more ram


I need more ram for the t400

I ordered two 2gb modules for my laptop. Turns out I would have needed only one: the t400 comes with one 2gb preinstalled.

Next: it only shows 3gb instead of 4gb (on ubuntu).  Problem solved:

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

Next: how can I use a ramdisk - problem is that I need to copy e.g. my plone or bfg installation into that ramdisk, and need to then mount that to my old location.


mkdir -p /tmp/ram
sudo mount -t tmpfs -o size=512M tmpfs /tmp/ram/
mount --bind /tmp/ram /new/directory/path
