OK, so i removed E123C & E125C, now the machine comes up but only after 2 minutes of a black screen. (I know this is not a fix for 1D1 motherboards but I'm desperate!)

By holding down the two mouse buttons it shows no cards installed.

 Totally normal, A1200 just show defective boards or accelerators.

If I boot up workbench the fast ram shows up and it shows that the o4o is installed (typing CPU in shell).

But the thing is everytime soft reset or cold power cycle the machine always takes about 2 minutes boot up...
 

 Substitute the caps around the board (only the electrolytics, of course). Sounds like some of them are bad!

(I never xfered the 3.1 chips from my dead motherboard, was afraid since I don't know what is wrong with the old one, I may just order a new set from amigakit)

Is it because I am running this card with 3.0 Kickstart?

 May be!

Will this card work better with 3.1 Kickstart?

 Probably.

 Just one question/affirmation: ROM or EPROM chips don't burn anything, even if they are defective. In the worst situation, the Amiga simply refuse to boot.

 When I fixed the Mediator passtrough, I discovered a pin who was slightly out.

 This pin was one (of 2) responsible for the non-functional Mediator. The other was simply broken down.

 What to do?

 Whit a SMD rework solder station, I take the 1200 connector out of the passtrough, take the two problematic pins and replace them for two in the upmost pins of the very same connector, then re-solder it to the passtrough.

 Now my Mediator runs like a charm.
