How do I know if I have ATI card too, and activate it

I have a Thinkpad T400 model (6474-B84), which contains a video card Mobile Intel (r) GMA 4500MHD with 1 GB of RAM. It takes a powerful card, but his performances in Second Life are incredibly bad and weak.

I did a Google search and I realized that T400 really two cards video: one integrated (Intel) and an additional a (ATI) and I should be able to switch between them, either in the BIOS, depending on the operating system on the fly. I have Windows XP Pro, so I had to use the method of the BIOS.

Then I entered the BIOS and I changed the discreet graphics card instead only in-house, but when I started WinXP and looked at the display options, I always had the card Intel GMA... why? How will I know if I have the cards? And how to move on the more powerful ATI card? It is a must to use metaverses. Thank you in advance.

There are T400 who has only card intel integrated, there are others who have the dual graphics card.
