MPS Version Ctrl For OS: This item specifies which version of MPS (Multi-Processor Specification) this motherboard will use. OS Select For DRAM > 64MB: This item allows you to access the memory that is over 64MB in OS/2. Leave this item to its default [Non-OS2] setting for operating system other than OS/2. HDD S. M. A. R. T Capability: This Item enables or disables the HDD S. M. A. R. T. Please check your HDD's User's Manual to see if it supports this function.
