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!
