• Use the Add/Remove Software program to install IPK packages
  
  Most software for the Zaurus comes in a format called "IPK"
  (e.g., "someprogram_1.0_arm.ipk"). Place the IPK files on your Zaurus either by:
  
  1. 
     
  2. Using the sync software on the desktop
     
  3. Uploading to the "/home/root/Documents/"
     directory using FTP or SCP
     
  4. Placing the IPK on a CF or SD card (anywhere will do, at the moment)
     
  
  
  Run the 'Add/Remove Software' program (found in the 'Settings' tab of the launcher), click the "Install packages" button, and select the packages to install from the list. (Uninstalled programs will have a icon next to them.)
  
  You are typically given the choice to install the package into "Internal" storage (the storage space inside the Zaurus's RAM), on a CF card, or on an SD card. Note: Some packages fail to install on external cards!
  
  When you're done installing, exit the Add/Remove program, and Qtopia will restart.

• Use the Add/Remove Software program to install packages off the net
  
  Similar to the Debian distribution of Linux, and Familiar Linux-on-iPaq PDA project, the Zaurus can download software packages off of the Internet using 'feeds.'
  
  Add a server (referred to as a 'feed URL'), and then select and install software available from the feed.

• Run the "ipkg" command from a terminal
  
  Instead of using the 'Add/Remove Software' application, you can run the "ipkg" command from within the . (e.g., "ipkg install some.ipk")
  
  Run the "ipkg" command without any arguments to see what else you can do with it. Be sure to restart Qtopia (from the 'Shutdown' app.) to see the newly installed package!

• First, uninstall the old version
  
  Unfortunately, the current 'Add/Remove Software' application doesn't seem to pay attention to version numbers, so you must first remove an old version of a package to be able to upgrade to a newer one. If ANY version of a package is already installed, the 'Install Packages' screen will show the blue 'installed' icon next to the package, even if the IPK is for a newer version.

  If a newly-installed application won't run from the Launcher, and you get welcome with a 'Bus Error' when trying to run it from the , it probably got truncated during install, and, unfortunately, the 'Add/Remove Software' application didn't notice.

  You can download the Quake IPK and data IPK and install them on your Zaurus, if you have space. People have had problems running it from the launcher using the Quake icon in the 'Games' tab.
  You can run it from a command line with:

  It will run, but slowly.

• Yes, but you'll need to install X-Window, first
  
  The Zaurus's "Qtopia" environment runs directly on the video framebuffer, it doesn't use X-Window like Qt for the desktop does on a typical Linux system. To run X11 applications on the Zaurus (e.g., those compiled for Linux running on the iPaq PDA), you'll first need to get the XFree86 packages for the Zaurus.
  Note: You'll need a CF or SD memory card!

• Enable Fast Load
  
  When starting a relatively large application, loading times can be long. A way to bypass this is to enable fast load. Enable it by tapping and holding the stylus pen on the icon of the application. A new screen will pop up, with some info on the program. When the program supports fast load, you will see a checkbox saying:
  
  "Fast load (consumes memory)"
  
  Check it, and the program will be loaded into memory, for faster execution.
  Note that this consumes memory, so you don?t want to enable this for a lot of applications, unless you have a lot of free ram.

• Check the package format, or the package itself
  
  This can happen for 3 reasons:
  
  1) There are two package formats, one for Sharp ROMs and one for OPIE ROMs. The Sharp package installer can only deal with packages for the Sharp ROMs so make sure you get a Sharp package or a package from a Sharp feed.
  
  2) The package is corrupt. Sometimes a package can get corrupted during download. Some browsers seem to partially unpack packages after downloading. Try redownloading the package again and, if possible, use a different browser to download it.
  
  3) The package was not put together properly. The internal structure of a package must follow strict rules, however if you get your packages from reliable feeds and/or software sites you should not have a problem with this.

• Sharp ROM packages are gzipped tar files. OPIE packages are 'ar' files.
  
  On Linux, gzip will be able to unzip a Sharp package, e.g. 'gunzip -t a_package.ipk', and the command 'ar' will be able to unpack an OPIE package, e.g. 'ar -t a_package.ipk'.
  
  If you temporarily change the file extension from .ipk to .tgz WinZip will be able to open Sharp packages, but will fail to open OPIE packages.

• On the Sharp SL5500 3.x ROMs, SL5600 ROMs, and SL-C7x0 ROMs or any based on these, no. These ROMs have an updated package installer that can relocate any package to a FAT formatted SD/CF, even with symbolic links, as long as they only install files to /opt/QtPalmtop. Some packages need to install files to directories that are only available on internal memory however.
  
  On other ROMs such as the Sharp SL5500 2.x ROMs and SL5000D 1.x ROMs then for a package containing symbolic links to be installed to SD/CF, the SD/CF card must be formatted as ext2.

• The package installer does not like spaces and unusual characters in the directory names, where the package is located, as well.
  
  To correct this, find the parent directory where the packages are located that has a space or unusual character in it using the Files tab. Then, with your stylus, tap and hold down on the directory until a menu appears. Select the 'Rename' menu item and remove the space.

• You have 4 options:
  1) Download a package from the OPIE Sharp ROM feed and it should work fine. You normally have to install the libopie and opie-pics packages first. This is best since these applications should have been compiled with the Sharp ROM dependencies
  
  2) For an OPIE package, use dpkg on the command line to install: dpkg -i myopiepackage.ipk
  
  However you cannot uninstall with this and it will generate several errors while installing. There may also be missing dependencies
  
  3) For an OPIE package, install the new ipkg package from ZSI and use ipkg from the command line. This does not enable the graphical compiler to install OPIE packages and there can often be missing dependencies.
  
  4) Peel apart an OPIE package with the 'ar' tool on desktop Linux: ar -x myopiepackage.ipk
  
  Then repackage the bits in the Sharp format:
  tar zcvf myopiepackage.ipk ./debian-binary ./data.tar.gz ./control.tar.gz
  
  (Those './'s in front of the files are important)
  The resultant package can then be installed with the graphical installer, but again may be missing dependencies.

• Qtopia feature
  
  Fast Load is a feature of Qtopia to make applications appear to launch instantaneously. If an application supports Fast Load you can tap and hold the application's icon and in the dialog that appears tick the 'Fast Load' option. Then when you next close the application it will stay in memory and when you launch it again it will appear almost instantly. By default all the PIM apps have Fast Load turned on.

• Similar to FastLoad, but consumes less memory
  
  QuickExec helps to launch applications faster. It is different to Fast Load in that there is a QuickExec process that runs in the background all the time, which keeps all the common parts of applications in memory. When a QuickExec enabled application is launched, the QuickExec process only has to load a library that contains the application specific code. Fast Load on the other hand keeps an entire application in memory, so it leaves less memory free when you are not using the application.
