BIOS Setup
If you use non-specification settings for normal operation, your system may not be stable, and
may affect system reliability. Also, we do not guarantee the stability and compatibility for
settings that are not within specification, and any damage of any elements on the motherboard
or peripherals, is not our responsibility.

After choosing the "CPU Operating Speed" option as "User Define", you can choose the
external clock frequency from 100MHz to 250 MHz. The best frequency is either 100MHz or
133MHz depending on the CPU type and its speed. The default setting is 100MHz.

setting is wrong, the system will hold.
