IPC TopNote G serial ports not working
Blaz Zupan
Green797). Most of the hardware works fine, including PCCard, sound and
graphics. I'm having trouble with the serial ports. I have tried 4.4-RELEASE,
but then upgraded to 5.0-CURRENT, thinking that the ACPI support might help.
If I put the sio0 line in /boot/device.hints, dmesg displays this:
sio0: configured irq 4 not in bitmap of probed irqs 0
sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 8250
If I remove the sio line from device.hints, sio does not even appear in the
dmesg output. The laptop has a Phoenix BIOS and offers Win95/98, Win2000 and
Other as options for the "PnP" setting in the BIOS. I set it to "Other",
because that makes the sound and USB support work, but tried the other two
settings without success.
I searched the internet and found a mail from someone having the same problem
installing Linux on such a laptop. My search for a BIOS upgrade was
unfortunately unsuccessfull. Of course, the serial port works just fine under
Windows ME.
Any idea how I might get that damn serial port going? pnpinfo just displays
this:

Two things to try;
1) does your BIOS have a setting to disable serial ports? If so, make sure that sio0 is
enabled in bios.
2) Use that "other os" to find out what resurces it thinks your serial port are using. It
might use something other than irq 4 and port 0x3f7-0x3ff. If so change to correct
resources in the boot configuration (visual editor).
Hope this helps.--

Note that this means that interrupts are not working for this port.

Make sure you haven't disabled the serial port in the BIOS, or configured
it for IR or something. The most "correct" setting would be Win2000, but
as you've noticed, our PCI support doesn't handle this yet. 8(

pnpinfo is only relevant for ISA PnP devices; basically just old sound
cards, and not at all useful here.

You might try to get an ACPI dump via other means, but it looks like this
may be part of the problem. 8(

It is.

It's set to the correct values, I forgot to mention all this in my mail.

Exactly, because it's probably not even activated.

There are three settings for the serial ports: disabled, enabled and auto.
"disabled" is obvious, "enabled" allows me to set the I/O address and IRQ,
which are set correctly, auto probably does that automatically. None of the
settings make the ports work.

Aren't some serial ports configured as ISA PnP devices? Yeah, probably not in
newer machines (especially those supporting ACPI).

I feared that. What are the "other means" to get an ACPI dump? I believe there
is also a FreeBSD ACPI mailing list somewhere.
