Flash ROM Voltage Selection: JP4 (Yellow color selector)These jumpers set the voltage supplied to the Flash ROM. It depend on Flash ROM Brand. SelectionsJP4 +12V 2-3 (Intel, MXIC) +5V 1-2 (SST, Winbond)
CPU External (Bus) Frequency Selection: FS0, FS1, FS2 (White color Selector) These jumpers sets the clock generator what frequency to send to the CPU, These allow the selection of the CPU’s External frequency (or Bus Clock). The Bus Clock times the Bus Ratio equals the CPU’s Internal frequency (the advertised CPU speed). SelectionsFS0FS1FS2 50M short short short 55M short short open 60M open short short 66M short open short 75M open short open
CPU to Bus Frequency Ratio: BF0, BF1 (Blue color selector) These jumpers set the frequency ratio between the Internal frequency of the CPU and the External frequency (Bus Clock) within the CPU. These must be set together with the bellow jumpers CPU External (Bus) frequency Selection (FS0, FS1, FS2). SelectionsBF0BF1 1.5x 1-2 1-2 2x 2-3 1-2 2.5x 2-3 2-3 3x 1-2 2-3
J-656VXD/J-656VXDP Jumper Setting for CPU
NOTE: À Before install the CPU, Please check the CPU Frequency and Clock Ratio from your supplier. Á For Cyrix 6X86MX series, please double check the CPU’s Frequency and Clock Ratio. Â 75MHz CPU’s Bus Frequency is not in the reqular specification, therefore, we are not recommend to use it. J-656VXDP CPU Voltage Selection (use Q2, Q3 Regulators): JP11, JP12 (Yellow color selector) These jumpers set the Voltage supplied to the CPU. A. CPU Core Voltage (Q2): JP11 SelectionsJP11 2.8V 1-2 3.3V 2-3 3.45V 4-5 3.52V 5-6 B. CPU I/O Voltage (Q3): JP12 SelectionsJP12 3.3V 1-2 3.52V 2-3
CMOS RAM: JP5 (Yellow color selector) This clears the user-entered information stored in the CMOS RAM chip such as hard disk information and passwords. Simply connect a jumper cap over this jumper for a few seconds then remove. But make sure that your computer is turned off. You must enter the BIOS setup (by holding down <DEL> during power-up) after this is done to re-enter BIOS information (see BIOS SETUP) SelectionsJP5 Normal open (Default) Clear CMOS short (momentarily)
System Memory (DRAM) This motherboard supports four 72-pin SIMMs of 4MB, 8MB, 16MB, 32MB, or 64MB to from a memory size between 8MB to 512MB. The DRAM can be either 60ns or 70ns Fast Page Mode or EDO RAM. This mother board also support two 168-pin DIMM Module, it can use only +3V unbuffer synchronous DRAM. Install two memory modules each time as shown in the chart below.
DIMM1: BANK0, DIMM2: BANK1 * We don’t recommand use FAST PAGE/EDO Module with DIMM combination. Central Processing Unit (CPU) The motherboard provides a 321-pins ZIF Socket 7. The CPU on mother board must have a fan attached to prevent overheating.   Что будет с Землей, если ось ее сместится на 6666 км? Что будет с Землей? - задался я вопросом...
