Power cord AC/DC Power adapter DC inlet Figure 2.5: Connect the power cord to the DC inlet 2.3 Running the BIOS Setup Program Your panel PC is likely to have been properly set up and configured by your dealer prior to delivery. You may still find it necessary to use the panel PC's BIOS (Basic Input-Output System) setup program to change system configuration information, such as the current date and time or your type of hard drive. The setup program is stored in read-only memory (ROM).
tery so that it will not be erased when you turn off or reset the system. Whenever you turn on the power, the system reads the settings stored in CMOS RAM and compares them to the equipment check conducted during the power on self-test (POST). If an error occurs, an error message will be displayed on screen, and you will be prompted to run the setup program. If you want to change the setup of BIOS, refer to Chapter 9 for more detailed information. 2.
If you are presented with the opening screen of a setup or installation program, follow the instructions on screen. The setup program will guide you through preparation of your hard drive, and installation of the operating system. If you are presented with an operating system command prompt, such as A:\>, then you must partition and format your hard drive, and manually copy the operating system files to it.

CHAPTER 4 Jumper Settings and Connectors This chapter tells how to set up the panel PC hardware, including instructions on setting jumpers and connecting peripherals, switches and indicators. Be sure to read all the safety precautions before you begin the installation procedures.
Chapter 4 Jumper Settings and Connectors 4.1 Jumpers and Connectors 4.1.1 Setting jumpers You can configure your panel PC to match the needs of your application by setting jumpers. 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, you connect the pins with the clip. To “open” a jumper you remove the clip.
4.1.2 Jumpers and switch The motherboard of the PPC-L126 has a number of jumpers that allow you to configure your system to suit your applications. The table below lists the function of each of the board’s jumpers. Table 4.1: Jumpers and their functions Label Function J1 LAN power type select J2 COM2 RS-232/422/485 setting J3 COM1/COM2/COM3/COM4 Pin 9 output type setting J4 Watchdog timer configuration J5 CMOS clear for external RTC SW2 Panel type setting (Reserved) 4.1.
4.1.4 Connectors Onboard connectors link the PPC-L126 to external devices such as external hard disk drives or floppy drives. The table below lists the function of each of the board’s connectors. Table 4.
Figure 4.
4.2 CMOS Clear for External RTC (J5) Warning! To avoid damaging the computer, always turn off the power supply before setting “Clear CMOS”. Set the jumper back to “Normal operation” before turning on the power supply. This jumper is used to erase CMOS data and reset system BIOS information. The procedure for clearing CMOS is: 1. Turn off system. 2. Short pin 2 and pin 3. 3. Return jumper to pins 1 and 2. 4. Turn on the system. The BIOS is now reset to its default setting. Table 4.
Table 4.4: COM2 RS-232/422/485 setting (J2) *RS-232 RS-422 RS-485 * default setting The IRQ and the address ranges for COM1, 2, 3, and 4 are fixed. However, if you wish to disable the port or change these parameters later you can do this in the system BIOS setup. The table overleaf shows the default settings for the panel PC’s serial ports. COM1 and COM2 are one set. You can exchange the address range and interrupt IRQ of COM1 for the address range and interrupt IRQ of COM2.
Table 4.5: Serial port default settings Port Address Range Interrupt COM1 3F8 ~ 3FF IRQ4 COM2 2F8 ~ 2FF IRQ3 COM3 3E8 ~ 3EF IRQ10 COM4 2E8 ~ 2EF IRQ5 4.3.2 COM1/COM2/COM3/COM4 pin 9 output setting (J3) Table 4.
4.4 VGA Interface The panel PC's AGP VGA interface can drive conventional CRT displays. It is also capable of driving a wide range of flat panel displays, including electroluminescent (EL), gas plasma, passive LCD and active LCD displays. 4.4.1 LCD panel power setting The panel PC's AGP SVGA interface supports 5 V and 3.3 V LCD displays. The LCD cable already has a built-in default setting. You do not need to adjust any jumper or switch to select the panel power. 4.
4.6 Wake on LAN select (J1) The PCM-L126T provides Wake-on LAN function when ATX power is used. To enable Wake-on LAN function, the J1 should be set as shown below: Table 4.

CHAPTER 9 Award BIOS Setup This chapter describes how to set BIOS configuration data.
Chapter 9 Award BIOS Setup The PPC-L126 comes with an Award BIOS chip that contains the ROM setup for your system. This chip serves as an interface between the processor and the rest of the mainboard's components. This chapter explains the information shown in the setup program and tells you how to modify the settings according to your system configuration. Some items are not explained, because it is recommended that users don’t change them.
9.2 Award BIOS setup Award’s BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed CMOS RAM so that it retains the Setup information when the power is turned off. 9.2.1 Entering setup Power on the computer and press immediately. This will allow you to enter Setup. Figure 9.
9.2.2 Standard CMOS Features setup When you choose the Standard CMOS Features option from the Initial Setup Screen menu, the screen shown below is displayed. This standard Setup Menu allows users to configure system components such as date, time, hard disk drive, floppy drive and display. Once a field is highlighted, on-line help information is displayed in the left bottom of the Menu screen. Figure 9.
9.2.3 Advanced BIOS Features setup By choosing the Advanced BIOS Features Setup option from the Initial Setup Screen menu, the screen below is displayed. Users are not encouraged to run the BIOS and Chipset Features setup programs. Your system should have been fine-tuned before shipping. Improper setup may cause the system to fail, so consult your dealer before making any changes. Figure 9.
9.2.4 Advanced Chipset Features setup By choosing the Advanced Chipset Features option from the Initial Setup Screen menu, the screen below is displayed. Figure 9.4: Advanced Chipset Features setup Note: It is strongly recommended that setup items in this section NOT be changed, because advanced knowledge is required to effect such changes.
