CPU Frequency and Host Bus Frequency
The following table shows the jumper settings for the CPU frequency and its corresponding host bus
frequency. IN denotes the jumper is installed on both pins.

CPU Voltage
The 200 MHz CPU uses a clock voltage of 3.3 volts, and the 266 MHz and 300 MHz CPU use a clock
voltage of 2.5 volts.
WARNING Double-check voltage jumper settings before starting the system! Setting a high voltage for a
266 MHz or 300 MHz processor will destroy the processor.
The following table shows voltage jumper settings. IN denotes the jumper is installed on both pins.

BIOS Password Clear
J16 on the system board (near the parallel port) enables or disables the BIOS password stored in
CMOS RAM. By default, the jumper is not installed, and the password (if present) is enabled. If the
jumper is installed, the password is cleared, allowing the AMIBIOS Setup program to be accessed
without entering a password. You may need to remove the PCI option boards (if installed) to access
J16.
