installing problem on intel Q6600 (Could not validate the contents of the 10.5.5.)

[ariesto]

Hi

i have the following system :
Q6600 2.4 Ghz
Gigabyte GA-P35C-DS3R
Nvidia 7900 Gt 256 MB
Sata 500 WD
Run the Disk utility and make partitioned

Operating Systems : iATKOS v5i - Mac OSx86 Leopard 10.5.5 Intel DVD
Burned it with the slowest speed. I havent done the MD5 Checksum

Bootloader - PC EFI V9
X86 Patches - Decrypters - AppleDecrypt
- SMBIOS drivers - SMBIOS Enablers - AMBIOS EFI (its for desktops. EFI Air for laptops)
- Kernel - 9.2.0 Kernel ToH (should work fine I think)
- ACPI - X86 ACPI (just to be safe)
- Disabler.kext
- Remove PowerManagement.kext
- Remove Thermal kexts
Drivers - select the Graphics Update plus the drivers for your card.
System - SATA - select the one for your HD
-
- Network - well, I would select all of them in case you change the LAN card or something.

During the installation, around few minutes after installing
"it's failed and it written like this " Could not validate the contents of the 10.5.5.Intel package"

Any suggestion of what would the error would be ?
Anything to do with Quad Core?

Please Advice
