Bug report update:

Boot: /kernel -c
config> flags sio0 0x80
config> flags sio1 0x80

[continue booting, on probe...]
sio0: probe test 5 failed
sio0: probe test 8 failed
sio0 not found at 0x3f8
sio1: probe test 5 failed
sio1: probe test 8 failed
sio1 not found at 0x2f8


Can anyone help explain the probe test failures or
point me to some documentation on probe tests?
Is there any way to get even more diagnostics?

Thank you.

O/S:		FreeBSD 2.2.2

Original Post:


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.

I have a recently-purchased Iwill P55XB2 motherboard
with Award Modular BIOS v4.51PG.

All extraneous cards have been pulled and the ports work
perfectly under MS-DOS 6.22.

There are no internal serial-like cards (i.e. a modem).

Anyone have any ideas?
