Hi All,

The problem I'm facing is that once kernel is loaded screen gets blank and nothing happens.

I've tried multiple ways of preparing USB key and booting kernel including:
- UniBoot
- MyHack
- iAtkos

Options I've tried so far:
- PCIRoot=1
- GraphicsEnabler=Yes / GraphicsEnabler=No
- cpu=1
- arch=i386
- npci=0x2000
- -f, -x -s flags
- "Graphics Mode"="1440x900x32"
- debug=0x144


None of them did not work and laptop seems to have pretty standard config and should work out of the box:

CPU T2250
Memory: 1GB
Video: GMA950
Screen: 1440x900
Model: Gateway MX8711
BIOS version:72.14, 72.11
Full spec: http://www.cnet.com/...7-32363010.html

I've successfully installed OS X on different laptop and even if faced some problems it at least gave me some errors. In this case I'm completely blind.

What's worth mentioning, this laptop has video output and I'm wondering if this is not the source of problem? If it could be, how can I force kernel output to be put on embedded LCD? I've checked attaching external display on VGA connection but nothing was displayed there neither.

Any help will be highly appreciated.


Thanks,

Still no results with problem as per earlier description.
One step forward for me was that I was able to install 10.5.8 using iAtkos v5 as per description posted here http://www.insanelym...howtopic=223589

Does any of you know where the problem is with Lion?
I've tried to upgrade to 10.6 or 10.7 from 10.5 but I'm getting "this system can not be upgraded" :(

Any help would be appreciated.

Thanks.

For records, trying further with different releases I've found out that iAtkos S3 v2 boots fine up until installer prompt. I'll see later if installation will be successful.
