the driver/function that caused the problem. Always note this address
|
as well as the link date of the driver/image that contains this address.
|
Arguments:
|
Arg1: c0000420, The exception code that was not handled
|
Arg2: f780a9b9, The address that the exception occurred at
|
Arg3: f77f9ab4, Exception Record Address
|
Arg4: f77f9748, Context Record Address
