The link above indicates that it is not a good idea to format an SD card
to ext3, and by implication, to other formats commonly used by Linux.
I'd like to see a suggestion as to how to make a bootable SD card with
a small Linux--perhaps Damn Small Linux, or ?
Wondering if it's possible to run a Linux version on one of those little
7 inch "computers" that come with M/S CE5 Windows systems. (I don't
know what cpu is in them.)
