How to Reflash Motherboard BIOS About updating BIOS... The whole BIOS updating procedure should be treated with extreme caution. If you do not encounter any system instability or bugs with the current BIOS version, we suggest that you keep it. If you determine to flash BIOS, you are taking a personal risk of BIOS flash failure. Please contact your supplier or our distributors/resellers for further remedy in case system crashes unfortunately because of BIOS flash failure. Before you begin... 1. Please make sure the BIOS version you want to flash matches your motherboard model. 2. If your BIOS is flash protected, please do not enable BIOS Flash Protection under Advanced CMOS Setup (AMI BIOS) or Advanced BIOS Features (AWARD BIOS) in BIOS menu. 3. Never interrupt when you BIOS is being updated. 4. Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction. Three BIOS Flash Utilities... We provide three BIOS flash utilities at our website. Below are the overviews. 1 : flashbios_qflash.gif A BIOS flash utility embedded in Flash ROM. Not all motherboards have the Q-Flash, please use @BIOS or DOS flash utility to update BIOS if your motherboard does not have Q-Flash. Features-- With this utility, you only have to stay in the BIOS menu when you want to update BIOS. No need to enter DOS or O.S. mode. Caution-- Make sure you have a functional floppy disk with the correct BIOS version for your motherboard. UEFI - Download PDF User Guide pdf.gif Download PDF User Guide pdf.gif 2 : flashbios_atbios.gif A Windows-based BIOS live update utility. Features-- @BIOS helps you search for, download, and then update the latest BIOS in Windows operating system. Caution-- Make sure your O.S. environment is stable. UEFI - Download PDF User Guide pdf.gif Download PDF User Guide pdf.gif 3 : DOS Flash utility Features-- The flash utility is a combination of AMI and AWARD BIOS flash utility. You can use it with both AMI and AWARD BIOS. Caution-- Make sure you have a functional DOS boot disk with the correct BIOS version for your motherboard.

FLASHING BIOS - THE PROCEDURE


BIOS Update Procedure

All latest Motherboards today,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component. With
FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading.
Most pre-Pentium motherboards do not have a Flash BIOS. The following instructions therefore do not apply to these boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to use an EPROM programmer to re-program the BIOS chip. See your dealer for more information about
this.

Please read the following instructions in full before starting a Flash BIOS upgrade:

A. Create a Bootable Floppy (in DOS)

•With a non-formatted disk, type the following:

format a:/s

•If using a formatted disk, type:

sys a:

This procedure will ensure a clean boot when you

are flashing the new BIOS.

B. Download the BIOS file

•Download the correct BIOS file by clicking on

the file name of the BIOS file you wish to download.

•Save the BIOS file and the Flash Utility file in the boot disk you have created. Unzip the BIOS file and the flash utility file. If you don't have an "unzip" utility, download the WinZip from www.winzip.com or www.pkware.com. Most CD ROMs found in computer magazines, have a shareware version of WinZip on them.

•You should have extracted two files:

Flash BIOS utility eg: flash7265.exe (for example)

BIOS eg: 6152J900.bin (example)

Use the latest flash utility available unless otherwise specified (either on the BIOS update page or in the archive file). This information is usually provided.

C. Upgrade the System BIOS

During boot up, write down the old BIOS version because you will need to use it for the BIOS backup file name.Place the bootable floppy disk containing the BIOS file and the Flash Utility in drive a, and reboot the system in MS-DOS, preferably Version 6.22

•At the A:> prompt, type the corresponding Flash

BIOS utility and the BIOS file with its extension.

For example:

flash625 615j900.bin

•From the Flash Memory Writer menu, select "Y" to

"Do you want to save BIOS?" if you want to save (back up) your current BIOS (strongly recommended), then type the name of your current BIOS and its extension after FILE NAME TO SAVE:

eg: a:\613J900.bin

Alternatively select "N" if you don't want to save your current BIOS. Beware, though, that you won't be able to recover from a possible failure.

•Select "Y" to "Are you sure to program?"

