2.2 Unpacking
The ROCKY-538TXV Single Board Computer contains sensitive electronic
components that can be easily damaged by static electricity.
In this section, we describe the precautions that you should take while unpacking,
as well as during installation. It is very important that the instructions be followed
correctly, to avoid static damage, not to mention successfully install the board for
operation.
The system board should be done on a grounded anti-static mat. The
operator should be wearing an anti-static wristband, grounded at the same
point as the anti-static mat.
Inspect the cardboard carton for obvious damage. Shipping and handling
may cause damage to your board. Be sure there are no shipping and
handing damages on the board before you continue.
After opening the cardboard carton, exact the system board and place it only
on a grounded anti-static surface component side up.
Again inspect the board for damage. Press down on all the socketed IC's to
make sure that they are properly seated. Do this only with the board place
on a firm flat surface.
Note : DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED.
You are now ready to install your ROCKY-538TXV Single Board Computer.

AWARD BIOS setup program is designed to provide maximum flexibility in
configuring the system by offering various options which may be selected to meet
end-user demands. This chapter is written to assist you in the proper usage of
these features.
4.1 Getting Start
When powering on the system, the BIOS will enter the Power-On-Self-Test
routines. These routines will be executed for system test, initialization and system
configuration verification. After the POST routines are completed, the following
message appears :
" Hit DEL if you want to run SETUP"
To access AWARD PCI/ISA BIOS Setup program, press <Del> key. The following
screen will be displayed at this time.
When you choose Load BIOS Defaults , the system will load minimized settings
for Troubleshooting. The performance should be very poor when you use this
setting.
When you select Load Setup Defaults , the system will load optimized defaults
for regular use. Choosing this setting, will modify all applicable settings.
22
4.2 Standard CMOS Setup

unstable.
Auto Configuration : Enable or Disable
When you are using 60nS general type DRAM, please enable this setting so
as to get optimal timings.
SDRAM Speculative Read : Enable or Disable
When you enable this option, the CPU will send predict commands to the
SDRAM, if a miss happens, the CPU will cancel this command. As some OS
under certain situations have problem enabling this feature, it is normally set
to disable.
Memory Hole at 15M-16M : Enable or Disable
This setting reserve 15MB to 16MB memory address space for ISA expansion
cards that specifically needs this setting. Memory from 15MB and up will be
unavailable to the system because expansion cards can only access memory
up to 16MB.
CPU Warning Temperature : Disable,50 ..
There is a LM75 temperature sensor under the bottom of CPU. Setting CPU
Warning Temperature to a certain limit which will help customer in securing
the system as not to burn out resulted from a fan failed or other related
accidents.
Hardware Monitoring :
In this option, customer could see the working status of this board for
Current CPU Temperature, Current System Temperature, Current
CPUFAN1 Speed, Current CPUFAN2 Speed, Vcore voltage, Vio
voltage,+5V,-5V,+12V,and –12V status.

4.5 Integrated Peripherals
This part of setup for Multi-I/O Chip (W83977F ). These options are used to
change the ChipSet‘s registers. Please be careful while making any changes to
default setting so as to meet your application needs. The only special point that
you must pay attention to in this menu page is the Onboard Serial Port2. If you
are using the IrDA port, you will have to set this port accordingly.

4.6 Power Management Setup
Power Management Setup help users in modifying ROCKY-538TXV board‘s
“green” function. These features could shut down video display and hard disk in
order to save energy. Please refer to the sample caption below for power
management setup screen:
Power Management : Disable, Max Saving, Min Saving, or User
Defined
Max Saving puts the system into power saving mode after a brief period of
inactivity. Min Saving is almost the same as Max Saving except that the
inactivity period is longer. User Defined allows you to set power saving
options according to your needs.
Note : Advanced Power Management(APM) have to be installed to keep the system
time updated when the computer enters suspend mode activated by the Power
Management. Under DOS environment, you need to add
DEVICE=C:\DOS\POWER.EXE in your CONFIG.SYS on the other hand under
Windows 3.x and Windows 95,you have to install Windows with APM feature. A
battery and power cord icon labeled “Power” Will appear in the “Control Panel”
27
4.7 PNP/PCI Configuration
The PNP/PCI Configuration help users to set ROCKY-538TXV board’s “PCI”
function. All PCI bus slots on the system use INTA#, thus all installed PCI slots
must be set to this value.
PNP OS Installed : Yes or No
When PNP OS is installed, interrupts may be reassigned by the OS when the
setting is Yes. When a non-PNP OS is installed or to prevent reassigning of
interrupt settings, please set setting to No.

Appendix A. E2 Key™ Function
The ROCKY-538TXV provides an outstanding E2KEY™ function for system
integrator. Based on the E
2
KEY™ you are free to store ID Code, Pass Word, or
Critical Data in the 1Kbit EEPROM. As the EEPROM is nonvolatile memory, you
don’t have to worry about losing important data.
Basically the E
2
KEY™ is based on a 1Kbit EEPROM which is configured to 64
words(from 0 to 63). You could access (read or write) each word at any time.
When you need to use E
2
KEY™ you should find the utility inside of the package.
The software utility will include the following four files,
README.DOC
E2KEY.OBJ
EKEYDEMO.C
EKEYDEMO.EXE.
The E2KEY.OBJ provides two library function for user to integrate their application
with E
2
KEY™ function. These library (read_e2key and write_e2key) are
written and compiled in C format. Please refer to the following statement and you
will know how to implement it.
unsigned int read_e2key(unsigned int address)
/* This function will return the E
2
KEY™’s data at address. The address range
is from 0 to 63. Return data is one word, 16 bits */
void write_e2key(unsigned int address,unsigned data)
/* This function will write the given data to E
2
KEY™ at address. The address
range is from 0 to 63. The data value is from 0 to 0xffff. */
A quick and easy way to learn to use the function is to first review EKEYDEMO.C
code included.
Please note the E
2
KEY™ function is only available if the parallel port is working. In
other words, you should enable ROCKY-538TXV’s parallel port, otherwise will this
function will be not working.

Appendix B. Watch-Dog Timer
The Watch-Dog Timer is provided to ensure that standalone systems can always
recover from catastrophic conditions that caused the CPU to crash. This condition
may have occurred by external EMI or a software bug. When the CPU stops
working correctly, hardware on the board will either perform a hardware reset
(cold boot) or a non-maskable interrupt (NMI) to bring the system back to a
known state.
The Watch-Dog Timer is controlled by two I/O ports.
443 (hex) Read Enable the refresh the Watch-Dog Timer.
043 (hex) Read Disable the Watch-Dog Timer.
To enable the Watch-Dog Timer, a read from I/O port 443H must be performed.
This will enable and activate the countdown timer which will eventually time out
and either reset the CPU or cause an NMI depending on the setting of JP13. To
ensure that this reset condition does not occur, the Watch-Dog Timer must be
periodically refreshed by reading the same I/O port 433H. This must be done
within the time out period that is selected by jumper group JP15.
A tolerance of at least 30% must be maintained to avoid unknown routines within
the operating system (DOS), such as disk I/O that can be very time consuming.
Therefore if the time out period has been set to 10 seconds, the I/O port 443H
must be read within 7 seconds.
Note: While exiting a program, it is necessary to disable the Watch-Dog Timer,
otherwise the system will reset.
