[. . . ] BD7III Socket 478 System Board User's Manual 4200-0393-01 Rev. 1. 00 Copyright and Warranty Notice The information in this document is subject to change without notice and does not represent a commitment on part of the vendor, who assumes no liability or responsibility for any errors that may appear in this manual. No warranty or representation, either expressed or implied, is made with respect to the quality, accuracy or fitness for any particular part of this document. In no event shall the manufacturer be liable for direct, indirect, special, incidental or consequential damages arising from any defect or error in this manual or product. [. . . ] First Boot Device / Second Boot Device / Third Boot Device / Boot Other Device: Select the drive to boot first, second and third in the [First Boot Device], [Second Boot Device], and [Third Boot Device] items respectively. The BIOS will boot the operating system according to the sequence of the drive selected. Set [Boot Other Device] to [Enabled] if you wish to boot from another device other than these three items. Boot Up Floppy Seek: When set to [Enabled], the BIOS will check whether the floppy disk drive is installed or not. Boot Up NumLock Status: This item determines the default state of the numeric keypad at system booting up. Disable Unused PCI Clock: This option disables the clock of PCI slot that is not in use. User's Manual 3-6 Chapter 3 [Yes]: The system automatically detect the unused DIMM and PCI slots, and stop sending clock signal to these unused PCI slots. NOTE: Set this option to [No] setting if there are adapters that cannot be automatically detected by the system and will cause malfunction. Security Option: This item determines when the system will prompt for password - every time the system boots or only when enters the BIOS setup. If you forget the password, you will have to open the computer case and clear all information in the CMOS before you can start up the system. MPS Version Ctrl For OS: This item specifies which version of MPS (Multi-Processor Specification) this motherboard will use. OS Select For DRAM > 64MB: This item allows you to access the memory that is over 64MB in OS/2. Leave this item to its default [Non-OS2] setting for operating system other than OS/2. Report No FDD For OS: When set to [Yes], this item allows you to run some older operating system without floppy disk drive. Delay IDE Initial (Secs): This item allows the BIOS to support some old or special IDE devices by prolonging this delay time. A larger value will give more delay time to the device for which to initialize and to prepare for activation. BD7III BIOS Setup 3-7 3-3. Advanced Chipset Features DRAM Timing Selectable: This item sets the optimal timings for the following four items, depending on the memory module you are using. The default setting "By SPD" configures these four items by reading the contents in the SPD (Serial Presence Detect) device. The EEPROM on the memory module stores critical parameter information about the module, such as memory type, size, speed, voltage interface, and module banks. CAS Latency Time: This item controls the latency between the DRAM read command and the time that the data becomes actually available. Act to Precharge Delay: This item controls the number of DRAM clocks used for the DRAM parameters. DRAM RAS# to CAS# Delay This item controls the latency between the DRAM active command and the read/write command.
