| 1 | OpenWRT on the Sony PS3 Game Console |

| 3 | The OpenWRT build will create both a 1st stage PS3-Linux image |
| 4 | suitable for programming into the PS3 flash memory, and a 2nd |
| 5 | stage PS3-Linux image suitable for loading via bootloaders or |
| 6 | the kexec utility. |
| 7 | |
| 8 | The 2nd stage image is convenient for testing new builds. It can |
| 9 | be loaded from disk, USB device, or the network by an existing |
| 10 | Other OS bootloader. After the 2nd stage image is tested and |
| 11 | found to be good, the 1st stage image can then be programmed into |
| 12 | flash memory. It is recommended to use this method during |
| 13 | development to avoid corrupting the flash memory contents, which |
| 14 | requires a reboot to the Game OS to repair. |

| 20 | |
| 21 | The 2nd stage image file is bin/openwrt-ps3-vmlinux.elf. It can |
| 22 | be loaded with an entry in the bootloader config file. It has |
| 23 | no initrd file. |
| 24 | |
| 25 | The 1st stage image is named bin/otheros.bld. It can be programmed |
| 26 | into flash memory either from Linux or the Game OS. From Linux, |
| 27 | use the command: |
| 28 | |
| 29 | ps3-flash-util -w otheros.bld |
| 30 | |
| 31 | From the Game OS, use the menu item 'Install Other OS'. |

| 39 | and go to 'Kernel Options' -> 'Initial kernel command string'. |

| 41 | The default video behavior is to autodetect the monitor capabilities, |
| 42 | which should work for most monitors. More info on video modes can be |
| 43 | found in the man page of the ps3-video-mode utility. |
