When you are installing Windows 95 or Windows 98 on a computer that has a CPU that runs at 2.2 gigahertz (GHz) or faster, you may receive the following error message:
While initializing device NDIS: Windows protection error
The timing calibration code in the Network Driver Interface Specification (NDIS) driver causes a divide by zero if the CPU runs at 2.2 GHz or faster. This problem does not occur with CPUs that run at 2.1 GHz or slower.
Microsoft has no plans to make an update available for this problem because Windows 95 and Windows 98 are in the "non-supported" phase of the product lifecycle. Additional information about product lifecycles is available at the following Microsoft Web site:
