This article sums up the different ways to install Mer on different types of computers (VMWare, chroot, on device, etc.). Please feel free to add/edit. The original information is taken from [[Mer/Releases/0.9]].

Replace "<your version>" with the version you are going to install, e.g. "0.9".

== Installation in VirtualBox  ==

# Unzip zip file
# Open VirtualBox, create new machine (click New):
#* Name: Mer ''<your version>''
#* OS type: Linux
#* Version: Ubuntu
#* RAM: 128MB (at least)
#* Disk: click "existing", find the mer-x86-generic-image-v''<your version>''.vmdk file, select, select
#* Next
# Finish
# Start the newly created virtual machine
# Installing all the needed packages for installing VirtualBox additions:
#* I had to install the following packages by:
#* sudo apt-get install build-essential linux-headers-*kernel-version*-generic
#*(replace *kernel-version* with the currently installed kernel-version on the virtual machine)
#*(you can simply find out which kernel-version you have, by executing "uname -r" in Mer's XTerminal)
# Installing the additions:
#*First of all you have to mount the CD-Image with the additions emulated as a cdrom-device into the virtual machine running mer.
#* Create a new folder with root rights by:
#*sudo mkdir /media/cdrom
#* and mount the virtual device's filesystem to the new mountpoint by:
#*sudo mount /dev/scd0 /media/cdrom
#* If no errors are appearing you can install the additions by:
#*sudo /media/cdrom/VBoxLinuxAdditions[Tab]
#* (please the [Tab]-key instead of [Tab] :) )
# Rebooting the virtual machine:
#* Now, when the installation of the additions has finished, you can reboot the vm simply by:
#*sudo init 6
# Finished

== Installation (chroot) ==

<pre>
mkdir mer-<your version>
cd mer-<your version> && sudo tar xzf mer-x86-generic-image-v<your version>.tar.gz

See [[Mer/Documentation/Making_x86_Mer_Bootable|Making x86 Mer Bootable]]

== N8x0 Install ==

=== The Installer ===

The developers of Mer implemented an installer, which leads through all the steps of installation. In order to use the installer you need to open:
[http://trac.tspre.org/merinstaller.install .install file] with your device, which will prompt you to install the file (about 2.5MB) and add the Extras, Extras-devel and tspre.org repositories if they were not added already.

After the download and the installation go to Settings -> Application Manager -> Utilities -> Browse Installable Applications -> Other and system and you will find a program "Install Bootmenu" and "Merinstaller". If you did not install those by pressing "OK" before, do it now.

The Simple Install will create a bootmenu entry for you. However, for more advanced installations - eg if you already have multiple booting OSes - you might want to read about its [[Mer/Documentation/Bootmenu|configuration]] - you may need to make a .item if you have a clone-to-SD copy of Maemo or Deblet. You can also find out how to change the default boot menu item and other bootmenu tricks.

Assuming you created all the .item files you wanted, go ahead, and start the bootmenu installer from Utilities -> Install Bootmenu. Its advised to close all other applications and network connections, but the installer will tell you all relevant information.

* "Are you sure to continue?" - yes
* "Create backup of current initfs" - yes/no
* "Remove unneeded extra (and factory testing) stuff?" - yes
* "install telnet server for network recovery?" - yes/no
* "install dropbear ssh server for advanced network recovery?" - yes/no
* "/etc/bootmenu.conf found, do you want to add it to initfs?" - yes
* "Ready for flashing this image?" - yes/no

After a successfull flash, the device will reboot and you should see the bootmenu, where you can select the partition you want to boot. Choose the operating system where you just installed the installer for Mer and boot it.

Now start the Merinstaller via Utilities -> Install Mer. Follow the instructions. When prompted for the URL= you can point it to any rootfs image you want. Check at [[Mer/Releases]] or ask at #mer.

Once the installer puts the extracted rootfs to your device you can reboot and chose the partition where you put Mer. Please contribute by filing bugs on [https://bugs.maemo.org/ bugs.maemo.org]

=== Flashable Image ===

'''NOTE: Very experimental, because it doesn't use the Maemo initfs; only install if you want to help test it.'''

