Re: serial numbers on new motherboards
Hi Sridhar! I didn't know you were getting bare motherboards. Reuben should have some scripts and recommendations as to how to handle the situation. You'll want to have the right mfg data -- serial number, UUID, KL, KA, KV, LO -- for things to work correctly. Otherwise quite a few things will be not-quite-right in fun and surprising ways. cheers, m On Mon, Oct 17, 2011 at 1:47 AM, Sridhar Dhanapalan srid...@laptop.org.au wrote: I'm wondering what is the recommended process for changing an XO motherboard.

serial numbers on new motherboards
I'm wondering what is the recommended process for changing an XO motherboard. The hardware side is relatively straightforward. However, new motherboards come with blank serial numbers.

My understanding is that parts of the XO OS first-boot setup and interactions with an XS are derived from the serial number. I can't recommend leaving it blank. It is a required field in the manufacturing data, which is expected to be present and to be unique among XOs. We have devised a method (using an olpc.fth script) to write the serial number of the XO chassis to the mfg-data on the board. What is the method used in other deployments? Good. That should work well. How are you generating/setting the UUID, the secret part of the device authentication ? I too am interested in hearing how other deployments such as Uruguay deal with this problem. Cheers, wad ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
