MECCommander.cpp
|

|
|
|

|
|
Abstract:
|
||
|
|
|
||
|
|
This dll prevents the MEC Commander install program from successfully
|
||
|
|
calling the cpuid.exe. This is because the cpuid.exe can AV's with a
|
||
|
|
divide by 0.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.

We do not want to run this application since it AV's with a divide by zero
|
||
|
|
calculation. The only purpose for this exe is to time the CPU. Since the
|
||
|
|
final result of this calculation is a string in a dialog box we can safely
|
||
|
|
bypass this. The app puts a string "Pentinum 166 or Better recommented" in
|
||
|
|
the cases where it cannot get the CPU frequency. The interesting thing
|
||
|
|
here is that the app will actually run better with this patch since this
|
||
|
|
cpuid exe also faults on 9x.
