AS ALWAYS, I AM NOT A DEVELOPER, JUST POSTING THE THREAD BECAUSE SOMETIMES ITS HARD TO FIND ALL THE INFORMATION TO COMPLETE YOUR PROCESS...
WITHOUT FURTHER DELAYS... READ BELOW TO ROOT YOUR A100 TABLET
***Make sure you have a File Explorer and Terminal Emulator installed on your tablet***
THIS TUTORIAL TAKES AWAY THE NEED FOR A PC. IT IS MADE TO RUN DIRECTLY ON YOUR TABLET!!! 
As some of my other posts... EASY AS 1-2-3... jejeje
1.) Download the attached file and extract it to your
/sdcard/ (Ensure you place these files on /sdcard/ and not /external_sd/) Do this with your FILE MANAGER
2.) Open your Terminal Emulator and type the following command:
sh /mnt/sdcard/su.sh
***This will take less than 30 seconds to run***
3.) Install the included SuperUser.apk (or you can install your preferred apk) and you are done!!!
Thats it my friends... Hope this helps ease the process... jejeje
