ZL1UMK,
The article you reference also says, "It is important to update the RAID controller firmware before updating the board BIOS". Sounds like you may need to back rev the board BIOS, Update the RAID controller firmware and then update the board.
Has the SRCS16 ever worked for you? Do you have the disk drives connected to the RAID controller? Was there a previous RAID configuration? If so, the parity error may be on the array:
"Possible reasons for parity error are bad cabling or hardware error from a defective drive or an overheated drive. After removing the reason of the data corruption you can carry out parity recalculate to ensure that the parity information of this disk array becomes valid"
