Every PSP motherboard has an on-board flash chip that contains the PSP NAND image. That NAND image contains flash0-5 and the [[IDStorage]].
All motherboards has an onboard flash chip that contains the PSP's NAND image. That NAND image contains flash0-5 and the [[IDStorage]]. Also, the motherboard contains Tachyon, Baryon, Pommel, Kirk, and Spock. Here is an explanation of each:


*NAND - An image of flash0-3 and the IDStorage Keys of a PSP. It is stored on the onboard flash chip.
*Flash0 - Contains the PSPs Primary Firmware.
*Flash0 - Contains the PSPs Primary Firmware.
*Flash1 - Used to store the XMB settings, network configurations, the background image in FW 2.00 and above, and the Custom Theme in FW 3.70 and above.
*Flash1 - Used to store the XMB settings, network configurations, the background image in 2.00 and above, and the Custom Theme in 3.70 and above.
*Flash2 - In firmwares 3.00 and up, this contains the half of the DRM for Sony's official PS1 emulator (the other half being in the flash0)

*Flash3 - Used on development kits in firmware 5.00 and later to store kbooti.bin, kbooti is copied from flash3 to 0xBFE00000 (tachsm) by bootdispi.bin, about 1 MiB in size, It is used on retail units to store vsh specific applications such as 1seg. In custom firmwares it can be used along with flash2 to redirect firmware elements such as fonts. Also contains the Premium XMB Theme which is exclusively available on the MHP3rd PSP 3000 models.
