i've tryed but dont work. i've tryed with:

-v -x -f
"kernel cache"=\amd
arch=i386
platform=acpi or osx86
fsb=200000000
dsdt=yes

and... with original mach_kernel of niresh lion, pc reboot automatically after bootcd. with niresh on usb i'ts different because i've change mach_kernel with mach_kernel V4, and with this dont reboot, but i'm get error of acpi
unable to find driver for this platform

this error is for niresh lion and hazard snow leopard and retail snow leopard, i remember "monts ago" i've intalled iatkos V7 leopard without more problem, but only there. any other distro report this error, this fu...d error!!!!
