Step 6 Onboard I/O

Onboard I/O The Apollo III motherboard has:

• two serial ports (COM1 and COM2),

• a parallel port (LPT),

• an IDE controller on the PCI bus. The primary IDE connector is IDE1.

The secondary connector is IDE2.

• a floppy controller (FDD).

The serial and parallel port connectors are described below.

Conflicts AMIBIOS minimizes conflicts between onboard and offboard I/O devices.

AMIBIOS automatically checks the adapter cards installed in the expansion slots on the Apollo III motherboard for a hard disk or floppy controller and serial or parallel ports.

Serial Ports COM1 and COM2 are 10-pin connectors that provide an AT-compatible serial port interface. Connect the cables supplied with the motherboard to the

10-pin serial connectors. The serial port base I/O port address and other serial port settings can be selected in Peripheral Setup in WINBIOS Setup. The serial connector pinout is shown below.

Step 9 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 Test Plug 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 Errors If 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.


2 WINBIOS 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 Interface 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 Setup 37

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 Microsoft-

Compatible 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.

Entering Drive Parameters You can also enter the hard disk drive parameters. The drive parameters are:

Parameter

Type

Cylinders

Heads

Write

Precompensation

Landing Zone

Sectors

Capacity

Description

The number for a drive with certain identification parameters.

The number of cylinders in the disk drive.

The number of heads.

The actual physical size of a sector gets progressively smaller as the track diameter diminishes. Yet each sector must still hold 512 bytes. Write precompensation circuitry on the hard disk compensates for the physical difference in sector size by boosting the write current for sectors on inner tracks. This parameter is the track number on the disk surface where write precompensation begins.

This number is the cylinder location where the heads normally park when the system is shut down.

The number of sectors per track. MFM drives have 17 sectors per track. RLL drives have 26 sectors per track. ESDI drives have 34 sectors per track. SCSI and IDE drives have even more sectors per track.

The formatted capacity of the drive is the number of heads times the number of cylinders times the number of sectors per track times 512 (bytes per sector).

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 (see the Advanced

Setup section ) 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.


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.

Boot Sector Write!!!

Possible VIRUS: Continue (Y/N)? _

The following appears after any attempt to format any cylinder, head, or sector of any hard disk drive via the BIOS INT 13 Hard Disk Drive Service:

Format!!!

Possible VIRUS: Continue (Y/N)? _


Section 3 Utility

The following icons appear in this section of the WINBIOS Setup main screen:

Color Set Color Set sets the Setup screen colors.

Language If this feature is enabled, you can select WINBIOS Setup messages in different languages.

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.

Original Choose the Original icon to return to the system configuration values present in WINBIOS Setup when you first began this WINBIOS Setup session.

Optimal You 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-Safe You 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.


3 Programming the Flash ROM

All versions of the Apollo III 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

Step

4

Action

Turn power off. Make sure the computer has a working speaker.

Insert the floppy disk with the S752P.ROM file in drive A:.

Before 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.

When the flash ROM has successfully been programmed, the computer will reboot.

Bootblock BIOS Actions When you reprogram from system boot, the bootblock BIOS code:

Reads S752P.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.

S752P.ROM

S752P.ROM resides on a floppy disk and contains the updated main BIOS code. American Megatrends will provide this file when the AMIBIOS for the

Apollo III ISA motherboard must be updated.

S752P.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 S752P.ROM.

Sequence of Operation The sequence of operation and expected behavior of the bootblock

BIOS code is:

Step

1 Look for floppy disk.

2 Look for

S752P.ROM on the floppy disk.

3 Read the floppy disk.

4 Check for BIOS file size.

5 Check for Flash

EPROM.

6 Erase the Flash

EPROM.

7 Program the Flash

EPROM.

8 Continue programming the

Flash EPROM.

9 AMIFlash does a reset.

Expected behavior

The system beeps one time before the BIOS attempts to read from floppy drive A:.

S752P.ROM must be in the root directory of the floppy disk in drive A:. There is no beep if successful.

The floppy disk is read. There is no beep if this step is successful.

The BIOS file size is checked. There is no beep if this step is successful.

The BIOS looks for an Intel i28F001BX-T

Flash EPROM. It does not beep if this step is successful.

Two beeps sound when the BIOS begins erasing the Flash EPROM.

Three beeps sound when the AMIFlash Code begins reprogramming the Flash EPROM.

Four beeps sound when reprogramming has been successfully completed.

A CPU reset is generated to reboot the computer.
