I have a similar problem in that when booting to FreeBSD from Win95, 
FreeBSD will usually not recognize the parallel port.  The only way I've 
found that's guaranteed to get the port recognized is not to start Win95 
(but the DOS-mode does start) after FreeBSD succesfully recognizes the 
port.  Then it will also recognize it the next time FBSD boots.

And one other way, listed below.

What also always works is if, when rebooting to FBSD, I enter into the 
bios setup and exit (don't have to do anything, but this may depend on 
the manufacturer).

I really don't know if you have a similar problem, but the basic problem 
with not recognizing the parallel port sounded so similar I thought it'd 
be worth mentioning since the above work-around is somewhat easier.

Also, please format your message in the form of 60-70 columns per row.  
Maybe nix the tabs, too.

Outnumbered?  Maybe.  Outspoken?  Never!
