How can I get the hardware inventory details of the Sun Servers like T5220 running Solaris 10?

I would like to see the following details:
1. Chassis Information - Part Number, Serial Number etc.
2. Slots Present in the chassis
3. Modules/Cards equipped on the slots. Module details like Part Number and Serial Number.
4. Physical ports and its details.

I have already tried prtconf, prtdiag, iostat but did not help much.

Thanks in Advance!
