How can I do that manually?

But Workbench 3.0 should run with Aros.Rom too.

Method 1 and there is also an example.

Example usage in S:Startup-Sequence: ; Kickstart 3.1.4 has expansion.library V45.  For other Kickstarts, use the appropriate version. Version >NIL: expansion.library 45 If WARN   ; Use the correct Kickstart file path.  If mapping an extended ROM file with Kickstart 1.3, add the appropriate arguments.   C:VampireMap DEVS:Kickstarts/kick.a1200 EndIf

You will need a Kickstart-File for this.

This is my startup-sequence:

  $VER: Startup-Sequence_HardDrive 40.5 (30.12.99)

I want to add the Kickstart for the Amiga 1200-
Can you tell me, where in the startup-sequence I have to add which instruction and I want to prepare the workbench in Winuae from this tutorial:
EXTERNAL LINK  The vapmireMap is in SAGA-Driver. Can I install the Saga-Driver at the point, after I have to install the P96-Driver in Winuae or the driver must me installed after I put the CF-Card in my Apollo V4, and I have to add the VampireMap before?

Sorry, I think, that sounds confused, but  but I hope you understand what I mean.

Thank you!
