SubjectDevice driver installation.

Hello,
I have started to learn device driver writing. I studied the character
device driver 'zero device' described by Michael Johnson in his
"Writing Linux Device Drivers" and coded it.
But after I compile as given by him, I see that the driver is not
inserted. I did 'insmod'. Then too the device is not inserted.
When I did 'lsmod' I see that the device is inserted.
But the device file is not to be found in /dev directory. Also, when I
do an 'open' from an application program I fail.

Please help me out.

regards
Satheesh
