Thank you very much for your response. I will check the link and hope to manage and enable it. One last question: if a board recognizes a 512kb chip is it normal to not recognize the above described ( SST 49LF008A ) 1Mb chip ??? I have a board with which i could do the flash procedure, it is fully supported by flashrom, flash chip, chipset, board, but it doesn;t seem to find the chip i want to flash. The original 512 Kb chip it's listed when i run flashrom, but when i change chips with the 1Mb one and run again flashrom the new chip it's not recognized...
