Sorry to revive this thread. I have no real problem using my BigRAMplus in my A4000 with Mediator 4000Di MK III (3,3v) being recognised in both AOS 3.x and AOS 4.1. However it is not running all too stable in AOS3.x. So now I'm wondering (amongst other things) what is the Mediator jumper settings needed.
I have:
A4000D
2Chip + 16 FastRAM
Buster 11
CSPPC + 128 MB
Mediator 4000Di
Voodoo 3
PCI NIC
Highway USB
BigRAMPlus 256 MB
If I follow this guide
https://mediators.github.io my mediator jumpers would be:
Master: Closed
Winsize: Open (since my voodoo has much less than 256 MB)
Swap: Closed since the BigRAMplus supports DMA, correct?
