General

1. What is the Zaurus?
   • A Linux- and Java-based PDA from Sharp
     The Zaurus PDA that this FAQ discusses is the new Linux- and Java-based PDA which was released in the US and Europe by Sharp in the 1st Quarter of 2002.

     It's specifications include:

     • 206MHz StrongARM CPU
     • 64MB RAM (for storage and memory) (5000D has 32MB)
     • 16MB ROM (for OS and built-in apps; flashable/upgradable)
     • 240x320 16bpp (65,536 colors) frontlit 3.5" LCD
     • Linux 2.4 kernel (Lineo's Embedix)
     • PersonalJava (Insignia's Jeode)
     • Qtopia (Trolltech's Qt/Embedded plus apps.)
     • Stereo audio out / Mono audio in (1/8" headphone jack)
     • Buzzer (for alarms/etc.)
     • On-screen handwriting recognition (with word-completion)
     • On-screen keyboard (with word-completion)
     • On-screen letter pickboard (with word-completion)
     • UNICode character-picker
     • 37-key QWERTY thumbpad (similar to Blackberry RIM pagers)
     • IR port
     • USB/Serial docking station
     • Compact Flash Type-2 expansion port
     • Secure Digital / Mulitmedia Card (MMC) expansion port
     • Rechargable, removable battery (Lithium-Ion)

2. How does it relate to other Zauruses?
   • It is similar in form-factor to Japanese MI models
     The Linux-based Zaurus (SL-5500 and the development version, SL-5000D) are similar only in that they are from Sharp and have the same shape and exterior features (keyboard, screen, etc.).

     The Zaurus discussed in this document runs Lineo's Embedix brand of Linux and uses a 206MHz ARM CPU. The earlier Zauruses released in Japan use a proprietary OS from Sharp and a different CPU. They are not compatible.

3. Why should I care about the Zaurus?
   • It's a powerful PDA
     With a 206MHz ARM processor, 64MB of RAM, 16bit graphics, and not one, but two expansion slots, it's among the most powerful PDAs on the market today. It's capable of wireless access, digital photography, music and video playback, full-featured web browsing, gaming, and much more.

     Last updated: 2002.Apr.02

   • It runs Linux - Great for Linux hackers!
     People accustomed to Linux are used to a powerful, stable, open operating system. By using a Zaurus, they get this in their pocket, down to the shell prompt!

     Last updated: 2002.Apr.02

   • It runs Linux - Great for the end-user!
     While many believe Linux isn't easy enough to use for end-users, on a pre-packaged device like the Zaurus, the underlying OS is transparent - the user rarely needs to think about it. And because it runs Linux, there are already many thousands of potential Zaurus developers in the world who will be creating the Zaurus applications of the future, and, thanks to the openness of Linux, helping perfect the Zaurus' existing system software and applications.

     Last updated: 2002.Apr.02

   • It's got a built-in keyboard
     The built-in, hide-away, 37-key QWERTY keyboard (similar to those on some pagers, and available as add-ons for other PDAs) provides an extremely fast method for inputing data onto your Zaurus. Many have already found the keyboard much more convenient than using the Zaurus' trainable handwriting recognition software or on-screen keyboard.

     Last updated: 2002.Apr.02

   • It's expandable
     With both a CF slot and an SD slot, you can add both extra storage space AND useful accessories to the Zaurus at the same time. (Accessories like a digital camera, a GPS device, a wireless NIC, or a modem.)

7. Where can I buy the Zaurus in Japan?
   • Currently, the SL-5500 is not available in Japan
     Probably to keep from diluting the ~25% marketshare Sharp enjoys in Japan with the MI models (which use a different CPU and OS than the SL series), it appears Sharp hasn't yet announced plans to ship the Linux-based SL series in Japan

3. How do I install software onto the Zaurus?
   • 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. Using the sync software on the desktop
     2. Uploading to the "/home/root/Documents/" directory using FTP or SCP
     3. 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.

     Last updated: 2002.Apr.01

   • 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.

