The PlayStation 2 BIOS landscape spans over a decade of hardware revisions, from the launch "ProtoKernels" to the final "Super Slim" models like the SCPH-90006. While the community often seeks a "complete set" for maximum compatibility in emulators like PCSX2, the SCPH-90006 UPD is a specific variant noted for its region (Hong Kong/Asia) and its patched internal software that notoriously blocked certain older softmods.

Introduction
The PlayStation 2 (PS2) is a legendary gaming console that was released in 2000. One of the essential components of the PS2 is its BIOS (Basic Input/Output System), which is responsible for initializing the console's hardware and providing a interface for the operating system.
What are PS2 BIOS files?
PS2 BIOS files are firmware files that contain the console's BIOS. These files are used to update or replace the existing BIOS on a PS2 console. There are several PS2 BIOS files available, each with its own unique features and compatibility.

Important notes:
The PlayStation 2 (PS2) BIOS is the vital system software required by emulators like PCSX2 and AetherSX2 to execute game ROMs. The BIOS recreates the internal hardware environment of the original console, initializing settings and handling region restrictions.
While classic BIOS versions like the SCPH-10000 or SCPH-70012 cover common Japanese and North American titles, the newer SCPH-90006 (China/Asian region) is highly sought after for maximum compatibility with later revisions, specialized Asian regional discs, and homebrew stability. The Evolution of PS2 BIOS Models and Regions
Every physical PlayStation 2 console was manufactured with a specific BIOS version baked into its motherboard. To run specific regional game backups seamlessly, your emulator's BIOS must match the region of the game ISO/CHD you are playing. SCPH1000: This was the first PS2 BIOS file, released in 2000
[Game ISO/CHD Region] ───> Matches ───> [PS2 BIOS Region] ───> Successful Boot The core regional releases include:
NTSC-U/C (United States & Canada): Optimized for North American releases running at 60Hz.
NTSC-J (Japan): The original architecture used for initial Japanese releases.
PAL (Europe, Australia, & Oceania): Configured for European releases running at 50Hz.
NTSC-C (China / East Asia): Highly specific firmware configurations for exclusive regional releases. Complete PS2 BIOS Models Catalog
The SCPH-90006 specifically refers to the final hardware revisions released primarily in the Asian (Hong Kong/Singapore) market. While the SCPH-90001 (US) and SCPH-90002 (EU) are well documented, the 90006 region carries unique significance for preservationists.
The "UPD" (Update) designation in BIOS archiving often refers to a specific revision of the ROM chip soldered onto the motherboard.
Why the SCPH-90006 Matters:
Below is the master list of all known PS2 BIOS revisions, categorized by hardware series. The “new SCPH-90006 UPD” appears at the end of this timeline.
For the emulation community, the PlayStation 2 BIOS (Basic Input/Output System) is the DNA of a console generation. While ROMs represent the body of a game, the BIOS is the soul—the set of instructions that tells software how to speak to the hardware.
For years, the standard archive for enthusiasts and preservationists has been a collection of files ranging from the early Japanese launch units (SCPH-10000) to the ubiquitous "fat" and "slim" models of the West. However, the complete spectrum of this hardware timeline has often been missing its final chapter—until now. The recent inclusion and update of the SCPH-90006 BIOS marks the definitive end of the PlayStation 2 era, representing the last breath of Sony’s legendary sixth-generation hardware.
A comprehensive PS2 BIOS collection is not a single file; it is a timeline of hardware evolution. Each file, identified by its SCPH number, represents a specific manufacturing run with unique boot sequences, DVD player versions, and security patches.
The SCPH-90006 was the last model sold in Southeast Asia and Hong Kong (NTSC-J region). In late 2009, Sony issued a silent hardware revision to the motherboard (Rev 13), which included a mask ROM BIOS update that could not be overwritten.
To ensure a valid BIOS for emulation or research, verify the following:
