[. . . ] 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. 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. User's Manual 3-10 Chapter 3 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. 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 LAN1 Controller This item enables or disables the onboard LAN1 controller. SI-2Pa BIOS Setup 3-11 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 LAN2 Controller This item enables or disables the onboard LAN2 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 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/COM1, 2F8/COM2, 3E8/COM3, 2E8/COM4]: 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/COM1, 2F8/COM2, 3E8/COM3, 2E8/COM4]: Allows you to manually select an I/O address for the onboard Serial Port 2. [Disabled]: Disables the onboard Serial Port 2. 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. User's Manual 3-12 Chapter 3 [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. [. . . ] 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. [. . . ]