Grab a kernel and rootfs image of Mer and flash them directly to the device by:<BR>
<code>
   ./flasher-3.0-static -k mer-armel-n8x0-kernel-v<your version>.zImage -r mer-armel-n8x0-image-v<your version>.jffs2 -f -R
</code>

You might want a MMC card swap partition.

== 770 Install ==

'''(these instructions need testing)'''

You will need at least a 1gb MMC, and these instructions are based on OS2008HE kernel. 48mhz kernel is highly recommended

Partition MMC to:

*p1: Large ext3 partition first
*p2: 256 MB swap partition second

Grab http://packages.tspre.org/pool/user/b/bootmenu/bootmenu_1.5-2_armel.deb and install it.

* Open the main menu and tap Utilities -> Install Bootmenu to start the bootmenu install process.
** If nothing happens, install xterm
** If window appears and then goes away, gainroot is not installed
*** Alternative method with dropbear client / server installed, start xterm, run dbclient root@0, password 'rootme', run /usr/sbin/install_bootmenu
* First, say yes to removing "unneeded extra (and factory testing) stuff"
* say yes to including bootmenu.conf (important). Reboot when done flashing.
* This is a special boot menu where boot menu items are made in /etc/bootmenu.d/*.item and refresh_bootmenu.d will flash this to initfs. '''If you are cloning or booting other OS'es, you'll need to make such .item files'''. See [[Mer/Documentation/Bootmenu]]

Grab e2fsprogs and install it - grab gnutar as well

*From x-terminal, root: insmod /mnt/initfs/lib/modules/current/mbcache.ko
*insmod /mnt/initfs/lib/modules/current/jbd.ko
*insmod /mnt/initfs/lib/modules/current/ext3.ko
*mkfs.ext3 /dev/mmcblk0p1
*mkswap /dev/mmcblk0p2 
*swapon /dev/mmcblk0p2
*mkdir -p /mnt/mer
*mkdir -p /etc/bootmenu.d
*mount -t ext3 /dev/mmcblk0p1 /mnt/mer
*cd /mnt/mer; wget <nowiki>http://stskeeps.subnetmask.net/mer/<your version>/mer-armel-770-image-v<your version>.tar.gz</nowiki>
*tar pzxvf mer-armel-770-image-v<your version>.tar.gz
*rm mer-armel-770-image-v<your version>.tar.gz
*umount /mnt/mer
*Make /etc/bootmenu.d/mer.item with the following contents:

<pre>
ITEM_NAME="Mer"
ITEM_ID="mer"
ITEM_DEVICE="mmcblk0p1"
ITEM_MODULES="mbcache jbd ext3"
ITEM_FSTYPE="ext3"
ITEM_FSOPTIONS="noatime,ro"
ITEM_LINUXRC="linuxrc"
</pre>
*refresh_bootmenu.d (say yes to reflashing, no to backup of initfs. reboot)
*Hold down Menu key when prompted while booting and select Mer in the boot menu.

== BeagleBoard port ==

* Make sure you are running a RECENT uBoot, and you have USB input devices like keyboard or mouse, if you don't own a touchscreen..
* Make a SD card, partitioned with 50mb FAT as first partition, extract boot fs on this, and the rest Linux partition, format this as ext3, and extract rootfs on this.
* In uBoot, use the following commands (you may have to adjust video= parameter to match your display screen:

'''Note: The format of the video bootargs parameter has changed for the new 2.6.28 kernel in 0.9. You'll likely have to update the bootargs line.'''

<pre>
setenv bootcmd 'mmcinit; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait omapfb.video_mode=1024x768MR16@60'
saveenv
boot
</pre>

* The tablet should output kernel output on serial and on video, and on HDMI out it will eventually start X and show the First Boot Wizard. Good luck.

