I own an old PC4. It is still running well. My question to you: Does someone know the jumper settings?????????? I searched for all jumpers on the board and found 12. One of it is pink (JP10). My system only got 1MB of RAM. Now I added 4 more RAM. But in the BIOS they are disabled. How can I activate them?

Hello (1. If I'm in the wrong place - sorry / 2.My English is terrible I know) I own an old PC4. It is still running well. My question to you: Does someone know the jumper settings?????????? I searched for all jumpers on the board and found 12. One of it is pink (JP10). My system only got 1MB of RAM. Now I added 4 more RAM. But in the BIOS they are disabled. How can I activate them? Hope you can help me in that way... :) Regards, Joerg
