iatkos 5i not booting after update to 10.5.6
 

I think i must have misunderstood, but i read that iatkos 5i can be updated like a regular mac..so i applied the update from inside the OS, and on reboot, it hangs.

Any ways to make it work or at least rever to 10.5.5 without reinstalling from scratch?

My update attemp to 10.5.6 went wrong too. I could restore my system with the installation dvd using my timemachine backup. After reinstalling chameleon bootloader everything is working like before.

Good luck!

what if i dont have any backups on timemachine?

Tell us where it hangs. If your getting a blank screen with Apple logo use -v on boot and tell us where it stops.

Place your specs in your signature will help us too.

it hanged once after mounting the other hard disks, and once i dont remember where...

anyway meanwhile i reinstalled it and i will keep it to 10.5.5 .

also i have changed my video card since i was on VESA with my GTX 280. Now im on a 7200 GS 128 RAM , im not on vesa anymore, but one of the main reasons for installing mac, LOGIC (audio application) still detectes 0 MB VRAM.

i have chosen at installation the Titan drivers for nvidia and i might have chose the NVinject also (im not sure though). In System Profiler at Graphics there are 128 MB Vram, and at ROM says NVinject 0.2.1 ...maybe anyone can help me with this ? :)

Thanks

You don't want to select multiple graphics drivers.

Lets try this for your graphics card.

1. Go to http://nvinject.free.fr/ and download Latest_NVinject.0.2.1.zip

2. Go to the /System/Library/Extensions folder and remove existing graphic's kexts. (NVinject, NVkush, NVdarwin & Titan) You may want to back them up to a folder on your desktop or a USB thumb drive.

3. Unzip the file you downloaded and drop NVinject.kext into the /System/Library/Extensions folder.

4. Open Terminal and type the following to correct permissions to the Extensions folder. 5. Then type the following to repair permissions to your entire drive. 6. Then type the following to remove the Extensions.mkext cache file to force OSX to rebuild it with the new NVinject you installed. 7. Reboot with -v -f

Check to see if QE/CI is supported.

thanks a bunch im about to try it now, a quick question before: is there any chance my system wont boot aftewards and i will have to do a new install?

on the " sudo chmod -R 755 /System/Library/Extensions && chown -R root:wheel /System/Library/Extensions " command , i get :Operation not permitted ...is it normal ?

With graphics drivers generally not. You could remove all of them and restart and will get default 1024x768 no QE/CI. I generally tell people when the do an install to not even select any graphics options as selecting the wrong option or multiple options can cause problems. I recommend that you back these files up to your desktop or a thumb drive as good practice. You may in the future, have to replace kexts and it is a good idea to keep them handy so that if you can't get back into OSX you can replace them in Single User Mode -s to avoid having to do a complete reinstall.

hopefully i wont have to do a full reinstall...

now what do i do with the Operation not permitted ? (post above last post of yours)

Type this in terminal:
Reply back with what it says.

-r-sr-xr-x 1 root wheel 48160 Nov 29 2007 /usr/bin/su

Hmm it it were to have said -r-xr-xr-x then we should have been able to type "sudo chmod 4555 /usr/bin/su" but since it doesnt I am not too sure. Type and tell me what it says.

/usr/bin/su

Everything looks correct. Try typing (pressing enter after each line):
If it gives you the same error, make sure /System/Library/Extensions/Extensions.mkext has been deleted and go to Disk Utility and select Repair Permissions. Then reboot with -v -f

so far so good...its now fixing permissions ... im waiting , no more operation permitted when doing the commands one by one..
The final result is:
p.s. i just checked for Extensions.mkext , is there..should i delete it?

Yes delete it right before you reboot. You can use this command provided you have not exited Terminal:
If it gives you problems then try:
Remember to use -v -f when you reboot.
-v Verbose Mode
-f Forces OSX to pull drivers from the Extensions folder and not the cache file. I know we just deleted the cache file but its still a good idea.

just restarted, now im in 1024x768 (before this i was in 1680x1050)

p.s. : now i have 256 vram (actually my 7200 gs has only 128), but Logic still says my system has 0 VRAM

I did a little research on your card and found a few others having the same issue. Do you know the model & Manufacturer of your card?