     Source: Gilles Fedak
     Last updated: 2002.Apr.06

   • 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!

4. How can I upgrade software? 'Add/Remove' shows the new IPK is already installed!
   • 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.

7. I get 'Bus Errors' when running programs

     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. Try uninstalling it, freeing up some space, and then re-installing it.

8. I heard you can play Quake on the Zaurus

9. Can I run X-Window System programs on the Zaurus?
   • 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!

     XFree86 for Zaurus at SourceForge.

10. How do I switch to X-Window from Qtopia?
    • Terminate Qtopia and start X-Window from the console
      
      • 'Terminate Qtopia' from the 'Shutdown' app.
      • Press at the 'Wait' prompt in the text mode
      • Press to enter text-only mode
      • Log-in as 'root'

12. Can I uninstall the pre-installed software? (e.g., Java demos)
    • Not using the Zaurus itself
      The built-in applications (Opera, the PIM apps., Jeode and the Java demos, etc.) are not installed using the package system, so you can not remove them using 'Add/Remove Software'.

      Last updated: 2002.Apr.06

5. What's the difference between the SL-5000D and the SL-5500?
   • The SL-5000D was an earlier released, developer's model
     The SL-5000D was initially available for USD $399, was available in November 2001, has only 32MB of RAM, and has an all-plastic stylus.

     The SL-5500 is the first consumer model, initially available for $499, available in March 2002, has 64MB of RAM, and has a part-metal, part-plastic stylus. It also comes with an embedded office suite from Hancom pre-installed (presentation viewer, word processor and spreadsheet).

     Internally, other than the RAM size, they seem to be identical. (Software and peripherals are compatible, they physically look the same, other technical specifications are the same, etc.)

LCD Display

1. How do I turn the frontlight off?
   • Push and hold the Menu button.
     Push and hold the button. After holding it for one second, the light should turn on/off.

     Last updated: 2002.Mar.28

   • Adjust the brightness in Light & Power.
     Run the 'Light & Power' application to adjust the brightness of the frontlight.

2. How easy is the display to read with the light off?
   • In bright light, it's very good
     In bright light (outdoors during daytime, or in a brightly lit room or, for example, grocery store), the light isn't actually useful. The display looks similar to GameBoy Advanced screens in these situations.

     Last updated: 2002.Apr.06

   • In a dark room, it's impossible to see
     With the light completely off, it's almost impossible to see in a dark room. With the frontlight at it's lowest setting (under 'Light & Power'), visibility is suitable in a very dark room.

3. My screen seems pushed over to the left.
   • This is for the frontlight
     The Zaurus's LCD display is slightly off-center, pushed to the left about 1mm, to make room for the front-light which is on the right side of the screen.

Batteries and Charging

1. Can I use the A/C adapter without the cradle?
   • The normal A/C adapter works with or without the cradle
     You can unplug the A/C adapter from the back of the cradle, and plug it directly into the bottom of the Zaurus, in the plug.

2. Is there a car adapter for the Zaurus?
   • Not currently
     People have had luck using normal A/C adapters from Compaq iPAQ PDAs, so presumably an iPAQ car adapter could work. One fellow reports: "It does work and fits perfectly." Disclaimer: Doing this may void your warranty!

3. The battery status doesn't seem to accurate
   • It's not the best yet

     Last updated: 2002.Apr.06

   ---

4. How long does the battery last?
   • It depends on how much you use it.
     Listening to MP3s with the frontlight on highest power, the Zaurus lasts only about 1 hour. With typical usage (checking calendar, addressbook, todo list), the Zaurus only needs to be charged every day or so. Your mileage may vary.

5. Do I lose all my data if I let the battery drain completely, or remove the battery?
   • No, the RAM is backed up by another battery
     Along with the removable Lithium-Ion battery, the Zaurus has an internal battery: a small Nickel Cadmium one. It keeps the RAM (part of which contains the program-, data- and configuration-files) from being lost when the Lithium-Ion one goes dead, or is removed from the case. It will only last about 24 hours, though!

