by I have a solution to the problem reported on the serial I/O ports
for my Iwill P55XB2 motherboard under freeBSD 2.2.2.
This was filed as problem report internal identification `i386/4315'.
I purchased an SIIG multi I/O Dual IDE/2-serial/1-parallel/1-game port card
for about $70.
I disabled the serial ports on the Iwill motherboard and enabled them
on the I/O card and voila the 16550A UART function came right up.
The SIIG is rated at 115.2Kbps so it should be fast enough.
I purchased the Iwill P55XB2 motherboard primarily because it has
five (5) PCI slots and three (3) ISA slots, non shared.
Another piece of email came in that may be of interest:

There is a BIOS update (dated 08/26/97) at
http://ftp.iwill.com.tw/p55xb2dl.htm . However, I don't know if it can
solve the problem.

} With FreeBSD 2.2.2...
} During the bootup probe (and from 'dmesg'), I get:
}
} sio0 not found at 0x3f8
} sio1 not found at 0x2f8
}
} and no serial port activity works, e.g. tip hw (with /dev/cuaa0).
}
} The BIOS shows this hardware to be present at the appropriate
} addresses and IRQs (both at BIOS config and during startup).
} But Freebsd 2.2.2 cannot successfully probe it.
