Finnaly found solution for sis ide chipset to enable udma mode!!!!!

 

TESTED WITH SIS 661 CHIPSET!!!!

 

Here is guide!!!

 

Need appleviaata.kext

 

First you need too look for device and vendor id of yours sis ide controller

 

1) open terminal

2) sudo -s

3) cd /System/Library/Extensions/appleviaata.kext/contents

4) nano info.plist

5) Now need to add your id in the "VIA SATA Controller" not in the "VIA PATA Controller"

6) save and exit

7) chown -R root:wheel /System/Library/Extensions/appleviaata.kext

8) chmod -R 755 /System/Library/Extensions/appleviaata.kext

9) cd /System/Library/Extensions/ioatafamily.kext/contents/plugins

10) and delete applegenericata.kext

11) rm /System/Library/Extensions.kextcache

12) rm -r /System/Library/Extensions.mkext

13) kextcache -k /System/Library/Extensions

14) reboot

 

Now boot with -v option you see appleviasata 8237......... loading

AppleVIAATADriver: VIA 8237 SATA (CMD 0x1f0, CTR 0x3f4, IRQ 14, BM 0xf000)

AppleVIAATADriver: VIA 8237 SATA (CMD 0x170, CTR 0x374, IRQ 15, BM 0xf008)

 

 

 

Mac os x think controller is via sata and working full udma 6 mode.

just followed the steps, it seems there no difference from before but will check if there's something wrong. Boot to full desktop took about a minute both on with solution and no solution

-v makes nothing to select one or other, I observe in some installations tha AppleGeneric loads first so even the AppleVIA is loaded second it wont function, but also I observed when a real kext is present AppleGeneric is not loaded.

 

So the better options is to move or delete the AppleGeneric kext.

Can anybody else confirm (apart from djdan2006) that this solution is working?

I'll try it at home later, but I wouldn't like to put too many expectations with reasonable prove that it will work :-)

altievane, this is exaclty the same chipset I have: SiS 648 (rev. 3)

 

Are you using this id: 0x10395513 ?

 

Apart from the steps given by djdan2006, I deleted the caches in /System/Library/Extensions.kextcache and

/System/Library/Extensions.mkext and rebooted.

 

It didn't work. Actuall, it doesn't even boot now. I guess we are having the same kind of prob.

I guess I need to restore applegeneric using windows or a live linux CD.

djdan2006, this is exactly what I've done.

Yup. That may be... Does your chipset accept SATA devices? Perhaps the problem is that sis 648 doesn't even accept SATA.

yes, i've use that id, but I can boot os x and xbench'ed it and got a score of 20.81, on the Disk test all got very low score.

 

Yes sis661 accept sata devices

 

Try to put device id in the PATA CONTROLLER!!!!

 

I cannot boot now..

altievane, do not use macdisk to restore your old files. Macdisk has broken the Darwin bootloader. It's not there anymore :-(

 

After reading the forums I've seen I am not the first one that has this problem using Macdisk. Use macdrive or a Linux Live distribution, instead.

For people seeing the problem of AppleGenericPCATA still loading, my experiences of actually having a via controller on my laptop is that the version in /System/Library/Extensions does not have the right permissions.

 

It would load VIAATA on the first restart (where it rebuilt the caches), but thereafter it would load GenericPCATA, i fixed it though by fixing the permissions.

 

Disk utility won't fix it for you, so try doing

 

sudo chown -R root:wheel AppleVIAATA.kext

sudo cmod -R 755 AppleVIAATA.kext/

 

That fixed it loading GenericPCATA

Had exactly the same encounter.

However, I have solved the problem & I have UDMA now!

The controller id should be 0x55131039. And I did not have to delete APPLEGENERICPCATA.kext.

Hope this helps!

Thank you, djdan2006. Now copying files are much much faster! :)
