Only the VGA port is supported, no DVI. Simply connect the monitor, it should be detected. If not, just go to the Monitor Pref Pane and click "Detect Monitors" button. Do not select port mirroring, it's not working properly and you'd get both screens going all garbled.

Ok, but that is not sustainable because that is safe mode. We need to identify the kext causing startup to fail and fix the issue.

Follow the EDP documentation to the letter. That should get you through without hiccup.

We should be able to get past that issue by finding the right Chameleon option or flag. I can suggest to try various combination of the following boot options: PciRoot=1 USBBusFix=No/Yes npci=0x2000/0x3000 GraphicsEnabler=No/Yes Use them along -v flag to monitor startup messages. Did you go through the various Optiplex 745 threads that were created last year?

Now that you mention it, one of the D630 that I very rarely use does indeed have a faint but regular HDD click. It's a Seagate 160Go 7.2k rpm unit. I have Hitachi 80Go in others but I have not noticed anything that bothered me. I'm using an SSD in my daily Hack, so no noise at all...

??? I mustn't have the same system...

Please look-up the compatibility chart + bootpack table in EDP pages of the web site. These indicate what is supported and if it's not listed, it's not supported.

Oh, you really chose complication... Forget any decent graphics under ML on that model: there is no graphics support, there are no kexts at all, there is no acceleration, nada, ziltch. No, you can't add an nVidia GPU, you can only buy/get a D630 fitted with one at factory. No, there is no EDP support for ML on that model, hence why you can't run EDP on it under ML. Browsing is slow, video unwatchable, opening/minimising/closing windows is slow, there are video artifacts most of the time (minor and sometimes major), games unplayable, etc, etc. Graphics painfully run off the CPU and as such affect overall system performance. To me, it's just not sustainable to run unless you like to say you have ML on the system but not actually use it; I don't see the point, but maybe that's just me... Again, I can only recommend to stick to Lion. I've uploaded the complete necessary Extra folder. Use it as indicated if you're a non-believer, but please, no more requests for ML on that D630 X3100 system. It's not supported and does not run properly, plain and simple.

Read my answer in other topic re: reported 8400m GS card -> replace DSDT with version from boot pack will restore report of NVS 135m. I have exact same version/ROM/revision of nVidia NVS 135m as you:

Yes, many systems do that with ML... -> https://osxlatitude.com/index.php?/topic/1852-1082-update/ You use DDR2-400? That'll slow things down... Didn't even think it would be accepted by the laptop. You really should use DDR2-667 or DDR2-800.

If your top menu bar is translucid, you have graphics acceleration as expected. Try a green/purple desktop background to verify this, it'll be more visible than with a blue or grey background. The DSDT installed after EDP has been run does indeed change reported graphics card to 8400GS. If you re-instate the DSDT from the boot pack, you'll get NVS 135m reported back. It's one of those little things we have to fix in EDP, but it's trivial as only cosmetic. Now, ML does run a bit slower than Lion and quite slower than Snow Leopard on these machines. That's just how it goes, ML is much more demanding on resources. I'd say the minimum should be a T7500 with best performance with a T8xxx or T9300/T9500. DDR2-800 also helps. The Dock in SL was not transparent but acting like a mirror showing reflection of icons and windows/desktop background above it. That effect has been modified under ML, where it'll reflects icons a tad dimmer and windows above it only create a vague hint of a shadow. That's just OS X evolution...

Tjmax of both T7100 and T5600 is 100°C. You should therefore check the contents of the plist file of your /Extra/IntelCPUmonitor kext as the default Tjmax value is 0. You'll get incorrect (lower than real) T° readings with an incorrect Tjmax value in the kext. I have nothing specific to performance in terms of kexts in my /E/E folder, it's just the EDP-installed kexts, including TSCsync. So, if you have a myHack/EDP installation, you have the same as I do. I just have better T7500 CPUs (bigger cache, higher freq.).

Well, for those who really insist on trying and make their own evaluation of ML without graphics support... D630-X3100_ML_Extra.zip The included DSDT is LoRes/WXGA version. Change for HiRes/WXGA+ as required. Copy/move the PStateMenu plist to /Library/LaunchAgents for SpeedStep emulator app to auto-load.

