Can i use Asus Recovery Tool to flash DDWRT? Is it possible?
There have been special instructions in this thread on how to flash dd-wrt to the asus N66U.. There is a KNOWN problem with nvram and you have to use their cd to break into the CFE and clear NVRAM after a flash otherwise you get will get nothing.

If you said A say a B. What tool from the Asus CD should i use to clear NVRAM? Without it thoose "special instructions" is useless.
Actually Tomato doesn't work on the RT-N66U right now - there's an obscure bug in script command argument passing that only affects this router - that has the devs scratching their heads...
Tomato Shibby is working for me (1.28 AIO). Couldn't get DD-WRT to load any other than mini, even after following the instructions.
If it works for you fine, but that mod author is still hunting for this obscure bug!
how do I go about checking the remaining nvram? I'm using an iMac, FYI.
With what firmware? With Asus, you can telnet in, and run:
Code:
nvram show
No idea on DD-WRT or Tomato.
i'm running the stock fw. What do you mean by "telnet in"?
Connect to your router using a telnet client, like Putty. Or if the thought of connecting to a Linux shell scares you, you can also run "nvram show" through this hidden webpage:
Code:
http://192.168.1.1/Main_AdmStatus_Content.asp
(changing the IP for your router's)
EDIT: looks like the output gets truncated due to its size, so you won't get the bit that interests you when using that webpage. Putty it is then.

NVRAM isn't something given. It's the name of the special storage area of the router that survives reboots, and contains the configuration settings.
More nvram means more memory for firmware, and then more functionality inside firmvare?
So why every one waiting for Asus to fix it? I could not be fixed by ddwrt programmers?
No. The NVRAM is *ONLY* for storing configuration settings. The firmware itself resides in another area of the flash memory, and there is still a lot of space left for that. And the RAM used to run the software is also something completely separate.
As explained previously, the NVRAM is set up by the CFE, which is similar to a computer's BIOS (while the firmware would be the operating system, i.e. Windows, Linux, etc...). The source code for this is not available - this is something that is separate from the firmware, and manually tinkering with it has a strong chance of bricking a router beyond recovery.
