Overview

PS2 contains one or two Mask-ROMs, "BOOT ROM" containing the BIOS and "DVD ROM" containing the DVD Player, with the latter being optional, since early PS2 consoles (SCPH-10000 and SCPH-15000, A-chassis) came with no DVD Player preinstalled. On these consoles, it had to be installed onto Memory Card from the Utility Disc bundled with the console. PSX also has no DVD Player in ROM; it's loaded from HDD instead. In many consoles containing a version of the DVD Player in ROM, it is physically located within the same ROM chip as the BIOS. Despite this, the DVD Player section of the ROM is electrically addressed independently and handled as a separate device by IOP. Other consoles contain two physically separate ICs. Many fat and early slim motherboards have solder pads for both variants and can have these installed either way.

BOOT ROM always has a size of 32Mbit/4MByte, while DVD ROM has a size of 16Mbit/2MByte until G-chassis (thus until SCPH-39XXX) and 32Mbit/4MByte from H-chassis onwards (thus from SCPH-5XXXX).

Only in the special Chinese SCPH-50009, there is an additional third ROM-partition, containing a Chinese font set. This ROM-partition resides in the physical DVD ROM IC, which is a 64 Mbit/8MByte part in these consoles.

The following sections are incomplete and work in progress!

Numbering

All BIOS and DVD ROMs have the version of the BIOS / DVD Player they store marked on the IC. In all consoles except A-chassis (SCPH-10000 and SCPH-15000), these versions are prefixed with a "B" for BIOS (e.g. B-20-030) or a "D" for DVD (e.g. D-221-030). On ROMs containing both, BIOS and DVD Player, both versions are printed separately on the IC. Instead of the dashes within the version numbers given in the examples, the writing can also have spaces, or no separator at all.

Fat consoles

For the BIOS ROM, the first digit defines the region (e.g. 0 for Japan, 1 for North America, 2 for Europe). The second digit defines the console type (e.g. 0 for Retail, 1 for Dev). For the DVD Player ROM, it additionally also defines the DVD Region Code (and PAL capability?). The second group defines the actual version.

BIOS Examples:
B-00-100: 0 = Japan, 0 = Retail, 100 = version (from a Japanese SCPH-10000 console)
B-01-100: 0 = Japan, 1 = Dev, 100 = version (from a Japanese DTL-H10000 console)
B-20-030: 2 = Europe, 0 = Retail, 030 = version (from a UK SCPH-35003 console)

Note: While Russian ROMs have the same BOOT ROM version labelled as their European counterparts, their actual content appears to be different. This is subject to further research.

DVD Examples:
D-020-020: 0 = Japan, 2 = DVD region code 2, 0 = NTSC only?, 020 = version (from a Japanese SCPH-18000 console)
D-341-110: 3 = Oceania, 4 = DVD region code 4, 1 = PAL and NTSC (however, region code must match)?, 110 = version (from an Australian SCPH-50002 console)
D-552-111: 5 = Russia, 5 = DVD region code 5, 2 = ???, 111 = version (from a Russian SCPH-50008 console)

Slim consoles

On slim consoles, numbering has changed a lot, since these consoles have multi-region ROMs for both, BIOS and DVD Player, which are patched on-the-fly by MechaCon depending on it's regional settings from EEPROM.

Known BOOT ROM versions

Fat consoles

Japan

  • 00-100
    • BOOT ROM of early SCPH-10000 consoles (A-chassis, GH-001)
    • Found in consoles manufactured until March 25th, 2000
    • Is the only version that does not block launching the buggy DVD Player 1.00 from Memory Card, which allows a region code check bypass
    • Contains the Protokernel, which lacks several features and has several differences to later versions, creating some issues with homebrew software
    • Comes in a different package with a much larger footprint than all other ROMs except 00-100 and 00-101
  • 00-101
    • BOOT ROM of later SCPH-10000 and and all SCPH-15000 consoles (A-chassis, GH-001 and GH-003)
    • Found in SCPH-10000 consoles manufactured later on as well as in SCPH-15000 consoles
    • Blocks launching DVD Player 1.00 from Memory Card
    • Contains the Protokernel, which lacks several features and has several differences to later versions, creating some issues with homebrew software

  • B-00-012
    • BOOT ROM of SCPH-18000 consoles (A+-chassis GH-003 and AB-chassis GH-008)
