There is a Bad IRQ=255 . Carefully read the related guidance in Modem/ModemData.txt The modem will NOT function because of interrupt assignment: IRQ 255 Possible corrections are: 1) to access the the boot up BIOS change to a non-PNP mode. Instructions for accessing BIOS are at: http://linmodems.technion.ac.il/resources.html within: Additional Resourcces. 2) Within some BIOS setups, IRQ assignments can be changed. 3) On non-laptop systems moving the modem card to another slot has helped. 4) Sometimes upgrading the kernel changes IRQ assignment. -----PCI_IDs------- --CompilerVer- Feature List: Primary Subsystem Distr KernelVer kernel default CPU ./scanModem test 1813:4000 16be:0001 debian_version 2.6.15-1-686 4.0.3 4.0.4 i686 Information on several modem chipset providers is provided below, because ambiguities remain on the correct choice of supporting software. == Checking PCI IDs through modem chip suppliers == Vendor=1813 Ambient Tech was acquired by Intel with its HaM (Host assisted Modem) chipsets. Intel-v92ham-453.tgz ifor 2.4.n kernels is FINAL 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 and will NOT be updated to support the 2.6.n kernels, Intel maintainer Dorian Araneda has reported. But under the 2.4.nn kernels, all HaM chipsets are 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 Vendor=8086 is Intel, Inc. producing HaM and 536ep host controller free (HCF) modems, 537 soft modem http://developer.intel.com/design/modems/ .
