When flashing BOIS in DOS, how to flash BIOS under DOS?

It's not like you brushed like this.,Brush BIOS needs to have an award (seems to be this English name) to flash into the tool.,Then go to the Internet** BIOS file that is consistent with the motherboard model (remind you not to make a mistake, otherwise the motherboard will be scrapped),Then boot into DOS mode,Type award space BOIS (your **BIOS file name).bin,Enter can press the prompt**,Now there are also flashing tools that are intelligent,First type the name of the flashing tool (such as award),It will start an interface,There is a prompt on the interface for you to enter the location of the BIOS file,Enter the correct BIOS file into the carriage and then the next step until the flashing is completed and automatically restart,Then remind you to pay attention,Do not power off or manually restart automatically during the flashing period,Otherwise the motherboard will be scrapped if the input is wrong。 Flashing BIOS is a dangerous operation, although there are remedies for flashing errors, but it is very complicated, it is recommended that you do not carelessly flash BIOS if you don't understand

Now the new motherboard has the function of flashing BIOS in operating system mode, you can connect to the official ** automatic identification of the motherboard model is safer, of course, if your motherboard does not support it, there is no way.

It's tiring to play well, remember to add points.

You need to use a USB flash drive boot tool, and then you can flash the BIOS on the DOS.

1. Make a USB flash drive boot disk.

3. Plug in the USB flash drive to the computer, reboot, and enter the BIOS to set the USB flash drive boot priority.

4. Save the BIOS and exit, after restarting, it will enter the DOS interface (as follows), enter DIR to view the files in the USB flash drive.

5. Enter backup to back up the BIOS and generate a file in the U disk.

6. Enter update to start flashing the BIOS (the power must not be turned off during the flashing BIOS, otherwise it will fail and the machine will not be turned on).

If the message "Program ended normally" is displayed or the cursor is not moving (watch and wait), the BIOS is successfully refreshed.

2. After that, we choose to boot and click on the keyboard F12 to start PE.

3. Go to the Max DOS toolbox and go to the latest version of the tool.

4. After that, we choose pure DOS mode to enter.

5. Enter [C:] to enter the C drive, and then enter [DIR] to display the files in the drive.

6. Enter [EFIFLASH] to back up the BIOS program.

7. Enter the [Autoexec] batch file to refresh the BIOS directly.

8. Enter the refresh interface, automatically refresh, and the device will automatically restart several times after the refresh is completed.

Heavy winxp start,window does not have pure dos mode。 There is only a dos-like command prompt.

In the Start menu, type "cmd" and click OK to enter.

If you are not familiar with it, it is best to go to the computer city to buy an XP ghost disk, use it to boot, select the DOS toolbox inside, and enter the DOS mode with a few clicks. After entering, just follow the instructions in the letter.

1. After running the Ultraiso software on your computer, click "File - Open".

2. After entering the file selection interface, select the DOS system file and click "Open".

3. After opening the DOS file, click "Start-Write to Hard Disk Image".

4. After entering the Write to Hard Drive wizard interface, select the USB flash drive and click "Write".

5. After clicking, click "Yes" on the pop-up prompt interface.

6. Wait for the DOS system to finish writing, and then click Back to close the Ultraiso software.

7. After the DOS tool is made, copy the BIOS file to the root directory of the USB flash drive.

8. After the file is copied successfully, insert the USB flash drive into the computer and select to boot from the USB flash drive.

9. After the computer boots into the DOS interface, enter the flash command (BIOS batch file in the root directory): na0.

10. After entering the command, wait for the BIOS flashing to complete, and restart the computer after the flashing is completed.

2. The second step is to plug in the USB flash drive on the computer and restart the computer. Go to BIOS to set the USB flash drive boot priority.

3. The third step, after restarting, you will enter the DOS interface (as below), enter DIR to view the files in the USB flash drive. Select Start and click on the keyboard F12 to turn on PE.

4. Fourth, go to the MaxDOS toolbox, and then go to the latest version of the tool.

5. Step 5: Enter drive C and then DIR to display the files in the drive. (The power must not be turned off during the process of flashing the BIOS, otherwise it will fail and the machine will not be turned on).

6. Step 6: Enter the EFICflash backup BIOS program, and then enter the Autoexec batch file to flash the BIOS directly.

7. Enter the refresh interface, automatically refresh, and the device will automatically restart several times after the refresh is completed.

When prompted "Programendednormally" or the cursor does not move (note watchful waiting), it means that the BIOS has been refreshed successfully. Finally reboot to see if you enter the operating system normally.

