Hi all, 
  
I have been trying to install Snow Leopard 10.6.3 on my Dell D620 for a couple of days now, and I wanted to share my results: 
- SPECS: Intel Core Duo T2300 @ 1,66Ghz, 3 GB RAM, GMA945 video, Dell WLAN, 80 GB harddrive. 
- BIOS: disabled FIR, cell phone, serial and parallel (don't need it anyhow, set graphics to internal only)  
- OSX: 10.6.3 snow leopard retail DVD (original). Made .dmg image with TransMac (great tool!) and formatted a 16GB USB stick with that image (also with TransMac) on a Windows machine 
- MOD: NAWCOM V0.3.1 boot with external monitor disconnected and USB inserted (so it is recognised as bootable OSX install image) 
- start boot from OSX image with following flags to prevent kernel panic: mach_kernel platform=X86PC ACPI=off CPUS=1 
- wait until screen turns black and connect external monitor 
- partition disk in 2 partitions with Disk Util, format 1st partition with label "Macintosh HD", leave 2nd partition untouched 
- customise nothing and install OSX: wait 30 minutes. 
  
Now it becomes strange: 
- the very 1st try I got OSX running, with default graphics 1024x768, everything seemed to work (wireless, sound, mounting, etc.) 
- I installed a GMA950....pkg for snow leopard which broke the graphics (both on the laptop display & the external monitor) 
- No problem I thought, I just re-install and choose another kext for the graphics, BUT.....\ 
  
Now, when I restart after a fresh install I see NOTHING, neither on the laptop screen nor the external monitor (sometime a gray screen on the external monitor and a mouse), but I hear the 1st boot music, and I know what it expects me to do (choose a country of origin). 
I can't seem to get past this problem. What I've tried so far: 
- install W7 -> graphics work just fine (everything works fine) 
- install IPC 10.5.6 PPF5 with GMA950 kext selected -> graphics work just fine, everything I tried worked just fine 
- tried boot flags like "Graphics Mode"="1440x900x32" -> no result 
- booted -s and tried to edit com.apple.boot.plist to add graphics mode key, but in single mode the file system is read-only, I don't know how to edit this file. 
  
Can anyone please help me with this, it is driving me crazy. I have seen this work, and that is the frustrating part, I cannot get it to work again. Is there a way to install the GMA950 kext prior to 1st boot? 
  
All help is highly appreciated!
