First things first before your rusty brain can corrupt all your data:
Remove the hard disk from the bays
Use a paper clip to activate at the back of the device
Login using admin, password is blank.
Enable network settings
Add corresponding shares
If you are using boot from usb, remove the usb disk to default to telnet without user
pwconv passwd usermod -s /ffp/bin/sh root pwck grpck login store-passwd.sh reboot
Now rejoice and dust the old memory regularly.
