Simply solve the BIOS optimization problem

The BIOS looks like a very unpredictable look. It seems that computer genius can do it. Actually, ordinary users can do it. You can do it with a few methods.

How to optimize the computer BIOS, for those who use the computer, you should have a good understanding, in order to facilitate your own use of the computer to work and study easily. Below we will introduce you to the optimization of the BIOS, I hope to help friends who want to know this.

To enter the BIOS setup, type DEL at the system startup (or the prompt on the first screen when booting, the usual prompt is: Press Delete to setup, or other similar sentence). If your BIOS doesn't work or you can't get into the CMOS settings, you'll need to download TweakBIOS, which will give you extremely simple access to CMOS and give you access to some COMS settings that you couldn't access before.

Let's first look at the options that were turned on in the default settings but were manually modified.

Turbo Frequency - Increases the clock speed by 2.5% to 5%. This setting can cause problems because it may set the CPU's clock frequency to a value that it can load. On the other hand, if it works properly, it will greatly improve the speed of the system. Not all motherboards have this option.

Quick Power On Self Test (POST) - This option speeds up POST (POST is executed when you first boot the system). Turn on this feature to reduce startup time. CPU Level 1 (L1) Cache (CPU Level 1 cache, also known as Internal Cache, internal cache) - The default value for this function should be turned on, but some people may turn it off when setting up CMOS. Turning on this feature will activate the cache in the CPU. Turning it off will greatly degrade the performance of the system, but it will increase the likelihood of overclocking success. I believe that everyone will open this feature.

CPU Level 2 (L2) Cache (CPU Level 2 Cache, also called External Cache, External Cache) - The default setting for this feature should also be turned on. Turning on this feature will activate your external cache. The external cache on the Pentium II processor runs at 1/2 of the clock frequency, while the external cache in Celeron (A) runs at the same speed as the clock. Turning off this feature will greatly reduce the performance of the system, but it will also increase the likelihood of overclocking success. If you really want to overclock, and you are sure that the impact of overclocking is the second level cache, you can turn off this feature, otherwise you should still open it. The original Celeron 266 and 300 did not have a second level cache.

Virus Warning - This feature doesn't have much to optimize, but it's definitely good to open it. It warns you when the program tries to access the boot sector or file allocation table, which can help you stop the operation when things are not getting out of hand. But this feature also affects several specific programs, especially when installing. If it causes any negative effects, turn it off.

The following set of settings has more problems because they vary on almost every computer.

Boot Up Floppy Seek Turning this feature on will cause the system to detect a 1.44MB floppy drive at boot time, which can cause a delay of about 1 to 2 seconds, so it should be turned off.

PCI/VGA Palette noop (PCI/VGA Palette Detection) - This feature can fix problems in some graphics cards. Most people should turn this feature off unless your graphics card asks you to turn it on.

Video BIOS Shadow - This function will store the basic BIOS function of your graphics card into memory so that it can be easily called at any time, so that the CPU can Read these features at a higher speed. Turning on this feature will greatly improve the performance of your system. Of course, if your graphics card operation manual asks you to turn it off, you should turn it off.

Shadow C8000 - CBFFF - These features will "mask" some hardware memory ranges. You should only cover areas that you think use hardware (such as graphics cards). If it's not certain, you can change these settings to experience changes in system performance before and after changes. This is a setting that you must look at carefully, just like Video BIOS Shadow.

DRAM Data Integrity Mode - The option allows you to choose between ECC memory and Non-ECC memory. Most computers now use Non-ECC memory, so you should choose the latter.

BIOS optimization, we will probably understand the above content, all the software and hardware functions in the computer, not a day or a few days to learn, but it takes a long time And need some professional staff to share knowledge, so that you can gradually become a computer master.

The article is very long, but it is not difficult to read it carefully. Interested users can go back and remember to try it, you can also become a computer expert.
