By not customized, I mean that the file will be the GENERIC kernel config 
file.  This doesn't seem to be the correct way as I get this error message:

config: /usr/src/sys/i386/conf/GENERIC:279: devices with zero units are not 
likely to be correct

What file do I add this line to?:

device sio0 at isa? port IO_COM1 flags 0x10 irq 4
