The Jumper S1 (1, 2, and 3) is used to set the Core/Bus (Fraction) ratio of the CPU. The actual core speed of the CPU is the Host Clock Frequency multiplied by the Core/Bus ratio. For example: CPU Clock Core/Bus ratio then CPU core speed If = = = = = 66MHz 3/2 Host Clock x Core/Bus ratio 66MHz x 3/2 100MHz 1 0 0 1 1 0 0 1 1 2 0 1 0 1 0 1 0 1 3 0 0 0 0 1 1 1 1 CPU 1. 5/3. 5 3x 2x 2. 5x 5. 5x 5x 4x 4. 5x AMD K6/K6 2 Intel AMD Cyrix IDT 0 = Open 1 = Short 2-3 CHAPTER 2 HARDWARE INSTALLATION 2. 1-3 CPU Voltage Setting: S2 5 1 S2 V I/O Vcore S2 5 3. 45 3. 5 1 5 3. 45 3. 4 1 5 3. 45 3. 3 1 5 3. 45 3. 2 1 2-4 CHAPTER 2 HARDWARE INSTALLATION V I/O Vcore S2 5 3. 45 3. 1 1 5 3. 45 3. 0 1 5 3. 45 2. 9 1 5 3. 45 2. 8 1 5 3. 45 2. 7 1 5 3. 45 2. 6 1 5 3. 45 2. 5 1 5 3. 45 2. 4 1 2-5 CHAPTER 2 HARDWARE INSTALLATION V I/O Vcore S2 5 3. 45 2. 3 1 5 3. 45 2. 2 1 5 3. 45 2. 1 1 5 3. 45 2. 0 1 2-6 CHAPTER 2 HARDWARE INSTALLATION 2. 1-4 CPU Speed and Voltage Setting: S1 and S2 To set the proper speed and voltage of the CPU, you must know the specifications of your CPU (always ask the vendor for CPU specifications). [. . . ] The DIMM slot has two keys marked "VOLT and DRAM" , so the DIMM memory module can only fit in one direction. Insert the DIMM memory module vertically into the DIMM slot. The plastic clip at the side of the DIMM slot will automatically close. . 2-14 CHAPTER 2 HARDWARE INSTALLATION 2. 2-3 Memory Population Rules 1. This mainboard supports Table Free memory, so memory can be installed in DIMM1, DIMM2, or DIMM 3 in any order. The DRAM addressing and the size supported by the mainboard is shown next page. Using 100MHz CPU Bus frequency, only PC100 DIMM is supported. 2-15 CHAPTER 2 HARDWARE INSTALLATION Table 2. 2-1 EDO DRAM Memory Addressing DRAM Tech. 16M DRAM Density & Width 1Mx16 1Mx16 2Mx8 2Mx8 4Mx4 4Mx4 2Mx32 2Mx32 2Mx32 4Mx16 4Mx16 8Mx8 DRAM Addressing SYMM ASYM ASYM ASYM SYMM ASYM ASYM ASYM ASYM SYMM ASYM ASYM Address Size Row 10 12 11 12 11 12 11 12 13 11 12 12 Column 10 8 10 9 11 10 10 9 8 11 10 11 MB/DIMM Single no.

Avoid rebooting the system when the HDD LED is lit. You can connect the Reset switch from the system case to this pin. (See Figure 2. 1) 2. 3-2 Keylock Keylock allows you to disable the keyboard for security purposes. You can connect the keylock to this pin. (See Figure 2. 1) 2. 3-3 Power LED The Power LED is always lit while the system power is on. You can connect the Power LED from the system case to this pin. (See Figure 2. 1) 2. 3-4 Speaker Speaker from the system case is connected to this pin. (See Figure 2. 1) 2. 3-5 HDD LED HDD LED shows the activity of a hard disk drive. Avoid turning the power off while the HDD led is lit. You can connect the HDD LED from the system case to this pin. (See Figure 2. 1). 2-18 CHAPTER 2 HARDWARE INSTALLATION 2. 4 Floppy Disk Connector: FDC The mainboard also provides a standard floppy disk connector, FDC that supports 360K, 720K, 1. 2M, 1. 44M and 2. 88M floppy disk types. You can attach a floppy disk cable directly to this connector.
