You're welcome! Ethernet i patched myself according the information found here. Thanks to all guys involved...
... By the way - you helped - thank you for that. You pointed me to the working Ethernet kext, which I can load from either boot-132 or Chameleon, and also works on my D630.
I like D620, it's almost perfect. That's why i want to make it 99% working.
For nVidia graphics that's very simple with the new Cameleon RC2.
With minor modification, I think it will work for D620 and D630 with NVIDIA graphics, not that you seem to need it.
You need to remove all GFX strings from boot.plist AND remove all injectors; then put autodetection flag: GraphicsEnabler=Yes
For me this works perfectly.
Not everything, unfortunately.
Sounds like you've got things under control. Now with Dual core support for 10.5.8, it's a beautiful thing.
One thing more I want badly: to figure out how to enable AHCI. I know D620 supports this. But Dell decided to strip the switch from the BIOS (obviously because of peoples' complains about crashing Windows after they switch to AHCI to cut down service-calls amount )
I'll let You know if this succeeds.
