Ok, I have 2 PC's that are identical. I loaded Redhat9 on the first and Asterisk and installed a x100p card and it works fine. I ghost the first PC and install the ghost on the second PC. Everything comes up on the 2nd PC but I can't get it's x100p card to load. The systems sees the card, it's on interrupt 11. It shows up in /proc/pci and /etc/sysconfig/hwconf and lspci shows it there, but modprobe wcfxo fails (yes modprobe zaptel works). The 2nd PC should be a duplicate of the first [root@defiant sbin]# ./modprobe zaptel [root@defiant sbin]# ./modprobe wcfxo /lib/modules/2.4.20-19.9/misc/wcfxo.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg /lib/modules/2.4.20-19.9/misc/wcfxo.o: insmod /lib/modules/2.4.20-19.9/misc/wcfxo.o failed /lib/modules/2.4.20-19.9/misc/wcfxo.o: insmod wcfxo failed [root@defiant sbin]# Note, the reason for the ghost to the 2nd PC , is that it's CD drive is broken and I don't want to fix it. The reason for 2 identical PC's is that I want one for day to day use and one to test and develop on. Thanks Lee Goodman
