I did a step by step guide on how to add ehide.device to a 3.1 rom, it is some where on here
But a guy over on A1K made a OS 3.2.1 patcher, where you just need a genuine 3.2.1 rom , either from your hardware using say `Transrom` or getting it from `Amiga Forever` if you have the genuine disk.
Then run it through the patcher and it will spit out two Hi and Lo files that you just then byteswap and can burn to eproms
