For what it is worth, some computers, specially older ones, had in their
BIOS an option to "set" the operating system to one or more Microsoft
options and also the wonderful "Other systems". This last choice would
overcome problems such as yours.
The option was soemtimes known as PnP on/off.

Hi everyone.
I was trying to set up the 0620 (Pinball-B) here in another machine that
uses the (cr*p) SIS chipset and I got the following problem:
The system Bios keeps trying to set the IRQ of this modem to Low (and
shares it with the on-board audio device).
The result is the following syslog entries:

For now, I decided to disable the on-board audio. That did the trick.
I'll try to set acpi=off pci=routeirq and see what happen.
Unfortunately, I can't manually change the IRQ for PCI devices in my
bios nor deny IRQ sharing.
Just a heads up for you that have this modem.
The described above would happen even when using Windows, I guess.
See you.
