DellOsX Posted August 28, 2005 Share Posted August 28, 2005 ok, this was pissing me off immensely so I dug into it and have a fix (for Intel chipsets anyway). What it comes down to is, as you suspected, you're not running Ultra-DMA but rather PIO because you don't have a proper driver for your ATA chipset. Assuming you have an Intel system, you need to get the AppleIntelPIIXATA driver installed. If you have XCode installed, you can build it yourself; it's included with the Darwin sources. Go to http://www.opensource.apple.com/darwinsour...IXATA-17.tar.gz. Extract the archive and open the "AppleIntelPIIXATA.pbproj" file in XCode and hit Command-B to build it. Now you need to fix the permissions: in a command window cd into Build/Development and type "chown -R root AppleIntelPIIXATA.kext". Copy AppleIntelPIIXATA.kext into your System/Library/Extensions folder, reboot, and enjoy a good 20x HD performance boost (that's what I got anyway). Cut my boot time in half too.. Or if you prefer, here's a precompiled tarball. Extract the tar.gz file and copy the kext into /System/Library/Extensions. <{POST_SNAPBACK}> Can some one repost this file please?

cyrana Posted September 1, 2005 Share Posted September 1, 2005 The reason this is possible with some chipsets is they are fairly backwards compatible with ones that already have code written for them. For chipsets that aren't related to anything else (like ATI), we're probably out of luck. Link to comment Share on other sites More sharing options...
bender12 Posted September 1, 2005 Share Posted September 1, 2005 The reason this is possible with some chipsets is they are fairly backwards compatible with ones that already have code written for them. For chipsets that aren't related to anything else (like ATI), we're probably out of luck. <{POST_SNAPBACK}> The system will try to find an exact driver match based on the device ID... if it can't find it, it will attempt to use a generic driver... There is a Generic ATA driver, which is quite a bit slower, but is usually compatible. When you boot in verbose you will see something like AppleIntelPIIXATA or AppleGenericPCATA when it finds your hard drive controllers. And of course, one you're booted you can use tools such as ioreg and kextstat to see what hardware was found and what kernel extensions were loaded.

amethat Posted September 8, 2005 Share Posted September 8, 2005 [search words: speed slow hard disk drive access read write sequential random ultra dma udma] NOTE: This fix only seems to work for Intel chipsets. To check your hard drive speed, download Xbench from here: http://www.xbench.com/Xbench_1.2.dmg And do the disk test. If you're getting speeds around 2-3 Megs/Sec, then the following steps should hopefully fix the problem for you. 1) Download AppleIntelPIIXATA.kext from here: (Thank you, madcowsb!) AppleIntelPIIXATA.kext.zip (Double-click it to extract it.) 2) In a terminal: cd /System/Library/Extensions/ sudo mv AppleIntelPIIXATA.kext AppleIntelPIIXATA.kext.disabled (Just in case you already have this kext installed. If not, you may receive an error. Don't worry about it.) sudo cp [path to downloaded file]/AppleIntelPIIXATA.kext ./ sudo chown -R root:wheel AppleIntelPIIXATA.kext 3) Reboot and enjoy a speed boost. 4) If, after a SECOND reboot, the speed boost has disappeared, download IOATAFamily.kext from here: (This comes off of the Darwin 8.01 install CD.) IOATAFamily.kext.zip (Double-click it to extract it.) 5) In a terminal: cd /System/Library/Extensions/ sudo mv IOATAFamily.kext IOATAFamily.kext.disabled sudo cp [path to downloaded file]/IOATAFamily.kext ./ sudo chown -R root:wheel IOATAFamily.kext 6) Just to be on the safe side, delete the following files (not sure if this is necessary): /System/Library/Extensions.kextcache /System/Library/Extensions.mkext (Don't worry, Tiger will rebuild these files on startup.) 7) Reboot. (Remember that your original kext files have been renamed with a ".disabled" extension. If you have any problems, delete the kexts that you added, and rename the originals back to their original filenames.) I think that covers everything. <{POST_SNAPBACK}> With regards to the hard drive, are you referring to the sequential disk test or the ramdom disk test?

uidetiger Posted September 21, 2005 Share Posted September 21, 2005 Hello to everybody, I'm following all the discussions and suggestions with great interest. After installing a deficient Tiger within VMWare on a Sony Vaio Laptop I bought myself some hardware and got everything nearly perfectly running. This includes a lot of software packages, etc. I even updated a lot of programs like ITunes with the newest releases without problems. Safari and ITunes via Rosetta start up within a second and the only problems I run into a related with music software lik Garageband and Logic Pro. For this reason I downloaded the XCode Project and I ran the XBench test. Actually I'm not really sure if I need to replace my kext as the hardware seems to respond find. XBench shows several indicators for the harddisk. I will give a try. Thanks a lot to all of you for the great work. uide Link to comment Share on other sites More sharing options...

EtherealRemnant Posted October 5, 2005 Share Posted October 5, 2005 I'm pretty sure that renaming the kext will just make the system not boot... Kexts are like plug and play drivers... they won't load if you don't have the hardware. Sorry but I'd say that you're out of luck if your ATA chipset isn't supported.
