Ok, more weirdness.
ntrw stopped working. I tried it about 10 times, and it would always spend a few minutes writing, and then would give me a "parameter is incorrect." And Audrey still gave me the Invalid IFS thing. Same error happens no matter what .cf i use, even my own backups that had previously worked.
Eventually I tried copying the infinity .cf to the CF card via the audrey's shell this way:
fs-cifs -a //Computer:18.104.22.168:/aud /aud guest guest
to mount the dir with the .cf images
allows audrey to recognize flash card insertion
cat newimage.cf > /dev/cf
I rebooted with datebook button, and it told me "Loading from CompactFlash" and booted. Woohoo. Except that it isn't InfinitySpecial, it's my current version. However, the screen is all flashy and slow, so I know it's running from RAM. So I try to re-flash the audrey by rebooting with Power and Datebook. It goes through the motions like it's doing it BUT: It still boots my current version into RAM. When I regular-reboot, it's still my current version (though not in RAM).
OK, I think, maybe i'm a dumb#### and i accidently used "mkcf" on one of my own backups, instead of infinity's verions. So i start from scratch: "mkcf" Infinity's file, and use "ntrw" (which now works, no parameter error) to put the newspecial.cf on my card.
Datebook-reboot with card: still current verion
Datebook-power-reboot with card: still current version
