Hello George, thanks for your report! The problem is the locked ME region as quoted above. We are working on unlocking it or working around it, but intel does not provide us any documentation so please do not expect a solution soon (or ever). > Do you think that I will be able to read the memory using serprog and an > Arduino, unsoldering it from the motherboard or will flashrom just give the > same error? The problem is the configuration of the mainboard chipset. Outside of the board flashrom will definitely be able to read and write the chip (there is a minor problem of misdetecting the MX25L6405 because Macronix used the same ID for different chips, but there is a patch for that http://patchwork.coreboot.org/patch/3851/ and a quick hack that you could apply locally is just a simple number change). You might be able to access the flash chip while it is still soldered, so that you do not need to desolder it (completely), see http://flashrom.org/ISP If you need to read the BIOS region only, there is a complete software-based solution too. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Re: [flashrom] AMD - SP5100 - take SPI ownership (1/2)
by Rudolf Marek 02 Apr '13

Hi, Found chipset "AMD SB7x0/SB8x0/SB9x0" with PCI ID 1002:439d. Enabling flash write... EC SIO is at 0x16e EC MBOX is at 0x3e (Shutting down IMC) SPI base address is at 0xfec10000 This means that firmware correctly responded to the command and most likely moved itself to internal RAM. Verifying flash... VERIFIED. EC SIO is at 0x16e EC MBOX is at 0x3e (IMC resume failed!) This means that firmware was not able to continue at the end? I have a couple of questions: 1) did you perform full power cycle (even unplugging the PSU)? I suspect that the IMC may run even if main cpu is off. I also suspect it fully initializes only if performing this "cold boot". 2) what was the update? It was from original BIOS to coreboot? Does coreboot have a embedded IMC image? Does the IMC image start at the same location? What we could additionally check is if the IMC firmware location does not match in source and dest image, bail out. Or if the base addr has been changed. Thanks Rudolf
