ATX Form Factor Motherboard
ATX is an evolution of the popular Baby-AT form-factor defined to address four major areas of
improvement over today’s predominant form factors: enhanced ease-of-use, better support for current
and future I/O and better support for current and future processor technology.
This motherboard is designed to fit into a standard ATX form factor chassis in that the outer
dimensions are 12" x 9.6" (30.48 cm x 24.38 cm). The location of I/O connectors, CPU socket, PCI
and ISA slots, and mounting holes are also strictly based on the ATX specification.
By simply rotating the board through 90 degrees (with respect to baby -AT form factor) within the
chassis, the end-user gains a great deal in ease-of-use and improved functionality.
•
•
•
•
•
•
•
With the processor relocated, all expansion slots can be full-length.
Since the processor is not located between or under the add-in cards, a processor upgrade
can now be performed without removing the installed cards.
The SIMM connectors can be relocated away from the expansion bays and slots, increasing
ease-of-use by giving easy access to the user for memory upgrades, and increasing the total
number of available full length slots.
The use of only one fan within the system reduces noise levels.
More I/O is integrated onto the baseboard, improving reliability and reducing the number
of cables.
Disk I/O connectors are located closer to the peripheral bays, reducing cable lengths. This
reduces the clutter in the chassis and allows the use of faster hard disk drives.
With increased ease of use, and a reduction in cable complexity, the technical support burden is
lowered.

errors are corrected by the chipset. Corrected bits of data from memory
are not written back to DRAM system memory. If Level I is selected, the
J25 External SMI software jumper on the Series 745 board is disabled.
Multibit errors are detected and reported as parity errors. Single-bit
errors are corrected by the chipset and are written back to DRAM
system memory.
If a soft (correctable) memory error occurs, writing the fixed data back
to DRAM system memory will resolve the problem. Most DRAM errors
are soft errors. If a hard (uncorrectable) error occurs, writing the fixed
data back to DRAM system memory does not solve the problem. In this
case, the second time the error occurs in the same location, a Parity Error
is reported, indicating an uncorrectable error. If ECCI is selected,
AMIBIOS automatically enables the System Management Interface
(SMI) is enabled. If you do not want to enable power management, set
the Power Management/APM option to Disabled and set all Power
Management Setup timeout options to Disabled. To enable power

PCI/PNP SETUP
The PCI/PnP Setup options are displayed by choosing the PCI/PnP Setup icon from
the WINBIOS Setup main menu. All PCI/PnP Setup options are described in this
section
Plug and Play Aware OS
Set this option to Yes if the operating system installed in the computer is Plug
and Play-aware. AMIBIOS only detects and enables PnP ISA adapter cards
that are required for system boot. The Windows 95 operating system detects
and enables all other PnP-aware adapter cards. Windows 95 is PnP-aware. Set
this option to No if the operating system (such as DOS, OS/2, Windows 3.x)
does not use PnP. You must set this option correctly or PnP-aware adapter
cards installed in your computer will not be configured properly. The settings
are No or Yes.
PCI Burst Mode
Set this option to Enabled to enable PCI burst mode. The settings are Disabled
or Enabled.
PCI Concurrency
Set this option to Enabled to enable PCI Concurrency mode. The settings are
Disabled or Enabled.
PCI Steamming
Set this option to Enabled to enable PCI Steamming mode. The settings are
Disabled or Enabled.
PCI Latency Timer (in PCI Clocks)
This option sets latency of all PCI devices on the PCI bus. The settings are in
units equal to PCI clocks. The settings are 32, 64, 96, 128, 160, 192, 224, or
248.
PCI VGA Palette Snoop
This option must be set to Enabled if any ISA adapter card installed in the
computer requires VGA palette snooping. The settings are Disabled or
Enabled.
Allocate IRQ To PCI VGA
Page 43
Motherboard Installation
Set this option to Yes to allocate an IRQ to the VGA device on the PCI bus. The settings are
Yes or No. The Optimal and Fail-Safe default settings are Yes.
PCI IDE Bus Master
Set this option to Enabled to specify that the IDE controller on the PCI bus has bus mastering
capability. The settings are Disabled or Enabled. The Optimal and Fail-Safe default
settings are Disabled.
Offboard PCI IDE Card
This option specifies if an offboard PCI IDE controller adapter card is used in
the computer. You must also specify the PCI expansion slot on the
motherboard where the offboard PCI IDE controller card is installed. If an
offboard PCI IDE controller is used, the onboard IDE controller on the
motherboard is automatically disabled. The settings are Disabled, Auto, Slot1,
Slot2, Slot3, or Slot4.
If Auto is selected, AMIBIOS automatically determines the correct setting for
this option. The Optimal and Fail-Safe default settings are Auto.
IRQ3-IRQ15
These options specify the bus that the named interrupt request lines (IRQs) are
used on. These options allow you to specify IRQs for use by legacy ISA
adapter cards.
These options determine if AMIBIOS should remove an IRQ from the pool of
available IRQs passed to BIOS configurable devices. The available IRQ pool is
determined by reading the ESCD NVRAM. If more IRQs must be removed
from the pool, the end user can use these PCI/PnP Setup options to remove the
IRQ by assigning the option to the ISA/EISA setting. Onboard I/O is
configurable by AMIBIOS. The IRQs used by onboard I/O are configured as
PCI/PnP.
The settings are PCI/PnP or ISA/EISA. The Optimal and Fail-Safe default
settings are PCI/PnP.
Reserved Memory Size
This option specifies the size of the memory area reserved for legacy ISA
adapter cards. The settings are Disabled, 16K, 32K, or 64K.
Page 44
Motherboard Installation
Reserved Memory Address
This option specifies the beginning address (in hex) of the reserved memory
area. The specified ROM memory area is reserved for use by legacy ISA
adapter cards.
The settings are C0000, C4000, C8000, CC000, D0000, D4000, D8000, or
DC000. The Optimal and Fail-Safe default settings are C0000.

