Press the F 1 key when starting the machine. This is because your BIOS settings are incorrect, but you can start the system normally, which is not a fatal failure. Press F 1 to ask if you want to continue.

You don't have a floppy drive installed, but the option to open the floppy drive is set in CMOS.

The method is: press the Del key, enter the BIOS settings, select the first "basic settings", and a floopy setting without "Disabel" will be invalid.

2 at the beginning of the boot, press the DEL key to enter the BIOS, and press the enter key to enter the first item to see if the "Drive A" item inside is "none"; If not, press "Pgup" or "PgDn" to modify, press "ESC" to exit after modification, and select "Save &; Exit Settings "item Press Enter to exit the BIOS and restart. If not, just change the battery and reset it according to the above steps.

3 boot need to press the F 1 key to enter, mainly because the BIOS settings are inconsistent with the real hardware data, which is divided into the following situations:

1, actually there is no floppy drive or the floppy drive is broken, but there is a floppy drive in the BIOS, which leads to pressing F 1 to continue.

2. Originally, two hard disks were hung up and set as dual disks in the BIOS, but later, when one of them was removed, I forgot to change the BIOS settings back, and this problem will also occur.

3. The motherboard battery failure will also cause data loss.

4. Restart the system and enter the BIOS settings. It is found that the floppy drive is set to 1.44M, but there is no floppy drive in the chassis. After setting this to "None", troubleshoot.

Many people have asked this question before. Here is a summary of the problems I have encountered, hoping to help everyone.

1, hardware monitor found an error, enter the power management settings for details, press F 1 to continue, and press DEL to enter the settings.

If the monitoring function finds an error, enter the power management settings to check the details, press F 1 to continue the boot program, and press DEL to enter the COMS settings.

Note: Some motherboards have hardware monitoring function, which can set the temperature monitoring of the motherboard and CPU, the voltage output level monitoring of the voltage regulator, and the speed monitoring of each fan.

The above monitoring function found abnormal when it was turned on, so the above passage will appear. At this point, you can enter COMS settings and select power management settings. On the right, * * fan monitoring * *, * * thermal monitoring * * and * * voltage monitoring * * see which part is abnormal, and then solve it.

2. If pri slave driver -ATAPI ln is not compatible, press F 1

Maybe your CD-ROM drive is not connected properly or it is faulty. In CMOS, it is best to set each IDE port to automatic.

3. press F 1 to continue, and press DEL to enter the setting.

Press DEL to enter the BIOS after booting, and press F 10 to save after selecting NONE in the floppy drive.

4. CMOS checksum error-default value has been loaded

Press F 1 to continue? Delete to enter settings.

The cmos battery is dead.

5. Warning! The CPU has been changed! Please enter the CPU speed CMOS setting, and remember to save it before exiting!

This shows that the BIOS settings have been washed away, and it is necessary to reset the BIOS (also known as CMOS settings). Press and hold the "Del" key to enter the settings and read your motherboard manual. What is your CPU frequency? Select the external frequency in the BIOS, and the frequency doubling is locked anyway. The external frequency is always 66, 100 or 133, depending on the CPU model, set from low to high. If it is the BIOS setting of AWARD, select the frequency/voltage control on the home page and use this menu to make special settings for frequency and voltage. Among them, "clock fine tuning" allows you to select the CPU clock frequency. There are differences in BIOS settings of various motherboards, so you can refer to your own motherboard manual for adjustment.

6. The cpu has been changed. Please re-enter the cpu settings in cmos settings and remember to save them before exiting!

Some motherboards have external frequency jumpers, the default is 100MHZ, and some motherboards do not support automatic frequency modulation. You just need to enter the BIOS and set the external frequency to your CPU standard external frequency. Frequency doubling is usually set automatically, so it is best not to overclock.

If the above solutions can't be solved, you can check the circuit next to CMOS for signs of burning out. My machine is because there is something wrong with the circuit next to CMOS. All the above solutions have been tried, but it's useless. Just use the last soldering iron.
