However, it will access serial 59 - EEPROMs on any I2C adapter. The supported devices are generically called 60 - 24Cxx, and are listed above; however the numbering for these 61 - industry-standard devices may vary by manufacturer. 62 - 63 - This module was a programming exercise to get used to the new project 64 - organization laid out by Frodo, but it should be at least completely 65 - effective for decoding the contents of EEPROMs on DIMMs. 66 - 67 - DIMMS will typically contain a 24C01A or 24C02, or the 34C02 variants. 68 - The other devices will not be found on a DIMM because they respond to more 69 - than one address. 70 - 71 - DDC Monitors may contain any device. Often a 24C01, which responds to all 8 72 - addresses, is found. 73 - 74 - Recent Sony Vaio laptops have an EEPROM at 0x57. We couldn't get the 75 - specification, so it is guess work and far from being complete. 76 - 77 - The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional 78 - software write protect register at 0x30 - 0x37 (0x20 less than the memory 79 - location). The chip responds to "write quick" detection at this address but 80 - does not respond to byte reads. If this register is present, the lower 128 81 - bytes of the memory array are not write protected. Any byte data write to 82 - this address will write protect the memory array permanently, and the 83 - device will no longer respond at the 0x30-37 address. The eeprom driver 84 - does not support this register. 85 - 86 - Lacking functionality 87 - --------------------- 88 - 89 - * Full support for larger devices (24C04, 24C08, 24C16). These are not 90 - typically found on a PC. These devices will appear as separate devices at 91 - multiple addresses. 92 - 93 - * Support for really large devices (24C32, 24C64, 24C128, 24C256, 24C512). 94 - These devices require two-byte address fields and are not supported. 95 - 96 - * Enable Writing. Again, no technical reason why not, but making it easy 97 - to change the contents of the EEPROMs (on DIMMs anyway) also makes it easy 98 - to disable the DIMMs (potentially preventing the computer from booting) 99 - until the values are restored somehow. 100 - 101 - Use 102 - --- 103 - 104 - After inserting the module (and any other required SMBus/i2c modules), you 105 - should have some EEPROM directories in ``/sys/bus/i2c/devices/*`` of names such 106 - as "0-0050". Inside each of these is a series of files, the eeprom file 107 - contains the binary data from EEPROM.
