Hi
> I wondered if those few lines BEFORE it were enough for a functioning ram-handler !
You are running Kickstart/Workbench 1.3 ? The code for the RAM-handler is found in the "l" directory of your Workbench-disk. An entry in the "so called" DOSList addressing this handler is created during system-startup, no way to suppress this (the according code is stored in the Kickstart ROM :-)).
The handlers code itself is loaded during the first access to the RAM-disk, i.e. the first time the volume "RAM:" is accessed (usually by the commandline "Assign T: RAM:T" in the "startup-sequence").
If you create a startup-sequence without any reference to "RAM:". There will not be a "RAM-disk" icon on your Workbench screen, but it will occure at that moment you type something like "dir RAM:" in a CLI (or any application tries to access "RAM:").
If you need maximum memory, create an empty disk and "initialize" it, so it contains a boot-block and use this empty disk for booting. You will get the initial CLI and nothing else.
I recommend you to have a look to ebay and buy a memory expansion for a few bucks. There are a lot of games that also will benefit from more than 1MB ram.

EDIT - Do you have additonal disk-drives connected to your Amiga ? Remove them, every additional disk-drive costs at least 50 Kb memory.
EDIT-2 - I don't think you will get 960+ KB memory, whatever you are doing, there are several structures according to the OS that are created by the code in the Kickstart ROM during system startup, you can't suppress this, and I think this uses more than 50Kb.
