Install and Setup a NFS Server
Your /etc/exports should look like this:
Change the IP scheme and path to fit your configuration.
Make the /mnt/nfsroot directory and copy the image.squashfs (from a LiveCD) into it:
mkdir /mnt/nfsroot cp image.squashfs /mnt/nfsroot/
Then extract the squashfs as root by doing:
Now copy everything from the squashfs-root folder to /mnt/nfsroot by typing:
cd /mnt/nfsroot/squashfs-root && cp * -vaR /mnt/nfsroot
Alternative: Debootstrap a fresh powerpc system (debian/ubuntu) and use it as NFSroot.
Let the nfs-share re-export with:
Compile the kernel that you want to use
Get the kernel sources
You can get them from kernel.org 22.214.171.124 at time of writing (in the future this might change)
Get the patches and the kernel config
You can get them from here.
NOTE: At the time of writing v0.11.1 was the latest. Make sure that your kernel config and your patch are the same version.
Extract the kernel
With the following command:
tar -xvjf linux-126.96.36.199.tar.bz2
Patch the kernel
With the following commands:
cd linux-188.8.131.52 # assumes that the patch is in the directory above the kernel folder that you just changed into patch -p1 --dry-run <../patch-184.108.40.206-xbox0.11.1.diff # if the dry-run didn't show any errors do the following: patch -p1 <../patch-220.127.116.11-xbox0.11.1.diff
Copy and Edit the kernel config file
Copy the kernel config to the extracted linux-kernel folder:
# The '.' in front of the filename is there on purpose! cp /path/to/xenon-config /path/to/extracted/linux-18.104.22.168/.config
Look for a line similar to this:
CONFIG_CMDLINE="root=/dev/nfs video=xenonfb nfsroot=192.168.1.100:/mnt/nfsroot rw ip=dhcp panic=60"
Edit the NFSroot to be your IP address and adjust the path correctly.
Alternative: Use kboot.conf to pass a custom CMDLINE to the Server. If you want to do this you set:
Build the kernel
Do the following:
make ARCH=powerpc CROSS_COMPILE=xenon- menuconfig
Load up your config file that you just edited and then exit and run the following command:
make ARCH=powerpc CROSS_COMPILE=xenon- all
You might get an error if so you might need to edit arch/powerpc/kernel/pci_64.c line 149 and change the lh to llh both occurrences.
Rerun the last command and you should have a kernel. It will be in arch/powerpc/boot/zImage.xenon
Configure Xell to boot from your computer via tftp
To do this you need to recompile Xell. I assume that you already have a toolchain, I used the one from libxenon. You will need to edit the Xell source file network.c changing the default IP address to your IP address. Then compile Xell.
For Gentoo and 'atftpd' just type:
emerge -v atftp
Then edit the atftp config file:
I changed mine to look like this:
just edit this line and leave the rest the way it is as it is already correct.
For Debian/Ubuntu use the following: Instructions (Sections: Set up DHCP server and Setup a TFTP server
When done with that make the matching tftp directory (if it doesn't exist already) and put your linux-kernel into it, rename it xenon.
NOTE: XeLL assumes a path like /tftpboot/xenon in its standard configuration. If your tftp-daemon has a path like /var/lib/tftpboot/ set up you need to make a subdir tftpboot in there. Final path would look like:
Now if everything worked correctly you should be able to boot your 360 via NFS.
NOTE: It's recommended that the TFTP-Server is the one who serves the DHCP Responses and no other DHCP Server is in your network so XeLL can find the TFTP Server Adress.
NOTE(2): it is also possible to do this without a (linux) dhcpd server setup, using a router if you have a router that supports it (ddwrt, cisco, possibly some residential grade routers) by forwarding all tftp requests to your tftp server.
for ddwrt: enable DNSmasq
Go to your Web-Interface and log in Go to Setup->Basic Setup Make sure that DHCP Type = DHCP Server DHCP Server = Enable Use DNSMasq for DHCP = Checked Use DNSMasq for DNS = Checked
Go to Administration->Services
LAN Domain = <lan-name> DNSMasq = Enabled Local DNS = Enabled
in DNSmasq additional options:
domain=lan-name-here local=/lan-name-here/ expand-hosts dhcp-option=66,"tftp-server-address-here"
Or edit /tmp/dnsmasq.conf with the correct settings (the above settings) adding cisco conf next
