As the title says, i have Toshiba Satellite C650-15h notebook, and I want to install mac os. Now, i think i did everything right, but the booting freezes with @USBF: USBEHCI Unable to initialize UIM" thing

Now, i have some questions, as I am new to this thing
1. What should i put in bios for sata mode? ACHI or Compatibility?
2. Do I need to turn off the usb legacy support because of this error message? (I read that somewhere)
3. Can anyone please help me?

Thanks in advance

i'm sorry that i reply on my message, but here is what i got while booting Kalyway leopard 10.5.2 on my notebook:

I'll start at the MAC Framework thing :

Then it hangs there, and nothing happens... What can I do? Please, somebody, help me I'm desperate...

Here is configuration of my notebook, on this link:

Satellite C650-15H - Product Specifications - Toshiba

Is this during booting to installation or first reboot after successfully installed?
What is your chipsets/cpu/video?

yes, it happens during booting... I'm not able to complete installation because of that... It just hangs there.

My notebook is Toshiba Satellite c650-15h
Configuration is on the bottom of my previous post, but here is what i think you want to know:

chipset is Intel based, i think... Because nowhere on the site of my notebook i can find it.

cpu:
type : Intel® Pentium® Processor T4500
clock speed : 2.30 GHz
Front Side Bus : 800 MHz
2nd level cache : 1 MB

and video is Mobile Intel® Graphics Media Accelerator 4500M...

Can you help me now? I am new to this Mac world

1. BIOS setup: SATA to AHCI
2. USB to EHCI
3. USB legacy disable, USB keyboard/mouse disable.

Kalyway is fairly dated. You could give it a try, if not then for Leopard use iDeneb 1.6 10.5.8, or for Snow Leopard use SnowOSX Universal v3.5 or 3.6.
Your video card won't have full QE/CI supported.

I can't set up EHCI in BIOS, I don't have that option on my notebook... Btw, iAtkos doesn't work, I tried it too, UIM cannot be initialized. I have one question... Can the card reader included in my notebook be recognized as USB device that can't be enumerated? Is that even possible?

SnowOSX Universal doesn't work either... It appears that some USB device cannot be enumerated (the same problem), and I'm desperate... I tried almost every version of OSX but it just won't boot into installation... What can I do next?

Thanks in advance

Try this:
Don't plug in any USB device.
Boot with -x -v cpus=1 (and/or busratio=20)

That is the main problem. I don't have any USB device plugged in when I try to install OSX... But i have card reader included in my notebook, and my guess is that it sees it like USB device and I think that is the problem... Am i wrong?

Card reader should not be problematic.
Check to see if you have the latest BIOS for it.

BIOS version checked and confirmed. The latest it is.
