WAS 6.2 Installation clarifications

Hi

I was trying to install WAS 6.2 on my machiene.

I had a couple of CD's but i cound not find a distinct setup for WAS. What i could find was the distinct setup for SAPJ2EE engine and SDM.

Can you please help me how can i find what is to be installed and how

Th CD's were from the EP5 's installation pack.

Thanks
