JB >> "Older machines are maked on the left side with *1989 COMMODORE
AMIGA 2000 and MADE IN GERMANY […] For these boards the ROM IC must have
Pin 1 connected to Pin 31".
Hmmmm… even Commodore's instruction sheet for the 2.04 ROM was more
detailed.
The A500's with rev 3 & 5 motherboards, needed the wire to signal the
system that the 2.04 Kickstart ROM was a 512K chip instead of the 256K ROM
chip used for 1.2 & 1.3. Later revisions of the A500 & A2000 could detect
the presence of either a 256K or 512K ROM.
I would assume the same is true for the 3.1 ROM, if it is 512K. It will
need the wire for systems that can't detect 512K ROMs without help.

JB >>Make the pin 1-31 connection, plug it in, power up. Nothing. Remove
the pin 1-31 connection, plug it in again, power up. Works.<<
The side affect of having an Amiga that can detect either a 256K or 512K
ROM. These systems get confused by the wire.

JB >>Wonder if I should repartition my hard drive and start over?<<
Yes. To install the WHOLE system you will need more than 2.2-megs of Boot
space. However, you might get away with installing the basics on the boot
partition, and the extras on another partition.
I, myself, have a 10-meg partition just for the Workbench, and any 3rd
party files that with the Workbench (3rd party libraries, devices, fonts,
etc.) So far, I've filled 7-megs of the 10-meg partition, but could
reduce the amount used to 5-megs if I removed 3rd party fonts, patterns,
and pics.
