Chapter 3 BIOS Setup
This chapter describes the BIOS setup.
Overview
BIOS are a program located on a Flash memory chip on a circuit board. It is used
to initialize and set up the I/O peripherals and interface cards of the system, which
includes time, date, hard disk drive, the ISA bus and connected devices such as
the video display, diskette drive, and the keyboard. This program will not be lost
when you turn off the system.
The BIOS provides a menu-driven interface to the console subsystem. The console
subsystem conta i n s s p ec i a l s o f tw a r e, called firm wa r e tha t i n ter a c ts d irectly 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 b y the
manufacturer.
All the changes you make will be saved in the system RAM and will not be lost after
power-off.
When you start the system, the BIOS will perform a self-diagnostics test called Power
On Self Test (POST) for all the attached devices, accessories, and the system. Press
the [Del] key to enter the BIOS Setup program, and then the main menu will show
on the screen.
Note: Change the parameters when you fully understand their functions and
subsequence.

18
FabIATech Corporation
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 boot up. 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.
Video
This option selects the type of adapter used for the primary system monitor that
must match your video display card and monitor. Although secondary monitors
are suppor ted, you do not have to select the type in Setup.
You have two ways to boot up the system:
When VGA set as primary an d monochrome set as secondary, the selection of the
video type is “ VGA Mode”.
When monochrome set as primary and VGA set as secondary, the selection of the
video type is “Monochrome Mode”.
Error Halt
This option determines whether the computer will stop if an error is detected during
power up.
No errors The system boot will not be stopped for any error that may be detected.
All errors Whenever the BIOS detect a non-fatal error the system will be stopped
and you will be prompted.

other errors.
all other errors.
Memory
This option is display-only which is determined by POST (Power On Self Test) of the
.
BIOS
Base Memory
The POST of the BIOS will determine the amount of base (or conventional) memory
19
FabIATech Corporation
installed in the system. The value of t he base memory is typically 512K for systems
with 512K memories installed on the motherboard, or 640K for systems with 640K or
more memory installed on the motherboard.
Extended Memory
The BIOS determines how much extended memory is present during the POST. This is
the amount of memory located above 1MB in the CPU’s memory address map.
Other Memory
This refers to the memory located in the 640K to 1024K-address space. This is memory
that can be used for different applications. DOS uses this area to load dev ice drivers
to keep as much base memory free for application programs. Most use for this area
is Shadow RAM.
Total Memory
System total memory is the sum of basic memory, extended memory, and other
memory.

Peripheral Setup
This section describes the function of peripheral features.
IDE HDD Block Mode
This option allows your hard disk controller to use the fast block mode to transfer
data to and from your hard disk drive (HDD).
IDE PIO
IDE hard drive controllers can support up to two separate hard drives. These drives
have a master/slave relationship, which is determined by t he cabling configuration
used to attach them to the controller. Your system supports one IDE controller – a
primary and a secondary – so you have the ability to install up to four separate hard
disks.
PIO means Programmed Input/Output. Rather than have the BIOS issue a series of
commands to affect a transfer to or from the disk drive, PIO allows the BIOS to tell
the controller what it wants and then let the controller and the CPU perform the
complete task by them. This is simpler and more efficient (and faster). Your system
supports five modes, numbered from 0 to 4, which primarily differ in timing. When
Auto is selected, the BIOS will select the best available mode.

Watchdog Timer
This section describes how to use the Watchdog Timer, including disabled, enabled,
and trigger functio ns.
The FX5401 is equipped with a programmable time-out period watchdog timer.
You can use your own program to enable the watchdog timer. Once you have
enabled the watchdog timer, the program should tri gger the I/O every time before
the timer time s out. If your program fails to trigger or disable this timer before it
times out, e.g. because of a system hang-up, it will generate a reset signal to reset
the system. The time-out period can be programmed to be set from 1 to 255
seconds or minutes.

Watchdog Timer Setting
The watchdog timer is a circuit that may be used from your program software to
detect system crashes or hang-ups. LED1 on this CPU board is the watchdog tim er
indicator, which is located at the upper-left corner above the USB connector.
Whenever the watchdog timer is enable d, the LED will blink to ind icate that the
timer is counting. The watchdog tim er is automatically disab led after reset.
Once you have enabled the watchdog timer, your program must trigger the
watchdog timer every time before it times out. After you trigger the wa tchdog
timer, it will be set to non- zero value to watchdog counte r and start to c ount down
again. If your program fails to trigger the watchdog timer before time-out, it will
generate a reset pulse to rese t the system.
The factor of the watchdog timer time-out constant is appr oximately 1 seconds.
The perio d for the watchdog timer time-out is between 1 to FF timer factors.
If you want to reset your system when watchdog times out, the following table
listed the relation of timer factors between time-out periods.

