I have tried installing hackintosh on my hp pavillio dv7t for quite a while now and cannot find anything that works.

os x disc I have used:
Kalyway 10.5.2
iDeneb 10.5.7
iAtkos 10.6.2
hazard 10.6.1
Epire EFI 1.08
Rebel EFI

I have tried pressing F8 and loading all of these with the following commands:
platform=ACPI -v

I have also tried going into the advanced BIOS settings and changing things like I have been told. but I do not have those options as the hp bios is quite limited.
there are no advanced options in the HP bios at all.

my problem is I keep getting the errors:
"unable to initialize UIM"
"still waiting for root device"
