My disklabel fu is weak and I'm a bit lazy to go RTFS to give you the
100% accurate answer, but my understanding is that: disklabel is in
the netbsd partition, and to find the netbsd partition (and thus the
label) you need it in the mbr partition table.  Are you sure you 720
CF doesn't have netbsd partition in the mbr table?

_d is debug build, _r is release build.  cvs carries release builds.
Debug build is compiled with debugging enabled, which is only useful
for development.  Debug build also enables code to dump various
registers, which is generally useful, and I will probably make that
functionality available in the release builds.

BTW, I have committed the new hpcboot binaries for both wince 2.11 and
wince 2.0, so cvs now has known-working versions.

Well, if the partition is not there, you have no right answer to give
back to ther kernel when it asks ;)


Thanks.