6. Why do I have to charge the Zaurus for 24 hours when I first get it?
   • To fully charge the NiCd battery
     The Nickel Cadmium battery that keeps your data safe when the main Lithium-Ion battery is completely drained, or removed, is very small, but it charges at a very low rate. This is probably why Sharp recommends charging the Zaurus for 24 hours the first time.

Expansion Slots and Cards

1. What do CF, SD and MMC stand for?
   • CF stands for Compact Flash
     The Zaurus has a 'Type 2' CF slot, which means it can support larger, 'Type 2' CF devices, like micro-harddrives.

3. I heard CF cards were compatible with PCMCIA cards. Can I use PCMCIA on my Zaurus?
   • Yes, using an adapter
     CF cards and PCMCIA cards are similar, but they are in a different form factor. There are adapters which plug into a CF slot (like on the Zaurus), and allow you to plug PCMCIA devices into it. (They cost approx. USD $50).

     Whether the PCMCIA devices will work once connected, is another story...

4. Are CF and SD memory cards automatically 'mounted' when I insert them into my Zaurus?
   • Yes, CF and SD memory cards are mounted automatically.
     The 'cardmgr' and 'sdmgr' processes running on your Zaurus will notice when a card is plugged in, and automatically mount it.

     You should see a 'SD' (for SD cards) or (for CF cards) card appear on the taskbar, at the bottom right of the screen.

     Last updated: 2002.Mar.28

   ---

5. What format are CF and SD cards usually in?
   • FAT16
     Almost all CF and SD cards are pre-formatted in FAT16 (MSDOS/Windows) format. This is also the format most digital cameras and other devices expect them to be in. (The Zaurus also supports other formats, like Linux 'ext2fs').

     Last updated: 2002.Apr.15

6. How do I get to the files on my SD/CF cards when they're in the Zaurus?
   • They should be available automatically
     Most programs (including the 'Documents' tab of the launcher) will automatically see files on the mounted cards.

     Last updated: 2002.Mar.28

   • They are in /mnt/card and /mnt/cf, respectively.
     When issuing commands from within the program, or when using applications that provide a desktop-computer-style file browser for accessing files, the contents of the SD and CF cards can be found within the "/mnt/card" and "/mnt/cf" directories on the Zaurus's filesystem, respectively.

     Last updated: 2002.Mar.29

   ---

7. Am I supposed to 'Unmount' CF and SD memory cards before physically removing them?
   • Yes, unmounting is suggested.
     In case there is still data left to be written to a file on the SD or CF card, you should 'Eject' ('Unmount') it before physically taking it out of the device. This ensures that the data finishes writing. Once it's done, the card's icon will disappear from the taskbar, and you know it's safe to remove it.

     Last updated: 2002.Mar.30

   ---

8. How do I 'Unmount' CF and SD memory cards?
   • Tap their icon in the taskbar.
     Tap the 'SD' or icon in the taskbar at the bottom of the screen. Select "Eject Card" from the menu that appears. Once the icon has disappeared, it is safe to remove the card.

     Last updated: 2002.Mar.28

   ---

9. I tried to 'unmount' a card using 'Eject', but the icon doesn't go away!
   • Something is still using the card
     Unfortunately, unlike the Linux 'umount' command, the Qtopia GUI's 'Eject' command doesn't give you an error (like "device is busy") if something is still being used on the card.

     Most Qtopia programs are good about 'letting go' of the cards, so they shouldn't cause a problem. If you've got a open, though, make sure you're not in the '/mnt/cf' or '/mnt/card' directory. If absolutely nothing helps, try rebooting from the 'Shutdown' app.

10. How can I write to SD/CF cards using my PC?
    • Use a card reader
      You can purchase a USB Compact Flash card reader for PCs. Some include slots to read other cards, as well.

      Note: Desktop Linux users will need a Kernel capable of USB (version 2.4 or later, and some later 2.2.x versions), and may need to configure the kernel to support CF card readers.