You always type the command at the root of the C drive, Is your refresh file at the root of the C drive? It is recommended that you put the refresh file in a pure DOS environment, make a boot disk with a USB flash drive, and execute the refresh file in the USB flash drive. I suspect it's your dos environment that isn't exactly lacking dos commands.

It looks like you didn't go to the corresponding directory, so you can't find the program you want to execute. You start by typing:

cd 1007

, enter your command again and give it a try.

Before you get ready to flash the BIOS, I have to give you a word of advice, it is very dangerous to flash the BIOS, and if you don't do it well, your machine will not work. It's not that you can install the system and install programs and games, you can experiment casually Refreshing the BIOS has always been a headache for "rookies", because we generally refresh the BIOS in the DOS state, which is more dangerous. How do I safely flash the BIOS under DOS?

Let's talk about how to automatically flash the BIOS under DOS (take AwardBIOS as an example). First, if your system is overclocked, go back to normal, then turn off all power-management items in the BIOS settings, and turn off the BIOS cache ("Sysetm BIOS Cacheable") and graphics BIOS cache ("Video BIOS Cacheable"). Then insert a formatted floppy disk under DOS, use the "sys c a" command to copy the system files to a disk, and then copy the awardfalsh tool (usually available on the motherboard's CD-ROM) and the latest BIOS files (assuming that they are copied to a disk together, and finally create a batch file on the floppy disk, the contents are as follows:

echo off(Enter) if exist goto Enter) end end Okay, now you have the following file on the floppy disk: and. After starting the computer with a floppy disk, the computer will automatically refresh the BIOS, and if the refresh fails, you can also use this floppy disk to restore the previous BIOS.

Note: The awardfalsh flasher version must be above, after flashing, remove the floppy disk from the floppy drive, and enter the BIOS settings to adjust it again.

I don't know if you want to rewrite the BIOS data or erase the BIOS data, if so, it would be easy. You find a small button-like battery on the motherboard and press it in reverse. After 10 seconds, I unplugged it.

In this way, the data of the BIOS is emptied.

It doesn't matter if you don't have a floppy drive, you can have an optical drive, boot into DOS, copy the BIOS you want to flash to one of your FAT format disk partitions, and run it directly, you can add the parameter SN PyThe refresh format is SN PY (which is a BIOS data file).

Copy the AwardFalsh tool (usually available in the motherboard CD) and the latest BIOS file to the D: Drive the system disc to boot to the DOS (if your system can enter the DOS, that is, you can choose the DOS boot at the time of boot, and the system CD is not required) D: Enter the awardfalsh ?

Follow the software instructions provided by ** to refresh Flashing the BIOS is dangerous.

Motherboard BIOS flashing method collection There are actually two ways to flash the motherboard BIOS: one is to use a floppy disk in the DOS environment, and the other is to use a dedicated BIOS flashing software to flash the motherboard BIOS under the Windows operating system. In terms of convenience, of course, it is easier and more convenient to complete the refresh under the operating system.

Next, the author will introduce how to flash the motherboard BIOS under the Windows operating system. Preheat.

Flashing the BIOS is very dangerous, there is a little difference in the BLOS model of the brush, it is possible that your motherboard will be reimbursed, and it can only be flashed under the DOS, if your motherboard really needs to be flashed, it is recommended that you take it to the computer city, dozens of dollars can be refreshed soon, and it will not be very troublesome!

There's no need to refresh because there are no bugs on this motherboard for the time being, so there's nothing that can be fixed.

In win, there are more programs running, and the disturbance of flashing BIOS is also greater, and it is possible that it will be stuck and unable to respond, so when flashing BIOS under win, it is best to turn off unnecessary and irrelevant programs to avoid being affected or even implicated.

Under DOS, there are fewer programs to run, and the BIOS is less disturbed, making it easier to complete smoothly.

Comparison can be seen,WIN system is more advanced than DOS system,The more programs run,The easier it is to get stuck、Crash,However, the BIOS must be done in one go,Once brushed,If you stop halfway,For example, if you don't finish brushing,The program no longer responds,Or the system restarts,There or the computer is powered off,Then the BIOS can't be used,You can't continue to brush,You can only use a special device to brush again。 At this time, you can't even turn on the machine, let alone enter any system.

In fact, for now,Many manufacturers have provided tools and software for brushing BIOS under win,Simple and practical,And the probability of success can be said to be basically 100%There is no need to enter DOS。
