Display Serial Number

Hello, I am running Solaris 9 and I need to display the serial number of my machine. How can I do this?

Here is my machine info:
SunOS birch 5.9 Generic_118558-09 sun4u sparc SUNW,Sun-Fire-V240

Thank you,

David

the ser# can not be displayed via command... only if the number was entered with sneep or in the sun explorer default file...

Thank you...

If you can access ALOM over network, 'showplatform -v' will give you serial number, I believe.

Did not work for me....

sc> showplatform -v
SUNW,Sun-Fire-v240

and it won't work at all....
