I have HP Pavilion DV5-1050ep with:

Intel® Core™2 Duo T9400 2,53 Ghz
RAM 3072 MB
HDD 320 GB SATA
NVIDIA GeForce 9600M GT

When I try to install leopard (iatkos or leo4all) in my laptop, an error appears on the screen: "Still Waiting for root device"

Anybody know how to solve this problem?

regards

did you try to boot with cpus=1 -v? or with rd=disk0s1, if you have a backup partition and windows should be like rd=disk0s3

rd=disk0s1 <-- Hp partition
rd=disk0s2 <-- windows (if you dont have win, try this one)
rd=disk0s3 <-- OSX
