I have problem using my internal modem on COM1:.

I am running FreeBSD 2.1 on IBM Aptiva. The machine came with a MWave 
card which has a sound-card, fax/modem, DSP and joy stick controller 
(all in one card). Under Win95, MWave is recognized as COM1: IRQ 4, I/O 03F8
(0x3f8). There are two other serial ports A and B being shown as COM2 
(IRQ 3, I/O 0x2f8) and COM3 (IRQ 4, I/O 0x3e8).

I tried several configurations of my kernel for sio0. If I hard code the 
address or "IO_COM1" - the sio0 will not be configured. I tried turning 
off serial ports A & B in BIOS to avoid conflicts, and commented sio1, 
sio2 in the kernel config with no results.
 
BIOS does not have any choice of changing settings on MWave Card. The only 
options are Installed or [Not].

The specs for sio1, sio2 work fine by themselves. However, they go to COM2 
and COM3. So, I have not been able to use the built-in V.34 modem on COM1: 

Any ideas ?

Please help.
