[. . . ] This item functions only when there is the option of [Hard Disk] in any one of the First/Second/Third Boot Device items. BIOS Setup Quick Power On Self Test When set to [Enabled], this item speeds up the Power On Self Test (POST) after powering on the system. First Boot Device / Second Boot Device / Third Boot Device / Boot Other Device Select the drive to boot first, second and third in the [First Boot Device], [Second Boot Device], and [Third Boot Device] items respectively. The BIOS will boot the operating system according to the sequence of the drive selected. Set [Boot Other Device] to [Enabled] if you wish to boot from another device other than these three items. Boot Up Floppy Seek When set to [Enabled], the BIOS will check whether the floppy disk drive is installed or not. Boot Up NumLock Status This item determines the default state of the numeric keypad at system booting up. Security Option This item determines when the system will prompt for password - every time the system boots or only when enters the BIOS setup. NF-95 3-5 [Setup]: The password is required only when accessing the BIOS Setup. If you forget the password, you will have to open the computer case and clear all information in the CMOS before you can start up the system. Delay For HDD (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. 3-6 NF-95 3. 3 Advanced Chipset Features Onboard GPU This item enables the onboard GPU function. Frame Buffer Size This item specifies the Onboard VGA share memory size. K8<->NB HT Speed This item sets the speed of HyperTransport between CPU and Northbridge. NB-->SB HT Speed This item sets the speed of HyperTransport from Northbridge to Southbridge. NB<--SB HT Speed This item sets the speed of HyperTransport from Southbridge to Northbridge. K8<->NB HT Width This item sets the HyperTransport width between CPU and Northbridge NB<->SB HT Width This item sets the HyperTransport width between Northbridge and Southbridge. BIOS Setup NF-95 3-7 DRAM Configuration Click <Enter> key to enter its submenu: 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. DRAM Clock This item controls the number of DRAM clocks used for the DRAM parameters. CAS Latency Time This item controls the latency between the DRAM read command and the time that the data becomes actually available. Min RAS# Active Time This item specifies the minimum RAS# active time. RAS# to CAS# Delay This item controls the latency between the DRAM active command and the read/write command. RAS# Precharge Time This item controls the idle clocks after issuing a precharge command to the DRAM. [. . . ] (You can find it on the screen during the POST sequence. ) · · 5-2 NF-95 · CPU: Type in the brand name and the speed (MHz) of your CPU. (Illustrate the over-clocking status if you had done so. ) Example: Intel 650 3. 4GHz (OC FSB=220MHz) Memory brand: Type in the brand and model name of your memory module. Example: Memory brand: Kingston (KVR533D2N4/1G) Memory size: Type in the size of your memory module. Example: 512M* 4PCS Memory configuration: Type in the memory configuration in BIOS setting.
