Note: I already have Os X installed on a disk image I am pulling over from my windows install.

sudo apt-get update
sudo apt-get install pearpc

copy files (hd image, video.x, nvram) to /etc/ppc directory
edit ppc.conf with the file paths as /etc/ppc/filename for each in conf file...

gksudo gedit /etc/ppc/ppc.conf

...if you don't edit this file you will recieve the error
"
test/imgs/linux.img: could not open file (no such file or directory)
"
I also edit the amount of ram to 512

memory_size=0x20000000

and also, set the cpu to g4

cpu_pvr = 0x000c0201

Make sure to "un" comment both of these values or PearPC will revert to defaults (128mb ram G3)

run pearpc
ppc ppc.conf

Next up, getting PearPC/OsX10.3.9 on the net using this info http://gentoo-wiki.com/HOWTO_PearPC#Configuring_Networking

Cheers!
