Hello everybody , I need your help .. I installed Mac OS X Snow Leopard with the tonyx86 tutorial ( retail installation , [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] + [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] ) I updated to 10.6.5 , and it works fine after i installed some kexts .

 

But I have a problem with the USB transfers , it's SLOW as hell .

 

Here's a screenshot of the usb panel configuration ( don't know how it is called ) :

Do you have a solution ? Is there a kext to install ?

 

THANKS in advance .

 

Configuration :

Mobo : ASUS P5LD2-x/1333

CPU : Intel Core2Duo 2,2Ghz

2 gb crucial 667MHZ DDR2

Gigabyte 8600GT 256mbDDR3

 

MAC OS X 10.6.5

 

By the way , I also have a 13" macbook pro 2010 and when i plug the usb drive , it says " jusqu'à 480 MB/s " at the line " speed "

OS X cannot talk to your USB 2.0 controller (USBEHCI) for some reason, your USB ports are working at USB 1.0 speeds.

 

This is what it's supposed to look like:

That's strange, ICH7 is fully supported in the Apple USB drivers. But system Profiler does not even see your EHCI controller.

 

Tell me what USB settings you have in your BIOS.

 

If you are using the Chameleon bootloader, try adding USBBusFix=y to your /extra/com.apple.Boot.plist.

 

USB SETTINGS :

USB FUNCTION : enabled

Legacy USB Support : Auto

USB 2.0 Controller : enabled

USB 2.0 Controller Mode : HiSpeed

BIOS EHCI Hand-Off : Disabled

 

It's an American megatrend inc BIOS , and yes it's Chameleon.

rename the AppleHPET.kext (AppleHPET.kext.bak) in your /S/L/E/ dir and reboot . . . :angel:

 

What do you mean by /S/L/E/ ? And where can i find AppleHPET.kext ? Spotlight can't find it ..

I don't get every technical terms , i'm a real beginner so please be kind with me : )

 

( And forgive my english , i'm french ! )
