BIOS Setup Boot To OS/2 for DRAM > 64MB This allows you to run the OS/2® operating system with DRAM larger than 64MB. When you choose No, you cannot run the OS/2® operating system with DRAM larger than 64MB. But it is possible if you choose Yes. 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 computer 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; and *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. To find out which version to use, consult the vendor of your operating system. Settings: 1.4, 1.1. 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) and external cache (also known as L2 or level 2 cache). Setting options: Disabled, WriteBack, WriteThru. WriteBack & WriteThru refer to the cache's write policy, which determines how it handles writes to memory locations that are currently being held in cache. The WriteBack cache policy will produce the best performance. 3-11
