Thanks to everybody for their replies. 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!
