Depends on the BIOS ... but usualy, EmbeddedPCs canīt be up
and running that fast. Linux itself can be downsized to operate
within a few seconds. The AXIS-Web/ModemCam based on uClinux (m68knommu),
for example, is fully operational within 5 seconds after
supplying power.

mount the root-filesystem read-only and create a (umsdos)-partition
for the data (reiserfs isnīt an option, as it usualy needs
30MB for the journal)