== Pocket Loox 720 port (experimental) ==

* Set up a SD card with a logical partition, and inside this logical partition, make a 50mb or so FAT partition (p5), and put the zImage file on this filesystem, name it zImage. After the logical partition, make a ext3 partition (p2), and untar rootfs on it.
* Grab [http://www.handhelds.org/moin/moin.cgi/HaRET HaRET] and put it on the FAT partition, HaRET.exe.
* Make a file, startup.txt, with the following contents:

<pre>
set kernel "zImage"
set mtype "617"
set RAMADDR "0xa8000000"
set cmdline "mem=128M rootdelay=1 root=b302 rw console=tty0"
boot
</pre>

* Unmount all filesystems, insert SD card into Pocket Loox, boot by running HaReT.exe. If HaRET stops with "Jumping to kernel..." then grab [http://dl.free.fr/dZ75nlNFA/loox_boot.tgz HaRET] from www.postnuklear.de/linuxloox.
* Experimental release, if you want to play with this - come hang out on #mer on irc.freenode.net and we'll try to guide you along. It is a 640x480 screen so our theme won't fit.

* For using ssh between loox and desktop box :
- You need to grab an ssh enabled [http://www.daimi.au.dk/~cvm/loox.tar.gz rootfs].

- extract it on your sd card (ext3 partition)

- connect the Loox with the sync cable to your desktop box. And power on loox.

- on your desktop box check for USB network interface (usualy usb0) with : ifconfig

- configure the USB network interface : sudo ifconfig usb0 192.168.2.1

- ssh to loox : ssh root@192.168.2.2

- root password is 'rootme'

* If touchscreen is not calibrated MER v0.11:
- download [http://ports.ubuntu.com/pool/main/t/tslib/libts-bin_1.0-4ubuntu2_armel.deb tslib-bin] to your desktop box.

- scp the deb file to loox : scp libts-bin_1.0-4ubuntu2_armel.deb root@192.168.2.2:/root

- on loox : dpkg -i libts-bin*.deb

- run ts_calibrate (all in one line) :
<pre>
TSLIB_CONFFILE=/etc/ts.conf TSLIB_TSDEVICE=/dev/input/event0 TSLIB_FBDEVICE=/dev/fb0 TSLIB_CONSOLEDEVICE=none TSLIB_CALIBFILE=/etc/pointercal ts_calibrate
</pre>
- you can test your touchscreen with ts_test

* If touchscreen is not working under Xorg MER v0.11 :
remove xorg synaptics driver
<pre>
apt-get remove xserver-xorg-input-synaptics
</pre>

* Internet on Loox
- Configure MASQUERADE on you desktop
<pre>
iptables -A FORWARD -s 192.168.2.0/24 -j ACCEPT
iptables -A FORWARD -d 192.168.2.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -s 192.168.2.0/24 -j MASQUERADE
echo 1 >/proc/sys/net/ipv4/ip_forward
</pre>

== Touch Book (Experimental) ==

'''Until there's a Touch Book image, use SmartQ5 image.'''

First, make sure your SD card's geometry is 63 / 255 . Otherwise the Touch Book won't recognice it. To set the correct geometry, put the SD in your host-computers card-reader and open up a terminal. Type:
<pre>
bash:$ sudo fdisk /dev/<yoursdcard>

Command (m for help): [x]

Expert command (m for help): [s]
Number of sectors : [63]

Expert command (m for help): [h]
Number of heads : [255]

Expert command (m for help): [w]
</pre>

'''Formatting the SD card:'''

* The first partition needs to be formatted as FAT32 ''and have the boot flag''. 30Mb size is fine.
* Format the second partition as ext3, at least 512Mb size.
* If you want, you can also create one more partition for swap.

This is easy to do with linux host-computer.
GParted is easy to use graphical Partition Editor.

'''Installation'''

Download Mer image and unpack it in the second partition.

Copy a few files from AI OS for better hardware support:

/lib/firmware

/lib/modules

/etc/Wireless

/etc/fstab

== SmartQ ==
Dual booting doesn't seem to work at the moment.

