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. ===================================== PCIbus=00:0d.0 00:0d.0 Communication controller: Ambient Technologies Inc HaM controllerless modem (rev 02) Flags: medium devsel, IRQ 255 Memory at ef005000 (32-bit, non-prefetchable) [size=4K] I/O ports at e400 [size=256] Capabilities: [60] Power Management version 2 For candidate modem in PCI bus: 00:0d.0 Class 0780: 1813:4000 Communication controller: Ambient Technologies Inc HaM controllerless modem Primary PCI_id 1813:4000 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 ====== end AmbientTech section ======= Completed candidate modem analyses.
