Hi There,
I have two internal floppies I want to install in a working Amiga 2000 with Kickstart 1.3.
Both floppies were once DF0 on two separate A2000 that only had 1 floppy.
What's the jumper settings when installing both floppies into the same A2000 as DF0 and DF1? Does anybody know?

See this picture (http://home.wanadoo.nl/leof/A2000Floppies.jpg) taken from two A2000 drives. Although they are both Chinon FB-354 Rev.A drives, they've got different jumper blocks. The upper one is the DF1:, the lower is DF0:. Hope this gets you going.
If you have trouble using the floppy cable: see this thread (http://www.amiga.org/forums/showthread.php?t=16849).

and don't forget to set the jumper on the motherboard...

Hi leofoe,
Thanks for the picture, this got me going. Essentially, the DF0 jumper stays the same as if there was only one internal floppy and DF1 jumper sits on the two right pins instead. The upper row of pins seen on the picture in one of the drives is not used at all.
As mentioned in the other response by Darrin, I also had to close jumper J301 on the motherboard. Page A-23 of the Amiga 2000 manual says this jumper has to be closed in order for the Amiga to recognize an ID bit stream from each floppy. This is normally not necessary when there's only one internal floppy. Found an extra jumper from a busted pc motherboard.
Everything works now. I let it boot normally from the hard drive first, then I inserted disks one by one in each floppy. After that, I shut down and inserted WB in DF0 and Extras in DF1 and re-booted.
All drives light up when fed. Everything worked just great.
