Hi All..I have installed SL & I took pics step by step.
Machine: HP ProBook 4520s, 4GB RAM, 500GB HDD
Processor: Intel i5 M 460 2.53Ghz
Image Used: iATKOS S3 v2 (MD5 hash checked)
Installation successful with this boot flag: -v arch=i386 busratio=17

And when the Installation finished I rebooted my laptop with nawcom modcd.

Then selected my SL Harddrive and bootup with this Bootflag:
-v -f arch=i386 busratio=17

Following screen messages are attached as well. Pics are marked from 1-13 (as it happened).

I did not upload pics here as all pics are uploaded in another forum.

My Problem is very well documented here:
