PENTNT

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

PENTNT [-c] [-f] [-o] [-? | -h]

none.

-h (NT3.51)

-? (NT3.51)

Displays Help for the command.

-c (NT3.51)

Enables conditional emulation. 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 switch, you must restart the computer for the changes to take effect.

-f (NT3.51)

Enables forced emulation. 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 switch is useful for testing software emulators and for working around floating-point hardware defects known to the operating system. If you select this switch, you must restart the computer for the changes to take effect.

-o (NT3.51)

Disables forced emulation and reenables floating-point hardware if it is present. If you select this switch, you must restart the computer for the changes to take effect.
