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.
Apollo III PCI Pentium ISA Motherboard User’s Guide

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
Hit <DEL> if you want to run SETUP
Press <Del> to run WINBIOS Setup.
As POST executes, the following appears:

Parameter
Description
Type
The number for a drive with certain identification
parameters.
Cylinders
Heads
The number of cylinders in the disk drive.
The number of heads.
Write
The actual physical size of a sector gets progressively
Precompensation 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.
Landing Zone
Sectors
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.
Capacity
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).

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.

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.
