What is BIOS chip?
BIOS is an acronym for Basic Input and Output
System. This program is stored in a Read-Only Memory chip on the
motherboard. Upon computer power-up, the BIOS is launched to perform various
start-up functions.
- Power-On Self Test (POST) - to test and initialize the hardware
- Loads the operating system
- Manage Setup for enhancing computer behavior
- Helps operating systems and application programs to manage PC hardware
via BIOS Run-Time Service routines
Did you programmed each chip with the latest Bios
version?
Each chip is programmed and verified with the latest Bios file which released
from the motherboard manufacturer. If you need other version, please do not
hesitate to let us know.
Can you supply an SOIC-8 BIOS chip?
We carry PLCC-32, PDIP-8 and SOIC-8 chip.
I have a Motherboard which with an SOIC-8 soldered
chip, can you help?
Probably we can help, firstly you've to accept our condition of use/policy.
For more information, click [here]
How can I find the Fujitsu-Siemens serial number?
Here you can find the serial number, click [here]
How can I find the revision or version?
The revision or version are print on the PCB or you'll find them on the sticker.
What you should do after purchased a new chip?
After purchased, please feel free to contact us regarding which board, Bios code
and revision or version you've at this moment.
How can I find the Bios code?
If you want to know, which Bios code you have! Firstly you need to remove the
Bios (silver/white) sticker (sometimes two stickers) and find the Bios code.
Here are the example, picture 1 & 2
Can I find the extractor tool in your shop?
Yes, we do the combination tool in stock for immediate request (purchase) which
can save the shipping costs.

For PDIP Bios Chip: Click [here]
How to replace a Bios chip?
With the extractor tool, will help you to remove the old chip.
My Motherboard have Dual Bios, which one I need to
change?
You have Main Bios
(M_Bios) and Backup Bios (B_Bios). Please replace the Backup Bios.
What shall I do after replaced Bios chip or How to clear the hardware CMOS &
Reset password.
Why?
You will need to clear the CMOS anytime you FLASH upgrade the BIOS or when you
forget your password to enter the BIOS for making settings.
How?
When clearing the CMOS, it's NOT done by pulling the lithium battery or DALLAS
chip off of the motherboard for a short period of time. Instead, there is a
jumper on the motherboard that clears the CMOS. The jumper varies for all
motherboards, so you will need to see which jumper applies to your motherboard.
(Please refer to your motherboard manual for jumper location.)
Here
we go...step by step.
- Turn the power off
- When removing the BIOS chip, remember the location
and direction of the notch at the edge of the chip (see picture below). The
new BIOS chip has to be placed in the same position.
- If you have 2 pins, short the two pins with a
jumper for 10 seconds or so then pull the jumper and return it back to the
default position.
- If you have 3 pins, then change the CCMOS jumper
from position 1-2 to 2-3, wait for 10 seconds, and place it back at 1-2.
- Turn the power back on and you should get an error
message indicated by 2 beeps to run the setup for CMOS.
- You will need to make the BIOS settings at this
point and you're done!
Please be very carfull.
What is Setup?
The BIOS Setup is a program essential to
optimizing and configuring the hardware and behavior of the computer. Setup
programs vary from one computer to another. Check your motherboard manual for
BIOS Setup options and settings. In general the BIOS Setup program is needed
when:
- installing or changing hardware on your system
- changing the behavior of your computer (changing date & time, enabling
or disabling special features, etc.)
- improving the behavior of your computer (changing performance speed,
adjusting shadowing or caching)
What is CMOS?
CMOS stands for Complementary Metal Oxide
Semiconductor in which your PC hardware configuration is stored. Information is
permanently saved in 64 bytes of CMOS RAM and is maintained by a battery (so
that nothing is lost after the PC is turned off). The CMOS maintains a PC´s
internal clock, controls how fast your computer reads from memory, whether or
not your CPU's cache is enabled or disabled, how fast your PCI bus communicates
with its adaptor cards, and much more. These CMOS settings can be adjusted in
the BIOS Setup. At times, the CMOS needs to be cleared - especially if you need
to flash upgrade a BIOS or when you lose your password to the BIOS Setup
program. See above message for more information on how to clear a CMOS.
What is POST?
POST is short for Power-On Self Test. It
consists of a series of diagnostic routines that automatically runs at start-up
and tests / initializes the devices on the system. The POST tests the RAM,
keyboard, and disk drives. If for some reason the tests are unsuccessful, the
computer would emit a series of beeps with an error message and code. Please
refer to your motherboard manual on how to interpret Beep Codes.
Why do I get a "CMOS checksum invalid" error message
during POST?
If you get the above error message or "Invalid
configuration, run Setup" message, the it is an indication that the CMOS battery
needs to be changed. You can find the battery in our [shop]
When will my item be posted?
Items are normally shipped the same day or next day morning.
How do I pay for my item?
We do accept paypal and for EU customers can also pay by bank transfer with
IBAN/BIC number. From the EU rules, this is free of charge for end customer. We
do not accept foreign checks or Postal orders we simply cannot cash them.
What is my tracking number?
If you have paid for International Registered Airmail(signed) which needs your
signature upon receiving, no online tracking service is provided, you will have
a tracking number and the items will be insured to most destinations.
However standard shipping is not insured to destinations and not tracking number
will be provided.
