MS-7021 ATX Mainboard CPU Clock Frequency Selection through BIOS The hardware configuration for CPU clock frequency of the motherboard is set to 100MHz by default. Therefore, to make a 133MHz CPU run at 133MHz when it is installed on the board, you have to adjust the CPU clock frequency in the BIOS setup utility. To set the clock frequency for the installed CPU, refer to Frequency/ Voltage Control in Chapter 3. BIOS Setup.
