Chapter 3 Onboard Resource Settings NOTE: Table below shows only some of the possible memory configurations. Warning! The 256MB DIMMs represented above are REGISTERED memory chips. DO NOT use registered and non-registered memory chips simulta- neously! (Check with your memory dealer for more information). Cache Memory Penitum II processors have the L2 (Level 2) cache built into their architecture, so there is no need for an L2 cache on the motherboard. -
Page 37: Frequently Asked Questions
Frequently Asked Questions Q: Why don’t I get a display after I put in my old DIMM module? A: The 440BX chipset requires the memory manufacturer to program an EEPROM chip with SPD (Serial Presence Detection) on the module in order for the BIOS to program the 440BX’s timing registers properly. - Page 38 Chapter 3 Onboard Resource Settings Q: Does my operating system support AGP? A: Currently, only Windows 98 and Windows NT 5.0 will have built-in support for AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver from Intel. Please check with your graphics vendor for more details. Q: Will my motherboard run a PII/Celeron/Mendicino CPU? A:Yes, the BIOS version 1.07 supports Celeron 266-300MHz and the BIOS version 1.12 supports the Celeron-A (Mendocino) 300-333MHz.

Page 78: Appendix 2 - Glossary
Appendix 2 Glossary Glossary ACPI (Advanced Configuration and Power Interface) is a power management specification that allows the operating system to control the amount of power distributed to the computer’s devices. Devices not in use can be turned off, reducing unnecessary power expenditure. AGP (Accelerated Graphics Port) is a PCI-based interface which was designed specifically for demands of 3D graphics applications. - Page 79 supply and cooling fan. The keyboard, mouse, serial, USB, and parallel ports are built in. Bandwidth refers to carrying capacity. The greater the bandwidth, the more data the bus, phone line, or other electrical path, can carry. Greater bandwidth, then, also results in greater speed. A BBS (Bulletin Board System) is a computer system with a number of modems hooked up to it which acts as a center for users to post messages and access information.
- Page 80 Appendix 2 Glossary In this case, up to 512MB of the main memory onboard is capable of being cached. However, only 512KB of this memory will be in the cache at any given moment. Any main memory above 512MB could never be cached. Closed and open jumpers Jumpers and jumper pins are active when they are On or Closed, and inactive when they are Off or Open.

TYAN’s BIOS updates can be found at http://www.tyan.com/html/drivers.html ESCD (Extended System Configuration Data) is a format for storing informa- tion about Plug and Play devices in the system BIOS.
- Page 82 Appendix 2 Glossary details for you. ISA stands for Industry Standard Architecture. ISA is a slower 8- or 16-bit BUS (data pathway). Latency is the amount of time that one part of a system spends waiting for another part to catch up. This is most common when the system sends data out to a peripheral device, and is waiting for the peripheral to send some data back (peripherals tend to be slower than onboard system components).
- Page 83 PM timers (Power Management timers) are software timers that count down the number of seconds or minutes until the system times out and enters sleep, suspend, or doze mode. PnP is an acronym for Plug and Play, a design standard that has become ascendant in the industry.
