GUID cloning
Anyone clone a GUID drive before? Have any issues? Was going to clone a working 10.5.2 GUID install. Figure I will just have to flag it the same as the original for EFI.

Ahh I just posted to disregard my questions, cloning it worked just as I thought. But i was pleasantly surprised by the improvement in disk speed on GUID vs. MBR. Also Has anyone played around with IOATAFamily.kext? I notice if I move the AppleNforceATA inside of it, and remove the other that overall performace increases, as does the decrease in spam while booting.
Ok ill attach it here if it lets me. Remove you old AppleNforceATA and just install this. I used to get lots of yellow text spamming during bootup, but with just this it only detects my nforce chipset once. As far as GUID vs. MBR my disk score went up about 10.5 points which seems like a fair amount.
This on a SATA disk, overall disk score went up from 87 to 97.5. Be sure your Device ID is in the AppleNforceATA inside the IOATAFamily before you replace it, or you will get the "waiting for root device".
hmm let me look into it. I dont even have an AppleUSBEHCI file.
What motherboard are you using? I have neither of those files.
Ok i am not sure what one has to do with the other. AppleUSBEHCI/OHCI are inside IOUSBFamily. I am not sure where they might cross reference.
If your loaded back up, could ya look on the profiler and tell me what device ID and vendor ID show up under USB?

Ya, I'd be interested to know that too. Is there something that can be run from a CD, DVD, thumb drive, etc. that can create and/or restore a disk image (oops! here it comes: easily, simply, quickly…)
eddie11c, on a 10.5.2 EFI + GUID System? If yes, I'd like to test your IOATAFamily.kext - want to attach it?
Eddie Ide or Sata disk? I´ve noticed guid have better performance on ide disk than sata.
Eddie11c, thanks a lot, I'm going to test right now.
I have the same small issues like you described (yellow text)
eddie, now after I replaced the file and fixed the permissions - the system does not detect any Usb devices anymore. AppleUSBOHCI can't take control.
How to fix it? Currently booting in safe mode and posting with an iPod Touch.
And also PCGenUSBEHCI or something close to that!
Do you have a backup of an unmodified ioatafamily kext?
nForce 4 Chipset + 10.5.1 zephyroth Revision 2 + your 10.5.2 update
Thanks, going to reboot and test.
That one works perfect, no yellow boot spam anymore either. Good!
