Place Date Legal Signature of Authorized Person System Overview Chapter 1 System Overview 1.1 Introduction ROBO-8612VGA, PICMG 1.0 SBC supports Intel® Pentium® III / Celeron processor, DDR SDRAM, Video display, Gigabit Ethernet and Audio. The ROBO-8612VGA adopts VIA CLE266 chipset that support Intel® Pentium® III, & Celeron processor with DDR 200/266 up to 2GB system memory. This special processor and memory combination provides user a lower TDP (Thermal Design Power) processor with smaller cooler and better availability of memory. Under critical environment and space limitation consideration, some users dare not use bigger TDP processor or cannot use processor that is bundled with big cooler. Therefore Intel® Pentium® III level processor is still the best choice. SBC designed with old chipset only supports SDRAM, along with time shifting SDRAM availability is getting worse and worse. It is wonderful idea to have common memory modules in stock for both P3 and P4 based system. In additional to the features of processor and system memory, CLE266 also integrates AGP 4X equivalent performance graphics accelerator. With SMA (Shared Memory Architecture), it shares 16, 32 or 64MB system memory for frame buffer. Besides, ROBO-8612VGA also supports one Gigabit Ethernet, six USB 2.0 ports and Audio in/out. Ethernet and USB port become very popular interface for data upstream and downstream interfaces. A higher bandwidth Ethernet port speeds up transactions with server, to have Gigabit grade Ethernet is mandatory. USB is a very friendly interface; its hot-swappable, rich devices and easily installation are making it getting more and more popular. With VIA chipset supply life cycle guarantee, the chipset shall continue going till the end of year 2007. And last buy notice will be issued at least six months ahead of EOL (End-of-Life).

The additional information is enclosed to help set up onboard PCI device and handle WDT operation in software programming. 3.1 Socket 370 Celeron/Pentium-III Processor Installing S370 CPU 1) Lift the handling lever of CPU socket outwards and upwards to the other end. 2) Align the processor pins with pin holes on the socket. Make sure that the notched corner or dot mark (pin 1) of the CPU corresponds to the socket’s bevel end. Then press the CPU gently until it fits into place. If this operation is not easy or smooth, don’t do it forcibly. You need to check and rebuild the CPU pin uniformly. 3) Push down the lever to lock processor chip into the socket. 4) Follow the installation guide of cooling fan or heat sink to mount it on CPU surface and lock it on the socket 370. Removing CPU 1) Unlock the cooling fan first. 2) Lift the lever of CPU socket outwards and upwards to the other end. 3) Carefully lift up the existing CPU to remove it from the socket. 4) Follow the steps of installing a CPU to change to another one or place handling bar to close the opened socket. Configuring System Bus ROBO-8612VGA will automatically detect system bus based on the type of CPU used. However, users may configure CPU core/bus ratio in BIOS setup menu for engineering sample processors. ROBO-8612VGA User’s Manual 3-1 System Installation 3.2 Main Memory Two DIMM sockets support 200/266 DDR-SDRAM up to 2GB System Memory. ROBO-8612VGA will automatically detect memory clock, based on the processor and DDR-SDRAM used. For system compatibility and stability, do not use memory module without brand. ROBO-8612VGA uses non-ECC, non-buffered DIMMS only. Randomly installing DIMM in any one of the DIMM sockets is allowed. User may install different size of DRAM module on DIMM1, DIMM2 or all to make the system boot. Be cautious with the contact and lock mechanism of memory module and socket, it may impact on the system reliability. Follow normal procedures to install your DRAM module into memory socket. Before locking, make sure that all modules have been fully inserted into the card slots. Note: (1) To maintain system stability, do not change any of DRAM parameters in BIOS setup to upgrade system performance without acquiring technical information. (2) Due to VIA CLE266 chipset limitation, the type of DDR-SDRAM with ECC function is not supported. In the event of ECC DDR-SDRAM being adopted, ECC function is NOT supported while ECC DDR-SDRAM can act only as a normal DDR-SDRAM without causing any error. (3) Due to VIA CLE266 chipset limitation, Buffered (Registered) DDR-SDRAM is not supported. Buffered DDR-SDRAM will simply freeze up the system. ROBO-8612VGA User’s Manual 3-2 System Installation 3.3 Installing the Single Board Computer To install ROBO-8612VGA into standard chassis or proprietary environment, you need to perform the following : Step 1 : Check all jumpers setting on proper position Step 2 : Install and configure CPU and memory module on right position Step 3 : Place ROBO-8612VGA into the dedicated position in your system Step 4 : Attach cables to existing peripheral devices and secure it WARNING Please ensure that single board computer is properly inserted and fixed by mechanism.

