Pentnt

Detects floating point division error (if present) in the Pentium chip, disables floating point hardware, and turns on floating point emulation.

Syntax

pentnt [-c] [-f] [-o]

Parameters

-c   : Enables conditional emulation.

-f   : Enables forced emulation.

-o   : Disables forced emulation and reenables floating-point hardware if it is present.

/? : Displays help at the command prompt.

Remarks

  • Parameters used with this command must be prefixed with - (hyphen) rather than / (slash).

  • Using the -c command-line option

    Floating-point emulation is forced on only if the system detects the Pentium processor floating-point division error at start time. If you select this parameter, you must restart the computer for the changes to take effect.

  • Using the -f command-line option Floating-point hardware is disabled and floating-point emulation is always forced on, regardless of whether the system exhibits the Pentium processor floating-point division error. This parameter is useful for testing software emulators and for working around floating-point hardware defects known to the operating system. If you select this parameter, you must restart the computer for the changes to take effect.

  • Using the -o command-line option If you select this parameter, you must restart the computer for the changes to take effect.
