[. . . ] SI-2P+ Dual Socket 604 Server Board User's Manual 4200-0333-02 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 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. User's Manual 3-10 Chapter 3 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. This process normally consumes about 50-60 PCI clocks without PCI delayed transaction. Leave this item to its default [Disabled] setting when using ISA cards that are not PCI 2. 1 compliant. 3. 2. 3. Integrated Peripherals Onboard IDE-1 Controller This item enables or disables the onboard IDE-1 controller. Onboard IDE-2 Controller This item enables or disables the onboard IDE-2 controller. USB Controller This option enables or disables the USB controller. SI-2P+ BIOS Setup 3-11 USB Keyboard Support This item allows you to select [BIOS] for using USB keyboard in DOS environment, or [OS] in OS environment. USB Mouse Support This item allows you to select [BIOS] for using USB mouse in DOS environment, or [OS] in OS environment. Onboard LAN Controller This item enables or disables the onboard LAN controller. Onboard LAN Boot ROM This item allows you to use the boot ROM (instead of a disk drive) to boot-up the system and access the local area network directly. Onboard SCSI Controller This item enables or disables the onboard SCSI controller. Onboard FDD Controller This item enables or disables the onboard FDD controller. Onboard Serial Port 1 This item determines which I/O addresses the onboard Serial Port 1 controller will access. [Auto]: The system automatically select an I/O address for the onboard Serial Port 1. [3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4, 2E8/IRQ3]: Allows you to manually select an I/O address for the onboard Serial Port 1. [Disabled]: Disables the onboard Serial Port 1. Onboard Serial Port 2 This item determines which I/O addresses the onboard Serial Port 2 controller will access. [Auto]: The system automatically select an I/O address for the onboard Serial Port 2. [3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4, 2E8/IRQ3]: Allows you to manually select an I/O address for the onboard Serial Port 2. User's Manual 3-12 Chapter 3 Onboard Parallel Port This item specifies the I/O address used by the parallel port. [Disabled]: This option prevents the parallel port from accessing any system resources. When the value of this option is set to [Disabled], the printer port becomes unavailable. [378]: This option allows the parallel port to use [378] as its I/O port address. The majority of parallel ports on computer systems use IRQ7 and I/O Port 378H as the standard setting. [278]: This option allows the parallel port to use [278] as its I/O port address. [3BC]: This option allows the parallel port to use [3BC] as its I/O port address. Parallel Port Mode This item specifies the parallel port mode. [SPP]: (Standard Parallel Port) Allows bi-directional parallel port operation at normal speed. [EPP]: (Enhanced Parallel Port) Allows bi-directional parallel port operation at maximum speed. [ECP]: (Extended Capabilities Port) Allows bi-directional parallel port operation at a speed faster than the normal mode's data transfer rate. [EPP+ECP]: Using parallel port as EPP & ECP mode. EPP Mode Select This item selects the EPP mode. ECP Mode Use DMA This item selects the DMA channel of the parallel port. PWRON After PWR-Fail This item sets the system action after a power failure. SCR Port Address This item sets the I/O address and IRQ of the onboard SCR (Smart Card Reader) port. SCR Port IRQ After enabling the SCR port, here you can set the IRQ for SCR port. [. . . ] They should know best what your system configuration is and your problem. If you feel that you need to contact ABIT directly you can send email to the ABIT technical support department. First, please contact the support team for the branch office closest to you. They will be more familiar with local conditions and problems and will have better insight as to which resellers offer what products and services. [. . . ]
