Remastering Debian Netinstall CD for PS3

From PS3 Developer wiki
Jump to: navigation, search

Introduction[edit]

  • Unfortunately, we cannot use official Debian netinstall CD with PS3 OtherOS++ because of the vanilla ps3disk HDD driver.
  • We have to modify it and replace the Linux kernel on the netinstall CD with our PS3 Linux kernel.

Remastering[edit]

Type This
mkdir netinst
cd netinst
 
losetup /dev/loop1 ./debian-6.0.5-powerpc-netinst.iso
mount /dev/loop1 /mnt/iso
 
cp -r /mnt/iso /root/netinst/
 
ls -l iso/install/powerpc64/
