- The 386 uses a 2x clock, while the 486 uses a 1x clock. However, there are
- chip sets used in 486 machines that like to have a 2x clock as input, they
- put out a 1x clock to the 486 though. Maybe they hope to make the CPU clock
- input more stable that way, I don't know. There are 486 motherboards that
- let you select if you want to run with a 2x or 1x oscillator. Sorry, can't
- remember the manufacturer now.
