Pentnt
Updated: January 21, 2005
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.
