iPC 10.5.6 installation problem

[nijevaznokosam]

Hi

 

I'm trying to install iPC OSx86 10.5.6 Universal PPF6 Final v1.1, but I have some problems. On boot up, I used -v to see the messages, and after 15-20 seconds, install freezes. The last line of text is something like this:

 USBF Apple USBOHCI [0x4e55000] Initialize Operational Registers Non-NULL 0xbff71790

Before this line there were 2 or 3 lines of text which begins also with USBF Apple USBOHCI.

 

Does anyone know what could be the problem?

OHCI is a type of USB 1.x controller. It's conceivable that your distribution's USB drivers are flaking out over the USB controller in your computer. You might go into your BIOS and see what USB options are present; perhaps you'll be able to get the hardware into a state that OSx86 will like. If you're not relying on USB devices for basic functions (no USB keyboard, mouse, or critical external USB hard disk), you could try disabling USB in the BIOS, at least until you find a better solution (like replacing your USB drivers).

Thanks for the answer.

Well, I'm trying to install this on a notebook. There aren't any options in BIOS about USB (actually, I can't change anything in the BIOS). And the USB is type 2.0, as far as I know. I'm using USB mouse, I tryed unplugging it, but it didn't help. Is there any parameter to pass before boot? I tried -x, -f. Also tried entering ? to see possible parameters, but nothing showed.

You should be able to change BIOS options. If you can't, then either your manufacturer has really "dumbed down" the BIOS to unacceptable levels (I've never heard of this) or you're doing something wrong. Of course, if the BIOS has no USB options, then this is academic.

 

Concerning the USB version number, it doesn't matter that the computer supports USB 2.0; AFAIK, all USB 2.0-capable systems also support the earlier 1.x standard, and for that, they typically include separate USB 1.x controllers (OHCI or UHCI, most commonly). These connect up to the same physical ports as the USB 2.0 controller (often EHCI, although there are others). The "OHCI" string in the kernel message you report suggests (but doesn't prove) that your problem is OHCI-related -- either your OHCI hardware is confusing the OS X OHCI driver or that driver is being confused by something else about your system.

 

It's also conceivable that the kernel message you reported doesn't indicate a problem, and that something after that point is failing, before it gets a chance to write a message to the screen.