You'll need an SD card with a FAT32 as the first partition and more than 140MB free.

Download the correct firmware image and rootfs image from the Released Images table.  Copy both of them to the root of the FAT32 partition on the SD card.

Rename the firmware image to either 'SmartQ5' or 'SmartQ7' according to your device.

You may also want to download some additional software to our SD card for after Mer is installed.<br>
To use Wifi, you'll need the Marvell Wifi Firmware blobs
* Browse [http://www.marvell.com/support.html here] and select in the drivers colum for os "Fedora 2.6" and click search. After that, get a zip file called starting whit SD-8686
* Extract the downloaded zip file, then extract SD-8686-FEDORA26FC6-SYSKT-GPL-9.70.3.p24-26409.P45.tar within it. Extract the FwImage folder to your PC.
* Inside there are two files, helper_sd.bin and sd8686.bin. Rename helper_sd.bin to sd8686_helper.bin and copy to your SD card

The commands to extract and copy it might look like this:
 cd /tmp
 unzip SD-8686-LINUX26-SYSKT-9.70.3.p24-26409.P45-GPL.zip
 tar xf SD-8686-FEDORA26FC6-SYSKT-GPL-9.70.3.p24-26409.P45.tar
 cp FwImage/helper_sd.bin /path_to_SD_CARD/sd8686_helper.bin
 cp FwImage/sd8686.bin /path_to_SD_CARD/sd8686.bin

Wifi WPA2 fix
* Download the [http://www.daimi.au.dk/~cvm/kernel-smartq5-modules_2.6.24.7-smartq5-050509_all.deb SmartQ5] or [http://download.opensuse.org/repositories/Maemo://Mer:/Devel:/HW:/SmartQ:/Devel/MerDevel_Ubuntu_9.04/all/kernel-smartq7-modules_2.6.24.7-smartq7-20090729_all.deb SmartQ7] WPA2-fixed driver to your SD card.

Now unmount the SD card and eject it.

Power off the SmartQ totally (wait for the LED to go out) and insert the SD card.

===SmartQ5===
Press and hold the + button and insert the charger.
The device will begin to boot; the LED will be green/yellow.
A series of chinese characters will appear ending with '...' if all is going well.  Once you see them, you can release the + button.  Next there will be
a progress bar.  Once it completes, the device will automatically reboot.

===SmartQ7===
Press and hold the 'menu' key (bottom key on front) and insert the charger.
The device will begin to boot; the LED will be a different colour - green/yellow. You can release the menu key. Some chinese symbols appear and then a progress bar ticks (slowly) up to 100%.  Once it completes, the device will automatically reboot.

===both===
After this a calibration screen will appear and shortly after you are in Mer.

If you have connected it to a computer via USB, it will be accessible over USB networking on IP 192.168.2.15 ([http://wiki.maemo.org/USB_networking#Host_USB_Network_Configuration see instructions here]) with a SSH server, login root, password rootme

It will not show a splash screen, but it will after darkness then make the screen white, and eventually, show the Mer background and first boot wizard.

=== To mount your SD card ===
In Mer on SmartQ, open X-Terminal and type (tab-completion is your friend):
<pre>
$  sudo mount -t vfat /dev/mmcblk1p1 /media
</pre>
When prompted for a password, enter the one you set when you first started.
Note that the above device name has one lower-case L character and then two number one characters (these can look quite similar in some fonts).

=== To get wireless networking (including WPA2) to work===

In order to get wireless networking to work, you are going to have to install the Marvell firmware you copied onto your SD card, and to get WPA2 working, you'll also need to install the .deb.  The first step is to mount your SD card (see the section just above this, if you haven't already mounted it).

