Hello,
This is regarding the issue on flashrom tool read error. When we try to read/write/erase the bios image by using the below command, we are getting the transaction error opcode 0x03 failed. None of the flashrom command were working. Flashrom -p internal:ich_spi_force=yes -r a.bin
Winbond chip: W25Q64, Rhel 6.0 OS, Please find attached the log.
Is there any patch available to unlock the ME region? Could you please help us to resolve this issue?
Thanks & Regards, Jayasree

Hello Jayasree,
We are working on unlocking it, but intel does not provide us any documentation so please do not expect a solution soon.
Flashrom can do partial writes (e.g. it could update just the BIOS region) by using layout files (see manpage). The problem is that there is no way for flashrom to tell if updating the BIOS region is enough or if that would brick the board. The reason is that the ME is a small embedded processor inside the chipset of the board that has full access to all components and different versions of its firmware (which is stored in the ME region) might require different versions of the BIOS and vice versa. You need to get that information from the mainboard vendor or use the vendor tools for updating, sorry.
Hi Stefan,
Thanks a lot for your immediate reply. We are using BIOS+ME region with the help of vendor tool.
From Flashrom tool, we are looking for Save/Update the NVRAM BIOS setting region, If it is possible could you please help us to provide the command?
What is layout file, how we can use it, is this solves our issue?
Thanks & Regards, Jayasree

the actual settings are usually saved in NVRAM and not in the flash chip so this is not in the scope of flashrom. you can find more information regarding this for example on this page: http://www.pixelbeat.org/docs/bios/
besides the linux kernel module mentioned there, there is also a tool named nvramtool that might be of use: http://www.coreboot.org/Nvramtool

a layout file is a text file that tells flashrom where different parts/regions/partitions should be, please read the documentation of flashrom before asking further question regarding this.
