2-3. HOW TO SET THE JUMPERS

You can configure your board by setting 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 "open" or "close" 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 examples, 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 diagrams look and what they represent.

3-8. WATCHDOG TIMER CONFIGURATION

The I/O port address of the watchdog timer is 2E(hex) and 2F(hex). 2E (hex) is the
address port. 2F(hex) is the data port. User must first assign the address of register by
writing address value into address port 2E(hex), then write/read data to/from the
assigned register through data port 2F (hex).

Configuration Sequence

To program W83627HF configuration registers, the following configuration sequence
must be followed:

(1) Enter the extended function mode
(2) Configure the configuration registers
(3) Exit the extended function mode

(1) Enter the extended function mode

To place the chip into the extended function mode, two successive writes of 0x87
must be applied to Extended Function Enable Registers (EFERs, i.e. 2Eh).

(2) Configurate the configuration registers

The chip selects the logical device and activates the desired logical devices through
Extended Function Index Register (EFIR) and Extended Function Data Register
(EFDR). EFIR is located at the same address as EFER, and EFDR is located at
address (EFIR+1).
First, write the Logical Device Number (i.e.,0x07) to the EFIR and then write the
number of the desired logical device to the EFDR. Secondly, write the address of the
desired configuration register within the logical device to the EFIR and then write (or
read) the desired configuration register through EFDR.

(3) Exit the extended function mode

To exit the extended function mode, one write of 0xAA to EFER is required. Once
the chip exits the extended function mode.

Example Program

1. Enable watchdog timer and set 30 sec. as timeout interval

4-1. INTRODUCTION

This chapter will show you the function of the BIOS in managing the
features of your system. The EPC-5500 Intel® Pentium® M Embedded PC
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:

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.

Chipset Features Setup Screen

This parameter allows you to configure the system based on the specific
features of the installed chipset. The chipset manages bus speed and
access to system memory resources, such as DRAM and the external cache.

It also coordinates communications between conventional ISA bus and the
PCI bus. It must be stated that these items should never need to be altered.
The default settings have been chosen because they provide the best opera­ting conditions for the system. The only time you might consider making
any changes would be if you discovered that data was being lost while
using your system.

DRAM TIMING BY SELECTABLE:

This allows you to select the DRAM timing.

CAS LATENCY TIME:

When synchronous DRAM is installed, the number of clock cycles of CAS
latency depends on the DRAM timing.

ACTIVE TO PRECHARGE DELAY:

This item controls the number of DRAM clocks for TRAS.

DRAM RAS# TO CAS# DELAY:

This field let’s you insert a timing delay between the CAS and RAS strobe
signals, used when DRAM is written to, read from, or refreshed. Fast gives
faster performance; and Slow gives more stable performance. This field
applies only when synchronous DRAM is installed in the system.

DRAM RAS# PRECHARGE:

If an insufficient number of cycles is allowed for the RAS to accumulate its
charge before DRAM refresh, the refresh may be incomplete and the DRAM
may fail to retain data. Fast gives faster performance; and Slow gives more
stable performance. This field applies only when synchronous DRAM is
installed in the system.

DRAM DATA INTEGRITY MODE:

Select Parity or ECC (error-correcting code), according to the type of installed
DRAM.

SYSTEM BIOS CACHEABLE:

Selecting Enabled allows caching of the system BIOS ROM at F0000h­FFFFFh, resulting in better system performance. However, if any program
writes to this memory area, a system error may result.

VIDEO BIOS CACHEABLE:

Select Enabled allows caching of the video BIOS, resulting in better system
performance. However, if any program writes to this memory area, a system
error may result.

MEMORY HOLE AT 15M-16M:

You can reserve this area of system memory for ISA adapter ROM. When
this area is reserved, it cannot be cached. The user information of
peripherals that need to use this area of system memory usually discusses their
memory requirements.

DELAYED TRANSACTION:

The chipset has an embedded 32-bit posted write buffer to support delay
transactions cycles. Select Enabled to support compliance with PCI
specification version 2.1.

AGP APERTURE SIZE:

This field determines the effective size of the Graphic Aperture used for a
particular GMCH configuration. It can be updated by the GMCH-specific
BIOS configuration sequence before the PCI standard bus enumeration
sequence takes place. If it is not updated then a default value will select an
aperture of maximum size.
