I will plan to get firmware from seagate and flash all the drives. I'm downloading knoppix to use seagate's utility...or will it work under fbsd? (It's a moot point since I have a amd64 build without 32bit abi compat.) Is it possible to flash the onboard adaptec "card"? I haven't found any info on how to do that if it is. Sucks to be me! Mike
