ruby(1.9.2) and rails 2.3.18 setup with mysql on window 7

Environment : ruby 1.9.2 , rails 2.3.18 and windows 7 with 64 bit 

For mysql:
Step1: install mysql using mysql installer
Step 2 : http://dev.mysql.com/downloads/connector/c/
Step 3: Download mysql-connector-c-noinstall-6.0.2-win32.zip
Step 4: Decided to extract it to the root of my disk, so I ended with a folder named mysql-connector-c-noinstall-6.0.2-win32 in there.
Step 5:

gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-noinstall-6.0.2-win32

Step 6: Copy libmysql.dll from  connector folder which we just extracted to C:\Ruby192\bin>

Ruby on Rails Questions ?

1.What is the difference between bundle and bundle update?

Ans :
bundle is the same as bundle install, which does the following:

• Check if a Gemfile.lock exists. If it does, install all gems with the exact versions specified there.
• If the lock doesn't exist, install gems as specified in the Gemfile, using the latest available / allowable versions according to the Gemfile. Then create the Gemfile.lock to record what versions have been installed.

bundle update on the other hand, deletes / ignores your Gemfile.lock and goes straight to step two.
