djdan2006 Posted May 1, 2006 Share Posted May 1, 2006 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.

altievane Posted May 2, 2006 Share Posted May 2, 2006 just followed the steps, it seems there no difference from before but will check if there's something wrong.

djdan2006 Posted May 2, 2006 Author Share Posted May 2, 2006 you must to delete applegenericata.kext When you booting with -v option its loading applegenericata or appleviasata?

macgirl Posted May 2, 2006 Share Posted May 2, 2006 -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.

lanbo Posted May 5, 2006 Share Posted May 5, 2006 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 :-) Link to comment https://www.insanelymac.com/forum/topic/16457-new-solution-to-enable-udma-on-sis-chipset-working-100/#findComment-107934 Share on other sites More sharing options...

lanbo Posted May 6, 2006 Share Posted May 6, 2006 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.

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

lanbo Posted May 7, 2006 Share Posted May 7, 2006 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.

Tiburon Posted May 16, 2006 Share Posted May 16, 2006 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 Link to comment https://www.insanelymac.com/forum/topic/16457-new-solution-to-enable-udma-on-sis-chipset-working-100/#findComment-113493 Share on other sites More sharing options...
eclau Posted June 18, 2006 Share Posted June 18, 2006 altievane, this is exaclty the same chipset I have: SiS 648 (rev. 3) Are you using this id: 0x10395513 ?

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. 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!
