I get two different kinds of error messages now

. If I type in a random word with modprobe I get the standard, "Module _____ not found." If I type in modprobe snd-sb16 I get "FATAL: Error inserting snd_sb16 (/lib/modules/2.6.9/kernel/sound/isa/sb/snd-sb16.ko): No such device" ????? Thanks everyone.
