MEDIA TOOLBOX System Program
Purpose: To partition and configure hardware devices.
Template: (none)
Path: SYS:System/Media Toolbox
MEDIA TOOLBOX enables you to partition and configure hardware devices for use with OS4 and Linux, and should be used with caution as incorrect use could destroy all data on your hard drives.

When executed, the following window will open:

AmigaOS Media Toolbox Device Selection window

First you must select the device that you want to configure. This will normally be 'a1ide.device' for the onboard VIA controller, or it may refer to an add-on controller card that you have installed, for example 'sii0680ide.device' if you have installed a SiI0680 controller card.) USB connected devices are also selectable from here.

'Program mode' near the bottom of the window will typically say "Expert", or you can change it to "Normal" depending on what you want to do. "Expert" mode gives you more advanced options. The following examples depict only the 'Normal' mode of operation.

Click on the Start button to display the Media Toolbox Unit Selection window:

AmigaOS Media Toolbox Unit Selection window

This displays all of the units connected to the selected device. Initially nothing will be selected, and all buttons will appear ghosted. Because there can be multiple units for that device (as shown) you must select the appropriate unit. Once the unit is highlighted, the buttons below the unit list will become un-ghosted as shown below:

AmigaOS Media Toolbox Unit Selection window

In this instance the selected unit has not yet been installed, so it will be shown as 'Not installed' and the Install... button will be un-ghosted.

Clicking on the Install... button will display the following screen:

AmigaOS Media Toolbox RDB/disk geometry editing window

As you can see this displays the drive configuration but at this time it may not necessarily be correct. The next step is to click on the Install/read configuration... button. The following requester will then appear:

AmigaOS Media Toolbox Reinstall disk? requester

If you are installing on a previously unused or unpartitioned hard disk, click Yes to lose *ALL* data. You will then be returned to the previous screen as shown below:

AmigaOS Media Toolbox RDB/disk geometry editing window

The next step is to install the AmigaOne booter by clicking on the Install AmigaOne booter button. A requester will appear from which you must choose the A1 booter to be installed:

AmigaOS Media Toolbox Select AmigaOne boot code requester

This is where life can get a little confusing because the SLB has been updated many times but in most instances the name has stayed the same 'slb_v2'. We recommend that you change the name to reflect the version and keep old versions in case you have to go back for some reason. However, unless there is a known problem, we recommend that you always use the latest version. Failure to use the correct version can produce unpredictable results from the Second Level booter. At this point in time we would recommend that you select slb_v2.1.16 (which should show as 27,829 bytes with a compile date of 23/01/06 13:50) and click on Ok.

AmigaOS Media Toolbox RDB/disk accept changes window

The window now shows that the AmigaOne booter has been installed, but that is not strictly true, until you you click on the Ok - accept changes button. This writes the changes to disk and returns you to the Media Toolbox Unit Selection window:

AmigaOS Media Toolbox Unit Selection window

The selected unit now shows as 'Ready' so we can now start partitioning the drive.

The Edit RDB/Reinstall... button can be used in future to edit the Rigid Disk Block, or to reinstall the AmigaOne Booter or 'SLB', similar to what we have just done.

However, the next step for now is to click on the Edit partitions and filesystems button. Another screen will appear that shows the partitions configured on the disk drive.

AmigaOS Media Toolbox AmigaOS disk partition definition window

Since the drive at this time is completely empty, nothing will appear. The available space is shown by the large shaded block in the center of the window. Click on this block and a white border should appear, and the Add partition button will become unghosted as shown:

AmigaOS Media Toolbox AmigaOS disk partition definition window

Click on the Add partition button to start defining the first partition as shown:

AmigaOS Media Toolbox AmigaOS disk partition definition window

The partition name should show a default (e.g. DH0:) and will default to the full available drive space in bright green corresponding to the File system type which defaults to DOS/03.

The next step is to change the partition size by moving the arrow at the right of the sizing bar, towards the left of the screen to get an approximate size, and then using the + and - gadgets on the right of higher cyl to fine tune the exact sizing as shown:

AmigaOS Media Toolbox AmigaOS disk partition definition window

In this example we have set the DH0 partition to approximately 5 Gigabytes, and we now ready to update the partition characteristics by clicking on the Select file system / edit details button. This will open another window containing the Filesystem details as shown below:

AmigaOS Media Toolbox Partition File System details

For Amiga partitions we recommend you select both FastFileSystem, and Long filenames as shown below and click on 'Ok - accept changes' to return to the previous window:

AmigaOS Media Toolbox AmigaOS disk partition definition window

Notice that the File system has changed to 'DOS/07' and the colour of the allocation has changed to orange. Given that DH0 would normally be the boot partition you must also ensure both Automount and Bootable are selected by clicking on the tick boxes underneath the partition editing bar. DO NOT alter the boot priority which will default to -127.

To create additional partitions, simply repeat the above steps as required, although they may not need to be bootable. If you want to create partitions for installing Linux on the same hard drive as OS4 the steps required for this are covered here. Once you have completed your definitions you must click on "Ok - accept changes" to return you to the Media Toolbox Unit Selection window:

AmigaOS Media Toolbox Unit Selection Window

At this point, the selected unit will now show as having been "Modified(!)" and the "Save to disk" button will be un-ghosted. Click on the "Save to disk" button to save your changes. Another requester will pop up:

AmigaOS Media Toolbox Unit Selection Window

After all the effort you've gone to you should click on the Yes,save. button.

You can then quit Media Toolbox by clicking on the close gadget at the top left-hand corner, at which point another requester will pop up:

AmigaOS Media Toolbox Unit Selection Window

Unless there is a strong reason why you shouldn't, we recommend you click on "Yes, reboot NOW!". After the reboot your partitions will be available for use.
