BIOS sees memory upgrade but Linux Mint 12 does not

Good afternoon.  Today I upgraded my main Linux Mint 12 system to 8Gb of RAM (I do a lot of software testing with virtual machines).  Came across one little problem though. The RAM upgrade was recognised in BIOS but not by the operating system.  Time to do some research.  It turns out the default 32-bit installation of Linux Mint 12 does not have a PAE (Physical Address Extension)-aware kernel installed.  Well that is easily fixed.

Open up a terminal and type:

sudo apt-get install linux-generic-pae linux-headers-generic-pae

And then restart.  Upon restarting, the system will have the full complement of RAM to play with!!!
