Practical BIOS Program Setup instructions

Under normal circumstances, the user has little access to the BIOS, so the BIOS settings are very unfamiliar, the following brings you to understand the bios of those common settings, whether in the installation system, or in the resolution of computer failures, are very useful.

First, what is the BIOS

The complete BIOS in English is basic input output system, translated into Chinese is the "basic input and export systems", the BIOS is solidified to the computer motherboard on a ROM chip (EPROM or EEPROM) on a set of programs, It holds the most important basic input and output of the computer program, System setup information, post-boot self-test program and system from the start program, mainly for the computer to provide the lowest, most direct hardware settings and control.

Currently the most commonly used BIOS brands are the Phoenix Award BIOS and the AMI BIOS:

Two, several more commonly used BIOS setup

1. How to enter the BIOS setup interface

When we start the computer quickly press the keyboard in the lower right corner of the DEL key, if it is a notebook then generally press the F2 key, you can enter the BIOS setup interface, the General BIOS setup interface as follows:

2. How to set the computer startup order

A, set the computer to boot from the CD drive: first select the advanced BIOS features (the older motherboard in the BIOS FEATURE Setup), and then select Primary Boot Device (also has the motherboard called Boot sequence), Then select the CD-ROM.

B, set up the computer from the USB boot method: You can choose USB-HDD or Usb-zip (depending on the type of USB boot disk), first select Boot Device, and then pop up a device selection box, which has several options (as shown below), the general choice of USB-HDD can ( Depending on the type of USB boot disk).

3. How to set the system time

If we want to adjust the system time in the BIOS, first select Standard CMOS features, and then move the cursor to the corresponding time or date, then press the keyboard +,-key to adjust, and finally save (save method under the parameters) can be, the following figure:

4, how to set the hard disk AHCI mode

The location of the hard drive AHCI mode is generally in the Integrated peripherals Integrated device interface, first select Onchip SATA Type, then see the following three options, Native IDE/RAID/AHCI, if you need to turn off AHCI, Select Native IDE, and then select AHCI. Some notebooks may only have AHCI and ATA and the Disable option, and you can choose ATA mode as well. Also shows compatible mode compatibility, meaning that the native effect is the same.

In this particular note, the BIOS will also have a onchip SATA controller this SATA controller option (as shown below), if the system has been installed, if you choose to turn off the mode, may cause some uncertainties, so if the machine is running no problem, Generally only need to set SATA mode of operation, the controller does not need to shut down.

5, how to turn off the BIOS in the floppy interface

Today's computers basically do not use the floppy drive, but the motherboard is designed to support the floppy drive, so that the Windows system is always more than one floppy disk, in fact, it is not necessary, so you can directly in the BIOS to turn off the first choice of standard BIOS features, Then there is a drivea option to move to the item and enter, select None or disable that

6. How to restore the BIOS default configuration

Typically, after a BIOS upgrade or restore, we use the Load optimized defaults option, which loads the default best configuration preset, which allows the motherboard to function adequately. If you find a problem with the motherboard, you can try the load Fail-Safe defaults option.

7. Save BIOS settings

After the BIOS modification is complete, press the Y key of the keyboard to save and restart the computer to take effect, as shown in the following figure:

Whether it is a CD-ROM system, or a U-disk installation system, the BIOS is necessary to set up, and the above content is the user set up the BIOS is more common in several aspects, I hope that the above set up skills to bring some help.
