Some facts about 10a222

Known facts is:

1) most userspace apps is 32/64-bits now, except safari and itunes

2) vanila kernel works on Core i7

3) there is a lot of 32/64-bit drivers now,  like ati drivers, but still some 32-bit only drivers, like nvidia drivers and atheros.

4) there is completly new framebuffer system for ati cards, one unified framebuffer kexts with plugins for specific models(they called ATIXXXXController.kext, XXXX is a card family)

5) ati 2600 and 3800 cards doesnt work with hardware acceleration(qe/ci/gl) on hacks

6) nvidia drivers support (in theory) new geforce gtx260/280 cards

this list is not complete.

    Thank you.

    What does this mean for the ATI 4800 series? Will the ATIXXXXController.kext give me some basic functionality?

    I’ve got a HD 4870 and right now I’m restricted to using my old CRT since my widescreen flatpanel isn’t 4:3 aspect ratio.

    I’d be willing to install the beta if I got better support for my card.

    Any news of if/when a driver for the 4800 series will be released?

    Great to here the i7 is fully supported. Any chance you’ll release your new version of pc_efi to support the 10a222 build?

    The 4800 series cards are supported in Snow Leopard. I’m pretty positive I saw a post showing off a 4870 x2. 🙂

  7. January 21st, 2009 | 2:29 pm

    Damn…I wish Snow Leopard would come out earlier so I can use my 4850!

    Strange, any idea about the reason why HD2xxx and 38xx series don´t have hardware acceleration? I guess real MacPro does not have that problem?

    What device-IDs for graphic cards is there? 🙂

  10. January 22nd, 2009 | 12:14 am

    I have my card working in Leopard, so I know it works, but is it actually supported in Snow Leopard? Are there actual drivers that will give me hardware acceleration?

    I’m installing 10a222 today, so I’ll post the results later.

    Hey were do you get the 64-bit kexts like dsmos and disabler or know of anyway to convert the 32-bit kexts to 64-bit? Because i can’t boot Snow Leopard with 32-bit kexts and PCEFI v9 Can any one point me in the right direction please it would be much appreciated. x

    i didn’t write that for fun so you could just delete it it wouldn’t take you 2 seconds to answer me and point me in the right direction!

    2) vanila kernel works on Core i7
    What this mean ? The older Core 2 Quad Q6600 not work with Snow leopard (vanilla kernel) ?

  14. January 23rd, 2009 | 2:07 am

    Can’t get Snow Leopard installed. Anyone know of a bootloader that will work with build 10a222? Can’t test it until then.

    EFI9 does on my c2d rig …

    installed from leo with a modified osinstall.mpkg (in order to use a MBR disk) then booting with a “special” kernel & chameleon 12 (some usual .kexts …)

    very buggy so far.

    there is version of v9 to support 10a222 vanila kernel, but i dotn feel like releasing it

  17. January 23rd, 2009 | 10:11 pm

    I tried to update 10.5.6 with 10.6 server but it won´t boot after that it just stopped with the cursor on a grey background.

    I also wont recommend to use it on a working system cuz its a developer preview.

    I also don´t see the point in netkas releasing a working bootloader for it because there is no real use for it yet. it´s still not really clear how the final system will behave itself.

    just my 2 cents

    oh go on mate, why not?

    maybe when the new build is released, you could release the v9 for this one?

    This seems good but it won’t be long before apple release a is for normal pc most of the works been done by netkas. Also why do you want to allow us to test snow leopard aswell. Finaly I was testing snow leopard stuff and the vanilla kernel was booting on my 780i so has nforce surort also increased?

    Most likely because it will get broken by the next build or a subsequent build or when the final version comes out. So instead of having a bunch of different ones out there that support some versions of snow leopard it makes more sense to wait until the real release is out and then release one that works 100% with that release.

    Oh, another thing you could add to what is known about it would be native read/write support for NTFS formatted partitions.

    10a222 isn’t worth worrying about right now, its very buggy.

    So buying a ATI 3870 is not so good for future use in Snow?
    Which card would fit best for Leo and Snow now? (Mid-Price eventually with Silent cooling?)

    With the new ATI framebuffer, is it possible we’ll be able to get QE/CI on older cards? I have an ATI Radeon 9550 (128MB/AGP) that I wouldn’t mind throwing in a system I’m building…

  25. February 6th, 2009 | 5:55 pm

    So if there’s a “support” for GT200 series, it shouldn’t be very hard to port drivers to actual Leo, should it ?

    Because now i’m forced to don’t use my card or sell it and buy a 9800gx2, wich is a bit more expensive…

  26. February 7th, 2009 | 8:27 pm

    At last good news!

    It seems there is progress in ATI HD 4800 series support while the drivers are in Snow leopard dev 10A261 !

    There is shurely some work to do to get these kext working with 10.5.6 !

    What ‘s up? 3800 series do not work on snow leopard. Can we fix it. I want my 3870 to work on snow leopard.
    Any more ideas?

  28. February 12th, 2009 | 8:14 am

    […] member Leon has submitted a link via email from some random blog that seems to have a list of interesting things going down in Snow Leopard. ATI 4800 support, the plain Mac OS X kernel works on the iCore 7 CPUs and a bunch of other stuff […]

    facts about 10A261:
    nvidia drivers and safari are built for x86_64 now, though safari won’t use the 64bit binary automatically?!
    oh, and it has opencl support 🙂

    Ive been able to activate QE on my Sapphire ATI HD3870 512mb and everything runs just fine. I can run final cut pro, apreture, games, etc, etc

    could you point me to the link of the modified OSInstall.mpkg for MBR, would be much appreciated. looked all over for it
