Q: Does Pentium or Pentium Pro MB support Deturbo mode?
A: The Deturbo mode was originally designed to slow down CPU speed for old
applications (especially old games). It uses programming loop to wait or
delay special event. This programming method is considered very bad since
the delay of loop highly depends on the CPU speed and the application fails
at high-speed CPU. Almost all new applications (including games) use RTC
or interrupt to wait event. There is no need for Deturbo mode now. The
Turbo switch is now used as Suspend switch. However, some MBs still
support Turbo/Deturbo function via keyboard. You can set the system to
