[. . . ] Configure Memory Your board comes with two DIMM sockets, providing support for up to 256MB of main memory using DIMM modules from 8MB to 128MB. For 66MHz front side bus CPUs use 12ns or faster memory; for 100MHz front side bus CPUs use 8ns (100MHz, PC100 compliant) memory. Memory Configuration Table Number of Memory Modules 1 DIMM 1 1st 1st SDRAM 8/16/32/64/128 Mbytes 2nd DIMM 2 Hardware Installation 2 RAM Type Memory Module Size (MB) Important: It is of prime importance that you install DIMM modules as outlined in the table above in order to preserve signal integrity on 100MHz front side bus systems. Step 4. Set SW1 for power up FSB clock and AGP bus clock. SW1 is used to adjust AGP bus clock frequency depending on the value of the front side bus (FSB) clock, also the setting of the SW1 determines the power up FSB clock which will remain effective until the BIOS set the FSB clock to the CMOS setting. SW1 Setting Power up FSB Clock 66MHz AGP Clock AGP Clock = FSB Clock ÷ 1 AGP Clock 100MHz = FSB Clock ÷ 1. 5 Note1: The factory default setting for SW1 (Power up FSB clock and AGP bus clock) is 66MHz. CPUs that run on 100MHz may not boot at this frequency, so check SW1 before booting for the first time. Also, if the user changes the CPU, care should be taken to set SW1 in accordance with the FSB Frequency of the new CPU. Note2: The specification of maximum AGP bus Clock frequency is 66. 6MHz. Set SW1 to open when you use a FSB 66MHz CPU but want to over clock the FSB clock to 100MHz via the BIOS setting. 8 SY-6ZB Quick Start Guide Step 5. Set the CPU Frequency You do not need to set any jumper for the CPU frequency. Instead, CPU setting are changed through the BIOS [CHIPSET FEATURES SETUP]. Please refer to Chapter 3 - Quick BIOS Setup for details on how to set the Slot 1 processor frequency. Step 6. Enable/Disable Power-On by Keyboard (JP50) You can choose to enable the Power-On by Keyboard function by shorting pin 2-3 on jumper JP50, otherwise, short pin 1-2 to disable this function. Power-On by Keyboard Enable Disable Short pin 2-3 to enable the Short pin 1-2 to disable the Power-On by Keyboard function. JP50 Setting 1 2 3 1 2 3 Important: When using the Power-On by Keyboard function, please make sure the ATX power supply can take at least 720mA load on the 5V Standby lead (5VSB) to meet the standard ATX specification. Step 7. Clear CMOS Data (JP5) Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5 for at least 5 seconds, and then by shorting pin 1-2 to retain new settings. Available [CPU Speed] settings on your SY-6ZB Motherboard are detailed in the following table. If you set this field to [Manual], you are then required to fill in the next two consecutive fields: (1) the [CPU Host Clock], and (2) the [CPU Ratio]. CPU Frequency 233MHz (66 x 3. 5) 266MHz (66 x 4. 0) 300MHz (66 x 4. 5) 333MHz (66 x 5. 0) 366MHz (66 x 5. 5) 400MHz (66 x 6. 0) 433MHz (66 x 6. 5) 350MHz (100 x 3. 5) 400MHz (100 x 4. 0) 450MHz (100 x 4. 5) 500MHz (100 x 5. 0) 550MHz (100 x 5. 5) 600MHz (100 x 6. 0) Select the working frequency of your Pentium® III, Pentium® II, CeleronTM processor among these preset values. Note: Mark the checkbox that corresponds to the working frequency of your Pentium® III, Pentium® II, CeleronTM processor in case the CMOS configuration should be lost. Note: if you use Bus Frequencies of 75 MHz, make sure that your PCI cards can cope with the higher PCI clock. Step 4. Select [SAVE & EXIT SETUP] Press <Enter> to save the new configuration to the CMOS memory, and continue the boot sequence. 11 Quick BIOS Setup SY-6ZB Quick Start Guide 4 The SOYO CD The SOYO-CD will NOT autorun if you use it on an Operating System other than Windows 9x or NT. Your SY-6ZB Motherboard comes with a CD-ROM labeled "SOYO CD. " The SOYO CD contains (1) the user's manual file for your new Motherboard, (2) the drivers software available for installation, and (3) a database in HTML format with information on SOYO Motherboards and other products. Step 1. Insert the SOYO CD into the CD-ROM drive The SOYO CD will auto-run, and the SOYO CD Start Up Menu will be shown as below. The SOYO CD (SOYO CD Start Up Program Menu) If you use Windows 95/98, the SOYO CD Start Up Program automatically detects which SOYO Motherboard you own and displays the corresponding model name. Step 2. Read SOYO [6ZB] Manual Click the Read Manual button to open the user's manual file of your Motherboard. 12 SY-6ZB Quick Start Guide Please note that if the Start Up program was unable to determine which SOYO Motherboard you own, the manual selection menu will pop up, as shown below. Then select the user's manual file that corresponds to your Motherboard model name and click OK. SOYO CD Manuals Please select your manual in the box below and click OK. 686 boards: 586 boards: 6ZB OK Back (Manual Selection Menu) The user's manual files included on the SOYO CD can be read in PDF (Postscript Document) format. In order to read a PDF file, the appropriate Acrobat Reader software must be installed in your system. Note: The Start Up program automatically detects if the Acrobat Reader utility is already present in your system, and otherwise prompts you on whether or not you want to install it. You must install the Acrobat Reader utility to be able to read the user's manual file. Follow the instructions on your screen during installation, then once the installation is completed, restart your system and re-run the SOYO CD. Step 3. Install Drivers Click the Install Drivers button to display the list of drivers software that can be installed with your Motherboard. The Start Up program displays the drivers available for the particular model of Motherboard you own. We recommend that you only install those drivers. 13 The SOYO CD SY-6ZB Quick Start Guide The following drivers are available for Windows 95 Driver Installation Please select the driver you want to install and click OK, You will have to restart your system after installation. [. . . ] Then re-run the SOYO CD and you will be able to browse the SOYO HTML database.
