Jakes Daddy Posted November 17, 2008 Share Posted November 17, 2008 Hi, I'm sure someone here can help with this ... Basically, I'm struggling with installing iDeneb 1.3 10.5.5 on an Acer Travelmate 4150 i915 chipset, GMA900 video. I'm close, but not quite there. I have sussed out which chipset files to install, and which kernel. The install works; and the system reboots. I get the Darwin boot screen thing, then the Apple logo; then the screen goes blue. After lots of googling and reading threads on this forum I have come to the conclusion that it is a video driver problem. I have tried the paperclip trick, no joy. I have hooked up an external monitor and if I switch between internal LCD and external monitor I can (kind of) see the next screen in the installation process (country selection I think) - but I cant see it well enough to actually use it and I couldn't see the mouse either. So, I think I'm close, just need to sort the video. I have found this thread -> http://forum.insanelymac.com/index.php?showtopic=110176 which talks about replacing a kext file, but from the way I read it, it assumes your system boots, which mine does not. So, I thought, well, the original kexts are on the dvd, surely I can replace them and reburn. But on my Windows machine I only see a top level directory of the DVD (no /system/library/extensions folder). I dont have a working mac to be able to mount the dvd. Unless of course I'm missing something - I cant book my Hackbook so I cant replace the files as suggested. Is there another way to do this? Any help very much appreciated; Cheers JD Link to comment https://www.insanelymac.com/forum/topic/136847-how-to-replace-kext-files-on-the-installation-dvd/ Share on other sites More sharing options...
Jakes Daddy Posted November 17, 2008 Author Share Posted November 17, 2008 Anyone?? Surely I'm not the only one to have had the blue screen? (regardless of hardware) - how do you replace files on a non-booting system ??

Gujal Posted November 17, 2008 Share Posted November 17, 2008 Your machine is booting, just that it has switched to external monitor as primary display. Connect an external monitor and complete the Install and initial setup process. Once finished use KextHelper and install the patched AppleIntelIntegratedFrameBuffer.kext and restart, your laptop display will start working and you dont need the external monitor.

Jakes Daddy Posted November 18, 2008 Author Share Posted November 18, 2008 Tried that but no joy I'm afraid If I boot the machine with an external LCD monitor attached, the Darwin bootloader and Apple logo appear correctly on the external display; the I (very quickly) get the blue screen on the external monitor then it turns off the display with a monitor message esssentially saying it cant support the resolution/refresh rate. If I then toggle the external/internal screen with Fn-F5, I can switch the display to the internal monitor and external monitor. When I do this, I get a partial display on both screens. I can see its asking me about country, but its like only half the horizontal lines are displayed, with the other half being black. IE. thay alternate between a black line and the correct line - interlaced ?? I've probably not explained that very well, but basically I cant see the full screen to be able to complete the install. Any other ideas ??

Hagar Posted November 18, 2008 Share Posted November 18, 2008 If you can get that far you should be able to boot -s (singleuser mode) which will give you a commandline from which you can move, delete, and with a bit of luck even add files.

Jakes Daddy Posted November 18, 2008 Author Share Posted November 18, 2008 Thanks for the reply Hagar - I'm close, yet so far ! I can boot -s to get a console prompt; and I have read/write access to the disk. I can cd into /System/Library/Extensions and see the files I need to replace. But ... I cant mount either the CD or a USB drive to copy the replacement kext files from When I try to mount the cd with mount /dev/disk1s1 /tmp/extdisc I get permission denied When I try to mount the usb disk with mount /dev/disk2s1 /tmp/extdisc I get Incorrect Super Block (which after some googling I think means its the wrong file system !) Any ideas ?? Link to comment https://www.insanelymac.com/forum/topic/136847-how-to-replace-kext-files-on-the-installation-dvd/#findComment-970472 Share on other sites More sharing options...
Jakes Daddy Posted November 19, 2008 Author Share Posted November 19, 2008 Woohoo !!!! Sorted it !! OK, so my blue screen problem after install is fairly easily sorted - as suspected it was a video driver problem. If you have the same problem what you could try is boot the machine in single user mode (F8 as its starts to boot to get the Darwin bootloader prompt, then -s) This boots a command shell Then (as instructed on screen) type fsck -fy mount -rw / Then cd /System/Library/Extensions and delete (some) of the video kexts (I say some - I probably deleted more than needed) The ones I deleted were: AppleOnboardDisplays.kext (I think this is the key one) AppleIntelG*.kext (this gets rid of the Intel GMA and GX drivers) AppleIntelIntegratedFrameBuffer.kext (not sure what this does/did) having deleted these, type exit at the prompt, and the system logs you out of single user mode, and continues to boot the GUI and allows you to complete the install So, I now have a nice (semi) working machine - Acer Travelmate 4150 with sound, power off, volume control via keyboard, no network (yet), no trackpad (yet) and probably non-hardware accerleted video (yet ) - but its a start and I am well pleased with it Now I'm heading off to the Post Installation discussions ....
