Unfortunately no. I was being a poorly educated consumer when I bought the chassis. I wasn't aware I needed one so I didn't buy it along with the server. I bought this third party after checking for reported compatibility (confirmed via driver inclusion and mention of specific model in man page).
I think I've tried that combination of pci1000,60.1000.1021 but can't say for sure so I'll give it another try. Attempting Sol 10 update 7 right now. (confirmed hardware combination setup is working via a Vista and ESXi installs) -- This message posted from opensolaris.org
