New AppleVIAATA & AppleNForceATA for Snow Leopard

Hey c0rk007hck I was taking a look at the logs and saw this:

08/10/09 21:20:51    kernel    SuperNForceATA: selected PIO mode 4
08/10/09 21:20:51    kernel    SuperNForceATA: selected Ultra mode 6
08/10/09 21:20:51    kernel    SuperNForceATA: 80-conductor cable not detected
08/10/09 21:20:51    kernel    SuperNForceATA: selected Ultra mode 2

Does it means that my ata disk is in udma 2? And it is an 80 conductor cable.

What nforce controller do you have? Some of the newer ones got troubles with cable detection not working. In Linux you can disable that with a kernel argument, but I think that cant be done in OS X.
Maybe c0rk007hck can implement a toggle in the driver to ignore a failed cable detection...

I have an Asus A8N-SLI with an nforce4 sli controller. Hope this is just an error.

You can check the PIO/UDMA modes in the IORegistry, most drivers report it there. In my case with an MCP73 controller it was running in UDMA2 indeed, not a big deal with a DVD recorder (like in my case) but if you have a modern HD you will surely experience some performance hit.
I think its not an error, the driver is probably based on the linux one, and even recent linux drivers suffer from the same bug...

This is Leopard kext by MeDevil, patched by Andy for more RAM support.

What's exactly changed here?

do i just drop these kexts into my system/library/extensions folder?
do i need to remove some kexts?
will i benefit from this on my rig ?

@ vladrxpx →: you don't need these kexts because you motherboard don't have an nforce or via chipset.

great work, this new kext fix my random kernel panic problem in snow leopard.

When attempting to use this on an nForce 780i motherboard, I get constant "FEDE genero 32IOVMSegments" messages scrolling down the screen and the system startup never proceeds.

@focherWhen attempting to use this on an nForce 780i motherboard, I get constant "FEDE genero 32IOVMSegments" messages scrolling down the screen and the system startup never proceeds.

The same happens here

I'm using an nForce 680i motherboard myself

I waited, and it eventually loads. The problem is it's not a 64 bit kext!

As you can see from the following:

bash-3.2# lipo -info ./SuperNForceATA
Non-fat file: ./SuperNForceATA is architecture: i386

Seemingly false advertisement.

keep getting this error, please help

Using an ASUS P5N32-E (SLI) with nForce 650i chipset. Tried 'Applenforceata' and also 'SuperNForceATA' but the boot never completes. Last thing is always '0 units found'. Anyone have similar problems?

Would anyone like to *actually* compile this for 64bit mode on Snow Leopard? SuperNForceATA is 32bit.

Also, why have the links toi the original threads over on InsanelyMac disappeared mysteriously?

I tried SuperNForceATA with my 680i and it works in 32bit mode but I would get a lot of log messages written to the console, and slow access on one of my drives which would eventually lead to a hang with the pinwheel cursor. I went back to the version by Andyvand (AnV) which can be found here: http://www.insanelymac.com/forum/index.php?showtopic=15… ↗ and so far so good.

However, it'd be really cool to have a 64bit version of the nForceATA driver, as this is pretty much the ONLY kext I need for my whole setup! Unfortunately I'm very inexperienced in coding, especially for the Mac so I'd have no idea where to start.

Can we bring these drivers up to date please?
