Hello.I got work "se401.o" in redhat 7.1j( linux2.4-4) as below. 1,I run "modprobe -a videodev.o" 2,I run "modprobe -a se401.o" 3,I run "lsmod" and there are "se401 **** * (***) videodev 5024 2 (autoclean)[ se401 bttv]" and I could view the images from webcam. but, rebooting my system and log in root,"se401" disappeared. I ran "lsmod" and showd "videodev 5024 2 (autoclean)[ bttv]" only a bttv module. I want to get se401 module work continually without same setting , after rebooting . anyone has some advises?
