Windows flashing instruction for the D-Link DIR-300 to DD-WRT (by Brainslayer, modified by Sash, v24_SP1 specific added by Deepak)

Install RedBoot
configure your local ip to 192.168.20.80 connect your lan cable to the WAN port of the router. plugoff the power cord and replug it. You must press the RESET key for 5 sec. now enter the redboot using telnet and ip 192.168.20.81 and port 9000. connect your lan cable to the dir300 wan port. you might need several tries since its only available for 1 second after aprox. 5 sec. of booting (in the appendix is a windows instruction for easy connecting to redboot) When you succeed you will be rewarded with a RedBoot> prompt. DIR-300 Info: IP: 192.168.20.81/255.255.255.0, Gateway: 0.0.0.0 Default server: 192.168.20.80 now start a local tftp server on your computer and place ap61.ram as well as ap61.rom in the root dir of this server back to the redboot enter: load ap61.ram go now a new temporarily bootloader should start. (on serial console it will display some warning. but you dont need to care about). It will be waiting for connection at the LAN side of the router, so follow the instructions that follow. Plug off your cable from the wan port and reconfigure your local (computer) ip to 192.168.1.2 (set your DHCP server to serve 192.168.1.1 as the only address in the DHCP pool and the TFTP must also be available at 192.168.1.2). Now you should be pluging on to any of the lan ports. Then connect via telnet to 192.168.1.1 (or to the ip your dhcp server served to the redboot) and port 9000. A DD-WRT> prompt should welcome you. IMPORTANT: while doing the following steps. never plugoff the lan cable or the power cord fis init About to initialize [format] FLASH image system - continue (y/n)? y *** Initialize FLASH Image System ...

Program from 0x807f0000-0x80800000 at 0xbffe0000:. reset now the unit will reboot and the new bootloader will be executed and is waiting for your connection. this will take 30+ sec.

Install DD-WRT
The following will work for the initial flash AND a recovery

connect to the bootloader with telnet on port 9000 and ip 192.168.1.1 (If you have installed Micro Redboot read the wiki page about it first)

now do the following (consider that fis create operations are taking sometimes *several* minutes to finish, in my particular case it took more than 5 minutes):

fis init ip_address -h 192.168.1.2 load -r -b 0x80041000 linux.bin fis create linux fconfig boot_script true fconfig boot_script_timeout 4

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

and press enter for every other option to confirm the defaults.

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

You are done now. Wait for your router to reboot. It will take about 1–2 minutes. It may blink and reset once or twice (as noted). Now open a Browser and connect to address 192.168.1.1 you should be able to see the dd-wrt page.

That's All
