update:

with the injected "AppleNForceATA.kext.zip" i burned with transmac,
and tried now the suggestions from 'Possible solutions for "Still waiting for root device"' - thread, without luck :

Solution 1 - HDD is already on IDE primary [OK]
Solution 2 - tried, but [still waiting for boot device]
Solution 3 - already have an IDE drive [OK]
Solution 4 - already have an SATA optical drive [OK]
Solution 5 -
rd=0s0 [still waiting foor boot device]
platform=x86pc -v [still waiting for boot device]
platform=acpi -v [still waiting for boot device]
-f -v [still waiting for boot device]
-x -v [system stopped,num lock freezed, or i have to wait > 1h ?]

-----------------------------------------------------------------------------------------------

Do you have some other suggestions ?
seems with the injected AppleNForceATA.kext.zip it didn't work either.
with the original image - without injection, i had now the only success to install it,
but it didn't boot up.
Maybe i should also try those 1-5 solutions with cpus=1 ?

any help much appreciated.
