I recently setup my first RAID array using a Promise FastTrak100 TX2 PCI add-in card. I'm now looking to setup another array using the onboard Silicon Image RAID controller on my ASUS A7N8X Deluxe motherboard. But when i boot now the SI controller doesn't display during POST so i can't get into the RAID setup utility. I'm hoping this has to do with something simple to fix, maybe just flashing my BIOS? In order to do that i need to know what PCB revision i have and not sure where/how to find that out....any help on topic would be much appreciated.
