Hi guys

I have a new 1520 I want to convert but it runs a Intel X3100 graphics onboard. So far I haven't seen any support for this, can anyone confirm? I'm going to try my luck over the weekend anyway.

Cheers

Here you go. I've attached a screen shot of my setup. Please let me know if that helped. I also attached my complete NVinjectGo.kext if you need it. I also wanted to make sure everyone knew that this is for a Geforce Go 7300 on a Dell E1505. Let me know if that was able to help you.

Howdy,

My E1705's 7900GS Go apparently went belly-up. I decided to replace the card and at the same time boost the power, so I got a 7950GTX Go off of eBay. I have the card installed, and XP64 seems to love it. However, OS X 10.5.1 seems to be less than thrilled. It begins to boot, the initial light blue screen comes up, and then.. it stops. The caps lock still works, so I know the laptop is "alive" but it seems to be stuck.

I am using the nvInject that is on one of the earlier pages, the modded one specifically for the 32-bit color banding on the 7900GS Go. I'm not in front of the laptop now, so I haven't had a chance to really mess with it, but just to streamline the amount of tinkering I do, can anyone recommend a way to resolve this crisis? I figure I'll just delete the nvInject kext and try the new .2.1 version, but I'm not sure if I need to do anything else special.

Note that the 7950GTX is a 512MB part, which OS X sees at boot as 256MB, and I don't mind this as long as there's no ill-effect. I don't do anything in OS X that requires that kind of video memory.

Haven't read through the 60 pages of the thread, however if the sleep problem to which you refer has to do with the display failing to re-initialize after lid-close or sleep, (or if anyone else is having such problem w/inspiron6400/1505), you can get the screen to come back on with this workaround (again, not sure if this has been mentioned yet):

-Open up the display preferences and tick the box for showing displays in menu bar.... Now it is accessible via kb shortcut (default <ctrl-f8>). So if the display won't revive, you can use kb shortcuts to select a new resolution easily. And when you do so, the screen will come back on... at which point just switch it back to your original resolution.

-Just memorize the arrow movements it takes to navigate to the resolution change. For me its <ctrl-f8,down,down,enter>, as display prefs is the first menu highlighted after <ctrl-f8>, but it might not be for you.

So, not the best solution, but the only one that's come to mind.

Quick question for my e1505/6400. I can install Iatkos 1.0ir2 successfully using efi only without the stock kernel (stock kernel just halts mid-boot, and I can't see an error to figure out what's up). The non-stock efi boot gets me in to the setup screens, but when I get to the point of having to fill in information, my keyboard doesn't work. I don't seem to see anyone reporting that problem here. The keyboard works when booting the Iatkos disk, so it doesn't really make sense to me. Any ideas? Thanks.

sounds like when you try to boot into vanilla kernel you don't have the correct AppleSMBIOS.kext installed. It will not work with vanilla AppleSMBIOS.kext.
The fact that the keyboard does not work is related to a similar issue in AppleACPIPlatform.kext. if you use the wrong one (eg. vanilla kext on a non vanilla kernel) then non of your ps2 devices will work, which includes the keyboard on your notebook.

altogether, it seems that you did not choose the correct combination of kernel and kexts when you installed.

nope, no dice. I tried sth similar before. nice idea but it doesn't work. thanks for trying to help! I think this works fro the 3100 or others, but not the gma950

Well it works when you CHANGE the display resolution, on my e1505 which is gma950
(Linux lspci says 00:02 ... 945GM/GMS, 943/940GML Express integrated Graphics Controller rev 03)
I have to choose 1024x640 then the picture comes back and I can now change it
once again to 1280x800.

So how do we fix this ??. I wonder if it is only the backligth that is not turned on. Would it be possible
to log into this system using ssh and turn on the backlight manually (to check if this is the case).

Where is this supposed to happen ?? and is the sourcecode available for this module, if so I would be happy to look into it.

PS: how do I easily get lspci (and other UNIX tools) for OSX

Can/Will the stuttering (with c2dm) be fixed? I want to get a Inspiron 1720 to use leo, but i'm not sure if i should after reading this guide

more here and here

I'm going to take a bet that it will be fixed eventually.

Only one person so far in this thread has actually spoken about trying to solve the problem; the last guy working on this (Prasys) has actually left the hackintosh scene. He developed the ACPI kext which we used for SpeedStep on 10.4.9, and he was planning on allowing full manual ACPI implementation for different systems, but no one (to my knowledge) has taken over from the project.

