.4-1 ?
I find no wiki page on this subject, and the most recent forum post https://bbs.archlinux.org/viewtopic.php?pid=900327 refers to a non-existent AUR package. The other posts I found are at least 2 or 3 years old. This one https://bbs.archlinux.org/viewtopic.php … 68#p356968 does appear to be good instructions for doing this manually, but I'm presuming that the AUR package is intended to handle this in a more automated fashion.
Yes, I realize that I need to backup all of my important data before running this, but I would like confirmation that this is the recommended solution to my problem.

Yes, all you need to do is indeed install the linux-pae package, no need to install abs or edit the .config yourself. After you've installed it, you'll still need to edit your /boot/grub/menu.lst (assuming you use GRUB as bootloader) so you can boot this new kernel (probably /boot/vmlinuz-linux-pae), that's all.
