Leopard-AMD-10.5.1-Rev2 (Beta 1) - Beta Test Report and a Issue

Hello to all, especially to Zephyroth and all other Beta testers.

Here is my first impression of Zeph´s Leo-Builds Beta 1 (7.1) and Beta 2 (later in Jan). I firstly tested the Beta 2 but i cant get it work in any way. Ive tested all boot-flags alone and together. Nothing really worked. Then ive tested Beta 1 from first January.
This Beta worked, not out of the box, but with a Notebook Logitech Mice attached to one of my USB Ports. The 1 minute to go-issue at installation occured but i know how to workaround this
After that i remained the installation and it went all fine. At the first Boot the next error occured means: "System config file ´/Library/Preferences/SystemConfiguration/com.apple.Boot.plist´not found" <= Need Help with that!
i forgot: i installed with MBR.

I will attach some Screenshots in a minute which shows some Errors at Bootup (using -v and (-v -x)).

Here are my Notebook Hardware Informations:

HP Pavilion dv6130eu
AMD Turion 64 X2 TL-50 - 2x512MB DDR2-RAM - nVidia Nforce 4 Mainboard - 100GiG Seagate SATA-HDD...
and a Keyboard and Synaptic Touchpad attached.

Greets, Martin

PS: In hope the final 10.5.2 will be released very soon!

PPS: All Screenshots occured while booting the DVD (different Boot Flags)
