To access the panorama mode in the camera you need to be in P mode.

To set the P mode you need to press the Ok button right arrow to P for Program Auto and press Ok. Then as long as you are using an Olympus xD card you should be able to go to menu and highlight the Panorama option.

It sounds like you set the file settings to a small file size - perhaps in order to get more photos on a single memory card. You need to change the setting to the largest file size possible, at the highest quality. The steps for this will be in your manual. If you need detailed instructions and don't have your manual, let me know and I'll lookup your manual online.
