To upgrade a CPU: 2-6 Hardware Installation 2.6 Configuring the System Memory The system memory is expandable to 512 MB by adding single in-line memory modules (SIMMs). The four 72-pin SIMM sockets accommodate DRAMs, 4-, 16- and 64-MB single-density SIMMs, and 8- and 32-MB double-density SIMMs. These SIMM sockets also accept both FPM and EDO type with or without parity. The EDO feature extends the data transfer cycle, thus improves memory performance. All SIMMs support a DRAM speed of 60/70 ns or less. The SIMMs with parity supports the ECC (Error Checking and Correction) feature that enables the system to detect and correct data errors. To fully support this function, you must install 36-bit parity-type SIMMs (i.e., 8 chips plus 4 parity chips) in pairs in all banks. The combination of 32-bit non-parity (i.e., 8 chips) and 36-bit parity-type (i.e., 12 chips) memory configuration is also possible; however, this does not allow you to make use of the ECC function. The following are the possible SIMM configurations. Notice that you must install the same SIMMs in one bank. Memory Configurations Bank 0 SIMM 1 4 MB 4 MB 8 MB 8 MB 8 MB 16 MB SIMM 2 4 MB 4 MB 8 MB 8 MB 8 MB 16 MB 4 MB 8 MB 4 MB 8 MB 4 MB 4 MB Bank 1 SIMM 3 SIMM 4 Total Memory 8 MB 16 MB 16 MB 24 MB 32 MB 32 MB 2-7 Hardware Installation Memory Configurations (continued) Bank 0 SIMM 1 4 MB 8 MB 16 MB 32 MB 4 MB 8 MB 16 MB 32 MB 64 MB 4 MB 8 MB 16 MB 32 MB 64 MB 128 MB 4 MB 8 MB 16 MB 32 MB 64 MB 128 MB SIMM 2 4 MB 8 MB 16 MB 32 MB 4 MB 8 MB 16 MB 32 MB 64 MB 4 MB 8 MB 16 MB 32 MB 64 MB 128 MB 4 MB 8 MB 16 MB 32 MB 64 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 128 MB 64 MB 64 MB 64 MB 64 MB 64 MB 64 MB 64 MB 64 MB 64 MB 64 MB 32 MB 32 MB 32 MB 32 MB 32 MB 32 MB 32 MB 32 MB Bank 1 SIMM 3 16 MB 16 MB 16 MB SIMM 4 16 MB 16 MB 16 MB Total Memory 40 MB 48 MB 64 MB 64 MB 72 MB 80 MB 96 MB 128 MB 128 MB 136 MB 144 MB 160 MB 192 MB 256 MB 256 MB 264 MB 272 MB 288 MB 320 MB 384 MB 512 MB Make sure that you install the same SIMM type for each bank. Do not install memory modules that contain more than 24 chips. These modules exceed the ASIC specification. Doing so may result in unstable system performance. 2-8 Hardware Installation 2.6.1 Installing a SIMM Observe the ESD precautions when installing components. Follow these steps to install a SIMM: 1. Slip a SIMM at a 45 ° angle into a socket. If the SIMM does not completely fit into the socket, reverse the SIMM orientation. The SIMM has a curved edge indicating pin 1 that ensures installation in one direction only. curved edge Be careful when inserting or removing SIMMs. Forcing a SIMM in or out of a socket can damage the socket or the SIMM (or both). 2. Gently push the SIMM up until the pegs of the socket slip into the holes on the SIMM and the holding clips lock the SIMM into a vertical position. The SIMM should be at a 90 angle when installed. 2-9 Hardware Installation 2.6.2 Removing a SIMM To remove a SIMM: 1. Press the holding clips on both sides of the SIMM outward to release it. 2. Press the SIMM downward to about a 45° angle. 3. Gently pull the SIMM out of the socket. 2-10 Hardware Installation 2.7 Customizing your Hardware Setup You may customize your hardware setup according to your desired system performance. However, doing so requires resetting of several jumpers. The onboard jumpers are normally set to its default setting. See the figure in section 2.2 for the location of the jumpers on the system board. The following sections tell how to configure the system board to meet the desired performance: 2.7.1 Setting the Voltage Regulator The jumper JP1 enables you to set the voltage of the onboard voltage regulator. The supported voltage range is from 2.1V to 3.5V. * See the following figure for the correct settings. Voltage JP1 Voltage JP1 Auto * 3.5V 3.4V 3.3V 3.2V 3.1V 3.0V 2.9V 2.8V 2.7V 2.6V 2.5V 2.4V 2.3V 2.2V 2.1V * The system can automatically detect the CPU volltage through the VID pins; therefore, by default, JP1 is set to OPEN. You do not need to set the voltage regulator setting. 2-11 Hardware Installation 2.7.2 Disabling the Onboard Super I/O Control ler The board is preset by the manufacturer with the onboard I/O controller enabled. In case you wish to use an external I/O controller, you need to disable the onboard I/O before the external I/O card functions. To disable, you need to reset jumper JP6 to 1-2. Disabled Enabled JP6 2.7.3 Setting the Keyboard Clock By default, the keyboard clock is set according to the ISA clock. If you want to increase the clock setting to 12 MHz by simply resetting jumper JP7 to 1-2. ISA Clock JP7 12 MHz 2.7.4 Disabling the PS/2 Mouse Function The PS/2 mouse function is normally enabled and occupies IRQ12. To Enabled JP8 reassign IRQ12 to another function, you need to disable the PS/2 mouse function by setting jumper JP8 2-3 and changing the BIOS setting (see Chapter 3). Disabled 2-12 Hardware Installation 2.7.5 Enabling the Intel Flash ROM Boot Block Programming The Intel Flash ROM has two areas that can be programmed separately: BIOS area. The jumpers JP11 and JP12 allow you to program the Flash ROM boot block. By default, the boot block program function is enabled and both JP11 and JP12 are set to 1-2. Reserved JP11 JP12 the Enabled (default) 8KB boot block and the 120KB main The jumper setting shown above applies only for Intel Flash ROM. Do not change the default setting of JP11 and JP12. Doing so modifies the main BIOS area but not the boot block, causing the BIOS to become inconsistent. This may result in serious system damage. 2.7.6 Selecting the Power Switch Type The jumper JP14 allows you to set the power switch type that you want to support, i.e., either the toggle type or the momentary type. However, before you set this jumper, make sure that you know your power switch type. Momentary type switch Toggle type switch JP14 2-13 Hardware Installation To differentiate a toggle type from a momentary type, check the On and Off switch position. In a toggle type switch, a pressed switch indicates On position while a normal switch position indicates Off. In a momentary type, the switch position does not change for both modes. To support a toggle type switch, close pins 2-3 of JP14. Close all pins (1-4) to support a momentary type switch. 2.7.7 Clearing the CMOS You need to clear the CMOS if you forget your system password. To clear the CMOS, do the following steps: Before you proceed, check your onboard CMOS chip. The learing procedures vary depending on the CMOS chip type. Read the CMOS chip label to determine the chip type. For Dallas DS12887A: JP10 1. 2. Turn off the system power. Locate JP10 and short pins 1-2 for a few seconds.