Lets give NVkush a try. There is a link to it in my signature http://diabolik1605.com/DHF/

Follow the previous instructions of removing related graphics drivers and then drop NVkush.kext into your /System/Library/Extensions folder.

Reboot with v -f

NVinject & NVkush have worked out of the box for most of the projects i have done. Others have had success with EFI strings though Ive never messed with it. Ill point someone to this post if NVkush doesnt work for you.

oh oh oh...my big bad..
now i looked on the card box, its a 7100 GS MSI ... im not using this card since i got my gtx 280 so i didnt know exactly, sorry..

so, its: MSI NX7100 GS 128 RAM

The reason the above didn't work is because the "&&" doesn't carry over the sudo command. you need to type sudo twice so it should look like:
or like it was later stated...

Just for future reference...

No problem. Give NVkush a try and if it doesnt work lets try to get your Device & Vendor IDs.

I would download DPCI Manager here: http://duddie.kazzuya.com/proj/DPCIManager_01.zip This tool allows you to find the Vendor & Device IDs. Its a handy tool to have if you have some devices that are not working.

It will show you something like this:

For example the numbers on the left in the first column are the Vendor IDs and the numbers on the right in the first column are the Device ID. Find your Video Card's vendor & device IDs

With these numbers we can better check support for your card. In some cases you can add these numbers to kexts to get them up and running.

Though try NVkush first. We can also compare the IDs you get from this program with what your system thinks your card is. For example, in your last post it shows:
Vendor: NVIDIA (0x10de)
Device ID: 0x016a
Revision ID: 0x00a1

@NFOav8or
Thanks for that. I figured Id start grouping commands. Last night I asked one of the guys about it and they said you only needed to use it once per line. I was too lazy to give it a try. I thought it was strange to have gotten that error when everything else looked good.

Im not too familiar with EFI strings so I don't really know what to advise in NVkush doesn't work. Have any suggestions?

nothing makes EFI easier than pcwiz's OSx86 Tools Utility for beginners.
Here's a post I made a while ago that discussed EFI. If the card is supported I'd recommend using it.

I hope it explains the process a little more.

The id`s from the little tool are:

10de:016a

the card is identified as: GeForce 7100 GS

im about to reboot now with nvkush

same thing...

i looked a little on the Efi post of nfoav8or , downloaded the little tool, and my card is int he list : 7100 128 MB ram...maybe you could give me some instructions to what to do using that?

Thanks, and thanks for all the help so far :)

Im at a loss on this one. If you backed up the original kexts we can restore them or re-download. Which ones did you see to delete? NVinject/NVkush/Titan...

Also check Nfoav8or's link. It discusses EFI Strings

i backed them up.

i read the post about the efi strings...im thinking to give it a try..is it still safe so that i wont have to reinstall the whole system?

also, do you think there could be a better hope if i put back my gtx 280 ?

p.s. list of delete exts (initially):
NVDANV10Hal.kext
NVDANV20Hal.kext
NVDANV30Hal.kext
NVDANV40Hal.kext
NVDANV50Hal.kext
NVDAResman.kext
NVinject.kext
Titan.kext

Good news!

I went back to the initial drivers, and following lanceomni`s advice not to have 2 drivers installed, i followed the 'procedure' , removed the nvinject and only left the Titan drivers ..and it works!!

Thanks a lot guys!

If it helps anyone else, the only files i have left from my initial setup are:

NVDANV10Hal.kext
NVDANV20Hal.kext
NVDANV30Hal.kext
NVDANV40Hal.kext
NVDANV50Hal.kext
NVDAResman.kext
Titan.kext

i dunno if NVDA and Titan are still 2 different drivers, but i think im u sing Titan now (from what i can see on a -v boot)

That is good to hear ;)

a big THANKS for all the help :)
