The BIOS is
built-in software that determines what a computer can do without accessing
programs from a disk. On PCs, the BIOS contains all the code required to control
the keyboard, display screen, disk drives, serial communications, and a number
of other functions. The BIOS is typically placed on a ROM chip that
comes on the motherboard (it is often called a ROM BIOS). This ensures that the
BIOS will always be available and will not be damaged by disk failures. It also
makes it possible for a computer to boot itself. Because RAM is faster than ROM,
though, many computer manufacturers design systems so that the BIOS is copied
from ROM to RAM each time the computer is booted. This is known as
shadowing. Most modern PCs have a flash BIOS, which means that the
BIOS has been recorded on a flash memory chip, which can be updated if
necessary. BIOS is standardized, so that all PCs are alike at
their most basic level (although there are different BIOS versions). Additional
DOS functions are usually added through software modules. This means you can
upgrade to a newer version of DOS without changing the BIOS. PC
BIOSes that can handle Plug-and-Play (PnP) devices are known as PnP BIOS's, and
are virtually always implemented with flash memory rather than ROM.
The easiest way is to
consult the manual. Barring this you will need to make a visual inspection
of the BIOS chip. Take the cover of the computer and look inside.
Look for a 28 or 32-pin DIP IC chip with the BIOS brand sticker on
it. Peel the sticker of the BIOS chip. Anything without a
Window that doesn't have a 28 or 29 as the preceding numbers of the part #, is
most likely a standard ROM and will have to be replaced if you intend to upgrade
There are several reasons to update your BIOS. Primarily due
to a multitude of peripheral devices constantly being released and the
motherboard manufacturers in a rush to get to market true compatability is hard
to achieve, so, new BIOS are written to catch up addressing bugs as they
occur. The major reason used to be Operating System compatability.
Older BIOS weren't properly configured to handle new OS's like Win95/98 or FAT
32. All harddrives that are sold today are larger then 528MB. and come in
a wide variety of SCSI and EIDE interfaces.To support these drives the BIOS must
have LBA (Logical Block Addressing) support, PIO mode 4 support, DMA support,
etc. When your BIOS doesn't support LBA et. al. and you want to use your new
drive at full it's full capability, OS's like Win95 will load virtual device
drivers in an attempt to fool the BIOS. With some of these software
drivers Windows 95 will load your HD in compatibility mode which means a
performance loss. To let Windows 95 fully support Plug 'n Play you also need a
PnP-BIOS. This is a very important reason to update your BIOS. If you are
happy with the way that your system performs and don't intend to upgrade any of
your peripherals we suggest you leave your BIOS alone. Problems have been
known to occur when attempting a flash BIOS upgrade and why open yourself up to
those headaches if you don't need to. On the other hand if your system has
problems a flash BIOS upgrade may be of great help in resolving
them.If you have a Super socket 7 mainboard you can probably find the
latest BIOS available here. If your motherboard isn't listed on the BIOS
Update Page then you will have to search for your mb. manufacturer's web site.
To flash your BIOS
you'll need 1) an executable Flash file and 2) a data-file.(most often with a
The flasher 'flashes' the data-file into the BIOS chip. Download
the files to a newly formatted bootable floppy (make sure to extract ZIP files).
With the disk in your floppy drive turn off the computer, wait 3 seconds
then turn it back on. I should boot to a DOS A:\ prompt. Type in the
name of the EXE file (typically FLASHxxx) a space, then the name of the data
file (typically xxx.bin) and hit enter. Most flashers will ask you to save
the current BIOS. Choose Yes, so that you can always flash back to the original
version if you're having problems with the one you are installing.
Some manufacturers may use their own utilities to upgrade the BIOS.
IMPORTANT! - Disable the System BIOS Cacheable option in the BIOS before
variances in the quality of the chips have generated problem reports, also, if
you use the wrong Flash BIOS, there is chance that your computer won't boot

