you seem to have an IRQ assignment issue. This is a Linux problem unrelated
to the HSF driver.

You can try these options.

1) Try playing with the following kernel boot parameters:

"pci=noacpi", "acpi=off", "noapic" and/or "apm=off".

2) Configure and install a generic 2.4 kernel (from kernel.org) with the
ACPI patches found on this web site:


3) Configure and install a generic 2.6 kernel from ftp.kernel.org.

With option 2 and 3, you need to install the generic modem driver package
(instead of a package specific to a single distribution/kernel). You will
find the generic drivers under the title "Generic packages with source" on
the download page. I recommend using the RPM when your distribution supports

Subject: [hsflinux] Conexant Modem drivers not loading

I am running Mandrake 9.2 on a Sony Vaio PCG-NV105 laptop, and just can not
get the modem working. I have downloaded the appropriate HSF modem driver,
unzipped and installed with the RPMDRAKE. Every time I try and do anything
with it, HSFCONFIG for example, it tells me that the drivers are not
loaded. I have run dmesg, and it tells me  "PCI : No IRQ known for interupt
pin B of device 0:1f. 6. Please try using pci=biosirq"   I have checked
that device 0:1f is indeed the modem, but I have already added the line
append="pci=biosirq" into my lilo.conf file, as I have found instructions
to do elsewhere. Am I right to have done this ? and if so, why am I still
getting these messages in dmesg ? Any help would be appreciated as I am
looking to use this as my main business machine instead of Windows, but can
not do so until I have a functioning Modem.

Many Thanks,
