Topic created on: July 16, 2006 16:56 CDT by morphique .

I am trying to debug a device driver using SoftIce. But I can't set breakpoints on functions in .sys file. Everytime I set the breakpoint on function the program keeps breaking in ntoskrnl. Any idea on what might be going wrong?
I am also looking for info on how to locate sytem service dispatch table so that I may find out function corresponding to the ID passed on to the INT2e/SYSENTER function.

Cheers

Found the way of locating SSDT through KeServiceTable() export of ntoskrnl.
