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. [. . . ] 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. Delay IDE Initial This item is used to support some old models or special types of hard disks or CD-ROMs. They may need a longer amount of time to initialize and prepare for activation. Since the BIOS may not detect those kinds of devices during system booting. The ranges are from minimum 0 to maximum 15. SI-1Ns BIOS Setup 3-7 Small Logo(EPA) Show This item determines to show the EPA logo when booting. User's Manual 3-8 Chapter 3 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 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. SI-1Ns BIOS Setup 3-9 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. CPU Clock Ratio This item selects the multiplier factors for your CPU if it is not locked. User's Manual 3-10 Chapter 3 3. 4. Integrated Peripherals Onboard IDE-1 Controller This item enables or disables the onboard IDE-1 controller. Init Display First This item selects to initialize Onboard VGA or PCI Slot first when the system boots. [Onboard VGA]: When the system boots, it will first initialize Onboard VGA. [PCI Slot]: When the system boots, it will first initialize PCI. USB Controller This option enables or disables the USB controller. USB 2. 0 Controller This option enables or disables the USB 2. 0 controller. USB Keyboard Support This item allows you to select [BIOS] for using USB keyboard in DOS environment, or [OS] in OS environment. SI-1Ns BIOS Setup 3-11 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. Onboard LAN Boot ROM When set to [Enabled], this item allows the system to boot from network by the onboard LAN1 controller boot ROM. Onboard LAN2 Controller This item enables or disables the onboard LAN2 controller. Onboard LAN Boot ROM When set to [Enabled], this item allows the system to boot from network by the onboard LAN2 controller boot ROM. 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. [Disabled]: Disables the onboard Serial Port 2. Onboard Parallel Port This item specifies the I/O address used by the parallel 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. [. . . ]
