AmigaOne - SLB - Upgrading SLB

Periodically it may be necessary to upgrade the SLB as a result of U-Boot, AmigaOS or other software upgrades. This step will typically be requested within the installation/setup instructions but it won't tell you how to do it. It will probably just say that it needs to be done first.

The SLB image is stored in the SYS:L drawer and may be called "slb_v2." but it could be called anything, such as "slb.v2", "slb.v2_11", "slb.v2_nolinux", "slb.v2_nosfs", or whatever. Amiga Auckland change the name to "slb.v2.x.y" where x and y correspond to the version numbers specified in the release notes that are supplied with the slb distribution.

Once it has been saved to the SYS:L drawer you are ready to update the system with it. For this you must use Media Toolbox which you will find in the SYS:Tools drawer, as shown below:

AmigaOS Tools Drawer showing Media Toolbox

Double click on the icon to run it, at which point the following window will open:

AmigaOS Media Toolbox Device Selection Window

Check Program mode near the bottom of the window and if it says "Expert", change it to "Normal" before selecting the device (normally a1ide.device) that contains the bootable disk containing your operating systems by clicking on it, and finally click on the Start button which will display the Media Toolbox Unit Selection window:

AmigaOS Media Toolbox Unit Selection Window

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, buttons below the unit list will become un-ghosted as shown below:

AmigaOS Media Toolbox Unit Selection Window

The next step is to click on the Edit RDB/Reinstall button. Another screen will appear with options that can seriously impact your system if used at this time, so take care!

AmigaOS Media Toolbox RDB/disk geometry editing

The button you need is labelled Install AmigaOne booter and is on the left-hand side of the screen about two-thirds of the way down. When you click on this a requester will appear and Drawer should already point to the SYS:L/ drawer as shown below:

AmigaOS Media Toolbox SLB Selection Requester

Select the name of the new SLB file from the list and click on Ok.

You will now be back at the previous screen, and the name of the file just selected should appear in the box on the right-hand side of the screen labelled "Installed AmigaOne booter:", even though it hasn't quite happened yet.

AmigaOS Media Toolbox SLB Accept Changes

The final step is to click on the Ok - accept changes button to update the SLB file on disk. This will return you to the original Media Toolbox window.

AmigaOS Media Toolbox Unit Selection Window

You can now quit Media Toolbox by clicking on the close button at the top left-hand corner.

Congratulations, you have successfully updated the SLB.
