How do you install both the Primary and the Secondary CA cert?

Someone using Verisign has handed us both a primary and secondary CA cert to install. Aka:

Primary EV SSL Intermediate CA Certificate

and

Secondary EV SSL Intermediate CA Certificate

I forget how this is done. Do I just connect the two in the same file? Eg. like this?
