Install Ubuntu Server 8.04 LTS or better on a VMWare machine.
sudo apt-get update && apt-get dist-upgrade
sudo apt-get install tftpd-hpa dhcp3-server openbsd-inetd tftp-hpa
Backup and replace /etc/dhcpd3/dhcpd.conf with the attached file.
Backup and replace /etc/inetd.conf with the attached file.
Download the correct netboot package:
http://archive.ubuntu.com/
http://archive.ubuntu.com/
etc.
Lucid doesn't have an updated one yet:
http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/netboot.tar.gz
or
http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-i386/current/images/netboot/netboot.tar.gz
mkdir -p /tftpboot/32bit
cd /tftpboot/32bit ; tar -zxf ~/netboot.tar.gz
Depending on if you want to install 8.10 or 8.04... 8.10 advised at the mo.
Boot the Eee once over the network. It won't. Note down the IP address.
Edit /etc/dhcpd3/dhcpd.conf and change the following for your env:
hardware ethernet 00:1E:8C:5C:7D:42;
fixed-address 192.168.1.100;
next-server 192.168.1.64;
filename "32bit/pxelinux.0";
option routers 192.168.1.254;
option domain-name-servers 192.168.1.254;
replacing the hardware ethernet with the Eee's MAC.
Restart the dhcpd daemon. Make sure inetd is running, if not invoke the daemon.
This step is very critical: PLUG THE FRIGGIN' CABLE TO THE EEE...
Reboot. Enjoy.
Then it's a matter of spending a couple of hours while it downloads everything over the net and installs.
Once the installation is done, add the following to /etc/apt.d/sources.list:
deb http://www.array.org/ubuntu intrepid eeepc
save, exit.
wget http://www.array.org/ubuntu/
sudo apt-key add array-apt-key.asc
sudo apt-get update
sudo apt-get install linux-eeepc
(more stuff here http://array.org/ubuntu/setup-
Get the kernel. Reboot.
Download the latest Skype from skype.com and install as usual.
Do the following: (stolen from www.ubuntu-eee.com/wiki). The rest are copy-pasted from the wiki. I did most of them, esp. removed the tmp to ramdisk and did the powernowd installation and configuration.
----8-------------------------
Move /tmp, /var/tmp, /var/log and /var/log/apt into RAM
Using the fstab file we can move temporary data and log files into RAM. This process mounts each location as a temporary file system.
sudo gedit /etc/fstab
Add the following lines to the bottom of your fstab file.
Wicd 1.5 users: Do not add the last 2 lines otherwise the Wicd daemon will fail to start. This is a known Wicd bug.
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/log tmpfs defaults,noatime,mode=0755 0 0
tmpfs /var/log/apt tmpfs defaults,noatime 0 0
Note: Your log files will vanish after each reboot. But other than that, there are no harmful side effects from this operation.
You might add also unionfs for /var/cache at the end fstab:
none /var/cache unionfs dirs=/tmp:/var/cache=ro 0 0
[edit] Tweak Primary File Systems
The following options can be added to your remaining partitions to help lower disk writes:
* Use the "noatime,nodiratime" options for any of your reiserfs partitions in /etc/fstab. This also gives slightly faster filesystem performance.
* Use the noatime option for any of your ext3 partitions in /etc/fstab. See Geek Sheet's blog for more details.
* Use a the non-journalling filesystem ext2 at the cost of data reliability.
[edit] blkid.tab and mtab
The following commands can be executed to further reduce disk writes. If you wish to mount anything through fuse the second set of instructions will likely cause problems, if you go ahead and later need to mount something, instructions for removal of this link can be found on the talk page for this article.
sudo rm -f /etc/blkid.tab*
sudo ln -s /dev/null /etc/blkid.tab
sudo rm -f /etc/mtab
sudo ln -s /proc/mounts /etc/mtab
See Debian Administration for more details.
CPU Frequency scaling
(Note that this seems not to be necessary when using ubuntu-eee 8.04)
* Edit /etc/modules
sudo gedit /etc/modules
* Add the line
p4_clockmod
* Make sure powernowd is installed (I think it's by default) otherwise install it using
sudo apt-get install powernowd
[edit] Laptop-mode
Alternatively enable laptop-mode
* Enable laptop mode by editing /etc/default/acpi-support
ENABLE_LAPTOP_MODE=true
* Edit /etc/laptop-mode/laptop-mode.
ENABLE_LAPTOP_MODE_ON_BATTERY=
* Disable all HD features as eeepc uses a SSD
CONTROL_HD_XXX=0
* Tune the cpu scaling options, too aggressive settings will make performance too slow. This setting works ok:
BATT_CPU_GOVERNOR=performance
You can check the current cpu frequency with
cat /proc/acpi/processor/CPU1/
Whit these settings, the cpu stays mostly at 50%, and increases imediatly by demand, like when opening webpages in firefox.
