This allows clear reference to the products as just a processor. This is the model used in past packaging tech- nologies like PGA, TCP, PQFP, DIP, etc.
  • Page 10 Typically, 3D graphics rendering requires a tremendous amount of memory, and demands ever increasing throughput speed as well. As 3D products for the personal computer become more and more popular, these demands will only increase. This will cause a rise in costs for both end users and manufacturers.
  • Page 11 EP-6VBA The EP-6VBA is designed with ATX form factor - the new industry standard of chassis. ATX form factor is essentially a Baby-AT baseboard rotated 90 degrees within the chassis enclosure and a new mounting configuration for the power supply. With these changes the processor is relocated away from the expansion slots, allowing them all to hold full length add-in cards.
  • Page 12 Introduction The EP-6VBA is equipped with an I/O back panel. Please use the appropriate I/ O shield (figure 3). PS/2 Mouse USB port PS/2 KEYBOARD Figure 3: I/O back panel layout The EP-6VBA has a single 20-pin connector for ATX power supplies. For ATX power supplies that support the Remote On/Off feature, this should be connected to the systems front panel for system Power On/Off button.

  • Page 20 Installation The EP-6VBA supports (3) 168-pin DIMMs (Dual In-line Memory Module). The DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized DRAM). • DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or 125MHz (8ns) bus speed. • If you use both 50ns and 60ns memory you must configure your BIOS to read 60ns.
  • Page 21 EP-6VBA Figure 3 displays the notch marks and what they should look like on your DIMM memory module. DIMMs have 168-pins and two notches that will match with the onboard DIMM socket. DIMM modules are installed by placing the chip firmly into the socket at a 90 degree angle and pressing straight down (figure 4) until it fits tightly into the DIMM socket (figure 5).

    EP-6VBA Award’s ROM BIOS provides a built-in Setup program which allows user to modify the basic system configuration and hardware parameters. The modified data will be stored in a battery-backed CMOS, so that data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM will stay unchanged unless there is a configuration change in the system, such as hard drive replacement or a device is added.