•Wait until it displays "Message: Power Off or

Reset the system"

Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system. If you write to BIOS but cannot complete theprocedure, do not switch off, because the computer will not be able to boo, and you will not be given another chance to flash. In this case leave your system on until you resolve the problem (flashing BIOS with old file is a possible solution, provided you've made a backup before)

Make sure the new BIOS version has been loaded properly by taking note of the BIOS identifier as the system is rebooting.

For AMI BIOS

Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system holding the "END" key prior to power on until you enter CMOS setup. If you do not do this the first time booting up after upgrading the BIOS, the system will hang.

BIOS Update Tips

Note:
1.Make sure never to turn off or reset your computer during the flash process. This will corrupt the BIOS data. We also recommend that you make a copy of your current BIOS on the bootable floppy so you can reflash it if you need to.

(This option is not available when flashing an AMI BIOS).

2. If you have problems installing your new BIOS please check the following:

Have you done a clean boot?
In other words, did you follow the above procedure for making a bootable floppy? This ensures that when booting from "A" there are no device drivers on the diskette. Failing to do a clean boot is the most common cause for getting a "Memory Insufficient" error message when attempting to flash a
BIOS.If you have not used a bootable floppy, insure a clean boot either

a) pressing F5 during bootup

b) by removing all device drivers on the CONFIG.SYS including the HIMEM.SYS. Do this by

using the EDIT command.

Have you booted up under DOS?
Booting in Windows is another common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS. Make sure to boot up to DOS with a minimum set of drivers.

Important:
Booting in DOS does not mean selecting "Restart computer in MS-DOS Mode" from Windows98/95 shutdown menu or going to Prompt mode in WindowsNT, but rather following the above

procedure (format a: /s and rebooting from a:\).Have you entered the full file name of the flash utility and the BIOS plus its extension?
Do not forget that often you will need to add a drive letter (a:\) before flashing the BIOS.

Example: when asked for file name of new BIOS file which is on your floppy disk, in case you're working from c:\ your will need to type

a:\615j900.bin, rather than 615j900.bin only.

How do i flash my motherboard


There are thousands of motherboard nomenclatures so my response is old school/new school and perhaps not specific to your motherboard.

This is very simple trick to upgrade the BIOS of your motherboard (take Award BIOS as an example).

Above all, if your computer is overclocking, you need to adjust the clock to its normal state. The next, you should disable all items of the Power Management in the BIOS, and disable the System BIOS Cacheable as well as Video BIOS Cacheable.

Then in DOS insert a formatted floppy disk to your floppy drive (possibly external), copy all system files to Disk (A :) as dictate "SYS C** A**", you also need to copy the AwardFlash utility (in the disk came with your motherboard) and the latest BIOS files (named it as newbios.bin) to Disk (A :), finally create an autoexec.bat as below:

@echo off (press Enter key)

if exist oldbios.bin goto awdflash.exe newbios.bin oldbios.bin/py/sy/cc/cp/cd/sb/rgoto (press Enter key)

I try update my bio on my ao0751h netbook acer, and doesn't successfully, now my netbook doesn't turn on. How i recovery a bios?


Solution 1: Boot-block BIOS
Modern motherboards have a boot-block BIOS. This is small area of the BIOS that doesn't get overwritten when you flash a BIOS. The boot-block BIOS only has support for the floppy drive.If you have a PCI video card,you won't see anything on the screen because the boot-block BIOs only supports an ISA videocard.
Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy and execute it automaticly by putting awdflash *.bin in the AUTOEXEC.BAT file.
AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette. Copy and rename the correct BIOS file on the floppy and power up the PC. The floppy doesn't need to be bootable. You will see the PC read the floppy, after about 4 minutes you will hear 4 beeps, this means the transfer is done. Reboot the PC and modify the CMOS for your configuration.
Solution 2: Get a new BIOS chip
  1. Contact your motherboard manufacturer to see if they sell BIOS chips. Some motherboard manufactures send them for free.
  2. Contact a company that sells pre-flashed chips, like Unicore Software, FlashBIOS.ORG, BadFlash or Bios World
Solution 3: Hot-swapping
Note: I'm not responsible for any damage this method may do to you or your computer !
  1. Replace the corrupt chip by a working one. The best option is to take the working BIOS chip from a motherboard which has the same chipset although that's not absolutely necessary. It just has to give you a chance of booting into DOS. Before pulling the working BIOS chip out of it's original motherboard, set the System BIOS cacheable option in the BIOS to enabled.
  2. After you have put the working BIOS in the motherboard with the corrupt BIOS boot the system to DOS (with a floppy or HD).
  3. Now replace (while the computer is powered on) the working BIOS chip with the corrupt one.
  4. Flash an appropriate BIOS to the corrupt BIOS and reboot.

