Are you searching for Controller Driver?
I mean P212/256 controller driver
Are you there
I am not getting any reply
Please answer below queries when you are back..
1: Does message "expansion ROM cannot initialize" appear evenafter controller is not connected?
(We need to check whether message is right from controller or not. For that i want you to reboot machine without controller and check status)
2: Are you searching for controller driver?
waiting for your reply
Are you available now
From your reply, i could see that Server identifies the hdds connected.
You know when raid controller is changed, server loses the raid config with it. Now only HDDs contains the raid config. Before attempting reboot using new controller its necessary to import RAID Config from HDD to controller and Raid Array should come online. For that you have to get into Raid Configuration Menu during Server initializing time.
Make sure you have done this and set P212/256 controller as server primary boot controller
