- I can change the AT bus speed by changing the clock division factor in
- the setup program. My motherboard is 33MHz, so I could run the bus
- at 16.5 = 33/2. This is probably too fast for some boards, though.
- Other factors are 2.5, 3, and 4. Maybe 5 and 6 too. This is for
- setting the bus to 8MHz (what it supposed to be), for any motherboard
- speed. I.e., 16/2, 20/2.5, 25/3, 33/4, 40/5, and 50/6 are all about 8.
