to add on to what everyone is replying with, "still waiting for root device" is a known error BUT the cause is an unloaded chipset extension.

to remove an extension you need to boot up into single user mode (this was never stated earlier in this post... come on guys)

but I don't think that is the issue in this case. the NForceATA kext (depending on which variant you are using) only allows a maximum memory of a little under 4GB and since you are using 4GB RAM I think your timeout issues are happening because of this.

Also, the output you are reading from verbose mode about the AppleNForceATA kext "dropping" the device from your earlier post:

Quote:

"Found and disabled AHCI in the BIOS and AppleNForceATA was working at first (found 1 device), but then it found 0 again..."

this is normal. don't freak out. it happens on mine every time I boot up but it never drops anything.

USBF: 6.751 AppleUSBOHCI[0x73a1800]::Found a transation which hasn't moved in 5 seconds on bus 0xb, timing out! (Addr: 4, P: 0)

This error is occurring because you've got some device attached via USB and it isn't responding. disconnect it unless it is your root hard drive.

First I'd like to test a few things out here. try to fix permissions

boot up into single user mode (-s) then follow erick2red's code (but I've modified it just a bit)

Code:

/sbin/mount -uw /
cd /System/Library
chmod -R 755 Extensions/ && chown -R 0:0 Extensions/ && touch Extensions/
rm -Rf Extensions.*
reboot

when you reboot use the boot flags:

Code:

-f -v maxmem=2048

(remember to include the spaces in between the different flags: "-f" "-v" "maxmem=2048")

Let us know how this works out.

Just came back from looking and troubleshooting more, and can't get over my latest error after doing erick2red's fix:

Quote:

USBF: 0.708 AppleUSBOHCI[0x4735800]::CheckSleepCapability - OHCI controller will be unloaded across sleep
Still waiting for root device
Still waiting for root device
... (etc)

I also tried "-v -f maxmem=2048" -- same error.

Edit (note): The only USB devices attached are my keyboard and mouse.

I was informed that my system makeup could use the retail DVD with the boot-132 method. I think I'll just do that, because the other chipset driver didn't work, either.

I cannot speak for the IPC distro as I have not tried it but I have had excellent results with iATKOS 5i (10.5.5) using the FASSL Kernel (Genuine Intel Hardware). Whatever distro you choose you need to make sure you get a good clean copy of the ISO, there are lots of duds floating around the web.