So, in Mer on SmartQ, open X-Terminal and type (tab-completion is your friend):
<pre>
$ sudo cp /media/sd8686.bin /lib/firmware/
(if prompted, the password is the one you set when you first started)
$ sudo cp /media/sd8686_helper.bin /lib/firmware/
</pre>
And then either, for the SmartQ5 [Note: The following step may not be necessary as the 0.16-5 firmware automatically installs the most current file from the SD card during bootup. The confirmation message is "wifi firmware installation successful". Verified on Q5.]
<pre>
$ sudo dpkg -i /media/kernel-smartq5-modules_2.6.24.7-smartq5-*_all.deb
</pre>
or for the SmartQ7 [Note: The following step may not be necessary as the 0.16-5 firmware automatically installs the most current file from the SD card during bootup. The confirmation message is "wifi firmware installation successful". Verified on Q7.]
<pre>
$ sudo dpkg -i /media/kernel-smartq7-modules_2.6.24.7-smartq7-*_all.deb
</pre>

Now that you've enabled networking, you should close the gaping security hole which is part of the default configuration by changing the root password from its default, which is "rootme".
<pre>
$ sudo passwd
Password:   (enter your user password)
Enter new UNIX password:   (enter any hard to guess password you want)
Retype new UNIX password:   (same one again)
</pre>

Next you should reboot.
<pre>
$ sudo /sbin/reboot
</pre>

Once it reboots, you should be able to see wireless networks on the menu and select them.

=== Booting from SD card ===
(this was taken from [http://alone-in-the-light.zenvoid.org/2009/06/boot-smartq-5-from-sd-card.html zenvoid's blog])

In order to boot from the SD card, it is simply a matter of creating a partition on the SD card large enough to hold the mer distribution, but leaving enough unpartitioned space at the end of the card for the bootloader to sit.

* Download install-smartq-qi.sh, qi-smartq-20090612.bin from http://zenvoid.org/software/qi-smartq

* Create at least one ext2/ext3 Partition your SD card (and optionally a swap partition), but always '''remember to reserve 1 MiB of free, unpartitioned space at the end of the SD card'''. To be precise, at least the last 2048 blocks (512 bytes each) must be reserved.
* Untar (tar --numeric-owner -zxvf) the rootfs for your device onto the partition you created on your SD card (make sure it isn't mounted with any no* options, e.g. nodev, noexec, ..)
* Rename or copy the kernel file (/boot/zImage<something>)  to /boot/linux-SMDK6410.bin
* Run
<pre>
./install-smartq-qi.sh /dev/SD_CARD_DEVICE qi-smartq-20090612.bin
</pre>

To boot from the SD card, keep the "move"/fullscreen button (Q5) or right-hand-most button on the top which looks like a target symbol (Q7) pressed and then press the "power" button.

Q5 Boot stages:
* Red LED: First stage - bootloader is loading itself into memory.
* Yellow LED: Second stage - bootloader running, trying to locate and loading a kernel image.
* Green LED: Linux kernel loaded and running.
* Blinking yellow LED: A critical error while reading from the SD card.
* Blinking green LED: No kernel found.

Q7 Boot:

Keep in mind that the LEDs colours are reversed on the Q7, i.e. a green LED on the Q5 is a red one on the Q7 (the list above is for the Q5)

There is no battery check at the moment.

==== Alternate SD booting method using the OF bootloader ====
(as desribed on the Smartqmid forum: 
http://www.smartqmid.com/phpBB3/viewtopic.php?f=2&t=150)

'''works only with OF installed on the device'''

in short:
*the first partition must be fat32 and the other primary partitions must be ext3
*on the first (fat) partition must be a folder named boot, that contains a menu.lst file and the kernel image (zimage)
*the menu.lst should be formated like this:
<pre>
title sdcard # name of the entry
kernel /boot/zimage # kernel image location
param root=/dev/mmcblk1p2 rootwait # location of the root fs, this is
                                   # the second primary partition on SD 
                                   # the internal memory is mmcblk0,
                                   # first internal partition = mmcblk0p1

</pre>

With all this in place, the device shows a simple boot menu when turned on wit the SD card inside, you can select the entry with +,- buttons on the left and booting is triggered with middle button on the upper left.

Theoretically you can multiboot up to 5 different systems (internal + on the fat partition + three ext3 partitions, '''not tested''').
