Hi,

Please don't top-post.

If you set anything but full speed mode, do you see different pwm values ?

Also, please provide the output of

	sudo isadump -y 0x295 0x296 0
	sudo isadump -y 0x295 0x296 8
	sudo isadump -y 0x295 0x296 9
	sudo isadump -y 0x295 0x296 10
	sudo isadump -y 0x295 0x296 11

Thanks,
Guenter
