I'm using an Intel 486DX2-66 VLB motherboard, a VLB I/O card for my first 
serial port, and a Zoltrix V.FC internal modem.  I grabbed the 
2.0-RELEASE/newer floppies (the ones dated Dec 5 around 1:00am), and 
installation went fine - almost.

Upon reboot, the serial port which is my modem was not recognized, but the 
other one was.

Yes, I verified IRQ's of every piece of hardware on the machine (I had been 
running ver 1.0 in the past on the same hardware, different motherboard).  
Yes, of course I disabled the second serial port on the VLB card, and ensured 
mo interrupt conflicts.  Yes, I switched slots - several times.  Yes, I tried 
swapping I/O port numbers of the modem and the other card's serial port.

Yes, upon bootup, the hardware base address is recognized by the BIOS, and 
yes, it runs comm software fine if I boot from a DOS floppy with comm stuff on 
it.

Everything I did worked just fine *except* the modem was never recognized by 
the bootup initialization procedure of FreeBSD (and thus, this sio device was 
never available to experiment with).

(1) Is anyone else having this problem ?
(2) Does anyone know *why* this is happening ?  (ie. 16550's not 
always recognized ?)
(3) Does anyone have a fix ?
