Marcp1967 Posted August 20, 2005 Share Posted August 20, 2005 I have a toshiba equium mx laptop which uses the Intel GMA 900 chipset. I chaged the 2582 references to 2592 in the AppleIntel kext files in order to try and display 1280x800 On restart the machine displays the desktop wallpaper at 1280x800 and then freezes. If I boot the laptop with an external monitor I can change display settings (resoultion and refresh) within the MacOS and system profiler recognises the INtel GMA 900. Does anyone have any idea why the machine is hanging? Many thanks.

Marcp1967 Posted August 20, 2005 Author Share Posted August 20, 2005 EDIT: It works fine if I use the boot argument platform=acpi|x86pc Does anyone know how I can configure the system to enter this parameter automatically? Many thanks! Link to comment https://www.insanelymac.com/forum/topic/715-toshiba-notebook-intel-900-gma-display-issues/#findComment-4283 Share on other sites More sharing options...
Pixie Posted August 20, 2005 Share Posted August 20, 2005 open /Library/Preferences/SystemConfiguration/com.apple.boot.plist add follow lines to it: <key>platform</key> <string>acpi|x86pc</string> BTW: Which AppleIntel kext files did you changed the 2582 to 2592? And which argument did you used? acpi or x86pc? I have Intel GMA 900 too, but my osx still cant recognise it.

Andy4life Posted August 21, 2005 Share Posted August 21, 2005 I tried it, and after i rebooted... and fixed my permissions and everything i got a blue screen with no mouse or anything... and it was completely non-responsive... i tried to put back the original kext files.... and then i got a stalling splash screen... i used this line from xplode's guide (Thanks xplode): mv /var/db/netinfo/local.nidb /var/db/netinfo/local.nidb.bad ^ in darwin.. to repair it...

Marcp1967 Posted August 21, 2005 Author Share Posted August 21, 2005 Here is what I done, and get full screen to work. But I get some odd behaviour. Install the deadmoo image on my laptop drive. Installed SSE2 patches. 1)Open Terminal 2) sudo -s 3)password 4) open a finder window 5) Nvigate to System/Library/Extensions 6)in terminal, type cd and drag the first file with the name appleintel in it 7) add contents to your command so it looks like this example cd /System/Library/ExtensionsAppleIntel830.kext/contents 8)pico info.plist 9) ctrl+w to search 10) search for 2582 11) replace any instances of 0x25828086 with 0x25928086 12) Repeat this for all files called AppleIntel*.*, i.e. AppleIntel830.kext AppleIntel830GA.plugin AppleIntel830GLDriver.bundle AppleIntel915.kext AppleIntel 915GA.plugin AppleIntel915GLDriver.bundle AppleIntelIntegratedGraphics.kext (not some will not contain 0x25928086, but I don't remember which ones, so check and edit them all) 13)delete System/Library/Extensions.kextcache 14)Restart You may get the blue screen crash on restart. I also did this. But if I boted with platform=ACPI it worked fine. Although strangly if I chose to restart in the finder the reboot would give me the blue screen crash, but a shutdown would not. Hope this helps, it works for me, but your milage may very.

hatoncat Posted August 22, 2005 Share Posted August 22, 2005 This will patch the driver to view 2592 (which appears to be the mobile GMA 900) to work, but, it will not patch QE. QE support is built into the compiled portion, and so it will either work... or not.

If you are, you should try booting it with an external display. The first time I patched my kext files, I got a blue screen and thought my install was fubar, by as a matter of interest I booted with an external monitor and low and behold it started up. I really don't know why it's doing this...

lucose Posted August 22, 2005 Share Posted August 22, 2005 Hi guys, Finally, my HP Presario B1800 could load the GMA900 dirvers and working on 1280x768 32-bits resolution.

bsod Posted August 22, 2005 Share Posted August 22, 2005 I am using a laptop.. ill try to connect it to my 15" sony monitor.. and see where it goes.. i hope it works. <{POST_SNAPBACK}> there seems to be some problem with the drivers detecting laptop monitors everytime. sometimes after editing kexts etc, i can get QE and CoreImage to work at 1280x800 on my laptop but sometimes it hangs and blue screens. but after editing, i can hook up an external monitor and it will boot QE and CoreImage everytime no problem. im not sure why this is happening cause as far as i can tell the verbose output in -v mode is the exact same. i really hope someone knows why this is happening cause once i got QE and CI to work a few times, im obsessed with trying to get it every time and i really dont want to use an external monitor on my laptop.... bsod Link to comment https://www.insanelymac.com/forum/topic/715-toshiba-notebook-intel-900-gma-display-issues/#findComment-5633 Share on other sites More sharing options...
