Step 6 Attach Cables, Continued
Attach IDE Cable P1 is the primary IDE (Integrated Drive Electronics) hard disk drive
connector. Both the primary master and the primary slave IDE drives must be
connected by cable to P1, as shown below.
P1 is a 40-pin dual-inline berg that connects an IDE drive to the primary
onboard IDE connector. This motherboard supports IDE Modes 0, 1, 2, 3, and
4, IDE prefetch, LBA (Logical Block Address) mode, high capacity drives
(over 528 MB), 32-bit data transfer, and fast IDE transfer. These IDE features
are configured in Peripheral Setup in the WINBIOS Setup utility.
Disable the onboard IDE interface in Peripheral Setup to use an ISA ESDI,
RLL, MFM, or SCSI hard disk drive controller.
Bus Master IDEThe Titan III EISA motherboard supports bus master IDE. When connecting
a device that uses bus master IDE, make sure that the IDE Bus Master option
in Peripheral Setup is set to Enabled.
Make sure that J4 and J30 are shorted if using bus master IDE. When bus
master IDE is enabled, PCI slot 4 (P19) does not support a PCI bus master
card.

Step 7 Test and Configure
Review the following points before powering up:
• make sure that all adapter cards are seated properly,
• make sure all connectors are properly installed,
• make sure the CPU is seated properly,
• make sure there are no screws or other foreign material on the
motherboard,
• plug the system into a surge-protected power strip, and
• make sure blank back panels are installed on the back of the chassis to
minimize RF emissions.
Start the TestPlug everything in and turn on the switch. If there are any signs of a problem,
turn off the unit immediately. Reinstall the connectors. Call Technical
Support if there are problems.
BIOS ErrorsIf the system operates normally, a display should appear on the monitor. The
BIOS Power On Self Test (POST) should execute.
If POST does not run successfully, it will beep or display error messages.
Beeps indicate a serious problem with the system configuration or hardware.
The Beep Code indicates the problem. AMIBIOS Beep Codes are defined in
the AMIBIOS Technical Reference. Make sure the affected part is properly
seated and connected. An error message is displayed if the error is less
serious. Recheck the system configuration or the connections.
Configure the System Run WINBIOS Setup. You must enter the requested information and
save the configuration data in CMOS RAM. The system will then reset, run
POST, and boot the operating system. See the following chapter for
information about configuring the computer.

2WINBIOS Setup
In ISA and EISA computers, the system parameters (such as amount of
memory, type of disk drives and video displays, and many other elements) are
stored in CMOS RAM. Unlike the DRAM (dynamic random access memory)
that is used for standard system memory, CMOS RAM requires very little
power. When the computer is turned off, a back-up battery provides power to
CMOS RAM, which retains the system parameters. Every time the computer
is powered-on, the computer is configured with the values stored in CMOS
RAM by the system BIOS, which gains control when the computer is powered
on.
The system parameters are configured by a system BIOS Setup utility.
Historically, BIOS Setup utilities have been character-based, required
keyboard input, and have had user interfaces that were not very intuitive.
Graphical BIOS Setup American Megatrends has a new type of system BIOS Setup utility.
WINBIOS Setup has a graphical user interface the end user can access using
a mouse. The WINBIOS Setup code is so compact that it can reside on the
same ROM as the system BIOS. The system configuration parameters are set
by WINBIOS Setup.
Since WINBIOS Setup resides in the ROM BIOS, it is available each time the
computer is turned on.
Starting WINBIOS Setup As POST executes, the following appears:
Hit <DEL> if you want to run SETUP
Press <Del> to run WINBIOS Setup.
Chapter 2 WINBIOS Setup33
Using a Mouse with WINBIOS Setup
WINBIOS Setup has a built-in mouse driver and can be accessed by either a
serial mouse or PS/2-style mouse. WINBIOS Setup supports MicrosoftCompatible serial mice and all PS/2-type mice.
The mouse click functions are: single click to change or select both global
and current fields and double-click to perform an operation in the selected
field.
Using the Keyboard with WINBIOS Setup
WINBIOS has a built-in keyboard driver that uses simple keystroke
combinations:
KeystrokeAction
<Tab>Change or select a global field.

The standard AT-compatible parallel port mode is used.
The parallel port can be used with devices that adhere to the
Enhanced Parallel Port (EPP) specification. EPP uses the
existing parallel port signals to provide asymmetric
bidirectional data transfer driven by the host device.
The parallel port can be used with devices that adhere to the
Extended Capabilities Port (ECP) specification. ECP uses the
DMA protocol to achieve data transfer rates up to 2.5
Megabits per second. ECP provides symmetric bidirectional
communication.

