The following procedure will clear out the NVRAM and set dd-wrt back to default values: With the unit powered on, press and hold the reset button on back of unit for 30 seconds Without releasing the reset button, unplug the unit and hold reset for another 30 seconds Plug the unit back in still holding the reset button a final 30 seconds This procedure should be done before and after every firmware upgrade/downgrade. The firmware writes information to the Nvram . A hard reset clears that information. If you don't clear it properly, parts of the old information be present with the new firmware, which can make it not operate properly.

My C drive was seriously fragmented with about 20% free space. So I ran the built-in Windows disk defrag utility. To my surprise it doesn't work at all! I tried to defragment multiple times and every time it comes back without doing much work. Then I realized that perhaps it didn't know how to get the job done and needed some help. Here's the list of things I did to help the defragmentor out: Relocate the paging file to a different drive and reboot. If the paging file ( pagefile.sys ) is seriously fragmented, it can't be defragmented, and in turn it blocks other files from being defragmented. If you only have one drive (C:), try to make it smaller or eliminate it entirely for...

MinGW is "Minimalist GNU for Windows" - a collection of freely available and freely distributable Windows specific header files and import libraries that allows you to build Windows native executables with GCC. MSYS is a minimal system that provides a POSIX compatible shell and utilities so that you can run the normal set of GNU build tools (such as configure, make). You can download MinGW and MSYS from sourceforge.net: http://sourceforge.net/project/showfiles.php?group_id=2435 . The set of files is overwhelming and installation is confusing sometimes. But here's what I did in order to build ffmpeg on Windows XP: Download "Automated MinGW Installer" (MinGW 5.1.4) Install MinGW 5.1.4. Select "Candidate". Check g++, but leave other options unchecked Finish installation of MinGW Install MSYS DTK 1.0 in C:\msys\1.0. Download "MSYS...
