|  I have a pentium system with a PnP bios.  It runs Win95 on one partition 
|  and I am working on getting FreeBSD on another.  I am having a bit of a 
|  problem with the modem however.  It is a US Robotics Sportser internal 
|  PnP modem.  

I can't say that I've got any great expertise here, but I do have USR
Sportster 28.8 internal modem running under FreeBSD 2.1R.  I don't run
Win95 and have PnP disabled. 

|            In Win95 I managed to get it working (after frobbing my sound 
|  card config).  Win95 reports it as being configured as:
|
|      COM: 3
|      IRQ: 5
|      Address: 110
|      UART: NS 16550AN
|
|  When FreeBSD boots and probes sio2 it comes up with nothing.  Could the 
|  problem lie in the Address?  If so, what would be the appropriate 
|  'port' in the kernel config?  Help?  :)

For what it's worth, my kernel config is:

device		sio0	at isa? port "IO_COM1" tty irq 4 vector siointr
device		sio1	at isa? port "IO_COM2" tty irq 3 vector siointr
# enabled sio2 but changed irq from 5 to 7 to install USR modem:
device		sio2	at isa? port "IO_COM3" tty irq 7 vector siointr
# device		sio3	at isa? port "IO_COM4" tty irq 9 vector siointr

I believe I had to play around a few jumpers (as per the USR manual
for "NOT Using PnP").  I forget why exactly I chose 7, but it works OK
for me.  Sorry I don't have anything to offer re: Win95 and PnP
coexistence.
