Windows 8 and 10 weren't tested and you may have issues on using FPT due to possible additional protection mechanisms in kernel. Windows 7 圆4 Professional is recommended because it is guaranteed to work when following this guide. The command examples in this guide will be given using fptw64.exe which is a FPT executable for Windows 64-bit on Linux the executable is named FPT thus should be called like. Windows 7/8/10 _OR_ Linux in case you have ME >=12 Now, be sure you have the following in order to follow this guide: You could also do this on DOS or UEFI since FPT is available for them, but they won't be described here to avoid any confusion. However it's recommendable to use Windows to follow this guide because a) all FPT versions are available for Windows b) avoiding any kind of headache related to compatibility/complexity.

There are some attempts to make a software flasher like, but there is nothing specific and universally usable.įPT is available for Linux starting from versions 12 only, in case you have this ME version or higher you could try to perform everything described here on Linux. Logically thinking, why would we use FPT when flashrom on Linux could provide same functionality via -programmer internal? Unfortunately it still doesn't support intel_spi ( description on ) which is a module used on Linux to provide the PCH SPI access. Unlocking FD or/and ME section provides a better overview of some common methods.

Some desktop motherboards have a physical jumper that could be tagged as 'Service Mode', 'FD/Flash/Security Override', 'FD Unlock', 'ME/TXE/SPS Unlock', 'ME/TXE/SPS Service', 'Manufacturing Mode' or similar, making full flash memory access facilitated, but laptops do not have such jumpers and rely on something simulated, such as a pin on Intel High Definition Audio codecs to enable a servicing mode. Intel platform development guides for OEMs often mention 'Flash Descriptor Security Override' or 'Intel ME Debug Mode' ('Service Mode' on Dell hardware), that could be enabled via different ways depending on the manufacturer. Intel also have some security override methods in its platforms specifications for OEMs. firmware rootkits), however it's possible to disable write protection using various servicing modes often provided by manufacturers.

Usually most of those regions are not available for write for security reasons (e.g. The information stored in the Flash Descriptor can only be written during the manufacturing process as its read/write permissions must be set to Read Only when the computer leaves the manufacturing floor.įlash Descriptor contains AltMeDisable or High Assurance Platform (HAP) bits that disable Intel MEĪll these regions combined is a full flash memory available directly from OS. The maximum size of the Flash Descriptor is 4 KBytes. The descriptor is on the SPI flash itself and is not in memory mapped space like PCH programming registers.

The Descriptor data structure describes the layout of the flash as well as defining configuration parameters for the PCH.

The Flash Descriptor is a data structure that is programmed on the SPI flash part. Winbond W25Q64FV) in a same way as using external programmers, providing the ability to read and write the following flash parts: Asserting HDA_SDO HIGH on Intel High Definition Audio chips ( >= 6 chipset series )įPT is able to access the flash memory chips (e.g.Determining whether the Intel Boot Guard is enabled.Neutralizing Intel ME via internal flashing with Intel FPT