11. Can I use CF microdrives with the Zaurus?
    • Yes, but they may get warm
      People have reported success using CF microdrives (even those as big as 1.0GB) with the Zaurus. Some have been concerned about the amount of heat put out by them, and there's no doubt they'll eat up your battery if you use them a lot. (For example, IBM's Microdrives)

12. Can I use a CF or SD card as memory, instead of file storage space?
    • Set up a 'swap' file on the card
      It is not recommended for normal usage (since writing and rewriting to the same area of flash media will wear it out much more quickly than normal usage), or the faint of heart, but creating a 'swap' file (virtual memory) on a card is possible.

      Set up a swap file, and more "memory" will be available for programs. (Just remember to remove the swap file before unmounting and removing the card.)

      • Open the
      • Create an empty file for use as swap. For example:

        dd if=/dev/zero of=/mnt/cf/SwapFile count=32768

        ("count" is the size of the file in 512-byte blocks, so 32768 is 16MB. "of" specifies the location of the swapfile. In this case, on the mounted CF card.)

      • Turn the blank file into a swap file:

        mkswap /mnt/cf/SwapFile

      • Activate the swapfile:

        swapon /mnt/cf/SwapFile

      You can see the swap by checking the available memory. Run the command "free".

      To turn off the swapfile (you won't be able to eject the card unless you do this first!!!), run the command:

      swapoff /mnt/cf/SwapFile

13. My Internal storage space is running out!
    • Move documents to a CF or SD card using the Documents Tab
      In the 'Documents' tab, if you click-and-hold the icon of a document, you can adjust some of its settings, including where it's stored. If you have room on an external storage device (a CF or SD card), simply change the 'Location' using the pulldown menu, and then click '(OK)' and the file will be moved.

      Last updated: 2002.Apr.05

    • Save new files to the CF or SD card
      Unfortunately, not many, but some applications (like the 'Voice Recorder') allow you to choose where new documents will be stored. If you're running low on Internal space, choose a different storage location.

      Last updated: 2002.Apr.05

14. Can I change the filesystem type on an SD or CF card?
    • Yes ...
      Most SD and CF cards come pre-formatted in Windows FAT16 or FAT32 format, for use in WinCE/PocketPC PDAs, digital cameras, etc. On the Zaurus, you can reformat them to EXT2 format, which is the most commonly-used filesystem under Linux.

      Changing the filesystem to EXT2 is useful because you get case-sensitive long filenames, file permissions and ownership settings, symbolic link support, and more.

IR Port

1. I can't seem to receive beams from other people.
   • Enable Beam Receive

     1. Go to Menu => Connect => Data Comm => Data Accounts => Add New Account.
     2. Select GPRS Data
     3. Give it a name
     4. Set the APN to "orangeinternet" (without quotes)
     5. Leave the user id and password blank.
     6. Save.
     7. Make a note of the CID of the connection, you'll need it later.

     On the Zaurus:

     1. Go to the tab and open 'Network and Sync'
     2. Go to the "Services" tab and click "Add"
     3. Select "Dial-up PPP"
     4. Leave username and password blank.
     5. In the phone number, enter "*99***(CID)#", where "CID" is the CID number from above
     6. On the "Modem" tab, the DNS server addresses are 158.43.192.1 and 158.43.128.1
     7. On proxies, select "No Proxies"
     8. Save.

     Then turn the IR port on your phone on, and start the network connection from the toolbar. Once it connects you can start and browse away.

     To change this to work with other service providers, all you should need are:

     • The APN your providor uses.
     • A username and password, if required
     • The DNS servers (although presumably any public DNS server could be used)
     • Possibly the correct dial string for the phone, although this format might be a GSM standard

