HOW TO SET THE JUMPERS You can configure your board by setting the jumpers. Jumper is consists of two or three metal pins with a plastic base mounted on the card, and by using a small plastic "cap", Also known as the jumper cap (with a metal contact inside), you are able to connect the pins. So you can set-up your hardware configuration by "opening" or "closing" pins. The jumper can be combined into sets that called jumper blocks. When the jumpers are all in the block, you have to put them together to set up the hardware configuration. The figure below shows how this looks like. JUMPERS AND CAPS If a jumper has three pins (for example, labelled PIN1, PIN2, and PIN3), You can connect PIN1 & PIN2 to create one setting and shorting. You can either connect PIN2 & PIN3 to create another setting. The same jumper diagrams are applied all through this manual. The figure below shows what the manual diagram looks like and what they represent.

INTRODUCTION This chapter will show you the function of the BIOS in managing the features of your system. The EB-381LF 3.5” Embedded Board is equipped with the BIOS for system chipset from Award Software Inc. This page briefly explains the function of the BIOS in managing the special features of your system. The following pages describe how to use the BIOS for system chipset Setup menu. Your application programs (such as word processing, spreadsheets, and games) rely on an operating system such as DOS or OS/2 to manage such things as keyboard, monitor, disk drives, and memory. The operating system relies on the BIOS (Basic Input and Output system), a program stored on a ROM (Read-only Memory) chip, to initialize and configure your computer's hardware. As the interface between the hardware and the operating system, the BIOS enables you to make basic changes to your system's hardware without having to write a new operating system. The following diagram illustrates the interlocking relationships between the system hardware, BIOS, operating system, and application program: Page: 4-2 EB-381LF USER′S MANUAL Chapter 4 Award BIOS Setup 4-2. ENTERING SETUP When the system is powered on, the BIOS will enter the Power-On Self Test (POST) routines and the following message will appear on the lower screen: PRESS <DEL> TO ENTER SETUP, ESC TO SKIP MEMORY TEST As long as this message is present on the screen you may press the <Del> key (the one that shares the decimal point at the bottom of the number keypad) to access the Setup program.

Page: 4-4 EB-381LF USER′S MANUAL Chapter 4 Award BIOS Setup IDE Primary Master / Slave: IDE Secondary Master / Slave: The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detect its specifications during POST, every time system boots. If you do not want to select drive type AUTO, other methods of selecting drive type are available: 1. Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for hard drive types 1 through 45. 2. Select USER and enter values into each drive parameter field. 3. Use the IDE HDD AUTO DETECTION function in Setup. Here is a brief explanation of drive specifications: Type: The BIOS contains a table of pre-defined drive types. Each defined drive type has a specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors. Drives whose specifications do not accommodate any predefine type are classified as type USER. • Size: Disk drive capacity (approximate). Note that this size is usually greater than the size of a formatted disk given by a disk-checking program. • Cyls: number of cylinders. • Head: number of heads. • Precomp: write precompensation cylinders. • Landz: landing zone. • Sector: number of sectors. • Mode: Auto, Normal, Large or LBA. Auto: The BIOS automatically determines the optimal mode. Normal: Maximum number of cylinders, heads, sectors supported are 1024, 16 and 63. Large: For drives that do not support LBA and have more than 1024 cylinders. EB-381LF USER′S MANUAL Page: 4-5 Chapter 4 Award BIOS Setup LBA (Logical Block Addressing): During drive accesses, the IDE controller transforms the data address described by sector, head and cylinder number into a physical block address, significantly improving data transfer rates. For drives greater than 1024 cylinders. DRIVE A AND DRIVE B: Select the type of floppy disk drive installed in your system. The available options are 360KB 5.25in, 1.2KB 5.25in, 720KB 3.5in, 1.44MB 3.5in, 2.88MB 3.5in and None. VIDEO: This category selects the type of video adapter used for the primary system monitor.