ROBO-8612VGA User’s Manual 4-21 BIOS Setup Information 4.13 Supervisor/User Password Setting You can set either supervisor or user password, or both of then. The differences between are: Set Supervisor Password: can enter and change the options of the setup menus. Set User Password: just can only enter but do not have the right to change the options of the setup menus. When you select this function, the following message will appear at the center of the screen to assist you in creating a password. ENTER PASSWORD Type the password, up to eight characters in length, and press . The password typed now will clear any previously entered password from CMOS memory. You will be asked to confirm the password. Type the password again and press . You may also press to abort the selection and not enter a password. To disable a password, just press when you are prompted to enter the password. A message will confirm the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup freely. PASSWORD DISABLED When a password has been enabled, you will be prompted to enter it every time you try to enter Setup. This prevents an unauthorized person from changing any part of your system configuration. Additionally, when a password is enabled, you can also require the BIOS to request a password every time your system is rebooted. This would prevent unauthorized use of your computer. You determine when the password is required within the BIOS Features Setup Menu and its Security option (see Section 3). 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.

Y Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays on after you turn your system off. The next time you boot your computer, the BIOS configures your system according to the Setup selections stored in CMOS. After saving the values the system is restarted again. Exit Without Saving Pressing on this item asks for confirmation: Quit Without Saving (Y/N)? N This allows you to exit Setup without storing in CMOS any change. The previous selections remain in effect. This exits the Setup utility and restarts your computer. ROBO-8612VGA User’s Manual 4-23 Troubleshooting Chapter 5 Troubleshooting This chapter provides a few useful tips to quickly get ROBO-8612VGA running with success. As basic hardware installation has been addressed in Chapter 2, this chapter will primarily focus on system integration issues, in terms of BIOS setting, and OS diagnostics. 5.1 BIOS Setting It is assumed that users have correctly adopted modules and connected all the device cables required before turning on AT power. CPU, CPU fan, CPU fan power cable, 184-pin DDR SDRAM, keyboard, mouse, floppy drive, IDE hard disk, printer, VGA connector, device power cables, ATX accessories are good examples that deserve attention. With no assurance of properly and correctly accommodating these modules and devices, it is very possible to encounter system failures that result in malfunction of any device. To make sure a successful power up with ROBO-8612VGA, it is recommended, when going with the boot-up sequence, to hit “DEL” key and enter the BIOS setup menu to tune up a stable BIOS configuration so that you can wake up your system far well. Loading the default optimal setting When prompted with the main setup menu, please scroll down to “Load Optimal Defaults”, press “Enter” and “Y” to load in default optimal BIOS setup. This will force your BIOS setting back to the initial factory configuration. It is recommended to do this so you can be sure the system is running with the BIOS setting that Portwell has highly endorsed. As a matter of fact, users can load the default BIOS setting any time when system appears to be unstable in boot up sequence. Auto Detect Hard Disks In the BIOS => Standard CMOS setup menu, picks up any one from Primary/Secondary Master/Slave IDE ports, and press, “Enter”. Setup the selected IDE port and its access mode to “Auto”. This will force system to automatically pick up the IDE devices that are being connected each time system boots up. Improper disable operation There are various occasions where users disable a certain device/feature in one application through BIOS setting. These variables may not be set back to the original values when needed. These devices/features will certainly fail to be detected. ROBO-8612VGA User’s Manual 5-1 Troubleshooting When the above conditions happen, it is strongly recommended to check the BIOS settings. Make sure certain items are set as they should be. These include the floppy drive, COM1/COM2 ports, parallel