1 post in this topic

Recommended Posts

Hi everybody, yestarday I was searching how to install Snow Leopard on my HP dm4 1280la, the specs will be at the end oh this post. Now, hours ago, I burned 3 BootCD's: 1 ######, 2 Empire EFI v1.085, 3 Nawcom Boot. The thing is, I've tried every Boot CD and these are the results:


1 ######:

Starts normally, when I swap the disc for the SL DVD there is no problem.

Starts to load the Gray wallpaper from the installer, and suddenly shows a message:


"Please shutdown your computer by holding down the power button until the screen turns off"

Something like that. and, I've tryed one and one again, with no results.



2 Empire EFI v1.085

Starts normally, when I swap the disc for the SL DVD there is no problem.

When I hit enter to boot from SL DVD this is what is on the Screen:


No DSDT found, using 0 as uid value

Loaded HFS+ file: [Extra/smbios.plist] 416 bytes from 42521f0

Patched DMI Table

No DSDT replacement found. Leaving ACPI Table as is

Starting Darwin x86

Press any key to continue

And when I hit any key, it just reboot normally and DONT BOOT to the Snow Leopard DVD.

I've tryed by typing:

-v rd(0,0)/Extra/modbin_kernel

and still do the same.



3 Nawcom BootCD

It does the same like Empire Efi


Please Give me some Help! I want to install it.

Thanks by reading.