Watchdog Timer Enabled
To enable the watchdog timer, you have to output a byte of timer factor to the
++
watchdog. The following is a Turbo C
program, which demonstrates how to enable
the watchdo g timer and set the time-ou t period at 6 seconds.
#include “stdio.H”
#include “WDLIB.H”
main( )
{
char WD_TIME=ox6;
InitWD(equWdUnitS);
printf ( “Enable watchdog”);
//Trigger watchdog Timer Output is 6 seconds
EnWD(WD_TIME);
}
Watchdog Timer Trigger
After you enable the watchdog timer, your program must write the same factor as
enabling to the watchdog register at least once every time-out period to its
previous se tting. You can change the time-out period by writing another timer
factor to th e watchdog register at any time, and you must trigger the w atchdog
++
before the new time-out period in the next trigger. Below is a Turbo C
program,
which demonstrates ho w to trigger the watchdog timer:
#include “stdio.H”
#include “WDLIB.H”
main( )
{
char WD_TIME=ox6;
InitWD(equWdUnitS);
printf ( “Enable watchdog”);
//Trigger watchdog Timer Output is 6 seconds

DMA Channel Map
The equivalent of two 8237A DMA controllers are implemented in the FX5401 board.
Each controller is a four-channel DMA device that will generate the memory
addresses and control signals necessary to transfer information directly between a
peripheral device and memory. This allows hig h s p ee di ng i nf o rm at io n transfer with less
CPU intervention. The two DMA controllers are internally cascaded to provide four
DMA channe ls for transf ers to 8-bit peripherals (DMA1) and three channels for
transfers to 16-bit peripherals (DMA2). DMA2 channel 0 provides the cascade
interconn ection betwee n the two DMA devices, thereby maintaining IBM PC/AT
compatibility.

Serial Ports
The ACEs (Asynchronous Communication Elements ACE1 to ACE2) are used to
convert parallel data to a serial format on the transmit side and convert serial data
to parallel on the receiver side. The serial format, in order of transmission and
reception, is a start bit, followed by five to ei ght data bits, a parity bit (if
programmed) and one, one and half (five-bit format only) or two stop bits. The
ACEs are capable of handling divisors of 1 to 65535, and produce a 16x clock for
driving the internal transmitter logic.
Provisions are also included to use this 16x clock to drive the receiver logic. Also
included in the ACE a completed MODEM control capability, and a processor
interrupt system that may be software tailored to the computing time required to
handle the communications link.

Printer Interface Logic
The parallel portion of the SMC37C669 makes the attachment of various devices
that accept eight bits of parallel data at standard TTL level.
Data Swapper
The system microprocessor can read the contents of the printer’s Data Latch
through the Data Swapper by reading the Data Swapper address
Printer Status Buffer
The system microprocessor can read the printer status by reading the address of
the Printer Status Buffer. The bit definitions are described below:
12345670
XXX
-ERROR
SLCT
PE
-ACK
-BUSY
NOTE: X represents not used.

Bit 7: This signal may become active during data entry, when the printer is off-line
during printing, or when the p rint head is changing position or in an error
state. When Bit 7 is active, the printer is busy and cannot accept data.
Bit 6: This bit re presents the c urrent state of the printer ’s ACK signal. A 0 means the
printer has received the character and is ready to accept another.
Normally, this signal will be active for approximately 5 microseconds before
rece iving a BUSY message stops.
Bit 5: A 1 means the printer has detected the en d of the paper.
Bit 4: A 1 means the printe r is selected.
Bit 3: A 0 means the printer has encountered an error condition.
Printer Control Latch & Printer Control Swapper
The system microprocessor can read the contents of the printer control latch by
reading the address of printer control swapper. Bit definitions are as follows:
XX
12345670
STROBE
AUTO FD XT
INIT
SLDC IN
IRQ ENABLE
DIR(write only)
NOTE: X represents not used.

Bit 5: Direction control bit. When logic 1, the output buffers in the parallel port
are disabled allowing data driven from external sources to be read; when
logic 0 they work as a printer port. This bit is write-only.
Bit 4: A 1 in this po sition allows an interrupt to occur when ACK changes from low
state to high state.
Bit 3: A 1 in this bit position selects the printer.
Bit 2: A 0 starts the prin ter (50 microseconds pulse, minimum).
Bit 1: A 1 causes the pri nter to line-feed after a line is printed.
Bit 0: A 0.5 microsecond minimum highly active pulse clocks data into the printer.
Valid data must be present for a minimum of 0.5 microseconds before and
after the strobe pulse.
