Cutting / soldering jumpers and moving drive id dip switches have to do with the old 1540/1541 drives for the 8-bit Commodores! The Amiga's drive chain is very different to the old commodore serial bus.
The Amiga's floppy drive daisy chaining works by always having the next DS signal at the same pin (and the ones following it after that) at the external floppy connector.
The external drives just move the next DS signals one pin down at their respective external connectors.
DS 1 2 and 3 are present on the Amiga's ext floppy connector
DS 2 and 3 are present on the first ext floppy drive's daisy chain connector, etc.
Commodore warned against daisy chaining A1010s when connected to an A500, as they draw a lot of current. The slimline aftermarket drives consume less and it's safe to add three of those.