Solution 4: (for Intel motherboards)
  1. Change Flash Recovery jumper to the recovery mode position (not all products have this feature)
  2. Install the bootable upgrade diskette into drive A:
  3. Reboot the system
  4. Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.
  5. Turn the system off
  6. Change the Flash Recovery jumper back to the default position
  7. Leave the upgrade floppy in drive A: and turn the system on
  8. Continue with the original upgrade

Gigabyte Motherboard wont flash bios


your bios has been corrupted.

The AWARD BIOS has a similar procedure to AMI. To recover an AWARD BIOS you will need to create a bootable floppy diskette and add the desired BIOS file (we recommend using the most recent). Award BIOS's generally are in .BIN format, where as AMI was .ROM format. You will also add an AWARD flash utility (usually awdflash.exe) and an AUTOEXEC.BAT file.

The AWARD BIOS does not automatically restore the BIOS information to the 'system block' like the AMI BIOS does. You will need to add the commands necessary to flash the BIOS in the AUTOEXEC.BAT file. The system will run the AUTOEXEC.BAT file, which contains the flash instructions.

Note: 12345678.BIN represents the name of your BIOS.

Step by Step:
1. Create a bootable floppy diskette or bootable dos cd /usb drive
2. Copy the BIOS file and flash utility to the disk
3. Create an text file with any standard text editor and add the following lines

@ECHO OFF
awdflash 12345678.BIN /py/sn/f/cc/r

Exchange the awdflash with the name of whatever flash utility you are using, and replace the 12345678.BIN with the name of the BIOS file you are using. The parameters are explained here:

py = program yes
sn = save no
f = flash
cc = clear cmos
r = reboot

Remove disk and restart computer

Award BootBlock V1.0


Hi.

The BIOS (Basic Input output System) on your motherboard has become corrupted and the computer can't boot normally. The Bootblock is a "failsafe" device that allows the computer to boot far enough to use the floppy disk drive, even though the rest of the BIOS code is scrambled.

How do you think this happened? The most common cause is people trying to "update" the BIOS and messing up the flashing process. Sometimes some particularly nasty viruses can wreck the BIOS code as well.

Now this might be fixable. You will need to download a known good BIOS from Iwill's website and the Award BIOS flashing utility. Then you will need a bootable floppy disk (DOS) to start the computer. You will have to copy the BIOS .BIN file over to the floppy beforehand and the flashing utility. There will be information on the Iwill website on how to flash the BIOS.

Here is a full detailed webpage on how to go about all this:

http://pages.sbcglobal.net/jefn/bootblock.html

I just did a quick Google search using the motherboard details you provided and came up blank ....

If you can't get the BIOS flashed and usable again then I'm afraid it's time for a new motherboard/computer.

Biostar P4M900-M7 SE BIOS ROM Checksum Error


The bios upgrade procedure stopped at half , leaving the bios corrupted. The computer now cannot do a regular boot procedure, this is the reason why it cannot recognise some device. If you are still able to boot from floppy, you can restart bios upgrade procedure from floppy. Just download floppy version upgrade and re do setup. Even if you do not find latest bios version, just download a floppy upgrade that is working, so that you can restart your machine regularly , and then do the update to latest version.
If you are not able to complete the bios setup, the only way to fix your motherboard will be flashing the CMOS chipset with a chip programmer device that will reinstall bios straight into cmos chipset.
You can have this done at the service point, in this case consider also replacing your motherboard.
