+Brief F.A.Q
+===========
+
+Q. Zaptel compiled with no errors but when I try to modprobe zaptel I
+receive "FATAL: Error insering zaptel (/lib/modules/2.6.x.x/misc/zaptel.ko):
+Unknown symol in module or unknown parameter (see dmesg)
+
+A. You need to recompile your kernel with CONFIG_CRC_CCITT=y or
+CONFIG_CRC_CCITT=m. To do this, run 'make menuconfig' and change it under 
+'Library Routines -> CRC-CCIT functions'. If you compiled it as a module,
+load it, otherwise reboot.