- In BIOS Setup be
sure that the System BIOS cacheable option in your BIOS is enabled
- Replace the bad chip
by a working one. The working BIOS chip doesn't have to be written for your

for the same chipset usually work.
- Boot the system to
DOS (with floppy or HD)
- Now replace (while
the computer is powered on) the BIOS chip with the corrupt one. This works
fine with most boards because most BIOSs are shadowed to RAM.
- Flash an appropriate BIOS to the corrupt chip and reboot.
(If possible use a flasher from MRBIOS. Utilities particular to your motherboard often use
specific BIOS-hooks. Because you have booted with a BIOS not written for your motherboard
they usually don't work.
The MR Flash
utilities communicate directly with your Flash ROM and always work. In most
cases they will flash a non-MRBIOS to your BIOS chip without any

Although there have
been reports of successfully upgrading BIOS from the same maufacturer we do not
recommend that you even try. Contact your motherboard manufacturer and
question them about the availability of upcoming updates. If there are
none in the works start thinking about a new motherboard.

Award and AMI custom create motherboard manufacturers BIOS for
each specific board and the chipset(s) controlling that board. The manufacturer,
using tools from Award/AMI, make final modifications to the BIOS before shipping
the system or board. In other words, the manufacturer knows more about that
system than AMI/Award do and is better able to provide a Flash BIOS upgrade.

Flash BIOS images, specific to each motherboard manufacturer but, you should
only use these if you can't find an updated BIOS anywhere else.

PROM (an acronym for programmable read-only memory) is a memory chip
to which data can be written only once. Once written it remains there
forever. Unlike RAM, PROMs retain their contents when the computer is turned
off. The difference between a PROM and a ROM (read-only memory) is
that a PROM is manufactured as blank memory, whereas a ROM is programmed during
the manufacturing process. To write data onto a PROM chip, you need a special
device called a PROM burner.
An EPROM (erasable programmable
read-only memory) is a special type of PROM that can be erased by exposing it to
ultraviolet light. Once it is erased, it can be reprogrammed.
EEPROM (Acronym for electrically
erasable programmable read-only memory). Pronounced double-ee-prom, an EEPROM is
a special type of PROM that can be erased by exposing it to an electrical
charge. Like other types of PROM, EEPROM retains its contents even when the
power is turned off. Also like other types of ROM, EEPROM is not as fast as
RAM. A special type of EEPROM, referred to as flash memory or flash
EEPROM, can be rewritten while it is in the computer rather than requiring a
special device called a PROM reader.

beep - Refresh failure
beeps - Parity error
beeps - Base 64K memory failure
beeps - Timer not operational
beeps - Processor error
beeps - 8042 - gate A20 failure
beeps - Processor exception interrupt error
beeps - Display memory read/write failure
beeps - ROM checksum error
beeps - CMOS shutdown register read/write error
beeps - Cache memory bad
For 1 beep, 2 beeps, or 3 beeps try reseating the memory first. If the error still
occurs, replace the memory with known good chips.
For 4 beeps, 5 beeps, 7 beeps, or 10 beeps the system board must be sent in for repair.
For 6 beeps reseat the keyboard controller chip. If the error persists, check the
parts of the system relating to the keyboard, e.g. try another keyboard, make sure the
keyboard socket is correctly grounded, check to see if the system has a keyboard fuse.If
the error still occurs, replace the keyboard chip.
8 beeps indicates a memory error on the video adapter. Replace the video card or the
memory on the video card.
9 beeps indicates faulty BIOS chip(s). It isn't likely that this error will be corrected
by reseating the chips. Consult the motherboard supplier or an AMI product distributor for
If no beeps are heard and no display is on the screen, The first thing to check is the
power supply. Connect a LED to the POWER LED connection on the motherboard. If this LED
lights and the drive(s) spin up then the power supply will usually be good.
Then; inspect the motherboard for loose components. A loose or missing CPU, BIOS chip, Tag
RAM, or Chipset chip will cause the motherboard not to function properly.
Next, eliminate the possibility of interference by a bad or improperly set up expansion
card by removing all cards except for the video adapter. The system should at least power
up and wait for a drive time-out. Insert the cards back into the system one at a time
until the problem happens again. When the system does nothing, the problem will be with
the last expansion card that was put in.
above suggestions fail to cause any change in a malfunctioning system, the
motherboard must be returned for repair.
