    Hi, I'm interfacing a microcontroller to the Serial Presence Detect
    (SPD) lines on a 144-pin SO-DIMM of PC133 RAM. I understand it uses I2C
    and it's just an EEPROM, and I have the read commands all setup, but
    what I can't seem to figure out is how to find the device address. The
    EEPROM is the only thing on the i2c bus (aside from the microcontroller
    of course). I've never used i2c before, so forgive me if this is a very
    obvious question. Thanks!
