I'm working very hard since many years on a new kickass Kickstart !

Anyway, only the beginning : the real work just started with this beta 1...

A quick video : https://www.youtube.com/watch?v=UiJM-6RPRCk


More informations here : http://leblogdecosmos.blogspot.fr/p/kickstart-391-eng.html

@CosmosUnivers

I started this new thread : if you have any ideas for improving the Kick, please write here !

@CosmosUnivers

What!!, i never heard of this before, and why haven't any done this a long time ago?

this must be a lot of work, and i hope you succeed releasing it.

I started with individual libraries : now, it's the whole Kickstart...

The ROM space available in the A500 and up memmory map in the supplied manual, shows a 256k used, with 256k, then 512k, then 1 Meg reserved, giving a total space of 2 Meg in 24 bit space reserved for ROM. But, Fast RAM mapping is almost always used these days, so are you going to use a 64k initialise and extraction block, so that the 2 Meg ROM can actually be closer to 5 Meg uncomporessed code?

Or, are you going to go the whole hog, and use PC BIOS chips at 33 Mhz, on a small DIP board with a microcontroller for interfacing and possibly CPU emulation at most extreme?

Can a Raspberry Pi 40 pin GPIO port map in pins, and speed, to the ROM socket? Use a Pi as a ROM?

I tried 2 Mb Rom on my A600 many years ago and it's working fine...

But on my A1200, I cannot get any boot... If someone know why, please talk to me !


DIP Eprom 42 pins support 2 Mb, no need others ICs...

@CosmosUnivers

This would be very useful for the GBA1000 Boards.

@CosmosUnivers

Will be available for purchase?

@AmigaMania

It will probably be free for us to download and patch our roms and create them ourselves if we behave :P

@CosmosUnivers

With a 2 MR rom you're overlaying the Z2 configuration space. There's autoconfig memory in your 1200?

@CosmosUnivers

Did you resolve the problem with members at EAB selling your work? Who were they, so I know to avoid them in the future?

I have recently posted messages about the need for updated Kickstart & Workbench for Amiga 68k systems, emulation, and FPGA accelerators, or clones.

If we will have new FPGA accelerators & stand alone clone systems that have much higher performance 680x0 soft-core CPU's in the near future available for sale to many users, it would be very nice to see a new version of Kickstart & Workbench that can take full advantage of this increased speed.

Hopefully, we will see actual products running improved AmigaOS for 68k next year, and not just more talk and ideas and claims.

Thanks for your work on this, I look forward to great things next year.

I checked with a naked 1200 : why it's working on A600 and not on A1200 ?


@amigadave

No problem to solve : after the guy on EAB, I decided to stop any release... I won't change my mind : it's over now...


I can add what you want into this new Kickstart...

Okay, I am confused now. You are posting here about work that you are continuing to do on something you call Kickstart 3.9.1. What was it that you were going to release before what happened on EAB? Some other project?

Edit: I also would still like to know who it was at EAB that was selling your work, so I can avoid them in the future.

@CosmosUnivers

What do you read from 0x00e00000 to 0x00efffff when using a 1MB or smaller ROM?

And is it the physical size of the chip or the actual addresses USED we're talking about?

@olegil

512 Kb Kick : $F8
1 Mb Kick : $E0 & $F8
2 Mb Kick (A600) : $A8 & $B0 &E0 & $F8


I used a 2 Mb eprom of course !

@CosmosUnivers

Ah. The mapping isn't very straight forward, then. Someone with an oscilloscope might be able to do an access to $A8 and $B0 on an A1200 and see if the _ROMEN signal goes low at all (obviously while soft-kicking).

But A8 and B0 are in the Z2 extended IO space, which might explain why they're treated differently in the AA-Gayle.

This is documented here:
http://amigadev.elowar.com/read/ADCD_2.1/Hardware_Manual_guide/node0293.html

Which is a sub-chapter of "what's the difference between A3000 and A2000 Z2 implementations" (my interpretation)

So I would think this is as expected. But I haven't verified it, and I haven't even checked if the A3000 uses the same Gayle as the A1200. I just know the A1200 and A600 Gayles are not the same chip.

@olegil

Hmm. The answer to the last paragraph is that A3000 uses Gary (like the A500), so I'm not entirely certain what to make of anything here. In an A3000 a 2MB ROM would MOST certainly crash something very badly, but whether the A1200 Gayle is supposed to prevent this or something I do not know.

Beta 2 :

Now 1 Mb with two blocs of 512 Kb
Added workbench.library 45.135
Added icon.library by Peter Keunecke
exec.library a little bit enhanced
Added a decrunch subroutine
All patch from SetPatch included
Now SetPatch is only required for loading the 68040/68060.library
ram-handler 44.23 removed
shell 45.27 removed
Put back ram-handler 39.4 from the Kickstart 3.1
Put back shell 40.2 from the Kickstart 3.1
