So after moving some cards around and making sure the swap jumper is open on my A4000T mediator I decided to try this BigRamPlus once more. Amikit asked me to see what it shows in early startup, and in every ZIII slot it shows as defective. Here is an example picture. Is this a bad card or a bad config? In anycase I am stuck with a board I am not sure works.
The 4000t with mediator is super picky on the card order,it could be you are running out of zorro3 space with the particular order. i will check with a friend who runs a 4000t,i think he uses a zoram but i am not sure.
Can you try it in a A3000 or A4000 and see if it shows ok?
