reset

now the unit will reboot and the new bootloader will be executed and is waiting for your connection.
please reconfigure your local ethernet adapter to 192.168.1.23 since the bootloader is now reachable at 192.168.1.1

connect to the bootloader with telnet on port 9000 and ip 192.168.1.1

now do the following: (consider that fis create operations are taking sometimes several minutes to finish)
load -r -b 0x80041000 linux.bin 
fis create linux

fconfig boot_script true
fconfig boot_script_timeout 3

now type fconfig again and configure the bootscript to
fis load -l linux
exec

now type reset again. the unit should now boot dd-wrt and work as known from other atheros based platforms