7. How do I use the cradle under Windows?
   • For TCP/IP over USB under Windows 2000
     
     • Configure Windows 2000 for connection sharing. In the Network control panel, select your normal Internet connection (properties). Selecting the sharing tab and click on 'Enable...', then select the Local Area Connection that connects to the Zaurus. This will force the USB interface (SL Network) to have an IP address of 192.168.0.1 (netmask 255.255.255.0)
     • In the SL Intellisync, select "Communications Options..." and put in an IP address that's on the same subnet (e.g., 192.168.0.200)
     • On the Zaurus, set up your Internet connection ('Internet Wizard' under 'Settings') to have that same IP address (192.168.0.200), and netmask (255.255.255.0). You probably should also set the default route as the IP address that Windows assigned (192.168.0.1)
     • Put your DNS entries into the Zaurus
     • At this point, the Zaurus should be able to communicate. If it cannot, execute this command in
       route add -net 0.0.0.0 gw 192.168.0.1

2. Why is my Zaurus trying to connect to port 67?
   • It's trying to get an IP using DHCP
     Port 67, in the past used for BOOTP traffic, is now more commonly used for DHCP - to automatically obtain an IP address on a network, and get other related information (like DNS servers, default gateway to use, etc.). The Zaurus is trying to do DHCP.

3. Can I use my desktop browser's bookmarks on the Zaurus?
   • Convert desktop Opera to Zaurus Opera using Perl
     There's a Perl script which you can run on your Zaurus (and possibly on a desktop) which will convert Opera for Windows' bookmarks to Opera for Zaurus' format.

     Source: John Mayson
     Last updated: 2002.Apr.15

   • Converting them yourself
     Opera on the Zaurus uses a simplified bookmark system, and stores its bookmarks in pairs of lines; one the name of the bookmark, the other the URL. For example:

     Yahoo!
http://www.yahoo.com/
Google Search
http://www.google.com/

     (This file is "/home/root/.opera/bookmarks.dat" on the Zaurus.)

     Opera on the desktop uses a slightly more complicated, but also plaintext, bookmark system. Netscape uses an HTML format.

4. I can't telnet into my Zaurus!
   • in.telnetd isn't installed by default
     The default Sharp ROMs don't come with a telnet daemon. ...

     Last updated: 2002.Apr.06

   • Telnet is disabled by default
     Either using the "vi" editor on the Zaurus through the , or by downloading the file via FTP and editing on your desktop, you'll want to edit the file "/etc/inetd.conf" on the Zaurus.

     Find the line that looks like this:

     #telnet stream tcp nowait root /usr/sbin/in.telnetd

     ... and remove the "#" (comment) at the beginning of the line.

     Finally, restart the "inetd" daemon by running this command:

     killall -HUP inetd

5. I can telnet, but I can't log-in as root!
   • Add "ttya1" through "ttya7" to /etc/securetty
     By default, most Unix systems do NOT allow root to connect to the system on anything but the physical terminal.

     Similarly to the above, you'll need to edit the file "/etc/securetty" on your Zaurus. In this case, you'll want to add seven lines, "ttya1" through "ttya7".

8. I can't MGET multiple files off of my Zaurus!
   • MGET won't work with the built-in FTP server

10. Is there a serial comm. terminal for the Zaurus?
    • Yes, minicomm has been ported
      You can get it from the Zaurus Sourceforge site.

      To make minicomm use the serial port by default (and not present an error message about 'Configuration file not found...'), create the file "/etc/minirc.dfl" containing:

       
      baudrate 9600
pu bits 8

      You can use your desktop (keyboard, monitor, mouse) as if it were your Zaurus (keyboard, LCD, stylus) by running the VNC server software on the Zaurus, and a VNC client (like "xvnc" for Linux) on the desktop. Anything you do to the Zaurus' screen over VNC will happen right on the Zaurus, and vice-versa! (This is especially useful for getting the Zaurus' screen onto a projector for demonstrating Qtopia.)

      Restart Qtopia (from the 'Shutdown' app.) and then restart the "inetd" daemon by issuing the following command from within the

      /etc/rc.d/init.d/inet restart

      Qtopia shows the commandline for a second after starting, but it seems to run fine. Remove, or comment out, the line in '/etc/inetd.conf' and restart Qtopia and inetd again to reenable the Qtopia FTP server on port 4242 of the Zaurus.

