[. . . ] SI-2Pa Dual Socket 604 Server Board User's Manual 4200-0327-02 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. [. . . ] The value of the base memory is typically 640K for system with 640K or more memory size installed on the motherboard. Extended Memory This item displays the amount of extended memory detected during system boot-up. Total Memory This item displays the total memory available in the system. Advanced Menu 3. 2. 1. Advanced BIOS Features User's Manual 3-6 Chapter 3 CPU Hyper-Threading This option enables or disables the processor's Hyper-Threading Technology. Leave this item to its default setting to enable the simultaneous multi-threaded (SMT) processor so as to make one physical processor looks like two logical processors to the OS and applications. This option is for CPU with Hyper-Threading Technology only. For more information on "Hyper-Threading Technology", please visit Intel Web site at http://www. intel. com/homepage/land/hyperthreading. htm , http://www. intel. com/design/chipsets/ht/. Quick Power On Self Test When set to [Enabled], this item speeds up the Power On Self Test (POST) after powering on the system. The BIOS shorten or skip some check during the POST. Hard Disk Boot Priority This item selects the hard disks booting priority. By pressing <Enter> key, you can enter its submenu where the hard disks detected can be selected for the booting sequence to boot up system. This item functions only when there is the option of [Hard Disk] in any one of the First/Second/Third Boot Device items. 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] fields 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 NumLock Status This item determines the default state of the numeric keypad at system booting up. [On]: The numeric keypad functions as number keys. [Off]: The numeric keypad functions as arrow keys. Security Option This item determines when the system will prompt for password - every time the system boots or only when enters the BIOS setup. SI-2Pa BIOS Setup [Setup]: The password is required only when accessing the BIOS Setup. [System]: The password is required each time the computer boots up. 3-7 NOTE: Don't forget your password. 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. But by doing this, you will have to reset all previously set options. MPS Version Control For OS This item specifies which version of MPS (Multi-Processor Specification) this server board will use. If you use an older OS for dual processor executing, please set this option to 1. 1. Small Logo(EPA) Show This item determines to show the EPA logo when booting. User's Manual 3-8 Chapter 3 3. 2. 2. Advanced Chipset Features DRAM Timing Control This item controls the DRAM timing. Press <Enter> key to enter its menu. Memory Type This item displays the type of memory module you are using. SI-2Pa BIOS Setup 3-9 Memory Frequency This item displays the frequency of memory module you are using. 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. Active to Precharge Delay This item controls the number of DRAM clocks used for DRAM parameters. DRAM RAS# to CAS# Delay This item controls the latency between the DRAM active command and the read/write command. DRAM RAS# Precharge This item controls the idle clocks after issuing a precharge command to the DRAM. Delayed Transaction When set to [Enabled], the PCI bus will be freed up when the CPU is accessing 8-bit ISA cards. This will allow PCI and ISA buses to be used more efficiently and prevents performance dropping on the PCI bus.
