PND download and installation

Downloading the PND

Use your favorite browser to navigate to the following url: [repo...](Will be available after release) and klick the Download button. Save the File somewhere on your PC. If you use your Pandora to download, you can save it to the directory mentioned in the next chapeter directly.

Installing the PND

Put the downloaded file onto your sdcard into one of the following folders: For Desktop: YOURSDCARD/pandora/desktop For Menu: YOURSDCARD/pandora/menu For both: YOURSDCARD/pandora/apps

If you do this on your PC, insert the sdcard into your Pandora afterwards.

If you use pndstore or some other tool to download and install pnds, please see their documentation for how to use them.

Running the PND

If the above steps worked properly, you should see the Qemu for Pandora icon in the above mentioned place(s) now. (Double)click it to startup the GUI.

Using the UI

Main

Mounting HDD images

Click on the icon with the folder next to "Load image..." to browse your filesystem. Navigate to the imagefile you want to load and select it by doubleclicking it or mark it with a single click and press "open". The help-button will provide some hints on how to do that as well. It is also possible to enter the fullpath including the imagename into the box directly. (e.g. /media/PATHTOYOURSD/qemuimages/freedos.qcow2)

Mounting CD/DVD images

Click on the icon with the folder next to "Load iso.." to browse your filesystem. Navigate to the iso (cdrom image) you want to load and select it by doubleclicking it or mark it with a single click and press "open". The help-button will provide some hints on how to do that as well. It is also possible to enter the fullpath including the isoname into the box directly. (e.g. /media/PATHTOYOURSD/qemuimages/freedos.iso)

Assigning RAM to the machine

Click on the textfield next to "RAM in MB" and enter the amount of RAM in MegaBytes, that the machine should use. If you leave this field blank, the standard value of 128MB will be used.

Launch the machine

When you are happy with all options, you can click the "Launch" button to start the virtual machine.

Exit the UI

If you want to quit the gui, click on the "Cancel" button in the Main tab.

Image Tools

Creating HDD images using the UI

• On the "Image Tools" tab, type in the name of your image in the first textfield without a fileextension. (e.g. test-image)
• Type the desired size of the new image into the second textfield. The size is in MegaBytes. So for a 1GB image type 1024.
• Click on the "Create Image" button.

Your new image will be created in the following directory: appdata/qemu/images/

Other options

Video options

• Use Bochs vga card instead of Cirrus Logic

Simulate a standard VGA card with Bochs VBE extensions instead of the default Cirrus Logic GD5446 PCI VGA

• Fullscreen

Start the virtual machine in fullscreenmode rather than in a window. You can switch between the modes by pressing alt+ctrl+f.

Sound options

• Disable sound

Disable sound by selection this option. (Qemu doesn't support to disable the sound completely, but with this option you will choose a soundcard, that is not supported by most operating systems)

• Adlib card emulation

Emulate an additional Adlib synthesizer card.

CPU options

• 486 CPU instead of pentium

Check this option, if you want qemu to emulate a 486 PC instead of the default pentium PC.

Network options

• Disable Network

Check this, if you do not want qemu to emulate a networkcard.

Installing an OS into an image

Creating HDD images using your Desktop PC (Windows)

-Download Qemu Manager 7 for Windows.

-Install into Windows and run Qemu Manager as Admin.

-go to the Option Qemu Version Management and install Qemu 0.14.1 (You must do this,otherwise QemuManager will use Version0.11 by itself and this Version isnt Compatible)

-Now you can Use the "File/Create new Virtual Disk" Option

-Choose the max Image Size and i recommend the qcow2 Image Format.

Your new empty Image ist now in your QemuManager Folder named "Images"

Troubleshooting

Known problems

We are working on them. If you have found a solution or can provide a patch, please pm mcobit at boards.openpandora.org

• Paths to image or isofiles as well, as imagenames specified in the "Image Tool" MUST NOT contain any whitespaces.
• EMS Memory under Dos is a little Tricky to get work but it work. You must use in Config.sys the Entry "EMM386 M9" and behind Himem.sys must stand nothing,only Himem.sys
