[edit] nForce SATA

[edit] No detection of SATA at boot in nForce3 once MacOS 10.4.6 is installed

After installing OS X 10.4.6 native with VMware with any of the method listed in the installation guides, the first boot was OK, configure the OSX with keyboard, personal info, etc...But when you turn it off and on again, it freezes in the holy "Still waiting for root device". My solution was, start OSX with the -v -x flags, for my surprise it recognize the SATA disk and start in safe mode. Then i went to Terminal, entered as root and typed the following...(extracted from "AppleVIAATA.kext" Method)


 rm /System/Library/Extensions.kextcache

kextcache -k /System/Library/Extensions/

kextcache -L -N -e

Then rebooted and everything worked fine...

Seems like reloading the extensions cause OSX load the SATA driver correctly at boot. If someone know why, you are welcome :) . reply for why does this happen----- when i was installing osx with windows installed,i by mistakely deleted the windows partition which became in red coloured text..... i thin something important file was deleted .....

[edit] You can use chroot to run this from the installer disc

Note that you can operate on an already-installed copy of Mac OS X from the install disc by accessing the Terminal utility. kextcache will crash, however, as it doesnt have write access to /tmp (as its mounted to a location on the read-only optical disc). You can work around this by running another instance of bash inside of chroot... type chroot /Volumes/MyOSXInstall bash and the new bash shell will have a root path set to the root path of your installed volume. kextcache will work correctly. . .

[edit] Other Problems

Likely problems:
SATA
Hard drive not set as Primary Master
Incompatible hardware
CMOS Checksum Bad Error

Solutions:
"AppleVIAATA.kext" Method
Make Hard drive Primary Master hd 1
If you are using a SATA disk, make sure it is set for IDE legacy mode in the PC BIOS and not 'enhanced'
Get a IDE Hard Disk(you can attach the IDE hard disk, but still install the OS on the SATA drive. It just helps to get past the "still waiting for root device error".)
If accompanied by a CMOS checksum bad error at boot, reload BIOS optimised defaults, change to AHCI and HPET to 64-bit mode. (Post them if it is not listed)
Unplug all drives from the motherboard (CD/DVD) except the install drive and install via a USB DVD drive. It seems that OSX86 tries to install to a DVD drive on occasion. This worked for me on 7 different machines with this issue. You may reconnect after the install.

BootLoader
Sometimes the version of the BootLoader is too old or too buggy that it can't detect the Hard-disk so Try to update the boot loader version manually voodooprojects.org
or using any Automatic Tool Like "Chameleon Wizard" or "Champlist"
