settings are best-case values which will provide the best
performance. Whenever your CMOS RAM is damaged, this
Optimal settings will be loaded automatically.
45
4.11 Auto Configuration with Fail Save Settings
This option lets you load the Fail Safe default settings when
something happens to your computer so that it cannot boot
normally. These settings are not the most optimal settings but are
the most stable settings.
4.12 Save Settings and Exit
Select this option when you finish setting all the parameters and
want to save them into the CMOS. Just simply press <Enter> key
and all the configuration changes will be saved.
46
4.13 Exit Without Saving
Select this option if you want to exit the Setup without saving the
changes that you made. Just simply press <Enter> key and you
will exit the BIOS SETUP without saving the changes.

E2 Key™ Function
47
The POS-566/566L provides an outstanding E2KEY™ function for
system integrator. Based on the E2KEY™, you can free to store
the ID Code, Password or Critical Data in the 1Kbit EEPROM.
Because the EEPROM is nonvolatile memory, you don’t have to
worry for losing very important data.
Basically the E2KEY™ 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 start to use the E2KEY™ you should have the utility in
the package. The software utility will include four files as follows,
README.DOC
E2KEY.OBJ
EKEYDEMO.C
EKEYDEMO.EXE.
The E2KEY.OBJ provides two library functions for user to integrate
their application with E2KEY™ function. These library
(read_e2key and write_e2key) are written and compiled in C
language. Please check the following statement, then you will
know how to implement it easily.
unsigned int read_e2key(unsigned int address)
/* This function will return the E2KEY™’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 E2KEY™ at certain
address. The address range is from 0 to 63. The data value is from
0 to 0xffff. */
To easily start to use the function, please refer to the included
EKEYDEMO.C code at first.
Please note that the E2KEY™ function is based on the working of
48
parallel port. So you should enable the POS-566/566L’s parallel
port, otherwise it will not work.

Appendix C. Watch-Dog Timer
51
The WatchDog Timer is provided to ensure that standalone systems
can always recover from catastrophic conditions that cause 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 NonMaskable Interrupt (NMI) to bring the system back to a known state.
Two I/O ports control the WatchDog Timer :.
443
(hex)
Read Enable to refresh the WatchDog
Timer.
843
(hex)
Read Disable the WatchDog Timer.
To enable the WatchDog 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 a NMI,
depending on the setting of JP11. To ensure that this reset condition
does not occur, the WatchDog 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 JP16.
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: when exiting a program it is necessary to disable the
WatchDog Timer, otherwise the system will reset.
Appendix D. Flat Panel Connection Module
52
The FP24-01 connection module is installed on the POS-566/566L as
a standard product. The FP24-01 converts POS-566/566L’s on board
50pin LCD interface signal to the 44-pin and 41pin (Hirose DF9-41P1V) LCD connectors. The 44-pin or 41-pin connector will only support
24-bit flat panel.
