Ist wohl so eine Art Bootloader
installing
1. Put your otheros.bld file on to a USB disk, in a file called /PS3/otheros/otheros.bld. Assuming your USB disk is mounted at /media/usbdisk:
[jk@pokey ps3-kboot-0.1]$ mkdir -p /media/usbdisk/PS3/otheros
[jk@pokey ps3-kboot-0.1]$ cp otheros.bld /media/usbdisk/PS3/otheros/
If you don't have a USB disk, you can use any sort of media that the PS3 can read - CDROM, DVD, compact flash, etc. Just make sure that the file is called /PS3/otheros/otheros.bld.
2. Plug the USB disk into your PS3, and navigate to System -> System Settings -> Install Other OS. The PS3 should find the new file on the USB disk, and install it.
3. To boot with petitboot, just set your default operating system to "Other OS" (System -> System Settings -> Set Default OS), and reboot.
Viel Spass !!!!
