Having tried my V2 in the A1000, I see no reason to continue. With only 512k of chipram much is unusable or difficult.

Amiga Love is working on a retool of the Rejuvenator board which expands chip ram in the 1000. Very promising.

  If I am not mistaken, the AGA core for the V4 Firebird will finally fix that limitation along with providing AGA and ECS capabilities to your A1000 .. you should likely end up with 12MB chip like the V4SA has .. a tad more than the rejuvenator can ever provide..

Yes this is correct. With the Firebird you have the option to enable AGA and 12 MB chipmem.
Per default the Firebird will operate as normal Accelerator giving you  500 MB fastmem and RTG, Ethernet and USB and FastIDE. But you can enable the new AGA mode.

So if I get this I can finally have that Ide channel for a cd-rom?

Thats a long ide cable why does V4SA not like long ide cables

As longer the cable, as more problems you get on FastIDE modes.
The IDE-Spec does clearly recommend you to use shorter cables with CF and faster ID modes.
This is not a problem of the V4SA, this is just physics.

Excellent that the ChipRAM can be expanded. I think I found use for a Firebird in my A1000.

Tomorrow the postman wil bring me my Firebird ;) So last days i spend getting as much information as possible, already prepared an CF too
But one thing i dont get clear, will the AGA setting be rememberd after a cold boot?

Hi.

How is this switch to AGA mode being done?

I mean, is there a switch in VControl? Or is it a separate core?

It is one core.
You have in the core some soft switches.
But setting them should be done before loading the Kickstart, so that the Kickstart identifies the system correctly.

I think a good solution will be to store these settings in non volatile memory and to apply them on poweron.

OK. I'm unclear how to change this setting at all right now. Is there some documentation?

  Reading the brieflet included with the Firebird it says there is a special AGA core. I'd assume this is obsolete from what you say.
  But on apollo-computer.com in the download section I find an AGA core.
  So I'm a bit confused.
