The Kickstart ROM Replacement (Phase I) bounty has been assigned to Jason McMullan. The bounty aims at enabling AROS to build for m68k Amiga system. This part does not include binary compatibility with existing m68k Amiga applications. The deadline for this work is 31st December 2010.

Jason has been working behind the sceenes for some time and now he has started adding compatibility changes directly to AROS source code tree. For the time beeing he built the kernel and now is working on getting OCS driver implemented.

The bounty details and donate page can be found here

This is great news. Not complaining, just asking, isn't this the second or third time this bounty has been assigned? Hopefully this time Jason will have better luck completing it.

Good luck Jason and thanks! Aros on 68k would be awesome!

Awesome?

A new kickstart will be interesting for amigaos 3.x, i dont see aros running under 030 and aga.

More details from the AROS dev mailing list:

Finally, after 3 weeks, first light on my m68k port of AROS to m68k-amiga.

Doesn't work, crashes pretty soon, but I have gotten path the 'compile it',
'compile it with Amiga ABI', and 'get into Exec Init' phases. Very happy.

Other than the giant pile of AROS patches I'll be committing as soon as I
get SVN access, I also have a (tiny) GCC patch that is needed to match
the Amiga ABI, and a e-uae patch to enable serial.

Against current AROS tip, gcc v4.5.1, and e-uae tip:

http://www.evillabs.net/AROS/AROS-20...09-m68k.tar.gz

Also includes a pre-compiled A1200 ROM image, which boots
(and crashes).

And more news:

- Jason McMullan has now SVN access to the AROS tree
- ABI issues appear to be fixed (native)
- library init successful up to graphics.library and intuition.library
- working on OCS single-plane HIDD

Hmm... I don't wish to appear to be too negative, but what advantage would you get from running AROS on a 'classic' Amiga, over WB3.1?

Wouldn't it be better to concentrate more effort to improving AROS drivers and compatibility with x86 systems?

Just wondering...

Cheers,

Mike.

People need to stop thinking that what is to them "pointless" things to work on will somehow take away development from other parts of AROS! this is one guy who wanted to do this particular bounty, if he didnt work on this one, chances are he wouldn't work on anything else in AROS either, and this is true with a lot of bountys and other AROS related work. People come or join in to work on stuff they want and quite a few stop contributing to AROS once they reached they're goals whatever they may be.

Benefits would be:

1. Working "out of box" Amiga clones, wihout needing permission from anyone
a) minimig
b) natami
c)...
* Minimig could be mainstream product with this


2. No need to build custom kickstart yourself
a) CD-rom boot, maybe rtg support build in
b) Possibility to manufacture and sell replacements kickstarts

3. Future developement
a) Projects like natami would get big benefit of this and theory maybe even coldfire accelerators.
b) ...

4.

[orb85750]

....benefits once the binary compatibility phase is completed too, right?

Then this idea isnt for real amigas, then another way to add to, mos, os4 and aros

[Franko]

Finally took the time to find out what on earth AROS was all about, basically to me it's just like MorphOS, WarpOS or OS4.x.

After all the posts I've seen here on Amiga.org with people praising AROS, I can only say that I'm kinda disappointed, was hoping to find that it was something that would be useful to me on my various A1200s, or have I missed the point about AROS...

[Belial6]

Besides giving MiniMig and the like a compatible OS to run out of the box, it would also allow AROS x86 to be backward compatible with original Amiga software. With the UAE integration that has happenened, 68k software running on AROS x86 looks pretty good. The achillies heal of this it the fact that to legally run this you have to buy a commercial product. So, AROS x86 is backward compatible, but the backward compatibility is not open source like the rest of the OS.

If it helps you appreciate it, just think of it as Amiga68k.hidd.

Ignore....double post.

No, it's for real Amigas. The point is to run AROS in 68k Amigas without having to rely on the Commodore licensed ROMs and to have an AROS user interface.

Unless I'm completely off the mark (it's been years since I help push this bounty into reality), the initial reason for this is to move forward on a FOSS kickstart ROM. Once someone picks up and completes Phase2, then there will be zero need for any commercial software (kickstart or WB) in UAE.

Can this be ported to individual Amigas for native running? With alot of work, I don't see why it would be impossible. AROS can be the life line for Amiga68K as future kickstart/wb upgrades. Life for your old friend may not have to stop at 3.9, just takes a huge amount of work is all. ;-)

And to take advantage of a system that is being still developed, and has some neat modern features that AmigaOS for classics never had.
