Modem interrupt assignment and sharing:
--- Bootup diagnositcs for card in PCI slot 00:0d.0 ----
=== Finished modem firmware and bootup diagnostics section. ===
=== Next deducing cogent software ===
===================================
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.

Support type needed or chipset: AmbientTech
Under Linux 2.6.n kernels, the chipset is NOT SUPPORTED . Read
InfoGeneral.txt about alternatives.
Vendor=1813 Ambient Tech was acquired by Intel with its HaM (Host assisted
Modem) chipsets.
There is no support under 2.6.n kernels!!
Intel-v92ham-453.tgz 2.4.n kernels was the FINAL 2.4.n update for HaM modems,
available at:
http://linmodems.technion.ac.il/packages/Intel/ham/
http://developer.intel.com/design/modems/support/drivers.htm
It is NOT functional when compiled under 2.6.n kernels.
But under the 2.4.nn kernels, all HaM chipsets were supported,
with a single EXCEPTION: the odd PCI_ID 1813:4100 modems. For the
explanation, see message:
http://linmodems.org/cgi-bin/ezmlm-cgi?1:mss:9448:200210:fbhcoigfcimgkjdedjad
