I recently installed Ubuntu to dual-boot with Windows XP. I have not
made much use of it yet, because the system has been unable to find
the dial-up modem.
The original modem in the tower is an Agere, and I installed a second
Conextant modem, thinking Ubuntu might be happier with it, but without
result.
I then used Scanmodem (and I include the results below).
Where "possible corrections" are suggested, I have put the first and
third in bold type, as they were the options that first struck me. I
admit that I am a novice at this! My question is whether any changes
to the BIOS, or to IRQ assignments will make Windows XP unhappy.
Any advice will be gratefully received,
Brant

Modem interrupt assignment and sharing:
===================================
The modem interrupt (IRQ) is 255 . IRQs of 0 or 255 are not functional!!
The CPU cannot control the modem until this situation is corrected!!
Possible corrections are:
1) Within the boot up BIOS, change from a Windows to a
non-PNP/Other Operating System type.
Instructions for accessing BIOS are at:
http://linmodems.technion.ac.il/resources.html within:
Additional Resourcces.
2a) Add an option "pci=routeirq" to the kernel boot up line.
Here is an example paragraph from /boot/grub/menu.lst :
title Ubuntu, kernel 2.6.15-26-686
root (hd0,6)
kernel /boot/vmlinuz-2.6.15-26-686 root=/dev/hda7 ro pci=routeirq
initrd /boot/initrd.img-2.6.15-26-686
savedefault
2b) Same as above, but use "pollirq" instead of "pci=routeirq".
3) Within some BIOS setups, IRQ assignments can be changed.
4) On non-laptop systems, moving the modem card to another slot has helped.
5) Sometimes upgrading the kernel changes IRQ assignment.

===== Advanced Linux Sound Architecture (ALSA) diagnostics =====
The ALSA packages provide audio support and also drivers for some modems.
ALSA diagnostics are written during bootup to /proc/asound/ folders.
The ALSA verion is 1.0.16
The modem cards detected by "aplay -l" are: None
The /proc/asound/pcm file reports:
-----------------------
00-02: ALC883 Analog : ALC883 Analog : capture 1
00-01: ALC883 Digital : ALC883 Digital : playback 1
00-00: ALC883 Analog : ALC883 Analog : playback 1 : capture 1
about /proc/asound/cards:
------------------------
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe024000 irq 17
PCI slot 00:10.1 has a High Definition Audio Card
The drivers are in the kernel modules tree at:
/lib/modules/2.6.24-16-generic/ubuntu/sound/alsa-driver/pci/hda/snd-hda-intel.ko

The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.2.3
and the compiler used in kernel assembly: 4.2.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.2
linuc_headers base folder /lib/modules/2.6.24-16-generic/build
However some compilations and executable functions may need additional files,
in the FileNames.h (so called kernel "h"eaders) collection installed
in /usr/include/ .
For martian_modem, additional required packages are needed. The also
required headers of package libc6 are commonly installed by default.
Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev
packages, for kernels 2.6.24 and later versions.
In not included on your install CD, search for them at
http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.
If a driver compilation fails, with message including some lack of
some FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include.
The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev
If an alternate ethernet connection is available,
$ apt-get update
$ apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to
display the needed package list:
Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
$ sudo dpkg -i *.deb
