ext2fsx

Hi, just installed 10.5.2 rev.2 on my system (nForce4, Opteron 185, 8800GT, external USB disk) - works like a charm, just like the previous rev. Thanks Zeph, great work! Shutdown is a bit iffy and DVD playback doesn't work, I'm assuming…

Hi, just installed 10.5.2 rev.2 on my system (nForce4, Opteron 185, 8800GT, external USB disk) - works like a charm, just like the previous rev. Thanks Zeph, great work!
Shutdown is a bit iffy and DVD playback doesn't work, I'm assuming this is to do with my graphics card? Neither are show-stoppers though.

Anyway. I installed ext2fsx, I have an internal drive with a NTFS and an ext3 partition. NTFS is read just fine (with ntfs-3g), but on startup I'm told that "the system extension /Library/Extensions/ext2fs.kext was installed improperly and cannot be used". So of course I can't mount my partition with ExtFSManager either. Anyone here seen similar problems?

Many thanks,
Mike

Thanks for the reply! I have no problem with chown'ing... but I downloaded the AppleACPIPlatform.kext from OSx86.hu, and I'm not quite sure how to install it. Do I just copy it over my current files? I don't expect to be spoon-fed, but if you could point me to a place that has some sort of instructions, I'd be really grateful! for your time, Mike

Author Update #2 @Mikeintosh 2008-03-14

Thanks for all the help!
Changing the permissions for ext2fs.kext did indeed get it working.
Sadly replacing my AppleACPIPlatform.kext and AppleSMBIOS.kext didn't work - in fact, they stopped my PS/2 keyboard and mouse from working! Fortunately I had a USB mouse and keyboard lying around, so I copied back my previous kext's. So now I'm back to square one. The shutdown irregularities are not that big a deal, but when I start the DVD Player I get:
"There was an initialization error - A valid video device could not be found for playback. [-70017]"
Is this something to do with my 8800GT card? Do I need to edit some plists inside a kext maybe?

Thanks again whether you are able to help or not, Mike

[cite] roisoft:did you try the mach_kernel with shutdown fix?

I thought it's included in Zeph's 10.5.2 rev.2?

[cite] roisoft:do you have CI/QE for your 8800gt ?

Core Image: Software
Quartz Extreme: Not Supported

I'm assuming that's the problem. I don't think anyone has got QE working with a 8800GT, or am I wrong?

Field Note #1 @roisoft 2008-03-13

for Shutdown problem go to irc.osx86.hu and try the Appleacpi fix reboot/shutdown or another kernel with shutdown fix, for DVD go here (my.macd otnub.info/content/view/19/26/) and download the new applesmbios and for ext2fs.kext correct the permissions (chmod/chown) or install again using kexthelper.

Field Note #2 @xx66stangxx 2008-03-13

1. Copy the (new) kext files to /System/Library/Extensions

2. Open the Terminal & type the following Commands (hit enter after each line):

sudo -s (-> your root password)
sudo chown -R root:wheel /System/Library/Extensions/[NAME].kext
sudo chmod -R 755 /System/Library/Extensions/[NAME].kext

rm -r /System/Library/Extensions/Caches

reboot

Now use -f at boot to force the rebuilding of kext files.

Field Note #3 @roisoft 2008-03-14

did you try the mach_kernel with shutdown fix? do you have CI/QE for your 8800gt ? if so, try with marvin utility, maybe you need some kind of cpuid ...

Field Note #4 @roisoft 2008-03-14

you´re wrong, you need edit the info.plist for nvdaresman, geforce ,NVDAN50hal.kext and put only your device ID,

Field Note #5 @WinLinMac01 2008-04-13

How do you change the permissions to get the kext working? I am getting the same error. Also, where is the kext located on the DVD? In the extensions folder? Please let me know. Thank you very much.

Field Note #6 @WinLinMac01 2008-04-13

looks like I won't be needing ext2fsx. I don't have to access linux partition from mac. only ntfs is all I need for all of my other data, lol. Time to party, =)

Field Note #7 @seren 2008-04-14

winlinkmac01,

sudo chown -R root:wheel /System/Library/Extensions/
sudo chmod -R 755 /System/Library/Extensions/

On my machine at home there is an app that will do it for you with a double click and by entering your password... ill up later

Field Note #8 @Puttabong 2008-04-14

Field Note #9 @seren 2008-04-14

Field Note #10 @romefolks 2008-04-15

where can i get the ext2fs.kext from? i selected it on install from the zp 10.5.2 r2 but it said it was installed wrong. when i tried to repair it..it said it does not exist on my computer? I just need a new one. I actually need it.

Field Note #11 @romefolks 2008-04-15

if i cant get the ext2fs fixed..at least how do i stop that annoying "the system extension /Library/Extensions/ext2fs.kext was installed improperly and cannot be used" every time i boot up?

Field Note #12 @WinLinMac01 2008-04-15

@rome, I can't even locate that kext. I would delete that then restart. That would fix the problem eventually, however, that is not the case. Darn, =(
