i figured out that to boot the install cd you need to start with -v boot. once installed to get sound working sig9205 codec gets sound working with the volume control also working on front. unable to find a solution for the wireless if anyone can help. also shut down restart not working.

i just installed broadcom drivers from Iatkos v7 the onyl thing its good for is drivers though so dont try to install that cause it's not happening.
I could use help with my sound i cant get that to work also my computer cant sleep and it doesnt shutdown properly i have to wait for the screen to go black and then hold my power to turn it off.

I installed iATKOS v7 on my 1520 and almost everything worked. Only thing i had a problem with was video, i just booted in single user mode -s and at the command line removed the GMAX3100 kexts.right now i upgraded to 10.5.8 and every thing works, had to remove the gmax3100 kexts on reboot. Only problem i have is i only have 1024x768 resolution. its not the best, but everything else works. i'm currently looking for a snow leopard upgrade/install and i just found iATKOS S3 release so will test that out while this HacBookPro is still in the new freshly installed stages
