WDT Function
The Watchdog Timer of motherboard consists of 8-bit programmable time-out
counter and a control and status register.
WDT Controller Register
There are two PNP I/O port addresses that can be used to configure WDT.
2Eh: EFIR (Extended Function Index Register, for identifying CR index number)
2Fh: EFDR (Extended Function Data Register, for accessing desired CR)
WDT Control Mode Register
The working algorithm of the WDT function can be simply described as a counting
process. The Time-Out Interval can be set through software programming. The
availability of the time-out interval settings by software or hardware varies from
boards to boards.
WADE-8075 allows users to control WDT through dynamic software programming.
The WDT starts counting when it is activated. It sends out a signal to system reset or
to non-maskable interrupt (NMI), when time-out interval ends. To prevent the
time-out interval from running out, a re-trigger signal will need to be sent before the
counting reaches its end. This action will restart the counting process. A well-written
WDT program should keep the counting process running under normal condition.
WDT should never generate a system reset or NMI signal unless the system runs into
troubles.
WADE-8075 / WADE-8076 User’s Manual

System Installation
The related Control Registers of WDT are all included in the following sample
program that is written in C language. User can fill a non-zero value into the
Time-out Value Register to enable/refresh WDT. System will be reset after the
Time-out Value to be counted down to zero. Or user can directly fill a zero value into
Time-out Value Register to disable WDT immediately. To ensure a successful
accessing to the content of desired Control Register, the sequence of following
program codes should be step-by-step run again when each register is accessed.
Additionally, there are maximum 2 seconds of counting tolerance that should be
considered into user’ application program. For more information about WDT, please
refer to Winbond W83627UHG data sheet.
There are two PNP I/O port addresses that can be used to configure WDT,
1) 0x2E:EFIR (Extended Function Index Register, for identifying CR index number)
2) 0x2F:EFDR (Extended Function Data Register, for accessing desired CR)
WDT Control Command Example
// Enter Extended Function Mode
outp(0x002E, 0x87);
outp(0x002E, 0x87);
// Enable Pin 77 as WDTO#
// Select Logic Device 8
outp(0x002E, 0x07);

// Select Count Mode
outp(0x002E, 0xF5);
outp(0x002F, (inp(0x002F) & 0xF7) | ( Count-mode Register & 0x08));
// Specify Time-out Value
outp(0x002E, 0xF6);
outp(0x002F, Time-out Value Register );
// Disable WDT reset by keyboard/mouse interrupts
outp(0x002E, 0xF7);
outp(0x002F, 0x00);
// Exit Extended Function Mode
outp(0x002E, 0xAA);

GPIO
The motherboard provides 16 input / output ports that can be individually
configured to perform a simple basic I/O function.
GPIO Pin Assignment
The WADE-8075 provides 16 input/output ports that can be individually configured
to perform a simple basic I/O function. Users can configure each individual port to
become an input or output port by programming register bit of I/O Selection. To
invert port value, the setting of Inversion Register has to be made. Port values can be
set to read or write through Data Register.
The GPIO port is located on J15 & J16 shown as follows. Please note: DO NOT
SHORT-CIRCUIT PIN 9 AND 10 OF J15 & J16!
The control for the GPIO signals is handled through a separate 2-byte I/O space.

BIOS Setup Information
WADE-8075 uses AMI BIOS structure stored in Flash ROM. These BIOS has a built-in
Setup program that allows users to modify the basic system configuration easily. This
type of information is stored in CMOS RAM so that it is retained during power-off
periods. When system is turned on, WADE-8075 communicates with peripheral
devices and checks its hardware resources against the configuration information
stored in the CMOS memory. If any error is detected, or the CMOS parameters need
to be initially defined, the diagnostic program will prompt the user to enter the
SETUP program. Some errors are significant enough to abort the start up.

