Installing GS/OS®


 

What You Need


Before proceeding, make sure you have the following items within reach:

  • the GS/OS installer disks (disks 1 thru 6)

    Please refer to the previous tutorial to learn more about how to download the GS/OS system disks.

  • a target disk image where GS/OS will be installed onto

    We recommend you to choose a size of 20Mb for the system disk image. If you're short of disk space, 3 Mb are sufficient as well, but you might run out of space when adding fonts or system utilities.

  • you need copy of Bernie including the Apple IIgs ROM

    If you are using an unregistered copy of Bernie, be sure Bernie has just been started, otherwise the installation process may be interrupt by Bernie's 30 minutes session limit and leave an incomplete system installation behind.

Mount The GS/OS Installer Disks


Unlike with a real IIgs, you can mount all 6 installer disks at once. This frees you from swapping disks during the installation process.

Mount the first installer disk ("Disk 1 of 7-Install"), then the second, and so forth.

Mount The Target Disk


Lastly, mount the disk image where you would like to install GS/OS onto.

Check Bernie Settings


Now open the Setup menu in Bernie's menu bar and make sure that the item "Low-Level Disk Support" is deselected. It must not have a check mark to the left.

If "Low-Level Disk Support" is selected, choose it once to toggle its state.

Reboot The IIgs


With all the disk images mounted properly and Low-Level Disk Support disabled, you're settled for a GS/OS install. Reboot the emulated Apple IIgs by choosing "Reset" from Bernie's Setup menu.

Start Custom Install


After some time, the Installer is loaded and the main window is shown. Push the "Customize" button.

Choose Target Disk


If the text at the top ("Disk to update:") is not pointing at the target disk, push the "Disk" button (lower right corner in the window) until its name appears. Then, choose the option "System 6: hard Disk or FDHD" from the list of choices and push the "Install" button.

Wait...


The Installer will now write the required files to the target disk. This process may take a while.

Done!


Congratulations, you now have a fully functional GS/OS startup disk. You might want to consider making this disk your default startup disk in Bernie so that every time you launch Bernie, this disk will be mounted automatically.
