Subject:   help - BSD not recognizing serial ports

I am a newkid when it comes to BSD. I am installing BSD 2.2 on a second partition.
I am able to boot and login as root or any other of the user names which have been
set up. The problem is that my configuration does not recognize the serial ports.
I am convinced that this is a controller problem. I have searched the FAQs without
finding anything relevent to my particular problem.

the output of "dmesg | grep sio" is
  sio0 not found at 0x3f8
  sio1 not found at 0x2f8
  sio2 disabled, not probed
  sio3 disabled, not probed

The GENERIC config file is set too
  device   sio0  at isa? port "IO_COM1" tty irq 4 vector siointr
  device   sio1  at isa? port "IO_COM2" tty irq 3 vector siointr
  device   sio2  at isa? port "IO_COM3" tty irq 5 vector siointr
  device   sio3  at isa? port "IO_COM4" tty irq 9 vector siointr

I have a Amptron PM9200 i430TX mainboard. The following excerpts are from the mainboard doc
    onboard super multi-I/O chip supports 2-serial ports with 16550 fast UART 
    compatable ...
  and
     Two High Speed Serial Ports (16550 UART Compatible)
This is all I could find out about the serial controller. I have a request in for more 
documentation to Amptron, but I have not heard anything yet.
 
I have used the W95 partition to verify that com1 and com2 are at 0x3f8 and 
0x2f8. As for the IRQ, I have no clue. This is the only documentation I could 
find which seemed relevent.

I have checked the serial port configuration against several people with BSD
installed and we appear to have the same entries. Furthmore the FAQ provided
me with the default serial settings, and it appears that I have the default settings.

The question is what am I missing. I am at wits end. I believe the controller on
the mainboard is either not recognized, or requires special settings. Is it
possible to use this configuration? If not I would really appreciate info on the best
way to proceed(probably purchasing and configuring a controller card). I would prefer to 
make the current configuration work if possible.

Thanks for any assistance.
