1.8 Safety Precautions Warning! Always completely disconnect the power cord from your chassis whenever you work with the hardware. Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the motherboard. Modern electronic devices are very sensitive to static electric charges.
1.9 Jumper Settings This section provides instructions on how to configure your motherboard by setting the jumpers. It also includes the motherboards's default settings and your options for each jumper. 1.9.1 How to set jumpers You can configure your motherboard to match the needs of your application by setting the jumpers. A jumper is a metal bridge that closes an electrical circuit.
EMI problem. The J2 jumper settings control the outcome of what the computer will do in the event the watchdog timer is tripped. Table 1.4: Watchdog timer output (J2) Function Jumper Setting IRQ11 1 1-2 closed * Reset 1 2-3 closed * default setting Note: The interrupt output of the watchdog timer is a low level signal. It will be held low until the watchdog timer is reset. 1.9.4 Riser card selection (J3 & J4) The AIMB-740/741 contains a riser card selection that enables the riser card function.
1.10 System Memory The top-left edge of the AIMB-740/741 contains two sockets for 184-pin dual in-line memory modules (DIMMs). Both two sockets use 2.5 V double-data-rate synchronous DRAMs (DDR SDRAM). DIMMs are available in capacities of 64, 128, 256, 512 MB, or 1 GB. The sockets can be filled in any combination with DIMMs of any size, giving your AIMB740/741 single board computer between 64 MB and 2 GB of memory. Use the following table to calculate the total DRAM memory within your computer: Table 1.
1.12 Cache Memory Since the second-level (L2) cache has been embedded into the Intel® socket 478 Pentium® 4/Celeron™ processor, you do not have to take care of either SRAM chips or SRAM modules. The built-in second-level cache in the processor yields much higher performance than the external cache memories. The cache size in the Intel ® Pentium ® 4 processor is 256/512 KB. In the Celeron CPU, the cache size is 128KB. 1.