4. How do I make my Qtopia application 'Fast-Load'-able?
   • Don't call qApp->quit()
     In your C++ source, make sure that you simply close the window for your application, rather than quitting it completely with "qApp->quit();". You should also call "showMainWidget()" on the QPEApplication instance, rather than on the QApplication-inherited "setMainWidget()".

System

1. How do I get a Shell prompt on this thing?
   • Install the Terminal program
     By default, the Zaurus (and most Sharp-released software updates) do not come with a terminal program you can use to get a shell prompt to run the familiar Linux commands (like 'ls', 'cp', 'ping', etc.).

     The standard program (an embedded version of the KDE project's "Konsole") is available from the MyZaurus.com 'Downloads' page.

     A useful alternative to Sharp's Terminal is a version which contains 'tabs', allowing you to run multiple terminals in one window. Embedded-Konsole-Tabs is available at the Zaurus SourceForge project site.

     Last updated: 2002.Mar.30

   • Go into console mode
     When the Zaurus first boots up, before the 'Zaurus' logo appears, there is a text screen containing boot-up messages. At one point, it says "Wait...". If you push the key, and then select the "a" option, you'll be given a log-in prompt.

     If you'd rather not reboot the Zaurus, you can simply drop to text mode and get to the "Wait..." prompt by running the 'Shutdown' app., and select the "Terminate Qtopia" option.

     When you're done in the console, you can simply issue an "exit" command and you'll return to the "Wait..." prompt. Wait about 5 seconds, or push or and the graphical Qtopia environment will start back up.

2. What does 'Flashing the Zaurus' mean?
   • Installing a new/upgraded set of base software
     When Sharp releases updates to the core software for the Zaurus (the Linux kernel, drivers, and standard applications) on their download site, or when third parties (like the Open Source project OpenZaurus release alternative updates, you install them by copying them to the 16MB FlashROM inside the Zaurus.

     When you reboot, the new system will 'unpack' itself into RAM and you'll have an upgraded Zaurus! (Note: Flashing typically, but not always, causes all of your current data and installed programs to be wiped, so you'll want to sync or back-up first!)

3. How do I tell what ROM I have right now?
   • System Info. will tell you.
     The application will usually show you, under the 'Version' tab. (If it doesn't show you, you're running 1.02, and really SHOULD update.)

     Applies to: ROM(s) 1.10 and later

4. How do you flash the Zaurus?
   • Copy a ROM-image to a CF card and do a special reboot
     The 'README' text file that typically comes along with a ROM-image explains all of this, but to summarize:
     1. Back up your data, if you don't want it lost forever!
     2. Switch to 'Replace Battery' and remove the battery cover.
     3. Connect the Zaurus to A/C power
     4. Press and hold the + keys, and push on the back of the Zaurus.
     5. Wait for the and lights to turn off (it should take about 3 minutes)
     6. Push again
     7. Replace battery cover and switch back to 'Normal Operation'
     8. Push and hold to turn the Zaurus back on.

5. What ROMimages work with what Zauruses?
   • 1.x for SL-5000D and 2.x for SL-5500
     The SL-5500 models currently have ROMs in the 2.x range. The SL-5000D developer models have ROMs in corresponding 1.x range. It's not possible to install the wrong ROM on the wrong model of Zaurus

6. Do I NEED a CF card to flash the Zaurus?
   • Yes - They can only be flashed using CF cards
     You must have a recognized, Windows format (FAT16) CF memory card to flash the Zaurus. SD cards won't work, and you currently can not do it via the USB cradle or a serial cable. (Note: People have also used CF microdrives.)

8. Why does the system info. show 100% CPU usage?
   • This is to save power
     100% System CPU usage (the green line) in the display is normal. This is the Linux kernel process, "kapm-idled." When it is 'running,' the CPU is actually halted and not drawing power. It's perfectly normal. As other actual applications require CPU, the red line will go up, and the green line typically goes down the same amount.

