Amiga OS 4.1 Classic generically will scan for Zorro 3 memory and use it as swap memory. So as long as the Zorro 3 memory card conforms to proper specs, in theory any Zorro 3 memory card (including WinUAE which can add Zorro 3 memory!) will work. During OS 4.1 Classic testing we only had ZorRAM and a DKB 3128 for testing so that was all that was mentioned. I don't think the BigRAM was available yet.
