A jumper is the simplest kind of electrical switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper, connect the pins with the clip. To "open” a jumper, remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case, connect either pins 1 and 2 or 2 and 3. 3 2 1 Open Closed Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 Open Closed Closed 2-3 A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representa- tive before you make any changes. Generally, a standard cable is all that is needed to make most connections. 38 PPC-57 User's Manual Warning! Always completely disconnect the power cord from your board whenever you are working on it. Do not make connections while the power is on, because sensitive electronic components can be damaged by a sudden rush of power. Caution! Always ground yourself to remove any static charge before touching the board. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis.

Chapter 4 The Engine of the PPC-57 (PCM-3866) 41 Connecting drives is done in a daisy-chain fashion and requires a 1 x 44-pin to 2 x 44-pin flat-cable connector. Wire number 1 on the cable is red or blue, and the other wires are gray. 1. Connect one end of the cable to CN3. Make sure that the red (or blue) wire corresponds to pin 1 on the connector, which is labeled on the board (on the right side). 2. Plug the other end of the cable into the Enhanced IDE hard drive, with pin 1 on the cable corresponding to pin 1 on the hard drive. (See your hard drive's documentation for the location of the connector.) Connect a second drive as described above. Unlike floppy drives, IDE hard drives can connect to either end of the cable. If you install two drives, you will need to set one as the master and one as the slave by using jumpers on the drives. If you install just one drive, set it as the master.

It is supported by all major network operating systems and is 100% Novell NE2000 compatible. Configuration of the Ethernet is very easy and can be done via the RSET8019.EXE program included on the utility disk. This program enables you to view the current Ethernet configuration, to reconfigure the Ethernet interface (IRQ, I/O address, etc.), and to execute useful diagnostic functions. (See Chapter 5 for detailed information.) The RSET8019.EXE program provides two ways to configure the Ethernet interface. Configuration can be done automatically when you choose the PnP (Plug and Play) option. Alternatively, when you choose the jumperless option, the following IRQ and I/O address settings are available (see over).

AMI System BIOS is covered in Chapter 6. Sections include: • Introduction • Utility Disk • How to Update BIOS • Ethernet Utility CHAPTER 5.1 Introduction The PCM-3866 system BIOS and custom drivers are located in a 128 KB, 32-pin Flash ROM device, designated U5. A single Flash chip holds the system BIOS and VGA BIOS. The display type can be configured via software. This method minimizes the number of chips and eases configuration. You can change the display BIOS simply by reprogramming the Flash chip. 5.2 Utility Disk The PCM-3866 is supplied with a software utility disk. This disk contains the necessary files for setting up the VGA display. Directories and files on the disk are as follows: README.DOC AMIFLASH.EXE 57SYS.ROM 57CSTN.ROM 57MONO.ROM ETHERNET.EXE ON.COM OFF.COM AMIFLASH.EXE This program allows you to write the VGA BIOS files to the BIOS Flash ROM. All the VGA files are already formatted for the PCM-3866 with .ROM extensions. See README.DOC. They are custom written and can be made available upon request. 57SYS.ROM This binary file contains the system BIOS. 57CSTN.ROM Supports 320 x 240 color STN DD 8-bit displays (KYOCERA KCS3224ASTT-X6 5.7"). 57MONO.ROM Supports 320 x 240 monochrome displays (KYOCERA KS3224ASTT-FW-X1 5.7"). 56 PPC-57 User's Manual ETHERNET.EXE This is a compressed file containing ethernet drivers and the utility for the Realtek 8019AS chip (see page 58). 5.3 How to Update BIOS You can program your on-board BIOS as follows: 1. Apply power to the PCM-3866 with a color STN display attached. This is the default setting for the PCM-3866. Make sure that the AMIFLASH.EXE and *.ROM files are located in the working drive. Note: Make sure that you do not run AMIFLASH.EXE while your system is operating in EMM386 mode. 2. At the prompt, type AMIFLASH.EXE and press . The VGA configuration program will then display the VGA Setup screen. 3. At the prompt, type in the ROM file which supports your display. When you are sure that you have entered the file name correctly, press . The screen will display "Flash EPROM programming is going to start". If you wish to continue, press Y. If you change your mind or have made a mistake, press N to abort and end the setup procedure. 4. When programming is finished, press any key to reboot. The new VGA configuration will then write to the ROM BIOS chip. This configuration will remain the same until you run the AMIFLASH.EXE program and change the settings. Chapter 5 Software Configuration 57 5.4 Ethernet Utility The PPC-57 Ethernet driver utility disk (ETHERNET.EXE) contains files required for installing and setting up the Ethernet controller. Copy ETHERNET.EXE to a selected drive. You can extract the file by typing: ETHERNET-Y.

