Ok since few days A500 is started with Vampire500, so next logical step was to add IDE controller and that was simple task so code is written in 10 minutes. Then I realized that there is no autoboot option and that I need to solve 2 additional wires /OVR and /INT2.
For OVR it was easy task and internal DTACK was created but it seems that Gayle manual is just not enough for me to understand generation of INT2. So can someone in simple words explain to me those relations between DA8000, DA9000 and DAA000 and bit 15. And what IRQ request from IDE has to do with them, he needs to activate something.
