| Jumper# | Description | DEFAULT |
| #1 |
This Jumper defines how much graphicsmemory the PicassoIV will use in ZorroII mode. If the jumper is closed
the card will use 2MB; if it`s opened it will use 4MB. If the card will be used in a A2000 with a allready installed Turboboard reserving most of the expansion memory, the restriction to 2MB can be usefull. If you are using the card in Zorro III mode the jumper should be usually opened. |