Tried to boot with PciRoot=1 ? What add-on graphic card did you have before removal? nVidia kexts should be available off kexts.com (I know NVEnabler is).

No experience with the D820, but your D630 should not feel sluggish. Is SpeedStep working Ok? what CPU in those laptops? Regarding T° readings, they look terrific but suspiciously low for a D630 with nVidia GPU. Did you set your Tjmax to the correct values in the plist file of /Extra/IntelCPUmonitor kext? For a T7500, Tjmax is 100°C and other CPUs may have a different value -> refer to ark.intel for the correct values. My D630 nVidia never reports CPU T° lower than low-50s and GPU T° lower than high-70s... And all that despite a thorough cleaning, renewal of thermal paste + copper shim on the GPU.

'just had a look at the specs: mini-tower, desktop, small form factor (SFF) and ultra small form factor (USFF). All based on the same underlying specs: Pentium 4/Pentium D/Celeron or Core (Solo? Duo? 2 Duo?) CPU Intel Q965 Express chipset (which I understand supports C2D CPUs) DDR2-533/667 only for USFF model (vs. 533/667/800 for the others) Intel GMA3000 integrated graphics (with no apparent discrete card capability for the USFF model), which I understand to be different from HD 3000 integrated LAN card of unspecified origin (would need PCI vendor id + device id to fully identify) ADI 1983 HDA audio SATA 1.5 & 2.0 controller (believed to be ICH8) So the real items to look for are GMA3000 graphics support (may work with GMA950 kexts as GMA3000 is built on GMA900 & 950) + ADI 1983 audio support (I understand this to work with patched AppleHDA or maybe VoodooHDA). LAN support can be secondary or non-issue if add-on wireless card is used. The rest should be a no brainer.

It's the IOATAFamily kext, which clearly needs to be added to the bootpack. I put a fresh copy of it here: https://osxlatitude.com/index.php?/topic/2103-sata-not-visible-during-install/ It simply needs to be added to /Extra/Extensions folder of the myHack installer, followed by myFix, prior to OS X installation. One of the key items is the graphics support, depending on what you use: integrated hardware (is it HD3000?) or discrete add-on card.

If you simply add the kext to /Extra/Extensions folder of your installer, just run myFix on the media afterwards so that permissions & cache are properly rebuilt.

Ok, that's something different. It's on the Optiplex 745, right? There are a few posts about Lion installation on that model from last year. Have a look there for guidance (in Dell Desktop section).

Pretty much the same machine, mainly different screen size.

Well, GMA950-based D620 and D430 do wake from sleep. But they require a BIOS system password (+ password bypass on wake) to be set or they will KP on wake! You could try that. I'd say it's likely to work on the Dell 1505.

Looks like it: https://osxlatitude.com/index.php?/topic/2013-dell-optiplex-745-ultra-small-form-factor/ Give us your specs, then we'll see...

You could try, or check the boot plist of the bootpack to see if it contains that EFI string, in case it goes amiss after EDP is run.

Try and get a copy of IOATAFamily kext added to /E/E. Make sure the plist of AppleIntelPIIXATA plugin covers ICH-8, or whatever controller your D830 has, but I'd expect the same as the D630. In fact, try the attached... IOATAFamily.kext.zip

That set of kexts looks Ok. The only thing I can think of is that you're using Lion 10.7.5 directly, not a previous release like 10.7 or 10.7.2. I have no personal experience on installing 10.7.5 directly on a D830, just with 10.7.2 which I then updated to 10.7.5 (this worked Ok). However, I have seen several people experiencing difficulties installing Lion versions greater than 10.7.3. Or maybe it's not a full retail version. I did not even know Apple offered Lion 10.7.5 as a downloadable version; well I certainly haven't seen Lion available for download for quite some time... I'd advise you to try installing a different version of Lion, but I guess you probably don't have that. Let me check which kexts is used for SATA controller and we can check if it's there or loads on your system.