port, USB ports, external cache, on-board VGA and Ethernet. It is also very common that users would like to disable a certain device/port to release IRQ resource. A few good examples are Disable COM1 serial port to release IRQ #4 Disable COM2 serial port to release IRQ #3 Disable parallel port to release IRQ #7 Disable PS/2 mouse to release IRQ #12 ,…, etc. A quick review of the basic IRQ mapping is given below for your reference. IRQ# Description IRQ #0 System Counter IRQ #1 Keyboard IRQ #3 COM2 IRQ #4 COM1 IRQ#5 Multimedia Device RQ #6 Floppy Disk Controller IRQ #7 Printer Port (Parallel Port) IRQ #8 System CMOS / Real time Clock IRQ #9 Microsoft ACPI-Compliant System IRQ #10 USB 1.0/1.1 UHCI Controller IRQ #10 USB 1.0/1.1 UHCI Controller IRQ #11 USB 2.0 ECHI Controller IRQ #11 Network Controller IRQ #12 PS/2 Compatible Mouse IRQ #14 VIA Bus Master PCI IDE Controller IRQ #14 Primary IDE Controller IRQ #15 VIA Bus Master PCI IDE Controller IRQ #15 Secondary IDE Controller It is then very easy to find out which IRQ resource is ready for additional peripherals. If IRQ resource is not enough, please disable some devices listed above to release further IRQ numbers as desired. ROBO-8612VGA User’s Manual 5-2 Troubleshooting 5.2 FAQ Unboot issues Symptom: After installing CPU and everything required, but why my ROBO- 8612VGA is still not working? Solution: Please make sure that you’ve used the backplane, which follows PICMG spec. Symptom: After shutting down Windows, why my system failed to boot up again? Solution: First, please make sure your ACPI in the BIOS is disabled. Indeed, when system is running with AT power supply and enabled ACPI, it will cause system to failed to boot up. That’s because system will go to sleeping mode as shutting down under Windows. To solve this problem, you have to either clean CMOS or push ATX Power button. Symptom: My ROBO-8612VGA just keeps beeping, and nothing has been shown on the screen? Solution: As a matter of fact, each beep sound represents different definition of error message. Therefore, please refer to the table as follow, Beep sounds Meaning Action One long beep with one DRAM error Change DRAM or reinstall it short beeps One long beep constantly DRAM error Change DRAM or reinstall it One long beep with two Monitor or Display Please check Monitor connector short beeps Card error whether it inserts properly Beep rapidly Power error warning Please check Power mode setting Information & Support Q: I am using an ATA-66 (or 100) hard drive, how can I know that ATA-66 function is started? A: First of all, you need to use the 80-pin ATA-66 IDE flat cable to have this function ready. During POST, you can see ATA-66 (or 100) message while hard drive is being detected. Besides, after Microsoft series OS installation successfully, you must install ATA-66/100 driver, then the function can be active. ROBO-8612VGA User’s Manual 5-3 Troubleshooting Q: I am using an ATA-66 or 100 hard drive, how can I know that ATA 66/100 is active? A: As matter of fact, you need to use 80 pins ATA-66 IDE cable to enable ATA 66 function. While POST stage of detecting hard drive, you will see ATA – 66/100 message. Besides, after installing Microsoft Windows system, you also need to install ATA 66/100 driver. Otherwise, this function won’t be active in Windows. Q: After setting up my serial port from RS-232 to RS-485, why my serial port still cannot work. A: Unlike RS-232, RS-485’s signal is differential signal. Therefore, its data must connect to same definition of pins. For example, there are only two pins in RS- 485, which are DATA – and DATA +. Its connection must be “DATA – connects to DATA –“, and “DATA + connects to DATA +”. Otherwise, RS-485 won’t be able to transfer its data. Q: After installing Compact Flash, why the device on Secondary has been missing? A: Compact Flash is set to master on Secondary channel. If you accidentally set any IDE device to the same channel as Compact Flash default does. Your device will work improperly; the setting of Compact Flash is unchangeable. Q: I am a customer of Portwell, where can I get new BIOS to update my SBC? A: Indeed, you can always go to Portwell Download center to download update BIOS. Besides, before downloading anything, please mail us to get your download account number. Portwell Download Center http://www.portwell.com.tw/download.asp To request your Account Number for Download Center, please fill out the information form on our Internet after selecting the information that you want.
