I am in the same boat. My computer was just sent back from AppleCare and they finally replaced my defective logic board but now I have 'NO' serial number of any kind. I have been fighting with them to fix that or let me fix it, and here is what I have found.

The serial number is stored in NVRAM in OpenFirmware. Data is written to the NVRAM memory chip by going to the OpenFirmware prompt, entering your new commands and then 'nv-update'. The problem is finding a command (if one actually exists in OF instead of needing to write into a config file and then run it) We need to find a really great Linux Kernel Developer with strong experience with Proc to find out where it looks up the system serial number from. Correct be if Im wrong, but isn't the serial number the Mother Boards serial number as well? If so, then it can't be changed without getting a new MB This is the problem we are trying to get around. Change the serial # without having to change the motherboard.

I was recently reading some other posts where it was reported that the serial changed when they replaced their hard-drive. Could this be possible? Is it possible that the serial is a combination of hardware serial numbers? Can anyone confirm this? Or is it just a number assigned to a motherboard NVRAM? Does anyone know if this dmg will still change the serial number on the newest macbook pro's? The one's with the 2.4 ghz processor?

I have a 17 inch model and when I press and hold the D key when booting, it will not boot from the cd. I've tried putting in other bootable cd's and holding ALT/option and that cd shows up (bootable Leopard install disc). I also want to mention that I had an older version Macbook Pro (2.33ghz) and it ran the cd just fine and I was able to change the SN. I'm just kind of wondering if it's a hardware issue, or firmware.and if anyone else has had any luck changing a serial number on the newest macbook pros.
