Also known as bootrom(on proto/DECR) or bootldr / Boot Loader ; see also: Dumping_Bootldr Talk:Dumping_Bootldr

lv0ldr (this may need some reordering with Boot Order as centralised reference):

  • Initialises I/O (IOIF0/IOIF1)
  • Checks CBE version
  • Checks Memory configuration
  • Checks flash format (1 or 1_1)
  • Checks sb_rom_base (South Bridge)
  • Initialises SS2_WORK (Starship2)
  • Initialises XDR RAM (And verifies with memtest elf - On SPU 0 - It's hardcoded to load there).
  • Checks eeprom_os_bank_indicator for active ROS
  • Authenticates + decrypts lv0 (which runs on PPU) from the active ROS -> loaders INIT
NEW consoles only: metadata lv0.2 (signed with nonrandomfail key) is used to check lv0 integrity
