Re: How to Disable Ethernet

Hi Paul,

How can I be sure that KITL is no longer accessing it?
When I run my driver, I get interrupts from the 91C96 that
should not be occuring (i.e. the interrupt does not match
the mask). If I add a 10 second delay to the end of my
InterruptHandler, no interrupts occur during that time.
However, immediately upon return from the InterruptHandler
a new interrupt is generated. There must be some other
code that is accessing the 91C96 that I have not properly
turned off.

Thanks for the help! -Jeff
