PS2 contains one or two Mask-ROMs, "BOOT ROM" containing the [[Bios|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 without 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/Deckard|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-390XX) and 32Mbit/4MByte from H-chassis onwards (thus from SCPH-5X0XX).

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.
