[. . . ] Report No FDD For OS: When set to [Enabled], this item allows you to run some older operating system without floppy disk drive. Delay IDE Initial (Secs): This item allows the BIOS to support some old or special IDE devices by prolonging this delay time. A larger value will give more delay time to the device for which to initialize and to prepare for activation. Intel OnScreen Branding: This item determines whether to display the "Intel Inside" logo or not at system boots up. Advanced Chipset Features DRAM Clock/Drive Control: Click <Enter> key to enter its submenu: Current FSB Frequency: This item will show you the current system front side bus speed. Current DRAM Frequency: This item will show you the current DRAM bus speed. DRAM Timing Selectable: Four options are available: Manual By SPD Turbo Ultra. When set to "By SPD", the BIOS will read the DRAM module SPD data and automatically set to the values stored in it. If you set to "Manual", the following five items will be available to let you make adjustments. DRAM CAS Latency: The options are: [1. 5], [2. 0], [2. 5], and [3. 0]. User's Manual 3-10 Chapter 3 Bank Interleave: The options are: [Disabled], [2 Way], and [4 Way]. RAS# Precharge Time: The options are [2T], [3T], [4T], and [5T]. RAS# Active Time: The options are [6T], [7T], [8T], and [9T]. RAS# to CAS# Delay The options are [2T], [3T], [4T], and [5T]. DRAM Command Rate: Two options are available: 2T Command or 1T Command. When the host (northbridge) locates the desired memory address, it then processes the wait state of commands. Set it to 2T Command for system compatibility or to 1T Command for system performance. DRAM Burst Length DDR SDRAM modules provide a Burst mode that means an auto precharge function for programmable READ or WRITE burst lengths of 4 or 8 locations. This means that if we set burst length to 8, the address bus will acesss 8 bytes each cycle to precharge, etc. Write Recovery Time: Two options are available: 2T or 3T. This is the period between two write times. tWTR for DDR400 ONLY: Two options are available: 1T or 2T. This is the Internal WRITE to READ command delay time period.
