For the ROM-based installation process, you first need to copy the new system component to your system. For that, insert any of the modules disks into the first disk drive, then select "Execute command" from the Workbench menu, and enter the following command:
copy df0:libs/intuition-v45.library to LIBS:intuition.library clone
In case you installed from a physical 3.1.4. ROM, LoadModule has to be installed manually. For that, download the archive
http://aminet.net/util/boot/LoadModule.lha
from Aminet and copy the LoadModule command from this archive into the C directory of your boot disk.
The Startup-sequence of your system requires a modification. To perform this installation, select "Execute command" once more from the Workbench menu, and enter the following command:
Ed S:Startup-sequence
A window containing your Startup-sequence will open. The first lines on the screen should read as follows:
If Exists C:LoadModule
C:Version exec.library version 46 >NIL:
If Warn
C:LoadModule ROMUPDATE
EndIf
EndIf
Replace them with the following:
C:LoadModule ROMUPDATE
Then save the result back to disk by pressing the ESC key, then the X key, then press return. Then reboot.
