Finally I got a firmdl3 version that FULLY works on Winnt, both in slow and
fast mode! No more "write: permission denied" or "read: permission denied"
problems... No more interrupted downloads at all on my system (NTWS 4 SP6a).
Note: I've not tested it on Win95 system.
I had to patch original files from Kekoa Proudfoot to handle the
infamous "permission denied" error on NT. I've also introduced some more
progress indicators during the download.
I think that the patch should work also on *nix systems: it uses few
modification to the sources. I hope that the patch will become part of the
normal distribution of this very good tool for Winnt users too.
Here is the patch. It's for the "multifile" version of firmdl3
(firmdl3.tar.gz). You can untar the file in legos/util to get the sources in
legos/util/firmdl3 dir.
From legos/util you can apply the patch as usual and compile it with make.
Ex.:
$ cd /legos/util
$ tar xvfz firmdl3.tar.gz
$ patch -u -b < firmdl3.3.0-win.diff
$ cd firmdl3
$ make
Here is the diff file (firmdl3.3.0-win.diff):

That's all.
Hope it helps... :-)

| Hello Paolo, Would you mind sharing that binary executable of firmdl3 ??? Maybe Kekoa should make executables available on his site? I tried using NQC -firmware but got "RCX not responding" after what appeared to be a successful download. Thanks, (...) (25 years ago, 18-Jan-00, to lugnet.robotics.rcx.legos)
