The netgear SC101 is a two drive IDE/PATA SAN system. It is not usable as network share through FTP, SMB/CIFS or NFS, but needs a Windows installed driver to make it appear as local drive. It uses a proprietary SAN over IP technology from Zetera called ZSAN. No drivers for Linux or any other than Windows exists. The Windows drivers are quite nice and run on Vista. It can reach about 6.5MB/s.
The device supports RAID-1 but even though 2 drives are in the same box, the mirroring is done over the network, so drains the performance further. Another slightly disappointing feature is it uses its own file system. You cannot take out the drive, and use it in another housing and read the data.
Off topic, I like the comparable Ximeta NDAS technology better: Linux support, choice of file system and better performance, but I would probably like OpenWRT even more, if it can fit in the meager 2MB/8MB.

There is a 3 second bootwait, and the tftp command exists in the bootloader. Dhcp is disabled by default due to BOOTCFG=m:f:"vxWorks" environment variable. Manually changing BOOTCFG=a:nf:"vxWorks" forces dhcp starts right after minimal boot completed and auto-setup IPA and IPA_GATEWAY variables according to network settings. By using tftp it is possible to store files on flash or load ELF(?)executable directly to RAM and run it.
Boot with default settings:

The SC101 has only 1 button.
Note: This will void your warranty!
- Opening this device is quite simple.

My 3.3V phone USB serial cable had its Tx floating pulled up to 3.3V, and if I connected before powerup to pin 10 Rx, the device would not power up. I had to apply power first, then quickly connect pin 10, just in time to press Esc in the 3 second boot wait. If I was too slow, I had to wait a minute for the full VxWorks boot, and type reboot. Upon reboot, the already connected Rx did not matter.
→ port.jtag general information about the JTAG port, JTAG cable, etc.
Not known atm.
- as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!
Source comes from oldwiki → http://wiki.openwrt.org/oldwiki/openwrtdocs/hardware/netgear/sc101 All not completely ported over to the new wiki, mainly did this to add thoughts and resources to this device, also added information/images on version 1.
