Amiga & AROS "In a previous item, we described how the AmigaOS4.0 memory system works in terms of managing memory allocations from the top. However, there is more to allocating memory than that. The object caches of course work on memory that has already been mapped into the virtual memory space. But both the virtual address ranges, as well as the physical memory has to come from a source, too."

Re: great OS without hardware

It has been rehashed time and time again within the Amiga community - and of course you're excused for not knowing about it. But it's really quite simple: It won't happen. At least not in the foreseeable future.

The OS is big endian and it would take a lot of work to convert everything to little endian. Besides that the markets that are alluring for the development team (embedded) tends to favour PPC chips, so it makes sense to have a PPC development platform. It's probably more realistic to aim at businesses with specific needs and sell them what they need rather than try to recapture the desktop market, which has high expectations for what a desktop OS needs today. Sure, AmigaOS 4 lives up to a lot of it and in some areas it still offers features sadly lacking in other systems. But these days you're supposed to deliver a system that plays dvds, shows flash, has java, has a full office suite etc out of the box.

There are probably a lot of users that will be happy with less, but most won't. One of the strengths of AmigaOS 4 is the low footprint, efficiency and relative elegance. That makes it an interesting product for embedded markets (even though some will go with Linux, QNX or other solutions). It's also a great hobbyist computer and it'll also do most of your tasks like some word processing, DTP, graphics, mail, chatting and so on. But it's not for the mainstream market yet. Not even close - as much as I love it (heck, typing from OS4 right now).

I don't really agree with the usual argument that by moving to x86, you're effectively going up against Windows, because you already are. But the advantages of being PPC - and not least the economic realities of OS4 development - mean that it's not going to a different CPU family than PPC any time soon. What we can hope for, though, is some cheap hardware for people that want to try it out. It's not impossible - it just hasn't happened yet.

well, you have some valids arguments, 've not said it's easy to do. OS4 certainly have some great value for people like you, but I prefer to support an OS I can try like Haiku.

btw, OS4 is targeting desktop computing, I don't think it is well suited for embedded systems.

Yes, it is also targeting desktop computing, but that is not what will bring the bread and butter for the developers.
I think the closest to desktop computing we will see in the immediate future besides hobbyists is minimalistic terminals with clients for remote access - for instance there is an excellent RDesktop port for OS4.

But what percentages can be won from desktop adoption in the short run will hardly pay for continued development. Finding OEMs that are interested in solutions like this and selling components where it makes sense (such as the licensing of 3D driver technology which was done in March this year) is most likely what will keep development going, till the OS reaches a level where it can comfortably accomodate the average computer user.

Not according to who's making the OS:

I quote: "Contrary to x86, PowerPC are being used in embedded applications. We do have a PDA running AmigaOS to begin with (unfortunately I don't think I am allowed to show the video I recorded), and there are concrete plans (which I surely cannot comment on).".

As for the availability of AOS4 to the masses, here's another relevant quote from one of the guys who's making the OS:

"There are no customers outside the grounp of Amiga-fanatics. Name me a few good reasons why a MacOS or Windows user should use AmigaOS, regardless of the hardware platform? I'm sorry, but I am not arrogant enough to think that AmigaOS (or any clone, for the matter) could go against any mainstream OS. It's an OS for Amiga hobbyists, and it will take a long time and a lot of work to get it to any other state. So, pray, how would you like to attract masses of new users outside the Amiga market?"

Looks like there's no much hope for a widespread adoption of AOS4, by the very own words of who's making the OS.

The announcement on OSNews is generic and it is aimed for those who care.

I don't understand why people like you who are not interested in Amiga come and make silly statements about AmigaOS.

You love haiku, you said you can try Haiku on your platform? Then use it.

But if you are curious and if you want to look to something similar to AmigaOS 4.0 on your X86 platform then try AROS.

Here the latest live CD distro named AROSMAX (no need of installing it, boot the CD and run it) is here:


1) AROS it is an implementation of AmigaOS 3.1. It has not all advanced features of AOS 4.0

2) AROS it is still in development and lacks of many things and lacks of many software. Just try it AS IS...

It is a very simple experiencing, but if it will enlighten you it could show you how beautyful it is a small footprint OS, with very lower resource consumption, and with a few system directories with all things in their place.
No complicated as Linux, no messy as Windows.
