2. SDRAM Clock Selector: U2 #4
This selector can choose SDRAM clock Synchronous or Asynchronous to CPU Bus frequency. When
choose Asynchronous can let users have more choice of NON-PC100 SDRAM at over 66 MHz Bus
frequency .
U2 #4 ON SDRAM clock same as AGP clock (66MHz) Asynchronous.
U2 #4 OFF SDRAM clock same as CPU Bus clock (66MHz,75MHz,100MHz,
103MHz,112MHz): Synchronous.
3. CMOS RAM: JBAT1 (Yellow color selector)
WARNING: Make sure your computer is POWER OFF when you are CLEAR CMOS.
Connect a jumper Cap over this jumper for a few seconds, will clears information stored in
the CMOS RAM Chip that input by user, such as hard disk information and passwords.
After CLEAR CMOS, you must enter the BIOS setup (by holding down <DEL> during
power-up) to re-enter BIOS information (see BIOS SETUP).
