MS-6728 ATX Mainboard Hyper Threading Function This field is used to enable or disable the Hyper Threading function. Setting to [Enabled] will increase the system performance. Settings: [Enabled], [Disabled]. MSI Reminds You... Enabling the functionality of Hyper-Threading Technology for your com- puter system requires ALL of the following platform Components: *CPU: An Intel® Pentium® 4 Processor with HT Technology; *Chipset: An Intel® Chipset that supports HT Technology; *BIOS: A BIOS that supports HT Technology and has it enabled; *OS: An operating system that supports HT Technology. For more information on Hyper-threading Technology, go to: www.intel.com/info/hyperthreading MPS Revision This field allows you to select which MPS (Multi-Processor Specification) version to be used for the operating system. You need to select the MPS version supported by your operating system. Settings: [1.4] and [1.1]. APIC ACPI SCI IRQ This field allows you to specify which IRQ is used for ACPI SCI. Option Description Enabled Use one IRQ from IRQ 20~23. Disabled Use one IRQ from IRQ 09~11. CPU L1 & L2 Cache Cache memory is additional memory that is much faster than conventional DRAM (system memory). When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU. The setting controls the internal cache (also known as L1 or level 1 cache). Setting to [WriteBack] will speed up the system performance. System BIOS Cacheable Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. Setting options: [Enabled], [Disabled].
