[. . . ] R MEZ Socket 370 AGP Motherboard USER'S MANUAL USER'S NOTICE No part of this manual, including the products and software described in it, may be reproduced, transmitted, transcribed, stored in a retrieval system, or translated into any language in any form or by any means, except documentation kept by the purchaser for backup purposes, without the express written permission of ASUSTeK COMPUTER INC. ASUS PROVIDES THIS MANUAL "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT SHALL ASUS, ITS DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS BE LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES (INCLUDING DAMAGES FOR LOSS OF PROFITS, LOSS OF BUSINESS, LOSS OF USE OR DATA, INTERRUPTION OF BUSINESS AND THE LIKE), EVEN IF ASUS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES ARISING FROM ANY DEFECT OR ERROR IN THIS MANUAL OR PRODUCT. Product warranty or service will not be extended if: (1) the product is repaired, modified or altered, unless such repair, modification of alteration is authorized in writing by ASUS; or (2) the serial number of the product is defaced or missing. [. . . ] Typematic Rate (Chars/Sec) (6) This field controls the speed at which the system registers repeated keystrokes. Options range from 6 to 30 characters per second. Setup default setting is 6; other settings are 8, 10, 12, 15, 20, 24, and 30. Typematic Delay (Msec) (250) This field sets the time interval for displaying the first and second characters. Four delay rate options are available: 250, 500, 750, and 1000. Security Option (System) When you specify a Supervisor Password and/or User Password (explained later in this section), the Security Option field determines when the system prompts for the password. The default setting is System, where the system prompts for the User Password every time you start your system. The other option is Setup, where the system goes through its startup routine unless the Setup utility is called, when the system prompts for the Supervisor Password. ASUS MEZ User's Manual IV. BIOS SETUP Chipset Features Setup The "Chipset Features Setup" option controls the configuration of the board's chipset. NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of Chipset Features Setup SDRAM Configuration (By SPD) This sets the optimal timings of settings for items 2­5, depending on the memory modules that you are using. Default setting is By SPD, which configures items 2­5 by reading the contents in the SPD (Serial Presence Detect) device. This 8-pin serial EEPROM device stores critical parameter information about the module, such as memory type, size, speed, voltage interface, and module banks. SDRAM CAS Latency This controls the latency between SDRAM read command and the time that the data actually becomes available. SDRAM RAS to CAS Delay This controls the latency between SDRAM active command and the read/write command. SDRAM RAS Precharge Time This controls the idle clocks after issuing a precharge command to SDRAM. DRAM Idle Timer This controls the idle clocks before closing an opened SDRAM page. SDRAM MA Wait State (Normal) This controls the leadoff clocks for CPU read cycles. Snoop Ahead (Enabled) Enabled will allow PCI streaming. Host Bus Fast Data Ready (Disabled) Leave on default setting. BIOS SETUP 16-bit I/O Recovery Time (1 BUSCLK) / 8-bit I/O Recovery Time (1 BUSCLK) Timing for 16-bit and 8-bit ISA cards, respectively. Graphics Aperture Size (64MB) Memory-mapped, graphics data structures can reside in a Graphics Aperture. Video Memory Cache Mode (UC) USWC (uncacheable, speculative write combining) is a new cache technology for the video memory of the processor. It can greatly improve the display speed by caching the display data. [. . . ] Each LPT port is configured to use a different IRQ and address assignment. MMX A set of 57 new instructions based on a technique called Single Instruction, Multiple Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX instructions are designed to accelerate multimedia and communications applications, such as 3D video, 3D sound, video conference. APPENDIX Glossary 102 ASUS MEZ User's Manual APPENDIX PCI Bus (Peripheral Component Interconnect Local Bus) PCI bus is a specification that defines a 32-bit data bus interface. [. . . ]
