PaulusUK Posted January 3, 2007 Share Posted January 3, 2007 (edited) Dear Fellow OSX86 users! I feel I have thoroughly scowered the forums for random help alot but have not found a complete guide for SATA support under the SB450 chipset (afaik it's only on the rdx200 motherboards) , so it's time to (try!) and give some kind of untested guide: Ok.. download the attachment and place it into your /System/Library/Extensions folder.. just drag it in (overwriting the old file), and then type your password when prompted. Delete AppleVIAATA.kext from this extensions folder. Now open the console and sudo -s (now you type your password) cd /System/Library/Extensions/ chmod -R 755 IOATAFamily.kext chown -R root:wheel IOATAFamily.kext I think thats it! but to be safe.. cd .. rm Extensions.kextcache kextcache -k /Extensions Now reboot 2 Success stories so far, so I look forward to some results(good and bad). I can't guarantee this will 100% work, but it's worth a go! Allot of credit is due to Zappadoc and particully diegooo from these two threads (which I used to make this) http://forum.insanelymac.com/index.php?sho...97&hl=SB450 http://forum.insanelymac.com/index.php?sho...51&hl=sb450 P.s I Don't know how clever this method is, as it involves deleting some kext- which doesn't seem too smart- but it works, so meh.

PascalW Posted January 4, 2007 Share Posted January 4, 2007 (edited) Unbelieveable it works! Thank you so much! I'm going to reinstall Os X again now on my sata disk Should be much faster! Thnx! what I do notice is now that I've added it to my current installtion on my IDE disk it boots much slower (double time) but the performance in system is still the same. I also see some dependancy errors: com.apple.iokit.IOATAFamily: there has been found no valid version of dependancy apperently it causes slow boot times, how can we fix this?

PascalW Posted January 5, 2007 Share Posted January 5, 2007 (edited) I keep getting diskarb errors though. Slows down my boot time with 20-30sec! Do you guys have this too? BTW whould a raid striping set up work with this? Edited January 5, 2007 by PascalW Link to comment Share on other sites More sharing options...
PaulusUK Posted January 6, 2007 Author Share Posted January 6, 2007 I also get the Diskarb errors. It's definatly to do with what we've done unfortunatly No idea about raid PascalW, but from what i've read it's unlikely to work :/ No harm in trying. I got a massive speed increase using this method, but thats because I was switching from the crappy ATI IDE driver thats got some problems.. If your switching from IDE to SATA you may not get much of an increase as Hard drives only read around 100MBs max, so they arn't fully utilized under ATA133 even.

I was switching from the ATI ATA driver to, but that wasn't so bad at all. I do notice quite much improvement though. Only to bad from the diskarb errors and that causing very slow boot up. My ata disk even booted much faster But well we can't have all right, faster system is more important to me then fast bootup. But maybe we can find a way to kill the diskarb errors.

mystlynx Posted January 7, 2007 Share Posted January 7, 2007 It still use AppleVIAATA.kext in /System/Library/Extensions/IOATAFamily.kext/Contents/PlugIns/ It's not a new solution Link to comment Share on other sites More sharing options...
deadlyquirk Posted January 24, 2007 Share Posted January 24, 2007 This worked on my toshiba laptop. running osx86 natively is just freaking amazing. One problem, when diskutil fixes the permissions on the drive, it stops booting. And on my machine after deleting the other file, I wasn't able to boot my partiiton in vmware to fix it. I'm looking into a fix for it though. Link to comment Share on other sites More sharing options...
bigdaddystep Posted February 2, 2007 Share Posted February 2, 2007 I have tested this with the SB600 does not work for that SATA. Just wanted to let the the bloke know that asked. Link to comment Share on other sites More sharing options...
perro Posted September 16, 2007 Share Posted September 16, 2007 It works for SB600 if you add the following PCI id to AppleVIAATA.kext: 0x43801002.You should put that ID next to 0x43791002 which is the id corresponding to SB450. Link to comment Share on other sites More sharing options...
XStylus Posted September 18, 2007 Share Posted September 18, 2007 It works for SB600 if you add the following PCI id to AppleVIAATA.kext: 0x43801002.You should put that ID next to 0x43791002 which is the id corresponding to SB450. If that works, this will be epic. Has anyone tried this yet? Link to comment Share on other sites More sharing options...
