 RTC & CMOS RAM Map

 Timer & DMA Channels Map

 I/O & Memory Map

~ Page 5 ~

2-1. INTERRUPT MAP

The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1570
board. They accept requests from peripherals, resolve priorities on pending interrupts in service,
issue interrupt requests to the CPU, and provide vectors which are used as acceptance indices by the
CPU to determine which interrupt service routine to execute. These two controllers are cascaded with
the second controller representing IRQ8 to IRQ15, which is rerouted through IRQ2 on the first
controller.

The following is the system information of interrupt levels:

Interrupt Level Description

3-3. HOW TO SET JUMPERS

A jumper consists of two or three metal pins with a plastic base mounted on the card, and a small plastic
cap (with a metal contact inside) to connect the pins, so you can set up your hardware configuration by
"open" or close the pins. The jumper can be combined into sets, which 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 it looks.

3 PIN

CAP

JUMPERS AND CAP
If a jumper has three pins, for example, labeled PIN1, PIN2, and PIN3, you can either connect PIN1 & PIN2
to create one setting and shorting or connect PIN2 & PIN3 to create another setting. The jumper setting
rules are applied throughout this manual.

A 32-pin DOC socket supports a DOC (Disk-on-Chip) up to 72Mb. This PnP Flash ROM DOC
can be installed as one of the user’s hard disk drive. And if set as Drive C, it can be used to boot
up the computer with MS-DOS installed. It offers much faster access than a floppy or hard disk
and greatly increases reliability under harsh environment.

5-1. BIOS SETUP OVERVIEW

The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the PCI
bus and connected devices such as the video display, diskette drive, and the keyboard.
The BIOS provides a menu-based interface to the console subsystem. The console subsystem contains
special software, called firmware that interacts directly with the hardware components and facilitates
interaction between the system hardware and the operating system.
The BIOS Default Values ensure that the system will function at its normal capability. In the worst situation
the user may have corrupted the original settings set by the manufacturer.
After the computer is turned on, the BIOS will perform diagnostics on the system and display the size of the
memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the main menu
will show on the screen.
The BIOS Setup main menu includes some options. Use the [Up/Down] arrow key to highlight the option
that you wish to modify, and then press the [Enter] key to select the option and configure the functions.

CAUTION:

1. The factory-default setting of AR-B1660 is the <Auto Configuration with Optimal Settings>. Acrosser
recommends you using the BIOS default settings unless you are very familiar with the settings function. Or
you can contact the technical support engineers (FAE).

2. If the BIOS loses the settings, the CMOS will detect the <Auto Configuration with Fail Safe Settings> to
boot the operating system. This option will reduce the performance of the system. Acrosser
recommends you choosing the <Auto Configuration with Optimal Settings> in the main menu. This option
gives best-case values that should optimize system performance.

3. The BIOS settings are described in detail in this section.

~ Page 28 ~

5-2. STANDARD CMOS SETUP

The <Standard CMOS Setup> option allows you to record some basic system hardware configurations and
set the system clock and error handling. If the CPU board is already installed in a working system, you will
not need to select this option anymore.

The user can bypass the date and time prompts by creating an AUTOEXEC.BAT file. For information
about how to create this file, please refer to the MS-DOS manual.

Floppy Setup

The <Standard CMOS Setup> option records the types of floppy disk drives installed in the system. The
available options for drives A and B are:
To enter the configuration value for a particular drive, highlight its corresponding field and then select the
drive type using the left-or right-arrow key.

Hard Disk Setup

The BIOS supports various types for user settings, The BIOS supports <Pri Master> and <Pri Slave> so the
user can install up to two hard disks. For the master and slave jumpers, please refer to the hard disk’s
installation descriptions and the hard disk jumper settings.
You can select <AUTO> under the <TYPE> and <MODE> fields. This will enable auto detection of your
IDE drives during bootup. This will allow you to change your hard drives (with the power off) and then
power on without having to reconfigure your hard drive type. If you use older hard disk drives, which do not
support this feature, then you must configure the hard disk drive in the standard method as described
above by the <USER> option.

Please set as “Auto” if slave IDE device, which carries FAT16 partition, is used to boot up system.

~ Page 29 ~

Boot Sector Virus Protection

This option protects the boot sector and partition table of your hard disk against accidental modifications. Any
attempt to write to them will cause the system to halt and display a warning message. If this occurs, you can
either allow the operation to continue or use a bootable virus-free floppy disk to reboot and investigate your
system. The default setting is <

Disabled>. This setting is recommended because it conflicts with new operating

systems. Installation of new operating systems requires that you disable this to prevent write errors.

