Hi James,

I didn't get your e-mail yesterday! Thanks for resending! That was most

To clarify...yes, I used olpc-update not fs-update. I'd like to chase the
root of this idiosyncrasy however I'm also in the midst of user testing for
Squeakland (Etoys) and my priority is getting Etoys 4.1 tested with the
latest build Sugar build.

The whole purpose of my query is to write a step-by-step guide for another
organization (Education Kindling) team in the Philippines because they have
incoming laptops that need to be ready for deployment, in hopefully two
weeks. It's not a big pilot. Just 100 XO 1.5s. I just noticed the firmware
oddity when I was reading through the directions online and checking my
firmware build.

Thank you for pointing out the Receiver set-up! I glanced at the headings
quickly and didn't read it carefully. Thank you! I have no way of going
through the steps of NandBlasting (though I've done so with the XO 1.0) as I
only have one 1.5, but I will include the steps as it looks like it's
already been tested.

Also, please let me know if there's a quick set-up guide in a handy dandy
pdf/word doc already available out there. I certainly don't want to reinvent
the wheel.

I am expecting another week of Etoys test and then I'll go ahead and try to
reproduce the oddity that I observed.

Thank you for your time!!!
