# Apollolake
|
||||
## SPI flash layout
|
||||
|
||||
![][apl_flash_layout]
|
||||
|
||||
With Apollolake Intel invented another flash layout for x86 firmware called IFWI (Intel FirmWare Image).
|
||||
|
||||
Usually on x86 platforms the bootblock is stored at the end of the bios region
|
||||
and the Intel ME / TXE has its own IFD region. On Apollolake both have been
|
||||
moved into the IFWI region, which is a subregion of "BIOS", since it allows to
|
||||
store multiple firmware components.
|
||||
|
||||
The IFWI region can be manipulated by `ifwitool`.
