I'll give it my analysis, but I'd follow maineiac's advice. Personally, I got the full Copy of Voyager from this forum, set it up and used it to copy the files to my CF, but it depends on how the image was made. If the image size is 16128 kb (in Windows), then ftp or Voyager will most likely work. There are posts available that explain it. I have backed up my Audrey via FTP so it should work. To back it (which I would do prior to flashing your Audrey) up I use:
put /dev/fs0 audrey_backup.cf
This will copy /dev/fs0p0 /dev/fs0p1 and /dev/fsp02 all to one file. Most of the CF images that are posted for download are only /dev/fs0p0 and /dev/0p1 which are all that are needed. The /dev/fsp02 has something to do with your initialization and is not needed when adding a new flash and is probably safer not to mess with.
To backup only /dev/fs0p0 and /dev/fs0p1, I usually map a drive using fs-cifs to my window's or Linux Samba share:
cat /dev/fs0p0 /dev/fs0p1 > /mnt/audrey_backup.cf
cat /dev/fs0p2 > /mnt/audrey_backup.ipl
Ok, now for the ftp CF update:
I haven't tried it this way, but...
1. Setup your FTP server
2. Power on your Audrey
3. Open two "Root" Terminals (prompt should show # not $)
4. Put the CF card in
5. In one terminal type: devb-cf (To initialize the CF card, this will tie up this terminal session)
6. switch to the other terminal.
7. FTP to your server and sign in
get /path/NewCFName.cf CF
(double check the "to" file name, I think it is capital case not lower, I may be wrong)
9. You should see a whole bunch of hash marks (#) for about 2 - 3 minutes then get your prompt back
10. Remove your CF card before powering off!
11. I'll stress that you should always test your image before flashing it to Audrey. To test the image:
a. With Audrey powered off for at least 60 seconds, put your CF Card in
b. While holding down the Date/Time Calendar button only (top right button, do not hold down power) plug in Audrey.
c. Your Audrey should see a message about Reading CF or Flashing from CF.
d. Audrey should boot up, much slower than usual and the screen will flicker some. This will be your current flash not the one you copied to the CF card. If the screen goes blank and is unresponsive, then your CF copy does not have a good copy on it.
