Network Storage Adapter
"EPFS202UA020" and "FS202WU-1B0" is silkscreened on the board.
- A date code of 0517 (April 2005) is also on the board.
This device would seem to be a Cellvision FS-202U
- (the FS-202WU [wireless capable] probably shared the same board).
This device is listed on the linux-mips ADM5120 device list.
In the absense of a DHCP server, the device will assume the IP of 192.168.0.101.

Recovery via ADM Boot
Hit the spacebar three times quickly after power-on - you can then transfer
- a desired file to flash via XMODEM (Tera Term will work fine if you're
- in [or have] a Windows environment to work with). [1] [2] [3]
A successful recovery should look something like the following..