9. Does memory work like on PalmOS?
   • No - Memory and storage are split, like regular computers
     Unlike PalmOS, where memory (for running programs) and storage space (for installing programs and storing databases (the Palm's application-centric method for storing data, instead of using files)) are shared, the Zaurus splits the 64MB of RAM between memory (for running programs), and storage (for a Linux "ext2" filesystem).

     Last updated: 2002.Apr.01

   ---

10. Where's all the memory the Zaurus is supposed to have? (Shouldn't it total to 64MB?)
    • Half of it is being used for storage
      Of the 64MB on the Zaurus SL-5500 (32MB on the SL-5000D), typically half of it is used for storage. If you add the total memory with the total internal storage (listed in the app.), it should add up to just under 64MB.

      Last updated: 2002.Apr.01

    • The 16MB ROM is read-only
      The 16MB ROM in the Zaurus is not what is listed as "Internal Storage" in the app. It contains the base system, including the built-in applications (look in "/usr/QtPalmtop.rom/", for example), and is not writable. (It is only ever written to when you flash the Zaurus. See above.)

      Last updated: 2002.Apr.01

    • Available memory includes "Cached" as well as "Free"
      When looking in the app. under the "Memory" tab, only the red, "Used" part of the memory is actually not available. To get an idea of how much RAM is available for new programs to use, total up all of the other values, not just the dark blue "Free" part.

11. Why do I keep running out of memory?
    • The SL-5000D (developer model) Zaurus has only 32MB of RAM.
      Some of the Sharp ROMs (1.10, 1.12) split this RAM up more evenly, providing less RAM for programs to run in (memory), and more space for programs and files to be installed in (filesystem).

      Try using a different ROM which provides more RAM, or use a 'hacked' ROM (like those made by Paul Flinders) which use an SD card for the entire filesystem, leaving almost all 32MB of RAM available for programs to run in.

      Applies to: SL-5000D running ROM(s) 1.10/1.12
      Last updated: 2002.May.20

    • Run fewer programs in "Fast load" mode.
      Click-and-hold the icon for an application in the 'Applications' tab and un-check the "Fast load (consumes memory)" option.

      By default, most ROMs have the , and 'Todo List' applications set to "Fast load".

12. Can I adjust the ratio of memory to storage?
    • SL-5000D users can use a different ROM
      See above: "The SL-5000D (developer model) Zaurus has only 32MB of RAM".

      Last updated: 2002.Apr.07

    • Create a swapfile in Internal storage
      Creating a swapfile in internal storage will provide more space for programs to run (virtual memory), while using some of the storage space. While a swapfile on the ramdisk is less efficient than actually changing the ratio of memory-to-storage, it is more flexible (no need to install a new ROM, and it can be done without rebooting).

      See "Set up a 'swap' file on the card" under the Expansion Slots and Cards section.

13. What's the root password?
    • By default, it is blank
      Unfortunately, the default password for the user "root" on the Zaurus is blank. Presumably, it can be changed by running the "passwd" command from within the program. Whether or not this breaks anything is currently unknown. (It seems to work ok with QtopiaDesktop under Linux)

14. How do I tell how long my Zaurus has been running?
    • Run 'uptime'
      If you launch the and run the Unix command "uptime", it will show you how long the Zaurus has been running - that is, unsuspended (like you'd see on a Linux laptop). Unfortunately, this is not the same as the uptime on a desktop - the amount of since the system was last rebooted.

      Last updated: 2002.Apr.01

    • Run 'last'
      If you launch the and run the Unix command "last", it will show you a log of what users have recently logged into your Zaurus (e.g., over a network connection) as well as when the system was rebooted. Unfortunately, since the time and date is not set the very first time the Zaurus is booted (or booted after flashing the ROM), the first reboot date will be inaccurate.

15. Are any Linux-style logs stored on the Zaurus?
    • You can activate /var/log/messages
      From the , issue the command "/etc/rc.d/init.d/syslog start", and system messages will go into the file /var/log/messages.

      Be sure to turn this off when you're done, because logs can consume lots of storage space! Just issue: "/etc/rc.d/init.d/syslog stop".
