I have an AOC-LPZCR2 Zero Channel Raid card, which was purchased along with a 6025B-3RB Super Server. When booting the server, I got an "Unknown firmware error": "Error code: C7".
Is this part repairable?
Go into the bios under Advanced Tab - PCI Configuration then Frequency for PCIX#1 slot, please change it from Auto to PCI-X 100MHz, which is the correct speed for this card and that will fix the unknown firmware error.
