1. Introduction

Thank you for choosing NOVA-7810. NOVA-7810 is an Intel Mobile
Processor CPU with Multimedia & LAN Ethernet Embedded Little Board
equipped with low power Intel Mobile Processor CPU with the Intel
advanced chipset 815E. This product is designed for system manufacturers,
integrators, or VARs who want to build a low power consumption system.

NOVA-7810 provides on-chip VGA of up to 1600 x 1200 resolution and LCD
of up to 1024 x 768 resolution.

An advanced high performance super I/O chip—W83627 and NS87366 is
used in the NOVA-7810 board, which provides four UARTs1 compatible with
NS16C550. The parallel port and FDD interface are compatible with IBM
PC/AT architecture.

NOVA-7810 has one Fast Ethernet Multifunction PCI Controller as a LAN
controller fully integrated 10BASE-T/100BASE-TX LAN solution with high
performance networking functions and low power features.

3.18 Digital I/O

One of the characteristics of digital circuit is fast response to high or
low signal. This kind of response is highly needed for industrial
operating environment. NOVA-7810 is designed with 4-bit digital
inputs and 4-bit digital outputs to maintain a quality performance in
such environment.

Digital Input and Output are control signals used to control external
devices that needs On/Off circuit or TTL devices. We provide "BIOS
Call" for DIO's reading.

This chapter discusses the Setup program built into the BIOS, which
allows users to configure the system. This configuration is then
stored in battery-backed CMOS RAM so that Setup information is
retained when the power is off.

4.2 Starting Setup

The BIOS is immediately active when you turn on the computer.
When BIOS is activated, the Setup program can be entered in one of
two ways:

1.

By pressing <Del> immediately after switching the system on,
or

2. By pressing the <Del> key when the following message appears
briefly at the bottom of the screen during the POST (Power On
Self-Test).

Press DEL to run SETUP.

Primary/Secondary Master/Slave LBA Mode

LBA (Logical Block Addressing) is a new IDE HDD access method
developed to overcome the 528-megabyte capacity bottleneck. If
your IDE hard disk capacity is greater than 528MB, AMIBIOS can
enable this LBA mode feature. This option is only for Primary Master
IDE LBA mode.

Primary/Secondary Master/Slave Block Mode

If your hard disk drive supports IDE block transfer mode, enable this
option for a faster IDE hard disk drive transfer rate. This option is
only for Primary Master Block mode.

Primary/Secondary Master/Slave PIO Mode

This option enables Primary Master IDE PIO mode on the IDE, which
can set proper cycle timings. The cycle timing between the IDE PIO
mode value and IDE cycle timing is shown below:
Mode 0 -> Timing (600ns) Mode 1 -> Timing (383ns)
Mode 2 -> Timing (240ns) Mode 3 -> Timing (180ns)
Mode 4 -> Timing (120ns) Mode 5 -> Timing (60ns)

28

Primary/Secondary Master/Slave 32Bit Mode

This option enables Primary Master IDE 32-bit data transfers on the
IDE data port. When disabled, 16-bit data transfer will be used by
the BIOS. 32-bit data transfers can only be enabled if IDE prefetch
mode is also enabled.

Boot Sector Virus Protection

When this option is enabled, AMIBIOS issues a warning when any
program or virus issues a Disk Format command or attempts to write
to the boot sector of the hard disk drive. The settings are Disabled,
Enabled.

Base/Extd Memory

Displays the amount of conventional/extended memory detected
during boot up.

should remove an IRQ from all available IRQs. The available IRQ
pool is determined by reading the ESCD NVRAM and is passed to
devices configurable by the system BIOS. If more IRQs must be
removed from the pool, users can reserve the IRQ by assigning an
ISA/EISA setting to it. Onboard I/O is configured by AMIBIOS. All

-

Bi-Dir: Use this setting to support bi-directional transfers on the
parallel port.

-

EPP: The parallel port can be used with devices that adhere to the
Enhanced Parallel Port (EPP) specification. EPP uses the existing
parallel port signals to provide asymmetric bi-directional data
transfer driven by the host device.

-

ECP: The parallel port can be used with devices that adhere to the
Extended Capabilities Port (ECP) specification. ECP uses DMA
protocol to achieve data transfer rates up to 2.5 Megabits per
second. ECP provides symmetric bi-directional communication.

Parallel Port IRQ

This option specifies the IRQ used by the parallel port. The settings
are Auto, (IRQ) 5, or (IRQ) 7.

Appendix A: Watchdog Timer

The Watchdog Timer is provided to ensure that standalone systems can always
recover from CPU crash caused by external EMI or a software bug. When the
CPU is not functioning normally, a hardware reset (cold boot) will be performed to
bring the system to a normal state.

A BIOS function call (INT 15H) is used to control the Watchdog Timer:

INT 15H:

AH – 6FH

Sub-function:

AL – 2: Set the Watchdog Timer period
BL : Time-out value (the time unit—second,

is dependent on Watchdog Timer unit
(selected in BIOS setup).

You have to call sub-function 2 to set the time-out period of Watchdog Timer first.
If the time-out value is not zero, Watchdog Timer will begin counting down.
When the timer value reaches zero, the system will reset. To ensure this reset
condition does not occur, Watchdog Timer must be periodically refreshed by
calling sub-function 2. However the Watchdog timer will be disabled if you set
the time-out value to be zero.

A tolerance of at least 10% must be maintained to avoid unknown routines within
the operating system (DOS), such as disk I/O that can be very time-consuming.

Note: When exiting a program, it is necessary to disable the Watchdog Timer.
Otherwise, the system will reset.

Example program:

; INITIAL TIMER PERIOD COUNTER
;

W_LOOP:

MOV AX, 6F02H ;setting the time-out value
MOV BL, 30 ;time-out value is 48 seconds

INT 15H
;
; ADD YOUR APPLICATION PROGRAM HERE
;
CMP EXIT_AP, 1 ;is your application over?
JNE W_LOOP ;No, restart your application

MOV AX, 6F02H ;disable Watchdog Timer
MOV BL, 0 ;
INT 15H
;
; EXIT

43

Appendix B: Digital I/O

One of the characteristics of digital circuit is fast response to high or low signal.
This kind of response is highly needed for harsh and critical industrial operating
environment. NOVA-7810 is designed with 4-bit digital inputs and 4-bit digital
outputs to ensure a quality performance in such operating environment.

Digital Input and Output are control signals generally. Use these signals to
control external devices that needs On/Off circuit or TTL devices. You can read or
write data to the selected address to enable digital I/O function.

A BIOS function call (INT 15H) is used to control Watchdog Timer:

INT 15H:

AH – 6FH

Sub-function:

AL – 8 : Set the Digital port is INPUT
AL : Digital I/O input value

Example program:

MOV AX, 6F08H ;setting the Digital port is input
INT 15H ;

AL low byte = value

AH – 6FH

Sub-function:

AL – 9: Set the Digital port is OUTPUT
BL : Digital I/O output value

Example program:

MOV AX, 6F09H ;setting the Digital port is output
MOV BL, 09H ;Digital value is 09H
INT 15H ;

Digital Output is 1001b
