 So my problem is that my Leopard is not a Leopard its more like  a slug! :( I think i don´t have supported driver for my ATA devices. i try to find out it here: http://forum.insanelymac.com/lofiversion/index.php/t517.html I have try copy IOATAFamily.kext and from DVD but it did not help? where i find solution of this.. [edit] Xbench told me that my hdd speed is about 1.44 MB/sec :( thank you! | 
| 
 Disk speed is rather low on ATA100, I have the same problem (on nforce 4). Xbench has a lot of disk tests. I think you're talking from random uncached write or so. What do you have for a chipset? | 
| 
 yes that result is uncached write! I have Asrock motherboard chipset? - Northbridge: AMD 480X CrossFire™ Chipset - Southbridge: ATI™ SB600  here is my MoBo: http://www.asrock.com/mb/overview.asp?Model=ALiveXFire-eSATA2 | 
| 
 i dont really know what the chipset means but i think i have AM2 chipset? AMD Athlon 64 4200+ X2 | 
| 
 You had it right:  The chipset is the northbridge and southbridge.  You've got a 480X / SB600 chipset motherboard.  On my 690G / SB600 AM2 motherboard, I had to use the "SB600_SATA_ATA.kext" (maybe it was an installer...) to get the internal drives recognized and working properly.  I found it somewhere on InsanelyMac...  Maybe it's on the Wiki. | 
| 
 thanks! i find this out and try it! :D I hope it works! | 
| 
 it wont work.. :( I Installed SB600_SATA_ATA.zip! it contains 2 files: IOATAFamily.kext AppleOnboardPCATA.kext I put both files in extensions and fix acces. then i try reboot. it uses normally AppleGenericPCATADriver.kext but now it used AppleOnboardPCATA.kext! It gives me never ending IO error! about my disk0s1! :( I booted up on DVD and repaired my hdd. but i didnt try repair acces? then try boot again but it wasnt help. same IO error! then i removed AppleOnboardPCATA.kext and buuted up normally using very slow AppleGenericPCATADriver.kext [edit] I have installed the AppleVIAATA.kext in Wiki too! any ideas? | 
| 
 I'm not good at installing .kexts manually so I used "Kext Helper" to install "SB600_SATA_ATA"...  Don't know if that would do you any good or not.  Sorry it didn't work for you. | 
| 
 ok i try that. the SB600_SATA_ATA should work for me couse its made on my Asrock ALiveXfire eSATA2!! :D i read it just on insanelymac! | 
| 
 iv used that kext helper to install that on a fresh install works like a charm |
