    Even more importantly, from that same Darwin FAQ:

    Darwin is the core of MacOS X.

    This is why this is such a big deal. The fact that it runs on VirtualPC without modifying that software application (unlike, say, Windows Me) means that a vast majority of x86 processors out there today can run Darwin. And if they can run Darwin, the core of MacOS X, they're much much closer to being able to run MacOS X itself.

    So be happy. The open source community has just scored another coup. :-)

    You won't see it for a while, but my guess is that it'll happen.

    Right now Apple's cash cow is their hardware. And until the majority of apps are re-written to be native OS X code (a.k.a. Cocoa), as opposed to "optimized MacOS Classic code" (a.k.a. Carbon), you won't see any public push from Apple to get OS X running on Intel. I'll bet they're working on it, but way, way, way behind the scenes, in case Motorola can't deliver the faster G4s like they said they could. (IBM can do it, but the G4 is Mot's baby, and they're the ones saying "no".)

    If Apple would release OS X for X86 before the apps are fully ramped up and Apple has licensing in place with PC vendors, it would be a disaster. The bottom would fall out of Apple's hardware sales, the apps wouldn't be there to make the masses switch platforms (especially corporate clients), and Apple would last about 6 months.

    I say they'll keep churning along like they're doing now with PPC hardware, wait a couple years until all the major apps are OS X native, then strike up an OS X for x86 licensing deal with clone manufacturers. Assuming the current clock speed hurdles for the PPC chip are overcome, Apple will retain the "high end" with the PPC, and let clone manufacturers churn out the low-end. Why? Apple will always want to "make the whole widget". And I for one think they should.

    The OS X you saw, or probably read about, was PRE-BETA. Are you kidding me? You are judging Alpha software for speed? I read that the beta is nuch faster than DP4 and I ran DP4 and the speed was fine. The reason why Apple is push dual-processor Macs to get a 1GHz machine out there. But regardless a 500MHz G4 runs as fast as a 700-800MHz PIII.

  4. Of course... by talonyx · · Score: 3

    It's an x86 emulator. Darwin for x86 is an x86 program. Of course it works! If it _didn't_, THEN this would be interesting news.

    This is like saying, "Super Mario World worked when CmdrTaco tried it on SNES9x for Linux!"

    Of course it worked!

    Now, it would be interesting if there were followups as to the chances of OSX for x86, etc, etc. But, why would there be? And even if there was, why would any of you Linux junkies want to go out and pay for it? Apple has always made the cash by selling the hardware too.

    That's enough outta me.

  5. BeOS? by 2quam4 · · Score: 3

    Does the information concerning Darwin for x86 remind anyone else of BeOS? Too bad Sun Office has not been ported to BeOS and Be has concentrated all their resources on BeIA, it seemed for awhile there (about 1 1/2 years ago?) BeOS had a chance and could have been up to speed with Linux.
    I'm curious about the Be communities "feelings" about Darwin.

    It seems that from the Darwin FAQ that...

    "Most of the Darwin code is platform independent, and some of the platform-specific code includes some support for Intel processor-based systems. Darwin 1.0 has been compiled (on a PowerPC-based Macintosh system) for both Intel and PowerPC platforms, but the Intel support is very rudimentary. (For example, there's no installer, and it works only on one specific configuration.) We are working with the Darwin community to make Darwin a viable operating system for the Intel platform."

    Darwin is still in its earliest stages on x86. If you miss the early days of Linux and *BSD, you might enjoy helping get Darwin going.

    If you want to try Darwin for yourself, you'll need

    1. A recent PC (440BX motherboards seem to work; 440FX motherboards don't)
    2. A video card that has a VESA 2.0 compliant BIOS (ATI Rage 128, ATI Rage Pro, and Diamond Stealth III S500 are known to work; the ATI Mach64 GX and the simulated video provided by vmware are known not to)
    3. A disk with about 450 MB free (and don't try using the end of a huge disk -- that won't work)
    4. A fast Internet connection
    5. An Intel i82559 network card if you want 'net connectivity (e.g., Intel EtherExpress Pro/100+ Management card)

    Once you have that hardware, you need to download two images: one for a partition of type AB (20 KB compressed) and one for a partition of type A8 (about 100 MB compressed). Create appropriately sized partitions on your disk (945 blocks and 920304 blocks respectively), and uncompress the images onto those partitions (I used primary partitions; extended partitions might work, too) and try to boot. You can either use lilo, or download a Darwin boot sector.

    If you can boot Darwin, then you can begin to explore. If you like to hack on a new OS, or would like to see how Apple's idea of Mach (monolithic kernel) differs from that of the Hurd (microkernel), or even if you'd just like to see things done a different way (e.g., dyld vs. ld.so, netinfo vs. NIS, IOKit vs. ????, etc.), Darwin can be pretty interesting.

    For more information on on Darwin, check out Darwinfo or Apple's darwin-devel mailing list.

      Where do you get the idea that mach is a monolithic kernel? Mach is a microkernel, albeit a very outdated one. HURD is not a microkernel. HURD is a set of user space servers that run on top of a microkernel, namely the aforementioned mach. Darwin is essentially FreeBSD 3.x running on top of mach.

      This all makes me wonder. FreeBSD runs on x86, then Apple comes along and ports it to the PPC. Then they release it as open source and a bunch of hackers start porting it to the x86. Is there really an advantage to having a BSD running on mach? Especially since mach is notoriously slow. Why?
