Pre-Notes: - This will work only if your Linux Distro is based on RPM and YUM. I have tested it on Fedora but it may also work on RHEL and Centos... It will NOT work on Ubuntu, Debian, Suse... - The operating system and its version will be the same inside and outside the chroot jail. - On the example, the chroot will be placed at: /chroot/devel - To install different version of Fedora or other RPM based distro, it will be necessary to manage yum package repositories outside the jail. The five steps: # 1 - Create the chroot directory $ sudo mkdir -p /chroot/devel/var/lib/rpm # 2 - Initiate rpm db on chroot $ sudo rpm --root /chroot/devel --initdb # 3 - download Fedora Release package. # If you do not want Fedora, download the correct *-release package and use it # on step 4. There are examples on the references. $ yumdownloader --destdir=/tmp fedora-release # 4 - Install downloaded Fedora release inside chroot $ sudo rpm --root /chroot/devel -ivh /tmp/fedora-release*r

The datasheet of Toshiba R830-10P mentions that the maximum memory capacity is 8GB. See it here . But Intel says that the i7-2620M supports up to 16GB of RAM. See it here . I have asked for help on Toshiba Forums. Nothing useful from there. See it here . I was curious as I have a very particular need for 16GB of RAM. Today I decided to give it a try. I bought two Patriot PSD38G13332S (8GB PC3 - 10600 1333MHz CL9 SoDimm) and installed it on the notebook. It just worked. So if you have the need for 16GB of RAM and a similar notebook from Toshiba, you can install 16GB of RAM.
Fedora live images do not include the "Boot to RAM" option any more. This is not a big problem as the scripts needed to boot to RAM are still there. You just need to add rd.live.ram as boot option. To do that, highlight "Start Fedora Live" using the keyboard keys and press TAB to edit boot command line. Add rd.live.ram and press Enter. Press TAB to edit boot command line Add: rd.live.ram Press ENTER