5-3. ADVANCED CMOS SETUP

The <Advanced CMOS Setup> option consists of configuration entries that allow you to improve your
system performance, or let you set up some system features according to your preference. Some entries
here are required by the CPU board’s design to remain in their default settings.

Floppy Access Control

This option determines the floppy access method, which can be either read only or normal (read/write).
When it is set, the data in the floppy is being read instead of being written.” Normal” allows the floppy to be
read or written.

HDD Access Control

This option determines the hard disk access method, which can be either read only or normal (read/write).
When it is set to read only, the data in the hard disk is being read instead of being written.” Normal” allows
the floppy to be read or written.

Available options: Disabled, Enabled

S.M.A.R.T for hard Disks

S.M.A.R.T is abbreviation of Self-Monitoring Analysis and Reporting Technology. It is reliable and
precautious technology. When Hard Disk is in disorder, it prevents Hard Disk from the loss of data.

BootUp Num-Lock

This item is used to activate the Num-Lock function upon system boot. If the setting is on, after a boot, the
Num-Lock light is lit, and the user can automatically use the number keys.

Floppy Drive Swap

The option reverses the drive letter assignments of your floppy disk drives in the Swap A, B setting,
otherwise you leave the setting to

Disabled (No Swap). This works separately from the BIOS Features and

floppy disk swap feature. It is functionally the same as physically interchanging the connectors of the
floppy disk drives. When <

Enabled>, the BIOS swaps the floppy drive assignments so that Drive A

becomes Drive B, and Drive B becomes Drive A under DOS.

Floppy Drive Seek

If the <Floppy Drive Seek> item is set to Enabled, the BIOS will seek the floppy <A> drive one time upon

bootup.

PS/2 Mouse Support

The setting of Enabled allows the system to detect a PS/2 mouse on bootup. If it is detected, IRQ12 will

be used for the PS/2 mouse. IRQ 12 will be reserved for expansion cards if a PS/2 mouse is not detected.

Disabled will reserve IRQ12 for expansion cards and therefore the PS/2 mouse will not function.

Typematic Rate

This item specifies the speed at which a keyboard keystroke is repeated.

System Keyboard

The setting of <Absent> allows the system to boot without a keyboard attached to the computer, while the

setting of <Present> is in the contrary.
Primary Display
The setting of

<Absent> allows the system to boot without a Primary Display attached to the computer,

while the setting of <Present> is in the contrary.

Password Check

This option enables password checking every time the computer is powered on or every time the BIOS
Setup is executed. If
turned on. If

Setup is chosen, the password prompt appears if the BIOS are executed.

Always is chosen, a user password prompt appears every time the computer is

Boot to OS/2 >64MB

When using the OS/2 operating system with DRAM of greater than 64MB installed, you need to Enabled

this option; otherwise leave this on the setup default of

Disabled.

Wait for ‘F1’ If Error

AMIBIOS POST error messages are followed by:

Press <F1> to continue

If this option is set to

Disabled, the AMIBIOS does not wait for you to press the <F1> key after an error

message.

Hit ‘DEL’ Message Display

Set this option to Disabled to prevent the following message:

Hit ‘DEL’ if you want to run setup

It will prevent the message from appearing on the first BIOS screen when the computer boots.

Internal Cache

This option specifies the caching algorithm used for the L1 internal cache memory. The settings are:

Setting Description

Disabled Neither L1 internal cache memory on the CPU or

L2 secondary cache memory is enabled.

PCI VGA Palette Snoop

This item is for BIOS to snoop the appearance of VGA palette, and modify it when it is necessary.

DMA & IRQ

These options specify the bus that the named IRQs/DMAs lines are used on. These options allow you to
specify IRQs/DMAs for use by legacy ISA adapter cards. These options determine if the BIOS should
remove an IRQ/DMA from the pool of availability of IRQs/DMAs passed to the BIOS configurable devices.
If more IRQs/DMAs must be removed from the pool, the end user can use these PCI/PnP Setup options to
remove the IRQ/DMA by assigning the option to the ISA/EISA setting. The onboard I/O is configurable
with BIOS.

Reserved Memory Size

This option specifies the size of the memory area reserved for legacy ISA adapter cards.

Reserved Memory Address

This option specifies the beginning address (in hex) of the reserved memory area. The specified ROM
memory area is reserved for use by legacy ISA adapter cards.
