Gayle Hardware Registers

[bluea]

Hello, is there any information about the Gayle hardware registers?

I want to implement an AT-IDE interface. I already know the IDE-registers at 0xda0000 and 0xda1000 (0xdd2020 and 0xdd3020 an A4000). But an A1200 Kickstart 40.70 is ignoring the idedrive at all.

I think I need to implement some "configuration registers" at 0xda800, 0xda900, 0xdaa00 and 0xdab00...
But after extensive search I did not find any definitions about them. Register addresses and bit-allocations.

Is there somebody here who can help??

Thanks in advance!

Thank you Doobrey!
Yes, you are right. I use 40.68. Sorry, was typing too fast. 40.70 ist not working till now... if I start the system with 40.70 it is waiting at dark grey screen in a loop. I dont know what is missing. And because of that I use th A1200 Kickstart.

I found that sourcees for linux. But there are only the IDE registers listed. I implemented them. But the Kickstart checks first if Gayle is available. So I have to make him "visible" in memory.

Even on the Amiga Developer CD there is no register summary :-(
