Apparently, you right click in POSE then pick Settings->HostFS options, and you can mount them there (you'll need the HostFS.prc, whereever you get that from), I don't know beyond that because I have no need of itFound some hints on the web that POSE needs a file called HostFS.prc to emulate external SD cards. Not sure how good it works though.
Starting with the m500 model and Palm OS 4.0 most Palm devices actually had SD card slots. Those I've been using certainly have this feature.
I use my m500 with a 1GB SD card.
Wow, nice, thanks.something of interest to you ?