Someone else tried, but theres still no solution.

http://forum.netkas.org/index.php/topic,43.0.html

He hasn't posted in a while, might have stopped working on it.
I really doubt we will ever see a fix for it.

Dell BIOS does not export the HPET address through the ACPI tables. The reasoning is that Windows does not use HPET and so Dell doesn't want to add the HPET address into the table for fear of breaking something. So, why fix what isn't broken (except it is broken and has caused many headaches for non-Windows operating systems).

In a rush, but just thought I'd finally get around to posting this, a month later...

Instructions:

1) Delete existing AppleHDA.kext and ALCinject.kext files in /System/Library/Extensions

2) Mount image file and copy kext files into /System/Library/Extensions

3) Delete /System/Library/Extensions.kextcache and /System/Library/Extensions.mkext

4) Delete /Library/Preferences/com.apple.audio.DeviceSettings.plist

5) Run Disk Utility and repair disk permissions

6) Copy 'Play Thru for SigmaTel 9200' to the folder of your choice and use as necessary in order to hear input device audio via speakers



Some quick caveats:

- Only designed for E1705/9400, aka Dell laptops with subwoofers.

- Kext uses latest version of AppleHDA (early July update), so you must be running 10.4.10 for it to work. Users of 10.4.9 and below should not apply this kext.

- Subwoofer is now an independent device, so its volume is controlled separately, even if you don't hear it when it is selected in System Preferences. The trade-off with this is that you have to remember to mute both devices if you want silence, but the gain is that you will be able to modify subwoofer volume independently of the main front speakers.

- Headphone detection 'works'; headphone output does not. OS X insists on muting the mixer node (0b) entirely when a device is inserted, which goes against the Intel HD Audio 1.0 spec's exception for codecs with shared mixer nodes. However, Apple doesn't use any codecs in its current hardware lineups that have shared mixer nodes, so I don't expect them to make any attempt to support this portion of the HD Audio spec.

- For Play Thru for SigmaTel 9200 to work properly, the External Microphone device and both speaker devices must all have the same 'Format' settings in 'Audio MIDI Setup'. I've only tested it fully on 44.1kHz, 2 channel 16-bit output, since this is what the Dell specs are set at. If you have different bit-depth or sample frequency settings for separate devices, you WILL have problems with the output locking up after a few seconds.



Will write more later, but late for a Saturday night outing. Hope this works for all of you. I'll be back to check and see if there are any problems!



Cheers,

-T.

Ok, we have to organize a massive e-mailing action to dell for the next bios revision...

Oh yeah, good find. I think I saw some of his earlier posts a while back, shame he hit a brick wall

4:02pm Report abuse. HPET is not available in the chipset on all systems, and on a few older chipsets the feature was never enabled in BIOS or tested. In some instances, forcing the HPET on via the kernel will work, but it is not guaranteed to work. HPET is enabled and exposed by BIOS on most newer systems.

The audio fix does not work on the E1405 at all.

Look, i've post on ideastorm.com a petition for enable HPET on dell BIOS.. and i have a respond of dell staff of ideastorm.

This post is made to allow you VGA dual-screen full support with Nvinject 0.20 (found on this topic) and Go 7900gs.

-First step, check Properlist Editor
-Then, make a copy of your old nvinject on your desktop (or where you want).
-Open info.plist (inside NVinjectGo package) with Properlist Editor.
-Go to Root->IOKitPersonalities->NVinjectGo->entriesToAdd->NVCAP
-Change Value by this one:

-Save it, and replace nvinject with kextHelper (or command line).
-Reboot and enjoy.

I've not tested it with DVI port and tv out, but we're waiting for reports .

EDIT: Tested with DVI: OK

Alternative - Modified kext:

Any idea of this would work on a 7300go? I have a dell 6400.

Hey everyone. Been awhile since I've last been here, but just wanted to check in and say hello. It seems like a little progress is being made in different areas, so glad things are shaping up nicely.
...

Thanks for your patience with all this. I'm in the process of starting up a new company, so as you can imagine it's been rather hectic. I hope everyone is doing well and I look forward to what new developments may appear in this thread over the coming months.

Thanks for the info
BTW can you tell me where i can find info about the NvidiaGO 7800 256MB
I will be really happy with 2 screens

Thanks in advance
