I purchased the cool animal just a week ago, and my wife and I really love it. After finding Mock's excellent site and others, I've started investigating the software structure for hacking possibilities.

Now my questions: Though all sites I've visited say Rio Receiver uses an NFS root volume on the server, my copy doesn't look like that. Rather it appears to use a RAM file whose entire contents come from "receiver.arf" file (there's no "mercury.arf"). Below is the file's untar'ed list:

drwxr-xr-x root/root 0 2002-09-02 07:58:20 ./

Can anybody verify this?

Thanks,

It uses an NFS server. In the stock Windows server software, the files are packed into the .arf file, rather than being a separate directory tree (Windows can't do device files for one).

Thanks. No wonder the arf file is a plain tarball rather than a compressed one and I cannot change its name for sharing violation. (Does "arf" stand for "audio receiver file"?)

Then I tried "mount -t nfs -o ro peko:/tftpboot/x.x.x.x /mnt/tmp" from my Linux box where peko is the Win2K server and x.x.x.x is either my Rio's IP address or Linux' own (I did SSDP to register ir), but connections were refused. Do they use a special port number or is some other authentication needed? Also, if /tmp is on a read-only NFS volume, wouldn't some applications suffer inability to use /tmp? Or, is /tmp just another mounting point?

Yes. "Some applications" would. The player isn't one of them.
