ESXi 5.1 (SOLVED) Not detect 10Gb nic NC-550SFP

Hi.

The problem is:

I've installed ESXi 5.1.0 upd 1 on a DL380 G6 with a NC-550SFP nic adapter. I've used the specific CD for HP ESXi 5.1.

Instead of upgrade, till now I had ESXi 4.x in this server, I've selected a New installation, cleaning the local datastore.

The setup process has finished correctly, but ESX doesn't detects the nic adapter. I've tried to add the corresponding drivers using vMA, but always get the same response: File is skipped. Seems like the ESXi has the same drivers.

When I installed ESXi 4.x, setup procedure ask me for additional cd's drivers,

Do you know what can I do to make this nic adapter visible ?

Thanks

SOLUTION: I flashed the last firmware for this adapter, look at HP site, Support & drivers. Search for NC550SFP (Bios firmware upgrade)
