I'm pretty sure that one of the options can specify what ram to use, perhaps flags.
As for the 8MB jumper, I believe it is there in case you do not find any 2MB module to use for chip, and want to use a 4MB or 8MB module instead. Only 2MB will show up in the system, regardless.

Hi,
Nope, dont even think of changing that jumper to the 8 Meg setting.
It has nothing to do with using SIMMs.
It was part of a motherboard development which never happened.
See
http://wonkity.com/~wblock/a4000hard/mbjumper.html"J213: Chip RAM: 2M or 8M
1-2 Closed: 2M Chip RAM (default).
2-3 Closed: 8M Chip RAM. This option was apparently for use with the never-released AAA chip set, and won't work in a normal A4000."
