[. . . ] Because the CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation as shown. Colden Arrow Socket 754 CPU ZIF mPGAB Socket When you put the CPU into the ZIF socket. No force require to insert of the CPU, then press the level to Locate position slightly without any extra force. 2-4 Install Memory This motherboard provides two 184-pin DUAL INLINE MEMORY MODULES (DIMM) sites for memory expansion available from minimum memory size of 64MB to maximum memory size of 2. 0GB DDR SDRAM. Valid Memory Configurations Bank 184-Pin DIMM Bank 0, 1 (DIMM1) DDRDDR266/DDR333/DDR400 DDR SDRAM Module Bank 2, 3 (DIMM2) DDRDDR266/DDR333/DDR400 DDR SDRAM Module Total System Memory (Max. 2. 0GB) PCS X1 X1 2 Total Memory 64MB1. 0GB 64MB1. 0GB 64MB2. 0GB 9 Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer to figure 2-4 to see what a 184-Pin DDR266/DDR333/DDR400 DDR SDRAM module looks like. DIMM1 (BANK0+BANK1) DIMM2 (BANK2+BANK3) Figure 2-4 When you install DIMM module fully into the DIMM socket the eject tab should be locked into the DIMM module very firmly and fit into its indention on both sides. For the DDR SDRAM CLOCK is set at 200MHz, use only DDR400-compliant DDR Modules. When this motherboard operate at 200Mhz, most system will not even boot if non-compliant modules are used because of the strict timing issues, if your SDR Modules are not DDR266-compliant, set the DDR SDRAM clock to 133MHz to ensure system stability. Turn off your power when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards. 2-5-1 Procedure For Expansion Card Installation 1. Read the documentation for your expansion card and make any necessary hardware or software setting for your expansion card such as jumpers. Remove your computer's cover and the bracket plate on the slot you intend to use. Install the necessary software driver for your expansion card. 2-5-2 Assigning IRQs For Expansion Card Some expansion cards need an IRQ to operate. In a standard design, there are 16 IRQs available but most of them are already in use. Standard Interrupt Assignments 10 IRQ 0 1 2 3* 4* 5* 6* 7* 8 9* 10 * 11 * 12 * 13 14 * 15 * Priority N/A N/A N/A 8 9 6 11 7 N/A 10 3 2 4 N/A 5 1 Standard function System Timer Keyboard Controller Programmable Interrupt Communications Port (COM2) Communications Port (COM1) Sound Card (sometimes LPT2) Floppy Disk Controller Printer Port (LPT1) System CMOS/Real Time Clock ACPI Mode when enabled IRQ Holder for PCI Steering IRQ Holder for PCI Steering PS/2 Compatible Mouse Port Numeric Data Processor Primary IDE Channel Secondary IDE Channel * These IRQs are usually available for ISA or PCI devices. 2-5-3 Interrupt Request Table For This Motherboard Interrupt request are shared as shown the table below: INT A Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Onboard LAN Onboard USB 1 Onboard USB 2 Onboard USB 3 Sound INT B INT C INT D INT E INT F INT G INT H IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support "Shared IRQ" or that the cards don't need IRQ assignments. Conflicts will arise between the two PCI groups that will make the system unstable or cards inoperable. 2-5-4 AGP Slot This motherboard provides an AGP Slot, only support the 1. 5V 4X/0. 8V 8X AGP VGA card. It will burn and damage the motherboard due to chipset can not support AGP 2X (3. 3V). Before you plug-in AGP card, please make sure the following notice is fully understood and practiced. If your AGP card has "AGP 4X notch (show below) please make sure your AGP card is AGP 4X/8X (1. 5V/0. 8V) not AGP 2X (3. 3V) 11 2x notch 4x notch AG SLO P T Example 1: Example 2: SiS 305 & ATi Rage 128 Pro AGP card those golden finger is compatible with 2X/4X mode AGP slot, but only can support 2X (3. 3V) only. If you install these cards in Intel® 865 based motherboard it will burn and damage the motherboard. We also find Diamond Vipper V770 golden finger is design for 2X/4X mode AGP Slot. If you install this AGP card in motherboard without change the jumper setting to 4X (1. 5V), it will burn the motherboard. 2-6 Connectors, Headers 2-6-1 Connectors (1) Power Connector (20-pin block) : PWR2 ATX Power Supply connector. This is a new defined 20-pins connector that usually comes with ATX case. The ATX Power Supply allows to use soft power on momentary switch that connect from the front panel switch to 2-pins Power On jumper pole on the motherboard. When the power switch on the back of the ATX power supply turned on, the full power will not come into the system board until the front panel switch is momentarily pressed. [. . . ] Additionally, when a password is enabled, you can also require the BIOS to request a password every time your system is rebooted. You determine when the password is required within the BIOS Features Setup Menu and its Security option. If the Security option is set to "System", the password will be required both at boot and at entry to Setup. If set to "Setup", prompting only occurs when trying to enter Setup. [. . . ]