BIOS Setup Information
Bootup Num-Lock State
This setting is to set the Num Lock status when the system is powered on. Setting to
[On] will turn on the Num Lock key when the system is powered on. Setting to [Off]
will allow users to use the arrow keys on the numeric keypad.
Choices: On, Off.
Quiet Boot
This BIOS feature determines if the BIOS should hide the normal POST messages
with the motherboard or system manufacturer's full-screen logo. When it is enabled,
the BIOS will display the full-screen logo during the boot-up sequence, hiding
normal POST messages.
When it is disabled, the BIOS will display the normal POST messages, instead of the
full-screen logo.
Please note that enabling this BIOS feature often adds 2-3 seconds of delay to the
booting sequence. This delay ensures that the logo is displayed for a sufficient
amount of time. Therefore, it is recommended that you disable this BIOS feature for a
faster boot-up time.
Choices: Disabled, Enabled.
Fast Boot
Enabling this setting will cause the BIOS power-on self test routine to skip some of its
tests during boot up for faster system boot.
Choices: Disabled, Enabled.
GateA20 Active
Choices: Upon Request, Always.
Option ROM Messages
This item is used to determine the display mode when an optional ROM is initialized
during POST. When set to [Force BIOS], the display mode used by AMI BIOS is used.
Select [Keep Current] if you want to use the display mode of optional ROM.
Choices: Force BIOS, Keep Current.

BIOS Setup Information
Interrupt 19 Capture
Interrupt 19 is the software interrupt that handles the boot disk function. When
enabled, this BIOS feature allows the ROM BIOS of these host adaptors to "capture"
Interrupt 19 during the boot process so that drives attached to these adaptors can
function as bootable disks. In addition, it allows you to gain access to the host
adaptor's ROM setup utility, if one is available.
When disabled, the ROM BIOS of these host adaptors will not be able to "capture"
Interrupt 19. Therefore, you will not be able to boot operating systems from any
bootable disks attached to these host adaptors. Nor will you be able to gain access to
their ROM setup utilities.
Choices: Disabled, Enabled.

Troubleshooting
This chapter provides a few useful tips to quickly get WADE-8075 running with
success. As basic hardware installation has been addressed in Chapter 2, this chapter
will primarily focus on system integration issues, in terms of BIOS setting, and OS
diagnostics.

BIOS Setting
It is assumed that users have correctly adopted modules and connected all the
devices cables required before turning on ATX power. CPU, CPU Fan, 204-pin DDR3
SDRAM, keyboard, mouse, floppy drive, SATA hard disk , device power cables, ATX
accessories are good examples that deserve attention. With no assurance of properly
and correctly accommodating these modules and devices, it is very possible to
encounter system failures that result in malfunction of any device.
To make sure that you have a successful start with WADE-8075, it is recommended,
when going with the boot-up sequence, to hit “DEL” key and enter the BIOS setup
menu to tune up a stable BIOS configuration so that you can wake up your system far
well.
Loading the default optimal setting
When prompted with the main setup menu, please scroll down to “Restore
Defaults”, press “Enter” and “Y” to load in default optimal BIOS setup. This will
force your BIOS setting back to the initial factory configuration. It is recommended to
do this so you can be sure the system is running with the BIOS setting that Portwell
has highly endorsed. As a matter of fact, users can load the default BIOS setting any
time when system appears to be unstable in boot up sequence.
Improper disable operation
There are too many occasions where users disable a certain device/feature in one
application through BIOS setting. These variables may not be set back to the original
values when needed. These devices/features will certainly fail to be detected.
When the above conditions happen, it is strongly recommended to check the BIOS
settings. Make sure certain items are set as they should be. These include the COM1/
COM2 ports, USB ports, external cache, on-board VGA and Ethernet.
It is also very common that users would like to disable a certain device/port to
release IRQ resource. A few good examples are
Disable COM1 serial port to release IRQ #4
Disable COM2 serial port to release IRQ #3
Etc…
