To turn on the computer, you need to press the keyboard to enter

It is a virtual floppy disk system. The bootloader is placed in the MBR and occupies the first 3 sectors of the disk, which means that the installation needs to write data to the 3 sectors starting from the MBR, so if an error occurs at this time, it may be that the system cannot boot.

A detects the soft zone when entering the BIOS to close boot, (note: not to say that the order of the drivers is a problem) regardless of whether you have a soft zone or not, or what boot order is set.

B See that you don't have a soft area, find a disc that can boot to DOS, set the disc to boot into DOS, enter the command fdisk mbr to repair the boot area, and the problem can be solved.

The first floor is right, but it is enough to block the floppy disk.

It may be that the motherboard coin cell battery is dead.

Go to the motherboard BIOS settings and change the first boot item to a hard diskIf the motherboard is out of power, change it every time you turn it on.

Boot and press del to enter the BIOS,Generally select the first item to enter,Press Xiangjian to select a "what,Enter,Select "none" and then press F10 to save,Restart,OK。

Try changing the coin cell battery of the motherboard.

Poisoned. Kill the virus first. If that doesn't work, reinstall the system. Install the Restore Wizard. It will be better in the future!

Before the computer is connected to the power, the keyboard cannot perform any operation, so it cannot be turned on through the keyboard, but can only be turned off.

Turn on the computer with a keyboard, select "powerkey", and use a separately designed power button on the keyboard to power on, but only some keyboards that meet the technical specifications of keyboard98 support this function. Of course, the power button on the case will still work. As for booting up with a mouse, the settings in the BIOS are similar to the keyboard boot settings, and then the computer can be started with just a few clicks of the mouse button.

If you want to use the keyboard to boot on, you must turn on the function in the main menu of the BIOS of the motherboard, and the keyboard boot is required, at this time, you can check the manual, check whether your computer supports keyboard boot, if it does, just enable the keyboard boot method in the BIOS, and then set a boot key by yourself, you can Huaichun.

The advantages of keyboard boot are very obvious, making computer boot more convenient and more personalized; Prerequisites for keyboard boot on:

1. The motherboard chipset and BIOS support the keyboard boot function

Because using a keyboard to turn on the lead air resistance machine, it must be set in the BIOS, and the "IO chip" on the motherboard is required to support keyboard booting, and the version of the BIOS can determine whether your computer supports using the keyboard to boot on, so it is recommended to upgrade the motherboard BIOS to a newer version.

2. The computer must use ATX power supply: deficit section.

ATX is currently a newer power supply, most computers currently use this power supply, if your computer uses AT power supply, then it cannot be set to boot through the keyboard.

3. Different boot methods:

Some simple keyboards can only be turned on with a fixed few hotkeys, while some powerful motherboards can be customized with boot hotkeys, and can be powered on using key combinations, and some advanced motherboards may also be powered on by a mouse.

Prerequisites for keyboard boot on:

1.The computer must be powered by ATX.

If it is an "old-fashioned" AT power supply, then it is recommended that you give up! Given that ATX power supplies have been "on the rivers and lakes" for several years, as long as the CPU is not Intel

MMX or AMD

Computers below K6 are believed to use ATX power supplies.

2.The motherboard chipset and BIOS support the keyboard boot function.

The "IO chip" on the motherboard needs to be able to support keyboard booting. In addition, the level of the motherboard BIOS version will also affect whether you can implement the keyboard boot function, it is recommended to upgrade the motherboard BIOS to a newer version.

3.The keyboard boot function of the computer can be defined in different ways according to the strength of the "io chip" function.

For example, a simple keyboard boot can only boot the computer with a few fixed hotkeys. Some motherboards use a more advanced keyboard boot method, which can not only realize "password" boot, "custom key combination" boot, but also "mouse" boot. These more advanced boot methods make your boot more personalized.

How to turn on the keyboard.

1.Turn on the keyboard boot function by setting the motherboard jumper.

Taking the MSI i815E motherboard as an example, in order to turn on the keyboard, you must first connect the JP1 jumper on the motherboard (keyboard

poweron

selection) to "1 2" state to realize the keyboard boot function of the motherboard. As we can see from Figure 1, the motherboard has the keyboard boot function disabled by default. According to the default setting of this jumper, no matter how you set it in the BIOS, the keyboard boot function will not be realized.

This is why many users complain that the BIOS of the motherboard can support the keyboard boot function, but it has never been able to do so. Therefore, it is recommended that you should carefully read the motherboard manual when installing the computer for the first time to avoid detours.

Figure 1: The default setting for some motherboards is to disable the keyboard boot function.

2.In the motherboard BIOS, set the keyboard boot parameters.

After powering on, press the "Delete" key on the keyboard to enter the BIOS settings menu (as shown in Figure 2). In most cases, the keyboard boot parameters can be set in the "integrated

peripherals" (integration of peripherals). A small number of motherboards (early motherboards) have keyboard boot parameters via "power."

Once we are on the BIOS settings screen, move the "cursor" to "Integrated."
