Hi ,

to make a story short i was finally able to install Leopard 10.5.8 on my old P4 1.6Ghz .

 

All works very well .... the install was done using Gray apple disc , no modded kext used exept for IOATAFamily to be able to boot on ICH4 PATA controller .

 

The strange thing comes with USB .

My board has 3 UHCI controller and 1 EHCI controller . The controllers are correctly listed on System profiler , as you can see from below : 

 

 

 

 

USB Bus:

 

  Host Controller Location: Expansion Slot

  Host Controller Driver: AppleUSBUHCI

  PCI Device ID: 0x24c2

  PCI Revision ID: 0x0001

  PCI Vendor ID: 0x8086

  Bus Number: 0x1d

 

USB Bus:

  Host Controller Location: Expansion Slot

  Host Controller Driver: AppleUSBUHCI

  PCI Device ID: 0x24c7

  PCI Revision ID: 0x0001

  PCI Vendor ID: 0x8086

  Bus Number: 0x5d

 

USB Bus

 Host Controller Location: Expansion Slot

  Host Controller Driver: AppleUSBUHCI

  PCI Device ID: 0x24c4

  PCI Revision ID: 0x0001

  PCI Vendor ID: 0x8086

  Bus Number: 0x3d

 

USB High-Speed Bus:

  Host Controller Location: Built In USB

  Host Controller Driver: AppleUSBEHCI

  PCI Device ID: 0x24cd

  PCI Revision ID: 0x0001

  PCI Vendor ID: 0x8086

  Bus Number: 0xfd

 

 

Drivers seems to be correctly assigned to the controller , mouse and keyboard works perfectly , but whenever i connect a USB 2.0 device (like a flash drive , or an external HDD ) , the device gets assigned to the UHCI controller . 

 

Does anybody know if there's a solution to fix this issue ? 

I don't thinks is has something to do with IOUSBFamily kext since USB controllers are recognised by the system , could it be IOPCIFamily kext the source of this problem .

For SL (10.6) there's a patched version of this kext for those experimenting the same kind of problem , but i could not find a suitable kext for my version .

 

Thanks to anyone who will help me solve this problem !
