nslu2 default firmware & fstab

1. I reflashed to orginal firmware with ethernet cable direct from PC to slug
2. I changed my subnet mask on the router to 255.255.0.0 and connected the slug to it - this made it visible on its default IP address
3. I changed its IP address so it would be in the same range as my LAN, and then changed the subnet mask back on my router.  I set admin password on the slug
4. I set up fstab 

//192.168.0.77/FLASH_2_1_1 /home/matt/test_mount cifs username=admin,password=secret_password,uid=matt,gid=matt,rw 0 0

Result : I can mount my slug!