Section 2 Security
Three icons appear in this part of the WINBIOS Setup screen:
• Supervisor (Password),
• User (Password), and
• Anti-Virus.
Two Levels of Passwords Both the Supervisor and the User icons configure password support.
If you use both, the Supervisor password must be set first.
The system can be configured so that all users must enter a password every
time the system boots or when WINBIOS Setup is executed, using either or
both the Supervisor password or User password.
AMIBIOS Password Support
The Supervisor and User icons activate two different levels of password
security. If
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.

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 is run). The
password is encrypted and stored in NVRAM.
As shown on the above screen, you are prompted for a 1 – 6 character
password. You can either type the password on the keyboard or select each
letter of the password, one at a time, using the mouse. The password does not
appear on the screen when typed. Make sure you write it down. If you forget
it, you must drain NVRAM and reconfigure.
If You Do Not Want to Use a Password Just press <Enter> when the password prompt
appears.
Chapter 2 WINBIOS Setup57
Changing a Password
Select the Supervisor or User icon from the Security section of the WINBIOS
Setup 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>. The password is stored
in NVRAM after WINBIOS completes. The next time the system boots, a
password prompt appears if the password function is present and enabled.
Remember the Password Keep a record of the new password when the password is changed. If
you forget the password, you must erase the system configuration information
in NVRAM (Non-Volatile Random Access Memory).
Anti-Virus
When this icon is selected from the Security section of the WINBIOS Setup
main menu, AMIBIOS 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, 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.

Section 4 Default
The icons in this section permit you to select a group of settings for all
WINBIOS Setup options. Not only can you use these icons to quickly set
system configuration parameters, you can choose a group of settings that have
a better chance of working when the system is having configuration-related
problems.
OriginalChoose the Original icon to return to the system configuration values present
in WINBIOS Setup when you first began this WINBIOS Setup session.
OptimalYou can load the optimal default settings for the WINBIOS by selecting the
Optimal icon. The Optimal default settings are best-case values that should
optimize system performance. If NVRAM is corrupted, the Optimal settings
are loaded automatically.
Fail-SafeYou can load the Fail-Safe WINBIOS Setup option settings by selecting the
Fail-Safe icon from the Default section of the WINBIOS Setup main menu.
The Fail-Safe settings provide far from optimal system performance, but are
the most stable settings. Use this option as a diagnostic aid if the system is
behaving erratically.

3Programming Flash ROM
All versions of the Titan III PCI EISA motherboard use Flash EPROM to
store the system BIOS. The advantage of Flash EPROM is the EPROM chip
does not have to be replaced to update the BIOS. The end user can actually
reprogram the BIOS, using a ROM file supplied by American Megatrends.
Programming the Flash EPROM
StepAction
1Turn power off. Make sure the computer has a working speaker.
2Insert the floppy disk with the S729P.ROM file in drive A:.
3Before DOS boots, press and hold down the <Ctrl> and
<Home> keys to reprogram the Flash EPROM-based AMIBIOS.
The bootblock code immediately reads the A: drive, looking for
the new BIOS information.
4When the flash ROM has successfully been programmed, the
computer will reboot.
Boot Block BIOS Actions When you reprogram from system boot, the boot block BIOS code:
Reads S729P.ROM from the root directory of the floppy disk in drive A:.
Erases the Flash EPROM. Programs the Flash EPROM with the data read
from the floppy disk in drive A:. Generates a CPU reset, rebooting the
computer.
The bootblock part of the Flash EPROM is not programmed. Should you
inadvertently open the disk drive door or turn power off to the computer while
programming the Flash EPROM, the bootblock will be unaffected. Simply
turn power back on and begin the Flash ROM programming process again.

S729P.ROMS729P.ROM resides on a floppy disk and contains the updated main BIOS
code. American Megatrends will provide this file when the AMIBIOS for the
Titan III PCI EISA motherboard must be updated.
S729P.ROM must be present in the root directory of the floppy disk before the
onboard Flash EPROM can be reprogrammed. The file that has the main
BIOS code must be named S729P.ROM.
Sequence of Operation The sequence of operation and expected behavior of the boot block
BIOS code is:

Beep CodesThe bootblock code produces a series of beeps during Flash ROM
programming to:
• signify completion of a step (as shown on the previous screen), or to
• signal an error.
Error beeps are arranged in a coded sequence and have different meanings
depending on when they occur. The error beep codes and when they can occur
are:
