I did this also and it seems to be working. I can now boot with out the -F flag and UDMA seems to be working altho this drive is so old i only score about 20mb writes with it still better than the 5mb I was getting before this. Only I didn't use the Terminal I used Xray instead, I have use windows to Long and am not comfortable with cmd lines anymore ;(

I have a MSI KN8 Neo2 Platinum(Nforce3 250gb, I think could be the ultra not sure)

Xbench Score = 62.44

That seems to have worked for me, too. Although i didn't xbench it yet. Nor did i reboot for a second time.

Edit: It booted three or four times. Then it wouldn't start any more. Don't know wether this was a problem with MacOS or some strange problem with my PC. I lost two partitions on my primary HD between MacOS-Reboots and have spent some hours now on restoring them with testdisk. I think i'm gonna take a break from OSX86 now. I nearly lost some 120 GB of data. Including some important files. Of course the last backup was >4 months ago...

Worked for me as well, random reads/writes are still painfully slow <1MB but its survived a few reboots.

Thx to everyone that worked on that! Now I got my battery information and sound at the same time! No kernel flag necessary! Thx also to Macgirl for linking her compiled kext. That worked perfectly for me!

I have shutdown and booted the computer 5 or 6 times now, (all without the -f flag too). Everything seems to be running smooth. (I haven't "rebooted' it once because it still hangs on a restart from within OS X)

If platform=ACPI restart doesn't work on all only shutdown, and if platform=X86PC shutdown doesn't work only restart, kind of weird.

Ok, I just ran across this thread, and I'm wondering if any of you have gotten this working with a 0x00e510de Device ID (K8N Neo2 Platinum) My HD read/write speeds are HORRID! They bring my overall xbench score down by literally half.

im trying to get this to work on my nforce4 how do i get into the part to type in { 0x01bc10de, 5, "NVIDIA nForce" },
{ 0x006510de, 6, "NVIDIA nForce2" },
{ 0x00d510de, 6, "NVIDIA nForce3" },
and also how do i compile ive installed xcode but don't know how to open the kext what files do u open?
or could someone post their nforce4 driver that they compiled,thx

You need the SOURCE files for AppleOnboardPCATA.kext. You can find it on the apple developer connection site (free registration).

Direct link

so i've done that tried to compile it, put my hardware ids in used all the files on this forum and it still says permission errors when i try kextload and also it still uses the generic instead of onboardpcata kext

You have to edit the Info.plist file too. Just add your pci address into the Nvidia nforce section. And dont forget to set ALL FILES IN THE DIRECTORY permissions to 755, chmod to root:wheel and delete the Extensions.mkext and Extensions.cache so the system reloads all extensions on boot.

P.S: you need some basic unix skills to do anything in macosx since its an unix operating system.

yeah well this is like the first time i've done anything like this so thanks for your help

AndyMS,

I've got the same DFI LanParty nF3 250Gb board like you and a spare 80 GB IDE Maxtor only for Mac OS (my Win XP is running on a SATA 120 GB drive).

Are you sucessfully working with this patch? If you do, please send me the file! This is the only fix I could'n manage to do it yet. I've got audio finally working, network (with a spare cheap Realtek card) and everyting else, but I still need to boost my HD.

Does anyone have this working on the Gigabyte k8ns pro? if so, could you please send it to me!

Bleh, no dice for me on speed boost, put the new AppleoboardPCATA into my existing IOATAFamily, still get the same low read/write scores, damn cursed thing

Same :/

I got it to work, I keep forgetting that you have to delete the Extension.kextcache & Extensions.mkext (which I NEVER thought to do so everytime I rebooted OSX, I had to load my audio.kext, thankfully I don't have to do that anymore lol)>.<

I should put OSx86 on my SATA raptor, the drive I use is kinda old, so I'm only getting 50 average across the boards.....but that's ALOT better than the 3.xx I use to get.

All we need now is a working Nvidia driver

How do i delete the cache?
Don't want to stuff anything up, already formatted about 10 times lol
{Edit] Found it

Great for you.

I'm still trying to fix this on my nForce 3 250GB. Is there anyone who could teatch me how to do in a easy way?

How do you tell whether your drive is running in UDMA mode or not, other than using benchmarks? I'm currently running on a very slow drive from an original iMac, so benchmarks aren't going to be a reliable way of telling.

MSI Neo2 Platinum (Nforce 3)

It still would be a effective way to tell, if you're only getting 3MB/s, you're not running in UDMA, as even those old HD have times of 15MB/s.

Hi all

I have an Asus K8N Motherboard with nForce3 250 on it.
I want to enable UDMA but I don't wanna end up with a "still waiting..." message cause i'm not really experimented with mac kext stuff and all.
Is there a safe way of doing it?
Could someone post a small howto guide?
Thanks.

Ok, i'm getting on my nervs right now.

I've downloaded all files needed but still don't know what exactly what to do with them! Is it that hard for you expert guys teach a simple guide for us?

I mean.. i'm not a computer newbie, but not an Apple Developer also. In fact i'm a programmer but i just can't understand how it works.

Is it so hard to give us a binary file already done for 0x00e510de. I saw at least 5 other persons here trying to "develop" this binaries without any success. Woundn't be easier to release this file already done and SIMPLE directions to install them?

equinox? macgirl?

Please!

Hi,

The same on my side. I have done everything mentioned but
always get dependency errors.

It would be really great if someone could post the
compiled driver for 0x00e510de + idiots guide.

Thank you

Best regards

Mole

first off thanks everyone for the hard work...after this fix/patch my computer feels 100 times better.

I used this: thanks bikx86

I opened up the package contents of the IOATAFamily.kext linked to previously in this post, and pulled out only the AppleOnboardPCATA.kext package. I put that into the IOATAFamily.kext package that is already in the /System/Library/Extensions folder. Then I ran:

sudo chown -R root:wheel IOATAFamily.kext to make sure that every file in that package was on the same page. It seems to be booting fairly reliably now.


only drawback I have to boot w/ -f (no biggie though)

Questions taken from this SHORT explaination:

I opened up the package contents of the IOATAFamily.kext linked to previously in this post, and pulled out only the AppleOnboardPCATA.kext package. I put that into the IOATAFamily.kext package that is already in the /System/Library/Extensions folder.


"I opened up the package contents of the IOATAFamily.kext"

How do you open it up ?!


"and pulled out only the AppleOnboardPCATA.kext package."

Is this file inside of IOATAFamily.kext ?


"I put that into the IOATAFamily.kext package that is already in the /System/Library/Extensions folder."

How do you put AppleOnboardPCATA.kext into IOATAFamily.kext ?

Thanks. I were already writing the same questions here

The explanation was helpful but could it be a bit more "newbie"? Or would kill you to post these files here?

Will I have to beg (more) on my knees ?

AppleOnboardPCATA.kext is not a file, is a whole directory, so you need use "cp -R" or "mv", something like this:

sudo cp -R AppleOnboardPCATA.kext /System/Library/Extensions/IOATAFamily.kext/Contents/Plugins/

then do the "sudo chown -R root:wheel IOATAFamily.kext" command.

macgirl, what is the complete path to this Info.plist? (eg: /System/Library/Extensions/IOATAFamily.kext/...)

I´ve finally did the replacement of the files but it worked only on the first boot. On the later boots it was DMA only again so I thing this might be Info.plist problem.

path after moving the kext is:
/System/Library/Extensions/IOATAFamily.kext/Contents/Plugins/AppleOnboardPCATA.kext/Contents/Info.plist

Did you erase the caches before booting?
/System/Library/Extensions.kextcache
/System/Library/Extensions.mkext

Ok, I'm not sure if i did everything well... I downloaded AppleOnboardPCATA.kext, copied it in my "home icon/root?" directory, then in terminal, did the command:"sudo cp -R AppleOnboardPCATA.kext /System/Library/Extensions/IOATAFamily.kext/Contents/Plugins/". Then downloaded IOATAFamily.kext, did this command:"sudo chown -R root:wheel IOATAFamily.kext".

Now I don't know how to do the next steps...

Must I edit an Info.plist file somewhere? If so how do i proceed?
Must I erase caches? I don't know how to do that...

If you download and move the IOATAFamily.kext after you moved the AppleOnboarPCATA.kext you overwrite it.

Just move AppleOnboardPCTATA.kext and edit it's Info.plist

And.... what about Epox 8KDA3I ?...

OK! It's finally working here!

Thanks Macgirl and everyone else for the help!

Ok... i've:
"sudo cp -R AppleOnboardPCATA.kext /System/Library/Extensions/IOATAFamily.kext/Contents/Plugins/"
"sudo chown -R root:wheel IOATAFamily.kext"
Then... nothing.
I have an Epox 8KDA3I Mobo with nForce3 and problems with DMA.
What have I edit in info.plist to get this perfect Mbits?!

P.S. forgive me my bad english...

try the kext in this thread http://forum.osx86project.org/index.php?showtopic=2704 it should be easy to install and it should work on your epox , i've a nforce 3 250 too

anyone have luck with NF4? I tried and unsucessful!!!
I got the infamous "Waiting for root device"

Thanks in advance

Yes I have.

what did you do?
Thanks

Modified the nVidia c++ code part, build in xcode, edit the Info.plist of the resulting kext, then replace it, delete caches an reboot.

Thank you very much macgirl, I got my NF4 ATA working using your attached kext file! I have same device ID as yours. I got 10 time higher HD transfer rate. Maybe you should add it to wiki for NF4 MB. I just found your post under this topic.

That's on standard IDE and after running the nForce3 250 fix posted in another thread on here... the better nForce3 250.

That's some insane speed compared to the paltry 5-6 I was getting before...

I'm definitely impressed. OS X FLIES now.

i need help, some body send modified nf4 kext file link ?? sorry my bad english :L

http://forum.osx86project.org/index.php?sh...findpost&p=5825

How about everyone specify which motherboard they have and what the device id is? Not all of us have windows installed and can get our device id that way.

0x005310de is for nforce 4
0x00e510de is for nforce3 250 rev 2
0x00d510de is for the first nforce 3

0x006510de , 0x01bc10de are for nforce 1&2 i don't remember in which order

You can use a Linux LiveCD.
