IDE1 is also known as primary channel and IDE2 as secondary channel, each channel supports two IDE devices that makes total of four devices. In order to work together, the two devices on each channel must be set differently to master and slave mode, either one can be hard disk or CDROM. The setting as master or slave mode depends on the jumper on your IDE device, please refer to your hard disk and CDROM manual accordingly. Connect your first IDE hard disk to master mode of the primary channel. If you have second IDE device to install in your system, connect it as slave mode on the same channel, and the third and fourth device can be connected on secondary channel as master and slave mode respectively. 2 1 40 39 IDE1 2 1 40 39 IDE2 Caution: The specification of IDE cable is maximum 46cm (18 inches), make sure your cable does not excess this length. Caution: For better signal quality, it is recommended to set far end side device to master mode and follow the suggested sequence to install your new device . Please refer to following figure. 2-12 Hardware Installation IDE1 (Primary Channel) Slave (2nd) Master (1st) IDE2 (Secondary Channel) Slave (4th) Master (3rd) 2. 3. 11 Hard Disk LED The HDD LED connector is marked as HDD LED on the board. This connector is designed for different type of housing, actually only two pins are necessary for the LED. If your housing has four pin connector, simply plug it in. If you have only two pin connector, please connect to pin 1-2 or pin 3-4 according to the polarity.

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 GREEN LED GND SUSPEND SW SUSPEND SW GND NC RESET GND 10 20 PANEL 1 Keylock 11 + + + + + + Suspend SW Green LED Power LED Speaker Reset 10 20 PANEL 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 2-14 Hardware Installation 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. Note: Pressing the Suspend switch allows you to manually force the system to suspend mode. However, this is possible only if the Power Management function in the BIOS Setup menu is enabled. 2. 3. 13 IrDA Connector The IrDA connector can be configured to support wireless infrared module, with this module and application software such as Laplink or Win95 Direct Cable Connection, user can transfer files to or from laptops, notebooks, PDA and printers. This connector supports HPSIR (115. 2Kbps, 2 meters), ASK-IR (19. 2Kbps) and Fast IR (4Mbps, 2 meters). 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.

Pin1 of Bank1 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). Because Pentium II 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. [. . . ] When next time, if memory is read with old number of "1", the parity error is occurred and this is called single bit error detection. Tip: The ECC mode needs 8 ECC bit for 64 bit data, because 36 bit SIMM has 4 bit more for parity, the ECC mode can be supported by two traditional parity SIMMs, it is no need to have special ECC SIMM. Each time memory is accessed, ECC bits are updated and checked by special algorithm, the ECC algorithm has the ability to detect double bit error and automatically correct single bit error. 2-20 Hardware Installation 2. 5 PCI Slot PCI Slot 4 and Slot 5 share the same interrupt INTD. Each PCI slot has four PCI interrupts aligned as listed in the table below. Most of the PCI cards use only one interrupt at location 1 (pin A6), because the chipset supports only 4 PCI interrupts.
