Creating batch file to start mongrel server

Hi all!

I have a database set up to run only on an external hard drive. I am
trying to create a batch file to automatically start the mongrel server
and then open a local host url. On the external hard drive, I have one
folder with Ruby installed and one folder for the project. I need to
create the .bat file to read what drive the external hard drive is on
and then go to the Ruby directory to start the server, then go to the
project directory to open the web page.

Any ideas?

Thanks!

Rhonda
