Per the txt file for install Since Linksys (or the firmware vendor which might be gemtek or cybertan) disabled the networking within the redboot bootloader (and also the partition management), we have to replace it as first step to get it working. this is only possible with serial console right now

setup your local lan network to and run a local tftp server (see provided tftp server for windows) then enter the following line into the redboot with serial console (baudrate 9600)

ip_address -l -h

this will enable network access now do

load -r -b 0x80041000 redboot_ap65.ram

a new redboot will now start now do the following commands:

fis init 
load -r -b 0x80080000 redboot_ap65.rom
fis create -l 0x10000 -e 0xbfc00000 RedBoot

the new bootloader starts now now do

fis init
load -r -b 0x80041000 linux.bin
fis create linux

and config the bootscript with fconfig
the script must be
fis load -l linux

save the config and type "reset" again to boot up the system to enter the redboot console with this new bootloader you must push the reset button. this will also allow to enter the tftp recovery mode which allows to send a dd-wrt webflash file with tftp to the bootloader for flashing.