Upon receipt of the PPC-57, you should use RSET8019.EXE to config- ure your system for the working environment. If by chance the Ethernet EEPROM is corrupted, the PG8019.EXE program allows you to configure the card. 8019AS.CFG This file contains the configuration parameters that are used by PG8019.EXE. Users can configure Ethernet settings by using the PG8019.EXE programming utility. Follow these steps: 1. Edit the 8019AS.CFG file by using any text editor (e.g. Windows Notepad, or the MS-DOS Edit command). Modify "IOBASE" and "IRQ" to the setting for your system. Exit after you have finished modifying and saving the file. 2. Make sure that PG8019.EXE and 8019AS.CFG are under the same directory. Execute the programming utility. C:\PG8019 8019AS.CFG 3. Reboot your computer. Ethernet software configuration The PPC-57's on-board Ethernet interface supports all major network operating systems. To configure the media type, view the current configuration, or run diagnostics, follow these steps: 1. Turn on the power to the PPC-57. Ensure that the RSET8019.EXE file is located on the working drive. 2. At the prompt, type RSET8019.EXE and press . The Ethernet configuration program will then be displayed. Chapter 5 Software Configuration 59 3. All the available options for the Ethernet interface will be displayed. Highlight the option to be changed using the Up and Down keys. To change a selected item, press , whereupon a screen will appear with the available options. Highlight your option and press . Each highlighted option has a helpful message guide displayed at the bottom of the screen with additional information. 4. After you have made your selections and are sure that this is the configuration you want, press Esc. A prompt will appear asking if you want to save the configuration. Press Y if you want to save. The Run Diagnostics item in the Ethernet Main Menu also offers three very useful diagnostic functions: 1. Run EEPROM test. 2. Run Diagnostics on Board. 3. Run Diagnostics on Network. Each option has its own display screen which shows the format and result of any diagnostic test undertaken. 60 PPC-57 User's Manual 6 AMI Flash BIOS Setup This chapter describes how to set BIOS configuration data. Since the PPC-57's LCD display is only one quarter the size of a normal VGA display, the messages that appear on your screen will be only one quarter of the messages that appear in this manual. Any screen display illustrated in this manual is merely for your reference, to assist you in setting up BIOS. CHAPTER 6.1 System Test and Initialization These routines test and initialize board hardware. If the routines encounter an error, you will either hear a few short beeps or see an error message on the screen. There are two kinds of errors: fatal and non-fatal. The system can usually continue the boot sequence with non-fatal errors. Non-fatal error messages usually appear on the screen along with the following instruction: press to RESUME Write down the message and press the F1 key to continue the boot sequence. System configuration verification These routines check the current system configuration against the values stored in the card's CMOS memory. If they do not match, the program outputs an error message. You will then need to run the BIOS setup program to set the configuration information in memory. There are three situations in which you will need to change the CMOS settings: 1. You are starting your system for the first time. 2. You have changed the hardware attached to your system. 3. The CMOS memory has lost power and the configuration information has been erased. The PPC-57 board's CMOS memory has an integrated lithium battery backup. The battery backup should last ten years in normal service. When it finally runs down, you will need to replace the complete unit. 62 PPC-57 User's Manual 6.2 AMI BIOS setup Setup program initial screen AMI's Flash BIOS has a built-in setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backup CMOS RAM, so that it retains the setup information when the power is turned off. Entering setup Power on the computer and press immediately. This will allow you to enter Setup. Chapter 6 AMI Flash BIOS Setup 63 Standard CMOS setup When you choose the STANDARD CMOS SETUP option from the INITIAL SETUP SCREEN menu, the screen shown below is displayed.

It loads the default system values directly from ROM. If the stored record created by the setup program becomes corrupted (and therefore unusable), these defaults will load automatically when you turn on the PPC-57. You can load optimal default settings by choosing "Y" in the screen above. The high-performance settings are the most favor- able values for optimum system performance. Chapter 6 AMI Flash BIOS Setup 67 Save settings and exit If you select this option and press , the values entered in the setup utilities will be recorded in the chipset's CMOS memory. The microprocessor will check this every time you turn your system on and compare this to what it finds as it checks the system. This record is required for the system to operate. Exit without saving Selecting this option and pressing lets you exit the setup program without recording any new values or changing old ones. 68 PPC-57 User's Manual 7 SVGA Setup The PPC-57 features an on-board flat panel/VGA interface.

Before you attempt to install any driver or utility you should know how to copy files from a floppy disk to a directory on the hard disk, understand the MS-DOS directory structure, and know how to format a floppy disk. If you are uncertain about any of these concepts, please refer to the DOS or Windows user reference guides for more information before you proceed with the installa- tion. Before you begin Before you begin installing software drivers, you should make a backup copy of the display driver diskette and store the original in a safe place. The display driver diskette contains drivers for several versions of certain applications. You must install the correct version of the driver in order to work properly, so make sure you know which version of the application you have. 72 PPC-57 User's Manual Windows These drivers are designed to work with Microsoft Windows 3.1. You may install these drivers through Windows or in DOS. Windows setup Step 1: Install Windows as you normally would for a VGA display. Run Windows to make sure that it is working correctly. Step 2: Place the display driver diskette in drive A. In Windows Program Manager, choose File from the Options Menu. Then from the pull-down menu, choose Run . . . .
