[. . . ] You may change the parameter settings to improve system performance. However, it may cause your system to be unstable if the setting is not correct for your system configuration. Advanced Chipset features > DRAM Timing Selectable Available options: By SPD: System will define timing according to default of Dram. (Default) Manual: Allow user to define timing himself. Advanced Chipset features > CAS Latency Time When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM timing. Available options: 2, 2. 5 Advanced Chipset features > Active to Precharge Delay Select the operating system that is active to precharge delay. Available options: 5, 6, 7 Advanced Chipset features > DRAM RAS# to CAS# Delay This field lets user to insert a timing delay between the CAS and RAS strobe signals, used when RAM is written to, read from, or refreshed. Fast gives fater performance; and Slow give more stable performance. This field applies only when synchronous DRAM is installed in the system. Available options: 2, 3 47 Advanced Chipset features > DRAM RAS# Precharge If an insufficient number of cycles are allowed for the RAS to accumulate its charge before DRAM refresh, the refresh may be incomplete and the DRAM may fail to retain data. Fast give faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system. Available options: 2, 3 Advanced Chipset features > MGM Core Frequency This item allows user to determine the frequency of CPU FSB / Memory / GFX Core Clock (Low) / GFX Core Clock (High). Available options: 400/266/133/200 MHZ 400/200/100/200 MHZ 400/200/100/133 MHZ 400/266/133/267 MHZ 400/333/166/250 MHZ Auto Advanced Chipset features > System BIOS cacheable Allow the system BIOS to be cached to allow faster system performance. Available options: Disabled, Enabled Advanced Chipset features > Video BIOS cacheable Allow the video BIOS to be cached to allow faster video performance. Available options: Disabled, Enabled Advanced Chipset features > AGP Aperture Size (MB) This item allows you to determine the effective size of the AGP Graphic Aperture. Available options: 4, 8, 16, 32, 64, 128, 256 Advanced Chipset features > Intruder Detection This item allow user to detect the housing is opened or not. It works only when the housing is designed with CASE OPEN cable and connected to motherboard. Available options: Disabled, Enabled Advanced Chipset features > Delayed PWROK Signal This item is used to add the compatibility between motherboard and power supply for avoiding booting up failed. Available options: 400ms (default) / 300ms / 200ms /100ms / Disabled Advanced Chipset features > On-Chip VGA This item allows user to control the on-chip VGA. Available options: Disable, Enable Advanced Chipset features > Frame Buffer Size This item allows user to control the on-chip frame buffer size. Available options: 1M, 4M, 8M, 16M, 32M 48 Integrated Peripherals This submenu appears if you select the option "Integrated Peripherals" from the main menu. This option allows you to configure the I/O features. Integrated peripherals > OnChip IDE Device This parameter allows you to "Enable" or "Disable" the IDE device connected to the primary or secondary IDE connector. Integrated peripherals > Onboard Device This item allows you to set onboard devices. 49 USB Controller: This item lets you enable or disable the USB controller. [. . . ] All you have to do is just click on the "GO", and no more steps afterward, of all listed drivers, grey checks indicate necessary drivers; you cannot click them off. Red checks can be disabled if you don't want to install them now. Press the icon will prompt the "Install Driver" page. You may also press "Back" to return to the Main page. Once clicking "GO", EzInstall will run the installing procedure automatically, and prompt a reboot dialog (Some drivers or utilities may skip the reboot part). 63 6. 2 Installing Utilities Installing Utilities is virtually the same as installing drivers. AOpen provides you many friendly and powerful utilities to manage your system. [. . . ]
