[. . . ] WI-1P Intel Pentium 4 Workstation Board Socket 478 User's Manual 4200-0391-01 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. [. . . ] [Yes]: The system automatically detect the unused DIMM and PCI slots, and stop sending clock signal to these unused PCI slots. [No]: The system always send clock signal to all 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. User's Manual 3-12 Chapter 3 3. 4. 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. DRAM RAS# Precharge: This item controls the idle clocks after issuing a precharge command to the DRAM. WI-1P BIOS Setup Video BIOS Cacheable: 3-13 As with caching the system BIOS, enabling the Video BIOS cache will allow access to video BIOS addressed at C0000H to C7FFFH to be cached, if the cache controller is also enabled. The larger the range of the Cache RAM, the faster the video performance will be. Memory Hole At 15M-16M: When set to [Enabled], the memory address space at 15M-16M will be reserved for ISA expansion cards that specifically requires this setting. This makes the memory from 15MB and up unavailable to the system. Delay Prior to Thermal: This item selects the delay time before thermal activation. AGP Aperture Size: This option specifies the amount of system memory that can be used by the AGP device. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Init Display First: This item selects to initialize AGP or PCI Slot first when the system boots. [AGP]: When the system boots, it will first initialize AGP. [PCI Slot]: When the system boots, it will first initialize PCI. DRAM Data Integrity Mode: This item selects the type of DRAM in your system. ECC is "Error Checking and Correction". Choose the ECC option only when your memory is ECC type.
