Ice Drake IDE + A1200 IDE - Making Both Work

Hi
I just want to clarify - will the on-board IDE port on the A1200 still function once the Ice Drake is installed?

I'm assuming the Ice Drake IDE ports become the bootable interface once installed, but I hope the on-board interface is still operational, even if no longer bootable.

In my Checkmate case I have two SSD hard drives and a CD Drive I want to attach. Ideally, I'd like to put the hard drives on the fast IDE interface on the Ice Drake (either as Master and Slave on one channel, or Master/Master across the two channels) and stick the CD-Rom on the internal IDE.

Anyway - any clarification on this would be greatly appreciated. Thanks

No not at the moment. I think the same thing with the pcmcia slot too.

PCMCIA works fine

Handy that the PCMCIA still works, but extremely frustrating that the on-board A1200 IDE interface doesn’t work.

I’m assuming I can at least connect four devices to the two IDE ports on the Ice Drake (Master/Slave on each channel/ connector)?

The ICE-DRAKE IDE overlays the IDE of the mainboard.
This is well announced and public information.
You will have read this in the announcement. 

This has several advantages:
a) Every OS does support the controller out of the box.
This including Amiga OS, Atari OS, and Aros. 

b) Also the IDE ports of the ICEDRAKE have IDE DMA capabilities
(not enabled in driver yet) so it makes a lot sense to use these advanced ports instead the old mainboard port.

The Icedrake has 2 Fast IDE hardware ports (44 and 40pin).
With 2 devices per port this gives max 4 devices.
Amiga OS per default will only support 2 devices.
With "multiport" patch you can use 4 devices.

In addition, the IDE port of the ICEDRAKE is really very fast.
I've never seen anything like that on an Amiga. Not even with a Blizzard 060!
Really very cool! :)

No, I can say with 100% certainty that I have never seen or read any such announcement. Can you provide a link to this announcement please?

Agreed - Mapping over the top of the on-board interface does make sense in terms of ensuring boot compatibility for the Ice Drake ports with AmigaOS etc. But it is still limiting. Would have been helpful to have both and allowed for extra drives.

That is good news that the Ice Drake ports will handle 4 IDE devices - we can work with this. What multiport patch is needed - IDEfix97 or something else? Assuming AmigaOS 3.2 won’t need patching as it already has a patched driver for 4-port adapters on the main board.

I read that when you plug more IDE devices the controller slows down to the slowest one.
Anyway i cannot successfully plug the external IDE CD-Rom, my amiga dosen't even boot with a CD rom plugged to the second IDE port of the Icedrake!

Off topic, but related , does the IDE port on the Vampire (V1200) support multiple devices on the same ribbon?

It’s an Amiga at the end of the day - drive speed is no big deal. Having multiple storage options connected other than unnecessarily expensive CF cards is, however, very helpful.

So, not well announced at all then.
