The computer should press the F1 key to start the cause when it is powered on

The boot needs to press the F1 key to enter, mainly because the BIOS settings and real hardware data does not match, can be divided into the following situations:
1, actually do not have a floppy drive or floppy drive is broken, and the BIOS is set up with a floppy drive, which causes to press F1 to continue.
You can disable the floppy drive.
Boot press del into BIOS, select: STANDARD CMOS FEATURES
DRIVE A (or DRIVEA[1.44MB 3.5]): Set to None
DRIVE B: Set to None

Press F10 to save and enter "Y" to return.

2, the original hung two hard disk, in the BIOS set into a dual hard drive, and then took off one of the time but forgot to change the BIOS settings, it will also appear this problem.
3, the motherboard battery does not have electricity also can cause the data to lose thereby to appear this fault.
4, reboot the system, into the BIOS setup, found that the floppy drive is set to 1.44M, but in fact there is no floppy drive in the chassis, this is set to none, troubleshooting.
A lot of people have asked this question, the following will I have encountered such issues to do a summary, I hope to help.
1. Hareware Monitor found a error,enter power MANAGEMENT setup for details,press F1 to Continue,del to enter SETUP
Chinese: monitoring function found error, enter the power MANAGEMENT Setup to see the details, press F1 key to continue the boot process, press del key to enter COMs settings.
Explanation: Some motherboards have the hardware monitoring function, you can set the motherboard and CPU temperature monitoring, voltage regulator voltage output and monitor the speed of each fan, when
The above monitoring function in the boot when found that there are abnormal conditions, then this paragraph will appear, then you can enter the COMs settings select Power MANAGEMENT Setup, on the right side of the **fan monitor**, **thermal monitor** and * * Voltage monitor** to see which part of the issue was abnormal and then solve it.
2. pri slave drive-atapi lncompatible Press F1 to Resume
It may be that your optical drive is not properly connected or faulty, preferably in CMOS, the IDE ports are set to automatic.
3. Press F1 to Continue,del to enter SETUP
Press Del to enter the BIOS after boot, select NONE in the floppy drive and press F10 to save it.
4, CMOS checksum error-defaults loaded
Press F1 to Contnue? DEL to enter SETUP
08/09/2000-i810-ite8712-6a69me1cc-00
The CMOS battery is out of power.
5, warning! CPU has been changed! Please Enter the CPU speed CMOS setup and Remember to save before exit!
This indicates that the BIOS settings were flushed out and that the BIOS (also called the CMOS settings) should be reset. Power on the "Del" key to enter the settings, see your motherboard instructions. How much is your CPU frequency? In the BIOS to choose a good FSB, the frequency multiplier is locked anyway. FSB is always 66, 100, or 133, looking at the CPU model, setting from low to high. If you are award BIOS setup, select Frequency/voltage Control (frequency/voltage controls) on the home page and use this menu to set the frequency and voltage specifically. Where "Clock by slight Adjust (clock frequency fine-tuning)" Allows you to choose the CPU clock frequency. Various motherboard BIOS settings are different, you can refer to their own motherboard specifications for adjustment.
6, CPU has been changed please re-enter CPU settings in the CMOS setup and remember to save before
Some motherboards have a FSB jumper, the default is 100MHZ, and some motherboards do not support automatic FM. All you have to do is go into the BIOS and set the FSB to your CPU standard FSB, the frequency multiplier is usually automatic setting, it is best not to overclocking.

If these solutions can not be resolved, you can check the CMOS side of the circuit is burned out of the signs, my machine is because of the circuit next to the CMOS problem, the above machine method has tried also useless, and finally a soldering iron to fix. Oh, you might as well try
