I'm not sure what you have done wrong. It could be the copy of APEX
you downloaded. I suggest you reflash a known good image (i.e. your
backup), and then flash the new version of APEX with the script listed
at the end of this email. I have tested it quite thoroughly, and have
submitted it to the APEX maintainer for inclusion in the next version
of apex-nslu2 in Debian. If is based on the flash-kernel script that
Debian currently uses. To use it, copy the version of APEX you want to
flash to /boot/apex.flash and then run the script. APEX will be
written to the NSLU2 flash while preserving any customizations to the
APEX configuration.
