It may cause your system unstable if you can not meet the heat dissipation requirement from above CPU type. It is recommended to adopt larger fan on these CPU for better air flow in the system. Tip: Normally, for single voltage CPU, Vcpuio (CPU I/O Voltage) is equal to Vcore, but for CPU that needs dual voltage such as PP/MT (P55C) or Cyrix 6x86L, Vcpuio is different from Vcore and must be set to Vio (PBSRAM and Chipset Voltage). [. . . ] Attach the power LED, keylock, speaker, reset switch, suspend switch, and green mode LED connectors to the corresponding pins as shown in the figure. Some housings have a five-pin connector for the keylock and power LED Since power LED and keylock are aligned together, you can still use this kind of connector. 1 GND KEYLOCK GND RESET POWER LED SPEAKER +5V GND NC SPEAKER 11 +5V GND Reserved GND NC NC GND NC RESET GND 10 20 PANEL 1 Keylock 11 + + + + Power LED Speaker Reset 10 20 PANEL 2-18 Hardware Installation Other housings may have a 12-pin connector. If your housing has this type of connector, connect it to PANEL as shown in the figure. Make sure that the red wire of the connector is connected to +5V. 1 11 +5V 10 20 PANEL Note: If your housing comes with Turbo switch and Turbo LED connectors, you may use these connectors for Suspend switch and Green mode LED functions, respectively. If you use toggle mode Turbo switch as Suspend switch, be sure to push it twice to simulate momentary mode. Otherwise the system may hang or fail to reboot because you always force it to suspend. 2. 3. 13 IrDA Connector Serial port 2 can be configured to support wireless infrared module, with this module and application software such as Laplink, user can transfer files to or from laptops, notebooks, PDA and printers. This mainboard supports IrDA (115Kbps, 1 meter) as well as ASK-IR (19. 2Kbps). Install infrared module onto IrDA connector and enable infrared function from BIOS setup, make sure to have correct orientation when you plug onto IrDA connector.

Since Internal Modem card consumes no power when system power is off, it is recommended to use Internal Modem. To use AOpen MP32, connect 4-pin cable from RING connector of MP32 to WKUP connector on the mainboard. Refer to Appendix B "Frequently Asked Question" for detail. Pin 1 2 3 4 Description +5V SB NC RING GND Note: Wake-Up Connector and Modem Ring-On are patent applied. Tip: Not only for Modem Ring-On, there are many other possible applications. For example, IR wakeup or voice wakeup. 1 2 3 4 WKUP 2-20 Hardware Installation 2. 4 Configuring the System Memory Pin 1 of DIMM2 Pin 1 of DIMM1 Pin 1 of Bank1 Pin 1 of Bank0 This mainboard has four 72 pin SIMM sockets (Single-in-line Memory Module) and two 168 pin DIMM socket (Dual-in-line Memory Module) that allow you to install system memory from minimum 8MB up to maximum 256MB. The SIMM supported by this mainboard can be identified by 4 kinds of factors: Size: single side, 1Mx32 (4MB), 4Mx32 (16MB), 16Mx32 (64MB), and double side, 1Mx32x2 (8MB), 4Mx32x2 (32MB), 16Mx32x2 (128MB). Speed: 60ns or 70ns access time Type: FPM (Fast page mode) or EDO (Extended data output) Parity: without parity (32 bit wide) or with parity (36 bit wide). The DIMM supported by this mainboard are always 64-bit wide SDRAM. Size: single side, 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64 (64MB), 16Mx64 (128MB), and double side, 1Mx64x2 (16MB), 2Mx64x2 (32MB), 4Mx64x2 (64MB), 8Mx64x2 (128MB), 16Mx64x2 (256MB). Speed: normally marked -67, which means synchronous to maximum 67MHz. Parity: without parity (32 bit wide) Because Pentium and Pentium Pro processor has 64 bit bus width, the four SIMM sockets are arranged in two banks of two sockets each, they are Bank0 and Bank1. Both SIMMs in each bank must be in the same size and type. It is allowed to have different speed and type in different bank, for example, 70ns FPM in one bank and 60ns EDO in another bank, in such case, each bank is independently optimized for maximum performance. The memory timing requires at least 70ns fast page mode DRAM chip, but for optimum performance, 60ns EDO DRAM is recommended. 2-21 Hardware Installation Warning: The default memory timing setting is 60ns to obtain the optimal performance. Because of the specification limitation, 70ns SIMM is recommended to be used only for CPU external clock 60MHz. Tip: EDO DRAM is designed to improve the DRAM read performance.

Yes, but not tested. Warning: 64MB SIMMs using 16M by 4 bit chip (64M bit technology) are not available in the market and are not formally tested by AOpen quality test department yet. However they are supported by design specification from Intel and they will be tested as soon as they are available. Note that 64MB SIMMs using 16M by 1 bit chip (16M bit technology) have chip count exceed 24 and are strongly not recommended. [. . . ]