PERIPHERAL SETUP
The WinBIOS Setup options described in this section are selected by choosing the
appropriate high-level icon from the WinBIOS Setup main menu.
The settings are Auto or Manual. When set to Auto, WinBIOS automatically
detects all the peripheral installed in the system and configures the onboard I/O
(serial ports, parallel ports, floppy controllers) automatically. All other
Peripheral Setup option settings are ignored. Any serial port, parallel port,
floppy controller on an adapter card in an expansion slot is configured before
onboard I/O. If the offboard serial ports are configured to specific starting I/O
ports via jumper settings, WinBIOS configures the onboard serial ports to
avoid conflicts. If Manual is selected, the setting chosen by the end user in
Peripheral Setup apply. WinBIOS reports any I/O conflicts after displaying the
BIOS Configuration Summary Screen, but only if Manual is chosen.
On-Board Floppy Controller (FDC)
This option enables the use of the floppy drive controller on the board. The
settings are Enabled or Disabled

SECTION 3
SECURITY
PASSWORD SUPPORT
WinBIOS Setup has an optional password feature. The system can be
configured so that all users must enter a password every time the system boots
or when WinBIOS Setup is executed.
You can enter a password by:
•
typing the password on the keyboard,
•
selecting each letter via the mouse.
Setting a password
The Password Check option is enabled in Advanced Setup by choosing either
Always (the password prompt appears every time the system is powered on) or
Setup (the password prompt appears only when WinBIOS Setup is run). The
password is stored in CMOS RAM.
Enter a 1-6 character password. The password does not appear on the screen
when typed. WinBIOS will ask you to retype the password. If you forget it,
you must drain CMOS RAM and reconfigure the system.
Changing a password
Select the Password icon from the Security section of the WinBIOS main
menu. Enter the password and press <Enter>. The screen does not display the
characters entered. After the new password is entered, retype the new
password as prompted and press <Enter>.
If the password confirmation is incorrect, an error message appears. If the new
password is entered without error, press <Esc> to return to the WinBIOS
Setup Main Menu. The password is stored in CMOS RAM after WinBIOS
Setup completes. The next time the system boots up you are prompted for the
password if the password function is present and is enabled.

ANTI-VIRUS
When the Anti-Virus is enabled from the Security section of the WinBIOS
Setup menu, WinBIOS 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 Enabled or Disabled. If Enabled is selected, the following
appears when a write is attempted to the boot sector. You may have to type N
several times to prevent the boot sector write.
Boot Sector Write!!!
Possible VIRUS: Continue (Y/N)? _
The following is displayed after any attempt to format any cylinder, head, or
sector of any hard disk drive via the BIOS INT 13h Hard Disk Drive Service:
Format!!!
Possible VIRUS: Continue (Y/N)? _
Formatting the Hard Disk Drive
You should not enable anti-virus protection when formatting a hard disk drive.
The DOS hard disk Format utility does not use INT 13h function AH = 05h to
format the hard disk. It only verifies the hard disk using the INT 13h Verify
function (AH = 04h). The virus warning message is not displayed during DOS
hard disk drive formatting.
If the anti-virus feature is enabled, a virus warning message will be displayed
when you attempt to format the hard disk drive.
If you select Continue, formatting proceeds as normal.
If you do not want to continue formatting, you may have to press N several
times (depending on how many retries are performed by the upper-level
software). DOS, for example, does at least five retries before the Format utility
is actually aborted.
